1.Is the design of plastic injection mold manufacturers protected by intellectual property rights?
The design and manufacture of a mould often requires great effort, skill and expenditure by a proprietor. As such, it is of great importance to a proprietor that their mould is protected so as to prevent competitors from copying it and gaining an unfair advantage. Fortunately, intellectual property laws in South Africa provide ample protection possibilities to a proprietor of a mould. This article gives an overview of the types of intellectual property which could protect a mould. Patent protection A mould would qualify for patent protection if it is new, involves an inventive step and is useful in trade, industry or agriculture. The novel and inventive merit of the mould would be assessed with reference to the so-called “prior art”. The “prior art” includes all matter which has been made available to the public anywhere in the world, through written or oral description, use or in any other way. However, it is important to note that if a patent has been granted for a mould, the patent would not extend to an article which has been manufactured with the mould. Design registration protection A mould may also qualify for protection as a functional design registration provided the mould is new and not commonplace in the art in question. A functional design protects the pattern, shape or configuration of an article, having features which are necessitated by the function which the article is to perform. As is the case with the law of patents, if a functional design registration has been registered for a mould, the functional design registration would not extend to an article which has been manufactured with the mould. Copyright protection In terms of the Copyright Act, a mould qualifies as an artistic work. Copyright will subsist in the mould if the mould was made by a qualified person and if the mould is original. Here, the term “original” means that the author of the work (i.e. the person who makes or creates the mould) must expend enough skill and effort to give the mould a quality or character of its own. A “qualified person” includes a natural person who is a South African citizen or who is domiciled or resident in South Africa. For copyright to remain in the mould, it is of the utmost importance that three-dimensional reproductions thereof should not be made available to the public. Conclusion All of the above intellectual property rights may be used to protect a mould and various enforcement strategies may be used.
2.What changes have plastic injection mold manufacturers gone through in their journey in China?
Injection molding machine plays a crucial role in plastics processing machinery, constituting 40% to 50% of the total output value of plastics processing machinery in China. In 2019, injection molding machines made up 45.4% of China’s plastics machinery exports; and it seized a 38.1% share in China’s imports of the same kind. China’s output of injection molding machine would drop to 100,400 units in 2019 due to the depressed markets like automobile and 3C, and the figure will continue the bearish trend in the wake of the COVID-19 pandemic. As expected, China’s output of injection molding machines will recover with the demand growth from downstream markets and the motivation of replacing steel, nonferrous metals, cement and timber with plastics as well as the lightweight momentum. Of the Chinese injection molding machine producers including Haitian International Holdings Limited, The Chen Hsong Group, Guangdong Yizumi Precision Machinery, L.K. Technology Holding Limited, Borch Machinery, Tederic Machinery, etc., Haitian International Holding Limited is the largest one with its market share in 2019 reaching 34.1%. China National Chemical China (ChemChina) acquired the Germany-based Krauss Maffei and incorporated it into Qingdao Tianhua Institute Of Chemistry Engineering Co., Ltd which was later listed on Shanghai Stock Exchange and renamed on September 9, 2019 as Kraussmaffei Co., Ltd (now being the second largest producer of injection molding machines in China, seizing 20.4% market shares in 2019). Confronting the weak domestic demand and the depressed export, the Chinese manufacturers of injection molding machine strengthen their competitiveness through more efforts in the R&D and innovation of products as well as exploration of overseas markets. During 2018-2019, the leaders such as Haitian International Holdings Limited, The Chen Hsong Group, Guangdong Yizumi Precision Machinery, Borch Machinery and Tederic Machinery were pacing up their expansion abroad. Injection molding machine is heading toward the ‘electrified, large-sized, intelligent, connected’ trend alongside an ever higher demanding on the precision, stability, energy saving and efficiency from downstream sectors like 3C, medical, airplane and high-speed railways.
3.What changes have experienced in the development process of plastic injection mold manufacturers?
When you think of the great inventions of modern history you probably think of automobiles, airplanes, computers, and other revolutionary innovations. While these developments are vital, have you ever considered the multifaceted manufacturing processes, materials, and design applications their production entails? Many people are unaware of today’s invaluable manufacturing methods and tools, but without them, industrial innovations and new-age technological devices would not exist. Plastic injection molding is a perfect example. Plastic has emerged as one of the most critical mediums in modern manufacturing as it offers affordable, high-quality production runs and durable, corrosion-resistant parts and products. Plastic injection molding technology has only enhanced the design and application capabilities of plastic materials. The modern world would look drastically different without plastic injection molding. Let’s dig a bit deeper into it’s history. The Start of Plastic Injection Molding Plastic injection molding was invented in the late 19th century, with the first molding machine patented in 1872 by two brothers, John and Isaiah Hyatt. While the device was simple by today’s standards, it quickly led to the growth of a nascent plastic manufacturing industry, where combs, buttons, and other simple articles were molded in plastic. In 1903 two German scientists, Arthur Eichengrun and Theodore Becker, created soluble forms of cellulose acetate; this was significantly less flammable than previous alternatives. While the 1930’s were a dark time for many people, for the plastics manufacturing industry it was a decade of innovation. Many of the most popular thermoplastics, such as polyolefins, polystyrene, and polyvinyl chloride (PVC) were invented during this time. World War Two and the Brave New World World War Two reshaped human history. The Second Great War popularized airplanes, led to dramatic advancements in automotive technology, and enhanced the United States war manufacturing economy that would later power the first stage of the post-war industrial revolution. Regarding plastics, this period also elicited a high demand for inexpensive, mass-produced materials. This demand following World War II was in part a result material shortages. For example, rubber production was disrupted by the war across Asia and attacks on shipping lanes. Tanks and other war applications created a huge demand for metal. Plastics stepped in to fill the gap, providing an affordable substitute. As plastics gradually popularized, so too did plastic injection molding. It’s effectiveness to this era was primarily attributed to efficient, affordable, large-scale manufacturing. Throughout the post-war period plastics remained popular. As business leaders recognized the tremendous cost benefits over rivaling materials, global supply chains were reevaluated, and plastics became firmly entrenched in the mid-20th century’s economy and manufacturing processes. James Watson Hendry and the Modern Plastic Injection Molding Industry By 1946, American inventor James Watson Hendry built the world’s first extrusion screw injection machine. Using a rotating screw, Hendry was able to better control the injection process itself. This dramatically increased the quality of the products produced. Hendry wasn’t done after creating the extrusion screw injection machine. Far from it. Hendry went on to develop the first gas-assisted injection molding process, a pivotal innovation that allowed for the creation of long, complex, hollow products. With materials providing increased strength and reduced weight, plastic production had overtaken steel production by the 1970s. By 1990 aluminum molds had become a manufacturing trend; a faster, cheaper production alternative to steel molds. Hendry is one of the most important names in manufacturing history. Without his inventions, plastic injection molding would not be as advanced as it is today. The Current State of Plastic Injection Molding Today, the opportunities provided by plastic injection molding are implemented by essentially every manufacturing sector; electronics, automotive, home appliances, housewares, you name it. Plastic Injection Molding is an affordable and effective method of producing high-quality parts and products. The technology used today is quite similar to the technologies used in the past. However, computers have made the whole design and manufacturing process easier. The results are also more precise, and now plastic parts are often the preferred choice for advanced technological and scientific applications. Conclusion: The Future of Plastics Is Here New Berlin Plastics is proud to have been a part of the history of plastic injection molding. Founded in 1975, New Berlin Plastics has built an experienced team that has been able to produce some of the highest-quality plastic products available for a wide variety of industries.
4.How do plastic injection mold manufacturers ensure the accuracy and consistency of their products?
A quality control system is a necessity for companies that use injection molding. When items don’t work, aren’t the right color, or don’t fit correctly, it can damage a company’s reputation. It starts at the design phase and includes discussions about surface finishes affecting aesthetics and performance. The best way to ensure your injection molded product works is to partner with a manufacturer prioritizing precision, consistency, and durability. Part Lines The injection molding process is highly controlled and can ensure consistent results. Nevertheless, even with this high level of quality control, mistakes can sometimes occur. These errors may lead to products not being made according to specifications and can upset customers. A standard error in injection molding is the creation of part lines. These unsightly seams can form when different product parts come together. While good design can hide these lines, poor production quality makes them appear more prominent and cheap. Machinists must select the best location for the parting line during mold design to avoid this issue. The part’s geometry usually determines this and how it needs to be drafted for release. Simple techniques will have a parting line that exists on a flat plane, while more complex and curved designs will require a parting line to follow the contour of the product. Insufficient Plastic If your injection molded products don’t fit, are the wrong color, or have flaws in the design, you’ll upset customers and may even lose business. That’s why rigorous quality control is essential. Discolored lines appear on the surface of finished molded parts and are most commonly caused by the plastic resin cooling at different rates as it flows through the mold. They can also result from uneven wall thickness or varying injection speed. Flash is a thin flap of extra molding material that appears at the edges of the part, often in ejector pin locations or parting lines. It is usually a minor defect and can be easily trimmed off from the final product, but it could indicate insufficient pressure in the mold cavity. The best way to prevent flash is to increase injection pressure and nozzle temperature. Ventilation can also help if the injection mold is designed correctly. Flashing Flash is excess plastic that escapes the mold during the injection molding process. It can get out through ejector pin locations, the parting lines, or anywhere else that doesn’t properly seal. It can also occur because of improper clamping pressure or sprue bushing dimensions that are not appropriately adjusted for the application. Sink marks are visual depressions or indentations that appear on the surface of a finished molded product. Varying cooling rates can cause them, mismatched wall thicknesses between sections, or several other factors that require quality control to identify and correct. Professional mold manufacturers ensure the highest quality injection molded parts. It also ensures that a product is designed with optimal manufacturing efficiencies and optimized for the specific equipment used in production. This helps achieve the lowest unit costs without compromising quality or functionality. This is accomplished by analyzing the design and integrating it with a comprehensive injection molding process to deliver the quality and consistency your customers demand. Part Ejection Injection molding produces complex plastic components with high tensile strength. With proper design, these parts can meet or exceed the performance and durability of metal products. However, even the best injection-molded pieces can have issues that don’t necessarily stem from the manufacturing process. For example, if the parts aren’t the right size or shape, they can cause problems for customers when they try to use them. Finding these issues through quality control early can help companies avoid situations that could significantly impact their business. Quality control begins with comprehensive injection mold trials before production to prevent these issues. This testing ensures dimensional accuracy, uniform cooling channels, balanced filling, and accurate part ejection. Additionally, carefully polishing all the mold surfaces that come into contact with a molded part minimizes the risk of defects such as marks. Ejector pins – the “bouncers” of the injection molding world – can also leave scars, but experienced injection molders know how to position them to minimize this effect.
5.Are plastic injection mold manufacturers affected by international trade regulations?
Yes, plastic injection mold manufacturers can be affected by international trade regulations, as their business involves importing and exporting materials, equipment, and finished products. Some common ways in which trade regulations can impact plastic injection mold manufacturers include: 1. Tariffs and duties: Governments may impose tariffs and duties on imported and exported goods, including materials and equipment used in the manufacturing process. This can increase the cost of production for plastic injection mold manufacturers. 2. Trade agreements: Trade agreements between countries can also affect plastic injection mold manufacturers. For instance, free trade agreements may eliminate or reduce tariffs and other trade barriers, making it easier and cheaper to import materials and export finished products. 3. Export controls: Certain countries may have restrictions on certain types of technology or equipment that can be exported, which can impact the production process for plastic injection mold manufacturers. 4. Intellectual property protection: International trade regulations often include provisions for protecting intellectual property rights, which is important for plastic injection International trade policy impacts every mold builder, and policy shifts matter even more. Each decision potentially makes it easier or more difficult for a mold builder to export or to push back against unfair trade practices originating overseas. The U.S., Mexico, and Canada signed the NAFTA update, called USMCA, but the deal now faces scrutiny from the U.S. Congress to determine if they will approve it or not. The USMCA includes an increase in the percentage of North American content an automobile must contain to qualify for duty-free status. This item is an improvement that will keep more automotive parts manufacturing in the trade zone.

8.How does the material selection of plastic injection mold manufacturers affect the quality of finished products?
Injection molding mold manufacturing can be roughly divided into the following steps: I. Process analysis of injection molding mold plastic products Before designing the mold, the designer should fully analyze and study whether the plastic product conforms to the principle of injection molding, and needs to negotiate carefully with the product designer to reach a consensus. This includes necessary discussions on the geometric shape, dimensional accuracy and appearance requirements of the product, and try to avoid unnecessary complexity in the manufacture of injection molding molds. II. Injection molding mold structure design A set of high-quality molds requires not only good processing equipment and skilled mold manufacturing workers, but also a very important factor is to have a good injection molding mold design, especially for complex molds, the quality of the mold design accounts for the quality of the mold. more than 80%. An excellent mold design is: on the premise of meeting the requirements of customers, the processing cost is low, the processing difficulty is small, and the processing time is short. To do this, it is necessary not only to fully digest the requirements of the guests, but also to have an understanding of the injection molding machine, mold structure, processing technology and the processing capacity of the mold factory itself. Therefore, to improve the level of mold design, the following points should be made: 1. Understand every detail in the design of each mold, and understand the purpose of each part in the mold. 2. Refer to the previous similar designs when designing, and understand the situation during its injection molding mold processing and product production, and learn from the experience and lessons. 3. Learn more about the working process of the injection molding machine to deepen the relationship between the mold and the injection molding machine. 4. Go to the factory to understand the process of plastic injection molding products, and understand the characteristics and limitations of each type of processing. 5. Understand the test results and mold modification of the injection molding mold designed by yourself, and learn from it. 6. Try to use the more successful mold structure in the design. 7. Learn more about the influence of mold entering water on products. 8. Study some special mold structures and understand the latest mold technology. III. Determine injection molding mold material and select standard parts In the selection of mold materials, in addition to considering the accuracy and quality of the product, it is also necessary to give the correct choice in combination with the actual ability of the mold factory's processing and heat treatment. In addition, in order to shorten the manufacturing cycle, the existing standard parts are used as much as possible. IV. Parts processing and injection molding mold assembly In addition to giving the best structure and reasonable tolerance in the design, the precision of the mold is very important for the machining of parts and the assembly of the mold. Therefore, the selection of processing accuracy and processing method occupies an absolutely dominant position in the manufacture of injection molding mold. V. Injection molding mold A set of molds is only 70% to 80% of the entire manufacturing process from the start of design to the completion of assembly. For the error caused by the inconsistency between the predetermined shrinkage and the actual shrinkage, whether the demolding is successful or not, how is the cooling effect, especially the influence of the size, position and shape of the gate on the accuracy and appearance of the product, it must be tested by mold trial. Therefore, mold test is an indispensable step to check whether the injection molding mold is qualified and choose the best molding process.
9.What different types of molds can plastic injection mold manufacturers produce?
Injection molding is a manufacturing process used for the mass production of identical plastic parts. It’s a method of plastic injection where molten plastic is inserted into a mold to produce a part in the shape of the mold cavity, creating a physical representation of modeled plastic parts. Plastic injection molding has been around since the late 19th century and continues to be popular. If you look around, injection molded parts are everywhere, from the keys on your keyboard to the dashboard of your car to your X-Wing LEGO set. The plastic injection molding process is commonly used when large amounts of parts are needed quickly, when piece prices need to remain low, and when all parts need to be identical in size and other metrics. The main benefit of this process is its cost-effectiveness; sometimes it costs just cents per part for parts at scale. “At scale” typically refers to volumes ranging from thousands to hundreds of thousands of parts. However, it also is one of the most repeatable manufacturing processes, and it also has the highest variety of materials, colors, and cosmetics when compared to CNC machining or even 3D printing.
10.What is the basic process of manufacturing plastic injection mold manufacturers?
The mold manufacturing process for injection molding is referred to as mold tooling. Many molding shops offer mold tooling and design as a service on top of full-production injection molding. The majority of these molds are made of steel, but they can also be manufactured from aluminum. Mold tooling can be an intricate challenge as each mold is made up of many different parts. In this article, we will explain the mold manufacturing process and the exacting details needed to complete the perfect mold. Note: The molds/injection molding process mentioned in this article will reference book molds on a vertical injection molding machine. Structure of the Mold Mold Base: A mold base is made up of two or more metal plates. These are called clamp plates and hold all of the internal aspects of the mold in between them. The bottom clamp plate rests on the insert molding machine table and contains support pillars for the ejector plate. The top plate is what the machine’s nozzle will press down on to receive the plastic resin. Ejector Plate: The ejector plate is a moving part that assists in lifting the molded product out of the cavity. The plate itself has pins connected to it that fit through the rest of the mold and gently push the part up when it is finished. The plate keeps the pins together so they lift all at the same time. The ejector plate gets pushed up by the press knockouts attached to the machine. Ejector Retainer Plate: This plate is a relatively thin sheet of metal that fits over the ejector plate. The retainer has holes for each injector pin and acts as a support for them. “B” Plate: The “B” plate supports the mold cavity/core in place and is what the top half (“A” plate) of the mold closes on. The “B” plate is the final piece to the “B” half of the mold, which is sometimes referred to as the “live half” as it contains the ejector system (everything mentioned above). “A” Plate: The “A” plate, along with the “A” half does not contain any moving sections. This is the top section of the mold that closes on top of the “B” half and receives the plastic resin from the machine. Mold Cavity: The cavity is filled with the plastic resin that forms the final exterior shape of the part. The cavity can be placed in the “B” plate only, but most commonly is found in both the “B” and “A” plate. For insert molding, the “B” cavity is typically the side where the inserts will be placed to be over-molded. Mold Core: The mold core is what forms the interior of the final part. Similar to the cavity, the core can be found on either plate. Sometimes the complexity of a part (ex: medical injection molding products) requires a loose core insert. Inserts are removed from the mold at the end of each cycle and the part is then taken off the insert. Note: To help differentiate between the two, the cavity is always being filled with the resin, while the resin forms around the core.

21.Multi station and multi chamber mold design for plastic injection mold manufacturers
If you need to produce plastic parts, there’s a good chance you’ll end up using injection molding. Since this precise manufacturing process is a cost-effective way to produce medium and high volumes of identical plastic parts, it’s often a better choice than production methods like CNC machining or urethane casting. What is multi-cavity injection molding? Multi-cavity injection molding is a form of injection molding that involves molding two or more identical parts per cycle. Multi-cavity molds can contain anywhere between two and 164 cavities, and they typically increase in increments (2, 4, 8, 16, 24, 32, etc.). Stack molds — molds containing a mirror image of the tooling making the parts — are classified as multi-cavity molds because they ultimately produce identical parts. However, family molds — molds that produce multiple parts that are similar in size or appearance but not identical — cannot be classified as multi-cavity molds. Companies use multi-cavity injection molds for many different products in various industries including consumer goods, medical, and automotive. Product teams often start with a single-cavity mold to validate their design before shifting to a multi-cavity injection mold. Single-cavity molds are less expensive and quicker to produce. However, in some cases, it makes more sense to use a multi-cavity mold from the start. Manufacturing the same large volume of parts with a single-cavity mold rather than a multi-cavity mold means more cycles, more machine time, and higher costs. Multi-cavity molds will enable you to create more parts in less time and at a lower cost per part. The pros and cons of multi-cavity injection molding Multi-cavity injection molds use cycle times more efficiently, so you can produce more parts per hour. This increase in production efficiency makes it possible to fulfill high consumer demand faster. Despite the high initial costs associated with multi-cavity molds, they can also help you lower your cost per part and save money on high-volume production runs. Different types of runner technologies are used when designing single-cavity and even multi-cavity molds. Cold runners are typically used in prototype tooling to reduce initial investment. However, this increases material waste and there is a cost involved in re-grinding the excess material back into the process or disposing of it. Hot-runner technologies are typically used in proven-out designs to reduce material waste per cycle. Most multi-cavity molds use such technologies. However, multi-cavity injection molding also has its drawbacks, starting with the cost of creating the mold itself. Multi-cavity molds require more upfront investments than single-cavity molds because they take more material, energy, time, and labor to produce. If you have a limited budget or are planning to manufacture parts at lower volumes, using a single-cavity mold might be more practical. The pros and cons of multi-cavity injection molding Using a mold with multiple cavities as opposed to one offers several advantages. Multi-cavity injection molds use cycle times more efficiently, so you can produce more parts per hour. This increase in production efficiency makes it possible to fulfill high consumer demand faster. Despite the high initial costs associated with multi-cavity molds, they can also help you lower your cost per part and save money on high-volume production runs.
22.Preventive maintenance plan for equipment by plastic injection mold manufacturers
First, the purpose: So that equipment can maintain the best performance status and extend the service life, to ensure the normal production. Two. Scope of application: For mold maintenance and repair. Three. Regular inspection, maintenance: Need to be repaired by the mold, the upper and lower mold staff for regular maintenance and inspection. 1. Daily routine inspection and maintenance: 1.1 Whether the mold in operation is in the normal state a. Whether there is low-voltage mode-locked protection; b. Activities such as guide column, mandrel, line wear and tear, lubrication is good? Requires at least 12 hours to add an oil, the special structure to increase the number of refueling. c. The mold of the fixed template of the screw and the clamping clamp is loose; 1.2 production of normal conditions: check whether the product defects and mold; 1.3 under the machine to conduct a comprehensive inspection of the mold and anti-rust treatment: wipe dry cavity, core, the top of the body and the location and other parts of the water and spray mold rust or smear butter. 1.4 under the machine after the mold to be placed in the designated location and make a record: (1) mold status: intact or to be repaired. (2) when the mold when the rust treatment. 2. Quarterly check: Mainly on the placement of more than two months did not use the mold to clean up maintenance. 2.1 open the mold, check the internal anti-rust effect, there are abnormal circumstances, to be re-rust treatment. Long-term use of the mold to be coated with butter. 2.2 put it back in place and make a record. Four. Maintenance Note: 1. Non-professional maintenance personnel or without professional maintenance personnel to allow, not self-mold repair. 2. The production process of a small fault, transfer personnel can be resolved according to the situation. Such as: 2.1 into the plastic mouth sticky mold: the application of copper needle at the feed mouth at the knock, can not be used steel and other hard objects beat the mold. 2.2 cavity slightly die marks, according to the cavity of the finish to select the polishing material.There are not used sandpaper and other polishing materials, generally dipped in diamonds with diamond brush or diamond paste, by the professional maintenance staff to complete. 2.3 product sticky mold: generally covered with hot plastic products and the top of the site, to be cooled after the top out. Do not damage the mold surface with fire. 3. Professional maintenance mold, not free to change the structure, need to change the structure subject to the consent of the quality engineering department before proceeding. 4. To ensure the quality of maintenance, select the appropriate equipment, materials, tools and methods to solve the problem, the fastest speed to complete.
23.What design software do plastic injection mold manufacturers need?
Design and engineering is essential to building a better and more cost-effective mold with shorter leadtimes. A variety of software is available to help overcome the daily challenges faced with data, quoting, designing and programming—including computer-aided design (CAD), computer-aided manufacturing (CAM) and data management software. CAM is used to generate machining programs corresponding to part designs; CAD is used for detailed engineering of 3-D models and/or 2-D drawings.
24.How can plastic injection mold manufacturers extend the lifespan of their molds?
Tool life is key to a company’s bottom line and profitability. With the design and building stages complete, it is time to set the mold in the press and develop a process. Here are key press settings and essential preventative maintenance steps to improve mold life. Verify that you are using adequate tonnage for each mold. If an operator uses too little tonnage, the injection pressure can exceed the tonnage requirements and blow open the mold. If an operator uses excessive tonnage, the machine will apply excessive compression on parting lines, vent areas and mold components, damaging the tool. To avoid these situations, use the following formula to determine the proper tonnage for each mold: Cavity Area = Length x Width of mold face (in/2) Parts Area (Pa) = Cavity Area × # of Cavities Tonnage (T) = Parts Area × *(T) 3 tons/in2 (Note: thin-walled or high viscosity applications may require up to (T)5 tons/in2) Set up a low-pressure close (LPC) on the press to protect the mold. Set the high-pressure lock-up position no higher than 0.05 above the actual mold touch position. Also cycle the mold to reduce LPC pressure until the mold does not lock up. Pressure rises slowly, allowing just enough pressure for the mold to transition from low-pressure to high-pressure lock up. Also, set the mold close timer to 0.5 secs above the actual mold close time requirement. For example, if the actual mold close time is 0.76 secs, set the mold close timer at 1.26 seconds. Limit core pressures and speeds to the application’s requirements. Keep in mind that pressure can limit speed, but speed does not affect pressure set points. Fire cores based on position and not time to prevent crash conditions. Core operation affects cycle speed. Closely monitor core operation to identify signs that components are setting or pulling erratically. Clamp speeds are definite drivers of cycle time, but faster speeds are not better, as they can cause tool wear or damage. Monitor close fast speeds for signs of lunging that can cause mold drop and potential pin and component misalignment. Ensure the transition from close fast to close slow is smooth and that the close slow condition occurs just before component/pin match up. Ensure the transition between mold breakaway and mold open fast is also smooth, with the open fast segment occurring after all of the components have cleared the pins. Incorrect set points can endanger mold life through over-stroking or improper part ejection that causes parts to close up between mold halves. Base forward positions on the required amount of separation to properly remove parts from the mold. Over-stroking causes excessive strain on ejector pins and lifters. Part extraction should never require bottoming out the ejector plate. To reduce stress on ejection components, ensure pressure set points only use the required amount. Increased mold temperatures can adversely affect mold life, so limit mold temperatures to minimum requirements for acceptable part aesthetics. Also, ensure that mold half temperatures do not exceed a 20ºF variance between the stationary and movable halves. Temperatures above this scope cause improper heat soak conditions and poor tool mating conditions that damage the tool. Mark circuits and supply and return requirements clearly to prevent incorrect mold installation. Always inspect, clean and grease molds in production environments a minimum of once per shift. Watch for signs of wear, such as galling, parting line wear, burrs and metal shavings. Develop a regular preventative maintenance schedule, keep mold service records and review repetitive service/repair events to establish preventative maintenance frequencies that will help reduce unplanned service events. Verify that slide slots are greased and that slides are functioning properly. Watch for signs of detent failure and loose gibs. Verify that slide positions are correct as you exit the mold after every cleaning and inspection. Use rust preventative when a mold will not be used for more than 6 hours, and coat textured and polished areas thoroughly to prevent rust damage. The difference between the success or failure of a company’s tooling approach hinges upon its setup, implementation, and maintenance procedures covered in this checklist.
