Dorian is from a Greek hydraulic equipment company and is responsible for the procurement of hydraulic components. At the beginning of the year, they developed a new hydraulic crane, which requires the use of hydraulic counterbalance cartridge valve. Dorian worked with a local manufacturer to make samples. During the equipment commissioning, it was found that the hydraulic counterbalance cartridge valve had no overflow function due to the back pressure. The hydraulic system was tested separately, but it was normal. Dorian felt that there was a hidden danger in the original design of the hydraulic counterbalance cartridge valve. The engineer thought that the function of the hydraulic counterbalance cartridge valve was not up to standard. Dorian was a little embarrassed. Dorian found website of AAK hydraulic valves on Google, and noticed that AAK had been supplying first-line brand hydraulic valves such as HydraForce, SUN Hydraulics, and HAWE for many years. Maybe he saw hope and sent an email to ask for help. According to what he said, the hydraulic counterbalance cartridge valve has no overflow function under the influence of the back pressure of the closed central circuit. I told him that it was probably a flaw in the design of the original hydraulic counterbalance cartridge valve. According to his hydraulic schematic diagram and original drawing of hydraulic counterbalance cartridge valve, AAK engineer not only determined that the problem was in the original design, but also had a solution. After knowing these, Dorian asked AAK to make samples. After 50 days, AAK sent 10 hydraulic counterbalance cartridge valve samples. 4 weeks after AAK hydraulic counterbalance cartridge valve samples were sent, Dorian told me that the equipment debugging was smooth and the market promotion had been started. I was asked to wait patiently for the batch order. The rapidity and stability of AAK optimized hydraulic counterbalance cartridge valve is the key to smooth equipment commissioning. It solves the contradiction between the rapid response and stability of the equipment in the early stage, and the flow change is moderate, the movement is stable, the safety overflow function is not affected by the back pressure, which can be applied to the closed center and open center hydraulic systems. 1. The middle section of the hydraulic counterbalance cartridge valve spool is provided with an inner concave ring, which is also the valve inlet. The right end of the inner concave ring has a cone, on which there is a two-stage stepped taper ring. The cumulative area of the cone is the same as the area of the cylinder end face at the right end of the counterbalance cartridge valve spool. This not only challenges the selection of design data, but also challenges the processing settings and processing technology. 2. The cylindrical end face at the right end of the hydraulic counterbalance cartridge valve spool is equipped with a balance adjusting spring. The adjusting screw at the back end of the spring is sealed with the back end of the counterbalance cartridge valve body, and controls the expansion and contraction of the counterbalance adjusting spring. 3. Fixed damping is installed between the inlet of the automatic closing valve and the pilot oil port. The hydraulic automatic closing valve is used in parallel with the adjustable flow valve to compensate the pressure without being affected by the back pressure. AAK hydraulic counterbalance cartridge valve, not affected by back pressure, you can also try a small order! https://www.aakindustry.com/info-det , ail/counterbalance-cartridge-valves-aak427

Giuseppe is from a hydraulic equipment company in Italy. As an old purchaser, he has been enjoying good luck. In the second half of last year, their company obtained the annual order of hydraulic power units used for the tail plate of electric vehicles, but the customer requested that the price should be reduced, and the hydraulic directional control valves used in the power unit should be reduced by 10%. The manufacturer of the hydraulic directional control valves who made the samples for them also agreed to reduce the price, but hidden trouble was brought to the quality at this time. In the random test of the electric vehicle, the tail plate did not rise flexibly. After disassembly, it was found that the hydraulic directional control valve was stuck. The manufacturer of the hydraulic directional control valves advised that it is an individual phenomenon, but the customer does not think so. After increasing the detection ratio, some tailboards still can not be opened. The customer asked for immediate solution, otherwise the annual order would be cancelled. The boss was very angry and requested Giuseppe to solve it. Giuseppe contacted more than 20 manufacturers of hydraulic directional control valves. They either disliked the low price or could not guarantee that there was no jamming. Giuseppe at this time is under great pressure. Giuseppe contacted me. Due to price, our cooperation is sporadic. According to the hydraulic directional control valve drawings provided by Giuseppe, AAK found that the original design caused processing difficulties and processing costs. I replied to Giuseppe that if the original design can be modified, AAK can accept the price and guarantee 100% no jamming. After 45 days, 100 hydraulic directional control valves were sent. A week later, Giuseppe sent the shipment schedule for the annual order. 8 months have passed. Last week Giuseppe informed that the customer wanted to ship the last batch of hydraulic directional control valves in advance. After using AAK hydraulic directional control valves, the customer no longer complained about the inflexible lifting of the tail plate. The hydraulic directional control valve is 100% free of jamming, due to 3 points: 1. The hydraulic directional control valve newly designed by AAK belongs to the spool valve type. The original vertical poppet type design is replaced by the "tumbling head" type design. The original function is not changed, and can be used to compensate for the imbalance of the valve spool in the chamber. At the same time, it can effectively compensate the original high torque in the assembly process, so that the valve spool can be controlled freely. Double protection hydraulic directional control valve, without jamming. 2. AAK adopts Swiss high-precision honing machine to finish the valve spool and cage, and the accuracy is guaranteed to be within 1μm. Unstable accuracy is the root cause of the stuck hydraulic directional control valves of the original hydraulic valve manufacturer. 3.AAK Hydraulic Valve has developed no less than 500 non-standard customized hydraulic valves for 7 world top 500 enterprises. If without unique skills, it is difficult to handle. Giuseppe privately told us that the boss attached more and more importance to him and wanted him to lead the whole procurement team because he successfully saved the annual order. AAK hydraulic directional control valves, flexible and free of jamming, you can also try it! https://www.aakindustry.com/info-detail , /hydraulic-directional-control-valves- aak331

Smith is from Mexico and has been smooth on purchasing hydraulic valves, but encountered a nail when purchasing a hydraulic relief valve with a wall thickness of less than 2mm. His boss received an order for a special hydraulic relief valve, requiring Smith's team to complete the sample within 45 days. The wall thickness of the valve cage of the hydraulic relief valve is less than 2mm, and the fitting clearance of the valve cage is 0.016mm-0.02mm. Thin wall and high precision. 4 hydraulic relief valve manufacturers, 3 rounds of proofing, 30 days passed, none of them succeeded, and the manufacturers all surrendered. The boss is not satisfied, and the team also complains that Smith does not know how to decline the boss, and Smith is helpless. Smith had to find a new hydraulic relief valve supplier himself. He consulted more than 20 hydraulic relief valve manufacturers online and offline, but only one was willing to try, and the others did not even have the courage to try. Smith found AAK on Google and left a message asking: can AAK make samples for a hydraulic relief valve with wall thickness less than 2mm? I replied directly that AAK shipped similar hydraulic relief valves 2 years ago. Smith may have seen hope, and directly told us that he wants AAK and another manufacturer of hydraulic relief valves to sample at the same time. My reply: AAK likes this kind of direct PK. If AAK hydraulic relief valve fails to meet the standard, the test order fee will be returned. 3 weeks later, AAK sent the hydraulic relief valves. 1 week later, Smith advised that the samples of AAK hydraulic relief valve has a wall thickness of the valve cage less than 2mm, the cylindricity was not more than 0.01mm, the roughness Ra was ≤ 0.2, and the pass rate was 100%. While the pass rate of another hydraulic valve manufacturer was 80%, Smith was surprised that the pass rate of AAK samples was 100%, and worried about the pass rate of mass production. I told him that the standard of the mass production would be same as the samples. The processing of this valve cage may be a hindrance for other hydraulic valve manufacturers, but AAK mass produced it 2 years ago. 1.Basic link: before processing, grinding the outer circle as Φ14.3, the heat treatment shall be complete and prevent deformation. After processing, ensure the inner hole Φ9.9, the cylindricity shall not be greater than 0.01mm. The outer circle shall be machined to ensure Φ14.1, and coaxiality with the Φ 9.9 inner hole is not greater than Φ 0.02. 2.Key link: process 4 ring grooves and 6 holes on the cage wall to ensure the size of 6 ± 0.01, and improve the requirements of symmetrical position of holes and grooves with respect to the center line, with the symmetry not greater than 0.025mm. Semi Fine honing the Φ 9.9 hole to ensure the inner hole Φ 9.97, and the cylindricity is not more than 0.005mm. 3. Tips link: self made mandrel with precise reference Φ 9.97 positioning and fine grinding of outer circle Φ 14, and coaxiality with Φ 9.97 hole not greater than Φ 0.025. Finish honing the inner hole to eliminate the clamping trace: smooth the hole with J95 oil stone Φ 10. The speed is 800-1000r / min to ensure the inner hole Φ 10 and surface roughness Ra 0.2. AAK hydraulic relief valves, focus on details, no deformation, high precision, welcome to try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak330

Surprisingly, within 3 months, Suker issued 3 batches of solenoid valves to AAK. Suker came from Türkiye and started to develop Chinese solenoid valve manufacturers last year. I received his inquiry about solenoid valves on December 22nd in 2022. Suker said that he has been following AAK for a while and wants to make AAK the preferred partner for Chinese solenoid valve manufacturer.   Our email communication was very smooth, except for payment, there were no obstacles. His first solenoid valve order amount was not big, which was over 6,000 US dollars. He needed payment terms of NET 30 days, but I directly refused. Then he requested for 30% deposit, I still refused and insisted on a 100% T/T. After more than a week of suspension, he suddenly said he would accept AAK's payment terms. I thought that after this order, he would not place any more order with AAK due to payment terms, because some customers naively believe that it is easy for them to find a Chinese solenoid valve manufacturer. Although I have a good impression of Suker, if I really lose this customer due to payment terms, it's not sad. With so many solenoid valve customers around the world, it's normal to loss several customers.   AAK, as a Chinese solenoid valve manufacturer, often ponders a question: What is a customer? 1. be able to agree payment terms. 2. Pay attention to the quality of solenoid valves.   This is called the customer. The order of these two cannot be reversed. You can make the payment, but are unclear about the industry rules for Chinese solenoid valve manufacturers, or uncertain about the quality details of solenoid valves, this is not a problem because we will take care of it for you. AAK has been producing hydraulic valves for 13 years, and AAK is the supplier of HydraForce for 9 consecutive years and Sun hydraulics for 5 consecutive years. What is there to worry about? But if you can't afford to pay but have high quality requirements, we can't do anything about it.   Chinese solenoid valve manufacturers ask themselves 3 questions: 1. The customer only looks at whether the price is cheap, is that so? 2. What other guarantees do customers want besides price? 3. How can I guarantee and he believes in my guarantee?   After Suker received our first batch of solenoid valves, I estimated that he does not want to change a Chinese solenoid valve manufacturer, otherwise he would not have placed 3 orders with AAK in 3 months. I remember joking with Suker last time: we asked for pre shipment payment, and you were just worried about the safety of over 6,000 US dollars. AAK has a house and factory in Ningbo, and my family is all in Ningbo. I couldn't have bought your 6,000 US dollars and run away.   You can try AAK if you are unsure of the solenoid valve manufacturer in China, or if you have some solenoid valves that someone else is not good at it.   AAK HYDRAULIC VALVES (582) 2023-05-14 https://www.aakindustry.com/info , -detail/solenoid-valve-aak582

After CNY, most of the hydraulic cartridge valve manufacturers in Ningbo started work on January 30. Because of the epidemic, many of us haven't returned to our hometown for 3 years, so AAK hydraulic cartridge valve started 3 days late, and also delayed answering the messages of some new customers in the CNY period. I reply to target new customers or new customers with clear messages first. Eugene, from Greece, left a message asking: How to solve the problems of unstable pressure regulation and squealing of hydraulic cartridge relief valve? After communication, it was learned that one of their hydraulic power units failed in the test run. The engineer found that the hydraulic cartridge relief valve was unstable in pressure regulation and there was a howl. This hydraulic cartridge relief valve was customized from a cartridge valve manufacturer in Ningbo, China. After the manufacturer modified it, it still failed to pass the test and the manufacturer gave up. Eugene saw AAK hydraulic valve in Google and left a message on our website. According to the analysis of the original hydraulic cartridge relief valve drawing and system schematic diagram, AAK engineers found that as long as the impact of the hydraulic system on the valve is reduced, it can not only avoid whistling, but also stabilize the pressure. Eugene didn't seem to believe that and needed us to give specific solution. Our engineer didn't recommend them to customers. He worried that customer will give our solutions to the original manufacturer to make improvements. I know the processing technology of the original manufacturer. Even if they know this solution, it is not sure to carry it out successful. AAK planned to optimize the original hydraulic cartridge relief valve in this way: As long as the processing accuracy is in place, the optimized hydraulic cartridge relief valve can isolate the oil inlet and return port when the system pressure is lower than the set pressure of the spring. When the system pressure exceeds the set pressure of the spring, the valve spool can be connected with the oil inlet and return port. The 3 advantages of stable voltage regulation, small impact and no vibration are reflected. 1. The hydraulic cartridge relief valve sleeve is equipped with large and small holes. The valve spool is installed in the small hole and plays a guiding role for the valve spool, so that the valve spool is more stable. The large hole is equipped with an elastic member seat, an elastic member and an adjusting rod, and the elastic member connects the adjusting rod and the upper elastic member seat. 2. An annular oil return hole is arranged outside the elastic member seat. An inclined hole for oil inlet is arranged on the outside of the valve spool. 3. The valve spool adopts the structure of slide valve, so the valve spool is not easy to deflect. A conical surface is machined in the middle of the valve spool, the valve sleeve is pressed on the conical surface, and the sealing line of the entire hydraulic cartridge relief valve is also on the conical surface. It seems that, as our engineer said, Eugene has no news after he got our specific plan. I was also ridiculed by the engineer that I believe too much in people, and will suffer in business. A week later, on February 10 today, Eugene's emailed us to start making samples and he will pay the fee immediately. AAK hydraulic cartridge relief valve has stable pressure regulation, small impact and no vibration. You can also try it! https://www.aakindustry.com/info-detail , /cartridge-relief-valves-aak498

Mura from Türkiye, a very polite customer, has purchased hydraulic cartridge valves from AAK for only 1 year. A few days ago, she needed to purchase a 7075- T651 hydraulic manifold weighing 2.5 tons, and contacted me. I politely declined because AAK does not have a processing center and cannot process a hydraulic manifold weighing 2.5 tons. Mura told me that 1 week has passed and this is the fifth hydraulic manifold manufacturer to refuse her. I told her that with such a large tonnage, she can only find a manufacturer for oil circuit blocks, not a hydraulic cartridge valve manufacturer. I can introduce an oil circuit block manufacturer in Ningbo to her, but she actually requested AAK to purchase this hydraulic manifold weighing 2.5 tons on her behalf. I hesitated a bit, Mura only said one sentence: In Ningbo, I only trust AAK. If the procurement of this 2.5 ton hydraulic manifold fails, the responsibility lies with her. I am quite moved. There is an old saying in China that a gentleman will die for the patron who recognizes his worth. If customers trust you like this, you have no reason to cause trouble for them. After confirming the contract for the 2.5-ton hydraulic manifold with Mura, I went to the oil circuit factory that had previous business dealings that day and urged them to complete the procurement of 7075-T651 materials that day. After the materials arrived at the factory, I made a request to visit the processing plant every 3 days to pay attention to the production process and manufacturing quality of hydraulic manifolds. The equipment is crucial for processing large volume and heavy hydraulic manifolds. We use Cincinnati Horizontal Machining Center for the processing of 2.5-ton hydraulic manifolds. Its X-axis, Y-axis, and Z-axis strokes are 4200mm, 2100mm, and 700mm respectively, ensuring that large hydraulic manifolds can be processed. Set a processing speed of 45m/min and use centralized timed lubrication to reduce guide rail wear, ensuring stable accuracy of the hydraulic manifolds and ensuring its geometric accuracy. Especially the 220 ° rotation function of the A-axis and the arbitrary 360 ° rotation of the C-axis can achieve 4-axis movement on one side of the spindle, ensuring processing efficiency. After 30 days, 10 hydraulic manifolds were produced and successfully shipped out. Yesterday, I received an email from Mura. The hydraulic manifolds shipped by AAK have been recognized by their engineers for the geometric accuracy, valve hole accuracy, and deburring effect. She can finally rest assured, and I can feel Mura's happiness from the lines of her email, at the same time, I am also at ease. AAK hydraulic manifolds, for the customers’ trust, can only do it, and do it well. You can also give it a try!

What Is the Difference between Insert Molding and Overmolding Plastic injection molding is one of the most widely used processes for manufacturing high-quality and extremely precise parts. The process is known for its multiple advantages. Consequently, a wide range of industries have adopted this part manufacturing method. There are many types of injection molding technologies currently in use, depending on the parts to be produced. Among the many types, overmolding and insert molding are the two most common injection molding technologies. 1. Overmolding As the name implies, overmolding is a process of molding one material on another. The first component is made in an injection mold and then placed in the second mold, where overmolding material is added. This technology combines a variety of plastics to achieve practical or aesthetic purposes. For example, people may use plastics of different hardness to mold soft plastics over hard plastics to make the parts easier to grasp. The use of multiple colors of plastic in overmolding parts can also distinguish the products from those of other brands. Overmolding is often used on the handles of tools such as screwdrivers, electric drills, or toothbrushes. The advantages of overmolding injection molding are: (1) Improve material flexibility (2) Long service life (3) Enhance security 2. Insert molding Insert molding is a subset of custom injection moulding technology, similar to overmolding. Before the actual injection molding, the metal part is put into the mold cavity, and the insert is accurately positioned in the mold by manual operation or mechanical arm. Then the mold is closed and the plastic is molded on the insert to form a part. Most of the finished parts produced by this method are a combination of thermoplastics and metal parts, which are often used in aerospace, automotive and medical fields. The advantages of insert injection molding are: (1) Reduce assembly and labor costs (2) Reduce the weight of parts (3) Shorten assembly time The above is the insert molding vs overmolding difference Both have their own advantages and applications. The corresponding technology can be selected according to the type of parts to be manufactured. If you want to know more details of insert molding vs overmolding , please visit our website. As one of mould manufacturers in china, we will do our best to meet all the needs of customers.

Types Of Plastic Injection Mold Polishing Introduction to the plastic injection mold polishing These days, industrial products are developing in the direction of product high quality as well as product diversification, in this way mold quality is going to have an influence on product quality directly, so improving mold quality has become an important task. Plastic injection molding polishing is a technology that helps to obtain a smooth mold surface. It is very different from the surface treatment of other industries. It has higher standards for polishing process, smoothness, and geometric accuracy. Types of plastic injection mold polishing service (1) Mechanical polishing Mechanical polishing is a method of removing the protruding part on the workpiece surface by cutting or plastic deformation on the surface of the material to obtain a smooth surface. Whetstone, wool wheel, and sandpaper are usually used for manual operation; if the surface quality is high, the processes of ultra-precision grinding and polishing should be used. This technology can reach a surface roughness of Ra0.008 μm, which represents the best value for mold polishing. (2) Chemical polishing Chemical polishing refers to the plastic injection mold polishing process of immersing a material in a chemical medium to ensure the micro-protrusions on the surface of the material dissolve before the dents to obtain a smooth surface. The method can be used to polish workpieces with complex shapes and can polish multiple workpieces at the same time, with high efficiency. The surface roughness that can be obtained by chemical polishing is usually Ra 10 μm. (3) Electrolytic polishing The basic principle of electrolytic polishing is the same as that of chemical polishing, which is to selectively dissolve the surface of the material to form a smooth surface. Compared with chemical polishing, it can eliminate the influence of the cathode reaction to produce a more significant effect. (4) Ultrasonic polishing Ultrasonic polishing is a method that uses ultrasonic vibration of the tool part and uses abrasive suspension to polish brittle hard materials. The workpiece is immersed in the abrasive suspension, and then placed in an ultrasonic field together with the suspension, and the surface of the workpiece is ground and polished by the action of ultrasonic waves. Ultrasonic machining has a small macroscopic force, so it will not cause the deformation of the workpiece. (5) Fluid polishing Fluid polishing relies on the flowing liquid and the abrasive particles it carries to erode the surface of the workpiece to achieve the purpose of polishing. Hydrodynamic grinding is driven by hydraulic pressure, the polymer in the medium flows at low pressure, and the abrasive particles are usually silicon carbide powder. (6) Magnetic grinding and polishing Magnetic grinding and polishing of plastic molding china refer to the use of magnetic abrasives to form a brush under the action of a magnetic field to grind the workpiece. The method has high processing efficiency, good quality, and easy control of processing conditions. The surface roughness obtained by this method can reach Ra0.1 μm.

Two shot moulding, also called double shot injection molding, double shot moulding , multi shot injection molding or 2k injection moulding is one category of injection molding using two different thermoplastic materials to produce injection molded parts in two colors or two components in the double injection molding process to produce 2 shot molding in large quantities quickly, economically and efficiently. Multi multi injection molding has characteristics as below: Two shot injection molding, co-injection, two color injection molding and multi component injection molding are all variants of advanced molding techniques. A combination of hard plastics and soft materials. Two-step process is executed in a single press cycle. Combine two or more components to eliminate additional assembly costs. Keyplast as top of 2 shot injection molding companies, with years of expertise and cutting-edge technology, we offer precise and efficient 2 shot injection molding solutions for a wide range of industries. Our skilled team and state- of-the-art facilities ensure top-notch quality and fast turnaround times. Trust KeyPlast for your complex multi material injection molding needs. Contact us today to discuss your project and experience the excellence of KeyPlast's double shot molding capabilities. Two Shot Molding Process Two shot injection molding has two stages in the whole process. Firstly one shot of materials is injected into a mold and cooled to form a solid part. Secondly, the mold opens and rotates 180 degrees and then closes. The second shot of materials is injected into the mold, through or around the first molded part. After sufficient cooling, the mold opens and the multi-resin molded part is ejected. 2 shot moulding has key factors as below: Melting temperature for the materials Wall temperature for the mold Injection speed for the molded parts Delay time between injections Temperature of the components Two Shot Injection Molding Design Guide The mold used in two shot molding consists of different tool sets. In rotating platen settings, these two shot injection molding tools share the same core, but different cavities. The runner must be designed to close during its inactive forming step. Wall thickness is an important two shot molding design consideration when designing parts for a number of reasons: Due to the molding pressure from the second step, the substrate wall should be thick enough to withstand the force without collapsing. Walls should not exceed traditional thickness guidelines to produce effects attributable to irregular cooling. To ensure accurate and thorough flow of 2k molding material into all parts of the cavity, the wall thickness should not fall below a certain minimum value.

Over molding of keyplast is a special plastic molding process. Overmolding custom injection molding is similar to the two-color molding or two-shot molding process. Over moulding can make the surface of the product full of softness and increase product functionality and added value. With this technology, product functions can be increased, such as noise reduction, vibration reduction, waterproof, anti-collision and added value. Overmolds is widely used in mobile phone protective shells/mobile phone protective sleeves. Overmolding Process Plastic overmolding has a process in which a certain materials used in injection moulding is molded in a primary plastic mold, and the molded part is taken out and placed in a secondary molding mold to inject the same or another plastic material into tpu overmolding process. Overmolding process has key factors as below: 1. The chemical or mechanical bonding strength between the polymers is not enough, and the material of single or multiple parts is not completely filled; 2. Flashing of burrs on single or multiple material parts. 3. The injection molding machine must maintain the consistency of injection molding. Insert Molding VS Overmolding Insert molding and overmolding injection molding are very similar, but there are significant differences between the two processes. Injection overmolding is a two-step process in which two separately molded parts are combined to enhance product functionality. While insert injection molding is a slightly faster process because the two plastic materials are molded at the same time. Besides, over molding can not only give designers and engineers more creative freedom, but cost-savings of assembled parts as well. Whether you choose insert molding or over moulding, we understand the importance of creating a strong bond between components. We'll recommend the right innovative polymer solution, like thermoplastic polyurethane overmolding (TPU overmolding) to deliver the chemical adhesion you need. Overmolding VS Two Shot Molding 01 Two-shot injection molding Two-shot injection molding is also called two-color mold injection. 2 shot injection molding, also called 2k injection moulding, is to inject two plastic materials on the same injection molding machine in two moldings, but the product is only ejected once. The mold is usually completed by a set of molds and requires a special two-color Injection molding machine. The same back mold, different front molds, high production efficiency, good product quality, suitable for mass production. 02 Over molding Over molding, the two plastic materials are not necessarily injected on the same injection molding machine, but are molded in two parts; after the product is taken out from one set of molds, it is placed in another set of molds, inject molding. Therefore, this molding process is usually completed by two sets of molds, without the need for a special two-color injection molding machine. Injection overmolding is to first take part of the product out of injection molding, and then put it into another injection molding machine for injection molding. The efficiency will be slower and the cost will be higher, so it is suitable for small batch production. Why so many manufacturers like over molding? Regarding this problem, we can learn one or two of the advantages of overmolding injection molding. First, the product quality of over-molding can be improved. Injection overmolding can optimize the copolymerization of hard and soft materials to form strong molecular bonds. The result is a single part with production and feature advantages. It can be used for various product designs in injection moulding applications. The injection overmolding also allows the use of transparent plastics, colorful graphics, and fashionable finishes for molding, thereby improving your product functionality and market value. Second, plastic injection overmolding can reduce the cost of production. Complete the entire production process in one injection molding machine, overmolding injection molding effectively reduces unit costs, reduces processing and secondary assembly, and reduces costs and waste associated with assembly defects, thereby shortening the molding cycle and improving work efficiency. Furthermore, china injection molding factory can also improve people's experience. Over the past 10 years, it has completely changed the aesthetic standards, design ideas, and functional requirements of consumer products. The use of plastic materials with different textures has improved the touch and function of products. Many of the common toothbrushes and mobile phone protective cases in our lives are products produced by using injection overmolding technology.
