How to save mold repair cost from mould manufacturing countries
The world’s major mold manufacturing countries, including the Asian region: Japan, South Korea and mainland China, as well as the United States & Germany, this article will induce different countries in mold industry and comparative analysis of national competitiveness and the mold repiar cost from each countries.
Mold industrial status in different countries
Countries in the world’s major manufacturing and marketing area, China has the largest number of plastic mold companies, nearly seven times as state-owned enterprises, foreign-funded enterprises account to run the large-scale mold factory and employs approximately 600 ~ 700 people, Foxconn Hon Hai Group (Foxconn) employs nearly 6,00000 people before 2017, mold factory is between 150 to 300, Foxconn moved lots of capacity to indian since 2018, but seems they will come back to China again in 2024, let us wait and see.
Small mold factories about 50 people, other countries mold industry have much more small factories, Applications market, Japan, South Korea, the United States and Germany produce the largest proportion for automobile products, while China produces electronics and communications products and mold, but resently China made lots of larg automotive molds for the world companies as well.
In accordance with 2002 national research report, Japan, South Korea and Germany, mold is a strong quasi-surplus goods, the China mainland and the United States mold due to domestic demand in large markets and are unable to complete the supply of domestic firms and required by the import of mold in order to meet downstream market of products manufacturing, , import and export of the region are mostly in neighboring countries, while Japan exported more remarkable region in the U.S. mainly, but mainland China in recent years due to the rapid development of downstream industries, mainland China has been gradually turned to expanding market trends
Wage countries, according to 2002 white paper on the findings of the mold industry, Germany paid the highest salaries of technical staff for $ 12.13 ~ $ 19.28 per hour, the designer is $ 16.91 ~ $ 25.26, between Japan and the United States, the mold factory pay the lowest-paid technicians annual salary of only $ 732 ~ $ 5,853, the designer is only $ 2,927 ~ $ 5,853, China low wage costs have so great advantage
Analysis of national strengths and weaknesses
Technologically advanced countries such as Japan, the United States, Germany, for high-precision and complex nature of mold development, regardless of design capacity or manufacturing technology, have a leading position, but also have excellent R & D personnel practice. The Japanese mould maker emphasis on technically polished with the polishing process, the German mold manufacturers by enhancing mechanical processing and electrical discharge machining precision and efficiency begin to reduce the manual processing time. Market size regardless of value or domestic demand in Japan’s decline was most evident.
Operating costs are often faced with high wages, high benefits, so the downstream industries or mold makers to move production facilities to gradually close to the newly industrialized countries or technological backward countries, in order to reduce labour costs and enhance price competitiveness, but the trend is likely to cause technical invisible exodus worries, making themselves, even more, to be put in a large research and development costs in order to speed up the upgrading process technology and high-speed mechanical properties, widening the difference between each other. Taiwan, Korea and mainland China, South Korea and mainland China market in recent years.
the scale of production and demand are presented growing trend, particularly in mainland China mould industry is the rapid development of national brand name manufacturers stationed in production equipment, invisible mold development to enhance the strength and design capabilities. Costs, mainland China and South Korea because it has a relatively low labour cost advantage, and therefore the selling price for the mold, often take low-cost marketing to market, and thus poor global economic situation, the successful buyer to grab the market favour, the most obvious example of the gains in export value.
After many years since 2022, China can make hgih precision mold with competitive price, since 2010, most of companies were buying their molds from China, high quality and lower cost China molds are popular to the worlds, once you have your mold in China for production, the injection mold repair and maitain cost are nearly free, unless you change your design.
The conclusion On the whole, as countries mould industry, and many types of small business operations, therefore, operating on a regular fund-raising is difficulty, in the absence of government policy support and tax incentives in the formation of mold industry will go it alone with the situation alone, the only way is increasing the additional value of products in order to get rid of low-cost competition.
Finally, if you have a project that need plastic molding parts, to save your cost, find China mold maker will be one of the best options, Contact us today for your project, we will do your plastic injection mold repair and maitainance for free.
I am trying to find out how large manufacturing companies grind precision core pins. As a plastic mold maker, I am aware of the manual methods using a surface grinder and Harig type spin fixture and am also familiar with the Ded-Tru machine.
However, these methods are exceedingly slow, albeit quite precise. There just has to be some kind of OD grinder, tool grinder, centerless grinder or special CNC tool grinder that can grind complex mold core pins accurately and with an excellent finish.
But in today, normally the mold maker is not making any pins or insert pins by themselves, you can find some precision components company who specializes in making high precision components, like insert pins and some small inserts, you only need to send them the 3D, 2D drawing and mark the tolerance for each dimension, then they will do the rest quickly and accurately.
But for some other mold components, you may have to do this by yourself.
Another common material for various injection mold components is a beryllium copper alloy also called Mold Max. It has excellent heat transfer qualities, can be polished and is also pre-hardened. All this combines to make it the material of choice for things such as core pins.
However, is beryllium copper/Mold Max safe?
In my experience is depending on which area of mold components you are using for? I made 64 cavities molds which the parts have some small ribs, the customer was a requirement with MoldMax for better cooling, as you know sixth four core inserts made by Mold Max, that is not cheap, but after the second time of mold trial the small ribs start to break, not only one or two but around 10 inserts had broken done, base on my experience on this material, for some small ribs it is not good option to use Beryllium copper, if some deep ribs but have much more space, then that will be better option to use this material, because you will get good cooling to save cycle time.
This covers the topic in detail and my conclusion is that it is basically depending on the part design, Is you have a plastic mold project that may need this service, you are welcome to send me your drawing, we will suggest you some good option for you to make choices this could be safer for your project.
High volume injection molding is a critical process in manufacturing large volumes of plastic parts in a short time. It’s a straightforward process involving two key steps: acquiring the mold and then using it to make parts. This systematic approach helps cut down the cycle time and ensures that the output is standardized and, hence, is cost-effective for large projects due to economies of scale.

Three Volumes of Injection Molding
Different plastic injection molding providers often focus on specific volume categories:
Small-Volume Plastic Injection Molding: These providers are most suitable for projects with less than 10,000 parts. They usually employ aluminum tooling for short time production runs. Small-volume specialists are great for; Small-volume specialists are great for:
Prototyping injection molding: Cheap and fast for determining the feasibility of designs, form, fit, and function, and for prototyping before production.
Low-volume injection molding production: It is a very efficient and economical process for applications such as specific medical devices that are not required to produce hundreds of thousands of parts.
Market testing and pilot production: Perfect for making a transition from short-run production to volume manufacturing.
Medium-Volume Plastic Injection Molding: These companies specialize in medium to high volume production of between 10,000 and 750,000 parts. They use aluminum or pre-hardened steel tooling, depending on the order size.
Large-Volume Plastic Injection Molding: These providers focus on orders over 750,000 parts and can manufacture hundreds of thousands of parts with precision and quality. They employ only the best hardened steel molds and incorporate modern technology, and they usually do not take orders below 750,000 parts. This category includes:
- High tolerance precision, low scrap loss, and low cost.
- Little post-production work is required because of the technology used and the quality of molds.
Considerations for Choosing Between Low and High-Volume Injection Molding
Choosing between low and high-volume injection molding depends on several factors that should be considered carefully:
Production Needs: If the production requirement is less than 75,000, then low-volume injection moulding is often the most suitable because of the cost advantage.
Design Complexity: In the case of special or prototype designs, low-cycle injection molding is useful in the economical testing and development of the tool.
Production Cost: When costs increase during production, prototyping, and automation can be advantageous to a business. High volume injection molding becomes more possible in such cases as it greatly cuts the cost of per unit production.
Set-Up Budget: It is possible to begin with low volume injection molding, especially if there is a limitation on the amount of capital to be invested in the molding process since high-volume molding calls for a huge investment at the initial stage. Also, high-volume processes using steel tools will result in long cycle times and high material costs.
Advantages of High-Volume Injection Molding:
- Cost-Effective Production: Flexible and fast, which reduces labor and material expenses.
- High-Production Output: Can manufacture many parts at once to address the variations in demand.
- Consistent Quality: This guarantees that the parts are accurate and similar, with very small variations and complex features.
- Versatility in Part Design: It can produce various designs and shapes and work with different geometries.
- Reduced Waste: Reduces the amount of scrap and waste since injection parameters are well controlled and the molds used are of high quality.
- Increased Production Efficiency: Very low level of manual intervention and is mostly operated through computer systems.
Disadvantages of High-Volume Injection Molding:
- High Initial Investment: This involves a high initial cost for mold design and construction.
- Long Lead Times: The creation of molds can take a long time since the design and production of molds require time.
- Limited Material Choices: Some plastic resins may not be ideal for high-volume manufacturing.
- Limited Design Flexibility: Accurate process that restricts the geometry of the part, especially for intricate shapes.
- High Maintenance and Repair Costs: Maintenance and repairs of molds are often costly and may require frequent replacements.
Material Types Used In High Volume Injection Molding
High volume injection molding requires careful consideration of the type of material to be used to get the best results. Polypropylene (PP) is the most popular type due to its low cost, high strength-to-weight ratio, and high impact resistance. It is used in the automotive, packaging, and consumer goods industries. On the other hand, Acrylonitrile Butadiene Styrene (ABS) has the properties of being tough, impact resistant and smooth finish used in toys, automotive parts and electronic devices.
Polycarbonate (PC) is highly valued for its ability to withstand impact, transparency, and heat stability, which makes it suitable for the automotive, aerospace, and electronics industries. Polyethylene (PE), which is flexible, hard, and chemically resistant, is used in packaging, plastic bags, and agricultural films because it is light and can be molded in many ways.
Polyethylene Terephthalate (PET) excels with its strength, transparency and barrier properties, making it suitable for use in beverage bottles, food packaging and protective packaging. Finally, Polystyrene (PS) is cheap, lightweight and insulating, which makes it ideal for use in disposable cups, packaging and insulation. Each of them meets certain requirements, which guarantees the quality of the final product in large-scale injection molding.
Machine Types Used for High volume Injection Molding
Injection molding machines are used in high-production processes, where the plastic material is injected into a mold to produce different parts.
Hydraulic Injection Molding Machines are machines that use hydraulic pressure to operate and are characterized by high production rates but slow cycle rates, thus appropriate for high production volume but low cycle time applications. Electric Injection Molding Machines, which are driven by electric servo motors are very accurate and fast and are suitable for applications in areas such as the production of medical equipment and electronics.
Hybrid injection molding machines are a combination of hydraulic and electric machines, which are efficient, fast and offer high production rates, thus suitable for high production requirements.
Two-Shot Injection Molding Machines are used to make parts of two different materials or two different colours and are suitable for making parts with high complexity.
Multi-Material Injection Molding Machines have multiple injection units for the processing of different materials at once to meet the requirements of parts with different properties such as strength, durability, and flexibility. Liquid Injection Molding Machines are specifically designed for producing LSR parts, and the parts are very accurate and strong, making them ideal for applications such as medical equipment and automotive parts. These machines are used to meet particular production needs and help achieve high-quality and fast high-volume molding.
Design Considerations For High Volume Injection Molding
Several factors need to be taken into account when designing a plastic part for high-volume injection molding.
First, the wall thickness should be uniform so that the cooling process will not be a problem and the part will not warp. Thin walls are suitable for mass production as they use less material and time as compared to thick-walled parts that provide extra strength where required.
This is also true in the size and shape of the part, as it determines the time taken in production. Shapes that are large or complex may take longer cycles or specialized equipment which increases the cost. The more complex the design, the more difficult it is to produce many items; therefore, geometric patterns are preferred. Draft angles should also be incorporated into the design to enable easy removal of the parts and to prevent problems such as cracking or deformation during production.
The location and size of gates are very important. Gates should be positioned so that they will not compromise the structure of the building and be of the right size so that they do not interfere with the flow of materials that are to be transported. Material selection should take into account the requirement of the part to be manufactured in terms of strength, durability, and flexibility.
Surface finish matters too. The surfaces of parts should be polished and should not contain any imperfections such as warping or sink marks. Some of the factors that help in attaining a smooth surface include proper gate placement, mold design, and the choice of material. Lastly, tolerance, which is the permissible deviation in the dimensions of the parts, should be given due consideration right from the design stage so that the parts can be manufactured accurately and with a high degree of precision.
Common defects In High Volume Injection molding
In high volume injection molding, there are several types of defects that may affect the quality of the end product. Sink marks are those marks which are formed due to the uneven distribution of material during the cooling process and can be avoided by redesigning the part and ensuring that the wall thickness is uniform. Distortion, which results in part distortion, can be prevented by regulating the temperature of the mold and by including features that reduce stress.
Flash excess material that protrudes from mold joints is caused by misalignment or lack of clamping force and can be avoided by correct alignment of the mold and sufficient clamping pressure. Short shots and incomplete filling of the mold cavity due to problems such as low injection pressure or blocked gates can be solved by adjusting the injection parameters and gate design.
Finally, weld lines, which are apparent signs of meeting flow fronts, can be avoided with proper design of the mold and injection parameters to ensure equal material distribution. These strategies assist in ensuring that the quality of the products produced by the high volume injection molding is high.
Tips To Maximize the Productivity of High-Volume Injection Molding
Problem-solving in high volume injection molding is crucial to ensure the quality of the end products. Here are some practical tips for addressing common issues:
Check Machine Settings: Start the problem-solving process by checking the injection molding machine parameters. Ensure that the temperature, pressure, and cycle time are correctly set depending on the material to be processed.
Address Material Flow Problems: Pay particular attention to any problems that may arise in the field of material flow. Defective settings of the machines or the presence of barriers in the flow of materials can also be a hindrance. Make sure that the material does not jam in the machine during the process.
Combat Warping and Shrinkage: Distortion and shrinkage are typical issues in large-volume injection molding because of non-uniform cooling. Reduce the cooling time depending on the material properties to prevent warping and shrinking of the part.
Prevent Air Traps: Air locks are formed when air is locked in the mold cavity, and this results to the formation of voids or bubbles. Make sure that there are no trapped air pockets in the mold so that they do not influence the final product.
Monitor the Process: Ensure that you monitor the whole injection molding process very closely. The following are some of the best practices that can be followed to ensure that the problems are detected early: This proactive approach enables one to prevent possible issues that may affect the quality of the products.
Conclusion
If you are still unsure of which molding process to use, you should consider seeking the help of a professional. However, to get the best results, it is imperative that the selected injection molding process is in sync with the production requirements. Any difference can lead to an interruption of the production process, and this, on its own, increases the cost greatly.
They may cause disruptions that hinder production, and this, in turn, has an impact on your ability to produce quality products at reasonable prices. This can, in the long run, affect your customer relations and their satisfaction levels.

Complex moulds: SINCERE TECH has a rich experience in difficult plastic mould and parts, complex moulds and is an expert in finding solutions to your issues. SINCERE TECH is a real specialist in difficult tooling. To give a classic example: many design companies create plastic products without thinking about mould construction. Then, when the designs are sent to toolmakers, it can be hard for them to make the exact parts (Difficult design, many sliders, many lifters, double injection with materials non-bonding well together, many details in awkward places…).
Most of the classic toolmakers will accept the parts and say that they are able to do it. And then, they will have problems with the plastic injection mould construction, the lead time will be extended and the quality of the tool will not be as expected. Often, these companies have to contact SINCERE TECH to help them to resolve their problems. If you are not sure about the complexity of your part, be sure about your mould maker’s professionalism. SINCERE TECH works closely with its customers in order to resolve any issues.
Thin Wall injection molding: it permits a precise, very accurate molding of plastics and gives better details to the product. This is the name referring to products with a wall thickness lower than 2mm. Usually, the flow is quick, permits a short cycle time and a cost-saving.
Hot runner mold: the special process of injection of plastics where the plastic is kept hot when going through cavities of the mould while the rest of the mould is getting cold to solidify the plastic part and create the molded part: this permits to save plastic material. This is mainly used for parts with medium or large sizes. We are used to working with all popular companies like Yudo, INCOE, Synventive, Husky, HRS… We also have the technology to make our own hot runner systems if the production of the parts (Molding) is made in-house. This again allows our customers to save costs.
Optical Lens Molding: precision molding for glass plastic. This is the technique to produce transparent plastic molded parts (For example Security cameras parts such as the dome cover or also phone frames).
Gas-assist Injection Molding: the plastic parts are gas-assisted molded which means that gas (Most often is nitrogen) is injected at the final stage of the part creation process. It permits to reduce the cycle time, the product weight, the risk of deformation and also the pressure tons injection needed. Moreover, it makes the part’s structure stronger with a better look.
LED/LCD frame molding: injection of plastics used for example to manufacture television screen monitors, computer back-light modules, GPS frames…
IMD, IMF, IML, IMR Molding: In-mold decoration. The decoration of the part is made inside the mould through a film. The film is printed before the molding with the designs wanted. It permits better productivity and extends the decoration’s lifetime. If the customer wants to change the design/decoration of the part, it is not necessary to make another mould but only to change the film. SINCERE TECH is experienced with In-mould forming, in-mold-labeling, and in-mold by roller.
Overmolding: this technique permits to join several components together with a thermoplastic material. This reduces assembly and labor costs. Because the parts are made together, this allows less risk of improper termination or misalignment and increases the design flexibility. Moreover, thermoplastic provides better resistance to vibration or shocks. This technique permits to increase resistance, reduce costs and weights.
Insert Molding: this is a technique where a small part (Stamping part, optical part…) is added or inserted to the Injection molded part.
Two-Shot Molding: 2 independent injection units using 2 different materials and/or colors. The first material is injected; then, the mould rotates and the second material is injected to make 1 part. It permits a 2-colour-molding or also called double injection, 2 shot molding, two-shot injection, overmolding, 2K injection, two colour injection, bi-injection, dual shot molding or multi-component molding.
CNC Technology. CNC is an abbreviation for Computer Numerical Control. This is a machine extremely accurately controlled by computer programs permitting a CAM (Computer-aided Manufacturing) through a CAD (Computer-Aided Design). Any plastic injection tool manufacturer uses it but the value-added of SINCERE TECH is the experience, professionalism, and training of the staff.
FMMS Molding or can be called RHCM (Rapid Heat Cycle Molding): excellence surface appearance: permits to take off the welding line. This process is integrated into the molding to save time. It is used for example for clear plastic parts.
US Welding: Ultrasonic Welding: process to weld/ join/ assemble plastic parts thanks to ultra-sounds.
Silk-Screen Printing: this is to print logos or designs on parts.
Dip-Coating: this is the process of putting the component inside a liquid solution to apply a thin film on it. It permits to manage, change the hardness, the strength of the part by protecting it and expanding the lifetime of the product. Then, the excess liquid has to be drained and evaporation of the solvent is done to create the thin layer.
Laser Etching: this process is made for cutting a shape, a pattern, an image on the plastic part. It is also called laser graving.
Sputtering coating: this is the process of creating a very thin layer of conducting material on the component. It is also called Plasma Enhanced Chemical Vapor Deposition (PECVD) and can be done with most metals like aluminum, stainless steel, copper…
EMI shielding: protect parts from electromagnetic interferences. It is used to protect electrical signals from the outside world. For instance, we use it with marine radars for Garmin.
Waterproof technology: SINCERE TECH has the experience to make water-resistant parts and is able to ensure in-house tests thanks to the IP68 tests.
