6 Ways to Reduce Your Injection Molding Costs
6 Ways to Reduce Your Injection Molding Costs
Injection moulding is a manufacturing process used universally to manufacture various everyday goods. The majority of mass-produced products contain plastic injection moulded components including furniture fixings, plastic cutlery, CCTV cameras, games consoles, toasters, and vacuum cleaners.
How much does plastic injection moulding cost?
How to reduce the cost of mold?
The price of injection moulding varies with every project. Due to the initial upfront cost of the mould and tooling, the greater the number of parts being produced, the lower the overall unit costs. This is because tooling costs can be absorbed across more parts. Mass-produced parts often use injection moulding as it is the most economical and timely way to produce plastic parts at high volumes.
From a narrow point of view, this answer is good, but if it is only this, then in addition to cutting corners and tax evasion, is there any way to control or reduce costs?
Ways to reduce costs in injection moulding
There are several main cost drivers with injection moulding projects. Consequently, there are methods and best practices you can apply to reduce the costs of injection moulding for a more cost-effective solution whilst still providing excellent results.
Larger production runs can be beneficial in that they can benefit from economies of scale which reduce unit costs. However, depending on budgets and requirements, larger production runs may not be suitable as they often result in surplus stock and waste. If you are looking for further ways to reduce costs in your injection moulding project, this guide analyses injection moulding costs and offers solutions and ways to save money throughout the injection moulding process.
Injection moulding costs are determined by various factors, including:
Optimize Part Design: The design of the part being molded has a significant impact on the cost of the injection molding process. A well-designed part can reduce the number of parts required to make the product, which in turn reduces the cost of materials and production time.

Find a good supplier of injection molding? Yes, We are
The United States and European companies can produce perfect products, high precision injection molded parts also. Why set to purchase goal finally in China. This is a very interesting question, the price is a major factor, but now Southeast Asia or Mexico is much cheaper, so the system of integrated suppliers is the key issue today. We will explore how the real system integration suppliers. How to choose an injection molding supplier, especially you are a beginner to buy mould and plastic injection molding part from china company, we can find the following:
The principal advantage of injection molding is the ability to scale production en masse. Once the initial costs have been paid the price per unit during injection molded manufacturing is extremely low. The price also tends to drop drastically as more parts are produced.
As the integrated system of Chinese injection suppliers is committed to high quality and punctual delivery, while maintaining acceptable market prices, any kind of injection molding factory out of the market, will eventually be eliminated by the market.
Our German clients MERKLE who is a robotic end arm leader once talked about one of his bad memories with me, when he started the business with a Chinese injection molding company dealing, simply promise company must not ideal supplier, China will go a long way to instill the enterprise executive ability, can reliable OEM suppliers.
The injection molding China suppliers, production of the full set of solutions. I know my team to do due diligence to ensure customer satisfaction every day. This is we as a business to make money (after all, this is any commercial purpose). But if customers are satisfied with our products, and services he/they will be back to do business with us and recommend to other companies.
Good Supplier Good Assistant – Precision injection molding characteristics
Precision injection molding is generally referred to as the precision of forming parts and surface quality is demanding high technology. Some people think that precision injection is the size of plastic parts to achieve the accuracy of 0.01 ~ 0.001 mm injection molding process.

Mold Polishing Tips For Injection Molds
Mirror polish injection molds
What is mirror polishing?
Mirror polish injection molds refer to molds that have a highly reflective and smooth surface finish, similar to a mirror. This is achieved through a polishing process that removes any surface imperfections and creates a high-gloss finish.
Mirror polish injection molds are often used in applications where the final product requires a high level of clarity, such as in medical devices, optical lenses, and consumer electronics. The mirror-like finish helps to reduce the amount of light scattering and distortion, resulting in a clearer and more precise image.
The polishing process for injection molds is typically done using a series of abrasive compounds and polishing tools, starting with a coarse grit and gradually moving to finer grits until the desired level of mirror finish is achieved. The process can be time-consuming and requires a high level of skill and expertise to achieve the desired result.
Overall, mirror polish injection molds are a valuable tool for producing high-quality products that require a clear and precise finish.
Mold Polishing Tips For Injection Molds:
① Surface after the rough polishing process by milling
EDM, grinding, etc. You can choose the speed at 35 000-40 000 rpm rotating surface polishing machine or ultrasonic grinding machine for polishing. Commonly used methods using diameter Φ3mm, WA # 400 wheel removing layers of white sparks. Then hand Whetstone grinding, strip Whetstone plus kerosene as a lubricant or coolant. The general order of use is # 180 to # 240 to # 320 ~ # 400 ~ # 600 ~ # 800 to # 1000. Whetstone polishing method. Which is the most important job a difficult job processed according to different specifications? And an angle of approximately 70 degrees a balanced cross lapping position? Ideally from a range of about 40 mm to 70 mm. Whetstone jobs will vary according to the material processed. Many mold manufacturers in order to save time and choose from # 400 to start.
② Semi-fine polishing semi-fine polishing mainly used sandpaper and kerosene.
After Whetstone's job is job sandpaper, sandpaper when the job. Pays attention to die Jen rounded edges, rounded corners, and orange peel generation. So try to make the finest Whetstone flow processing. Sandpaper polishing focus. Sandpaper with a hard stick like a stone like a job for about 70-degree angle to cross grinding. Polishing sandpaper side number about 10 times to 15 times. If the grinding time is too long, the grinding force of sandpaper will reduce. Which would lead to the machined surface uneven phenomenon? Which is also produced one of the reasons orange peel?
When jobs are generally used bamboo sandpaper grinding. Low stretch material actually used a small stick or rod hardness of about 45-degree angle grinding is the most ideal. The polished surface cannot be used as a rubber or a material with high elasticity. And cannot be polished with a 45-degree angle may be an acute angle shape. Numeral sandpaper as follows: # 220 ~ # 320 ~ # 400 ~ # 600 ~ # 800 ~ # 1000 to # 1200 to # 1500. Actually, # 1500 sandpaper only suitable for hardened tool steel (52HRC above) does not apply to pre-hardened steel. This may lead to pre-hardened steel surface burns.
③ Fine polishing diamond polishing paste mainly used.
If the powder or mixture of diamond abrasive grinding wheel pastes for polishing a polishing cloth. Then the order of the normal polishing 9μm (# 1800) ~ 6μm (# 3000) ~ 3μm (# 8000). 9μm diamond polishing paste and polishing cloth wheel can be used to remove the # 1200 and # 1500, leaving hair like sandpaper grinding marks. Then with sticky carpets and diamond polishing paste for polishing. The order of 1μm (# 14000) ~ 1 / 2μm (# 60000) ~ 1 / 4μm (# 100000).
Accuracy requirements in 1μm above (including 1μm) polishing process in the mold processing workshop in a clean polished interior can be carried out. If a more precise polishing an absolute necessity to clean the space. Dust, smoke, dandruff. And saliva Mo is likely to be scrapped after a few hours of work to get a high-precision polishing surface.
Cn-moulding is a reusable china injection mold company. We focus on high glossy mold manufacturing. One strong point of us is polished mold mirror and glossy, with short cycle time and competitive price.

plastic parts flash solution
Plastic Parts Flash Solution: A Comprehensive Guide
Plastic parts flash is a common problem in the injection molding process. It refers to the excess material that protrudes from the molded part due to the presence of gaps or misalignment between the mold halves. This flash not only affects the aesthetics of the finished product but also compromises its functionality. Fortunately, there are several solutions to this problem, and in this blog post, we will discuss them in detail.
Optimize the Mold Design
The first step in preventing plastic parts flash is to optimize the mold design. This includes ensuring that the mold halves are aligned correctly and that there are no gaps or misalignments. The use of high-quality materials and precision machining techniques can also help to reduce the occurrence of flash.
Adjust the Injection Molding Process
Another solution to plastic parts flash is to adjust the injection molding process. This includes optimizing the injection speed, pressure, and temperature to ensure that the plastic material flows smoothly and fills all the cavities in the mold. The use of injection molding simulation software can help to identify potential issues in the process and optimize it accordingly.
Use Mold Release Agents
Mold release agents can also be used to prevent plastic parts flash. These agents are applied to the mold surface before injection molding, and they help to reduce friction between the mold and the plastic material. This, in turn, reduces the occurrence of flash and improves the overall quality of the finished product.
Implement Post-Molding Operations
Post-molding operations such as trimming, sanding, and polishing can also be used to remove plastic parts flash. These operations are carried out after the injection molding process and involve removing the excess material using specialized tools and techniques. However, this solution is time-consuming and can increase the overall production cost.
Use Automated Deflashing Equipment
Automated deflashing equipment is another solution to plastic parts flash. This equipment uses specialized tools and techniques to remove the excess material from the molded parts automatically. This solution is faster and more efficient than manual trimming and can significantly reduce the overall production cost.
Reference
1, Should be paid attention to, for the mold and excessive clamping pressure also can produce flash, parting surface, between the clip into the foreign body damage both mold and produces the burrs.
2, Injection mold material often use S50C JJS (Japan standard domestic 50 # steel) using HRC30 hardening of the special steel in advance, it is difficult to produce burrs in parting surface
Conclusion
Plastic parts flash is a common problem in the injection molding process, but it can be prevented using various solutions such as optimizing the mold design, adjusting the injection molding process, using mold release agents, implementing post-molding operations, and using automated deflashing equipment. Each solution has its advantages and disadvantages, and the choice of solution will depend on the specific requirements of the product and the production process. By implementing these solutions, manufacturers can improve the quality of their products and increase their competitiveness in the market.

Injection mold cooling
Design and cooling system
The plastic injection mold cavity is cooled by a cooling channel on a fixed form. The injection mold core is provided with cooling water holes inside, which are separated by a water separator in the middle. The cooling water enters by the cooling water holes on the supporting plate. And rises up to the upper part of the core along one side of the water separator plate, turns over the water separator, and flows to the other side. And then flows back to the cooling water holes on the support plate. The second core is then cooled and the injection mold is finally discharged from the cooling water hole on the support plate.
The cooling system use value
The cooling system of plastic injection mold directly influences the production efficiency and quality of plastic parts. Cooling effect of the cooling system determines the cooling time. While the cooling time of plastic injection mold takes up about 2/3 of the entire injection mold cycle. A complete cooling system can significantly reduce the cooling time, thus improving the efficiency of injection mold production.
Cooling system layout
The deformation and internal residual thermal stress of the plastic parts are often caused by uneven cooling. By using CAE technology, the economic cooling time, reasonable size, and arrangement of injection mold cooling pipe can be obtained. So that the plastic parts can be cooled as uniformly as possible. And the cooling system for plastic injection molds is designed to maintain proper and efficient cooling of molds. The cooling hole should be of standard size for easy processing and assembly. When designing the cooling system, the mold designer must determine the following design parameters according to the meat thickness and volume of the plastic part. The position and size of the cooling channel, the length of the channel. The type of channel, the configuration, and the connection of the channel. And the flow rate and heat transfer properties of the coolant.
Actual Combat Mold Maker
A lot of our injection experience is in medicine machines, so stretch-proof is visible and to be avoided. We formed a medical mechanical shell and internal structure. So we have high antioxidant materials, with high precision parts. We measured part deformation with a 3d coordinate measuring instrument. We have also increased the forming time of mould, mixed with injection molding additives.
Typically we set the injection mold temperature near the critical point of the plastic. After the mold cooling time is long enough, and then pull the part out of slow cooling air.
Naturally, these were high quality and accurate. My key is to let the resin into the injection mold quickly, slow cooling down all parts of the critical point. And then slowly cooled to room temperature. Of course, there is a way to inject the injection mold preheating. And then cooled slowly and uniformly to accelerate this will be an asset.
Air Cooling use in Injection Mold
In recent years, our company try other ideas
Through the air cooling switch settings, although able to solve the problem, but because only injected a large amount of high-pressure air into the storage tank in order to get good results, the development cost is too high, is not a good way.
We did not give up, professional engineers began a new attempt respectively we use customers are widely used in medical products in the ABS and NYLON material into the warm water for 20 minutes, 0 degrees after immersion in cold water, so that through the solution temperature so as to keep the temperature at 70’C.
The critical temperature we set for the best cooling index. Put into the 100 products of each batch of a tank for cooling, completely solve the heat caused by the shrinkage and warpage. Even if it contains talcum powder, glass fiber is also applicable in this way.
Through a 100 mm diameter cylindrical shell, the medical project length of 1 meter, efforts to control temperature changes of each process.
Whether it is injected into the mold cavity from the material or product in ice water cooling time. We always grasp the critical point for 70 degrees of success is not only a result, and the profit is guaranteed. Any questions about technology products, according to the product, mold manufacturing, injection molding to find solutions.

Injection Molding Companies Do Not Have Rankings
When we choose injection molding factories, many people rely on search engine rankings to make decisions. Each company has different characteristics, different specialties, and different customer groups. This makes it impossible to do a professional ranking of these companies.
The injection molding is which involves creating plastic parts by injecting molten plastic into a mold. While there are many injection molding companies out there, it is important to note that there is no official ranking system for these companies.
Unlike some industries, such as the automotive industry, where there are clear rankings of the top companies based on factors such as revenue and market share, the injection molding industry does not have any sort of official ranking system. This is because there are many different factors that can influence the success of an injection molding company, and these factors can vary greatly from company to company.
One factor that can influence the success of an injection molding company is the quality of their products. Companies that produce high-quality parts that meet or exceed customer expectations are likely to be more successful than those that produce lower-quality parts. However, quality is not the only factor that determines success in the injection molding industry.
Another important factor is efficiency. Companies that are able to produce parts quickly and at a low cost are likely to be more successful than those that struggle with efficiency. This is because efficient companies are able to offer lower prices to their customers, which can give them a competitive edge in the marketplace.
Customer service is also an important factor in the success of an injection molding company. Companies that are able to provide excellent customer service and support are likely to have more satisfied customers, which can lead to repeat business and positive word-of-mouth referrals.
Finally, innovation is another key factor in the success of an injection molding company. Companies that are able to stay ahead of the curve in terms of technology and manufacturing processes are likely to be more successful than those that fall behind. This is because innovative companies are able to offer new and improved products and services that meet the changing needs of their customers.
In conclusion, while there is no official ranking system for injection molding companies, there are many different factors that can influence the success of these companies. Quality, efficiency, customer service, and innovation are just a few of the factors that can make a difference in the competitive world of injection molding. As such, it is important for companies in this industry to focus on these factors in order to stay competitive and successful.

China prototype, Chinese prototype
Rapid prototyping and model making is an essential step in the product design and development process, whether to demonstrate form, function, or manufacturability. It will ensure clients, designers, and all development partners have a clear understanding of the design intent. Can effectively contribute to design validation. Print and screen-based presentations are effective tools. But only a prototype that you can both see and touch can ensure everyone sees the same thing. And so avoid the misunderstandings all too often seen in product development. Advantages of Chinese product development and manufacture extend to a well-established base of local prototyping expertise, matching services. And quality offered by western prototyping firms.

POM-plastic material
As a professional plastic injection molding company in china. Cn-moulding is able to provide different plastic injection molded parts. Such as insert molding, double-color molding, multi-cavity plastic molding, and hot runner plastic moulding with Polyacetal/Acetal material.
Polyacetal (POM) POM called “Race of steel”, is a crystalline plastic, main properties are as follows:
1, POM plastic material is white plastic and shiny.
2, Has good mechanical properties, hardness, high stiffness, good impact resistance, and excellent abrasion resistance and self-lubricating properties.
3, Good resistance to organic solvents, stable performance.
4, After forming size is relatively stable, and less affected by humidity.
POM molding process to understand
1, POM plastic material small (smaller absorption rate <0.5%) moisture, generally does not dry before molding or short dry.
2, Molding temperature range is narrow, with poor thermal stability above 250 ℃ decompositions of formaldehyde
monomer (melt darken). It alone raises the temperature to improve liquidity and has no harmful effects. In normal beer, the
plastic feeding tube should adopt a lower temperature. And a shorter residence time and increased injection
pressure can improve mobility. The quality of the product surface melt (melt flow rate of shear sensitive) temperature
parameters. Before feeding tube 190-210 ℃, the feeding tube 180-205 ℃, after feeding tube 150-175 ℃ pressure parameters.
The injection pressure is about 100Mpa, back pressure 0.5Mpa.
3, Mold temperature control at 80-100 ℃ is appropriate (usually run hot oil).
4. POM cooling shrinkage large (2 to 2.5%) prone beer plastic “shrink”, must be used to extend the holding
time to feeding.
Process conditions for injection molding:
1， Drying: the moisture absorption of the resin itself is very small, so it is not necessary to dry. But if the water content during molding is greater than 0.1%. It needs to be dried, which is also conducive to avoiding the phenomenon of mold scale. But for some filling grades. Such as carbon fiber filling, and conductive grades. It must be dried, in drying conditions of 80-90℃, 3~4 hours.
2， Recycling: recycled materials can be used. Even if 100% of recycled materials are used 10 times. Their physical properties basically will not change, but the color will change. In principle are 25-30% recycled materials and 75-70% new materials mixed-use.
3， Thermal stability: stay at the temperature of 210℃ for 60 minutes before molding. The tensile strength of the molded product hardly changes. It has good thermal stability.
4， Injection machine: general injection molding, projection area x40-60mpa of mold-closing force > moulds.
5， Cylinder capacity: the product weight is generally 40-80% of the cylinder capacity.
6， Nozzle and latching system: open nozzle is available, but to prevent salivation. It is best to choose a latching nozzle.
7，Screw: use standard screw, compression ratio 2.8-3.0:1, length-diameter ratio: 18-22:1.
8， Cylinder temperature: the melting point of the resin is about 165℃.The optimal temperature for actual molding is 190-210℃, preferably 200-210℃.
