The role played by injection mold manufacturers
Since playing with plasticine when we were young, we have experienced the diversity of everything in the world for the first time in a variety of cute molds. A small mold seems to have magical functions and can generally turn disorder into tangible. Really showed it before my eyes. What role do injection mold manufacturers play in our lives today?We all know that an increase in efficiency in the production process means an increase in profits, so one of its functions is to help producers increase their production profits. Because the use of molds that have a fixed shape and built according to their own production needs means that the time used for production is greatly shortened. You only need to put the raw materials into the mold to finalize the product you want. When the benefit is unified with the convenience of production, what can be saved is not only the production cost, but also the labor cost of mental labor and manual labor, etc.In addition, injection mold manufacturers also record the products on the production line in the fixed form of the mold, which is equivalent to making a record file for them to preserve the development history of these products. This may be inadvertently Moment played an unexpected role. There was once an adult with some diseases who relied heavily on the cup he used since childhood, so his mental state deteriorated sharply after losing it, which was worrying. At this time, the manufacturer looked through the production inventory and found that the mold of the water cup more than ten years ago was still preserved, so he used this to find out from the historical years to rebuild a water cup for him, which greatly improved his mental condition. This is another unexpected function of it.Philosophers once said: 'Life is always full of unexpected surprises', which means that life is always full of unexpected surprises. We may not have a complete understanding of the role of injection mold manufacturers, but with the in-depth contact in life, we will slowly discover more of its beauty and bring us more unexpected gains.

How to find a good reputation injection mold manufacturer
Has any careful friend noticed the material of the household items we use in our lives? I found out that most of these household items are made of plastic, and few of them are made of all-iron and all-steel. But have any friends thought about how these plastic products are made? Is it to shape them like plasticine? So, where can we find such trustworthy injection mold manufacturers?1. Choose the mold manufacturer according to the quality of the moldTo find this injection mold manufacturer with good quality and low price, we have to pay attention to what the quality of this manufacturer looks like.      (1) The mold finish is poor, there are rust marks on the surface of the cavity, and the mold is poorly vented.(2) The gating system of the mold is defective, the cold slug well should be enlarged, the runner, polished main runner, runner and gate should be enlarged.(3) The material temperature and mold temperature are low, and local heating of the gate can be used if necessary.(4) The processing pressure is too low, the speed is too slow, the injection time is insufficient, and the back pressure is insufficient, resulting in poor compactness and dark surface.(5) Plastics must be fully plasticized, but the degradation of the materials must be prevented, the heating must be stable, and the cooling must be adequate, especially for thick-walled ones.(6) Prevent cold material from entering the part, use self-locking spring or lower nozzle temperature when necessary.(7) Too much recycled materials are used, plastics or colorants are of poor quality, water vapor or other impurities are mixed, and lubricants used are of poor quality. (8) The clamping force should be sufficient.2. Consider based on some factorsThen, if we want to find a trustworthy injection mold manufacturer, we must first examine whether it is a reliable mold design manufacturer, which is measured from the injection mold factory's technology, experience, business scale, and management philosophy. In addition, it is necessary to check whether the other party has a one-stop service manufacturer from mold design and manufacturing, product injection processing, plastic shell surface treatment (oil injection, silk screen, etc.), so as to avoid multiple suppliers from participating in the final product. In manufacturing, the risk is reduced to the greatest extent. After the comparison, the product after-sales service capability of the injection mold factory should be investigated, and all factors should be measured together, and finally an excellent supplier of the injection mold factory that meets the needs of the company is selected.Based on our above understanding, we can find that there are reasons why so many people choose injection mold manufacturers with good quality and low price. In fact, these plastic products are solidified through a series of processing methods through customized special molds. This is also determined by the characteristics of the plastic itself. The plastic has a strong moldability and a very light weight. Whether it is used as a storage box or a tableware cup, it is light and resistant to fall.

What are the best ways to start when choosing a Shenzhen injection molding factory
When it comes to injection molding, many people may be relatively unfamiliar, but many items that can be touched by hands in people’s lives actually require injection molding, such as some plastic tableware and children’s plastic toys. Wait, the scope of application of this process in people's lives is still very wide, so the number of injection molding plants in Shenzhen has also increased significantly in recent years. The following is a detailed explanation of related matters when choosing Shenzhen injection molding plant.1. Start with the manufacturer’s technical strengthAfter years of technological development and update, the injection molding industry has now reached a new height in industrial technology, but this is only for those large manufacturers with particularly strong comprehensive strength. As users, when they need to cooperate with manufacturers, they should first consider their technical strength, especially under the premise of relatively higher requirements for injection molding technology. Therefore, strong manufacturers are given priority. The goal considered is a common choice for more users.2. Start with the manufacturer's after-sales serviceIn addition to starting from the strength of technology, the manufacturer's related service system in the after-sales aspect is also an aspect that should be focused on. It is important to know that the process of using injection molding usually involves larger batch production. If some problems occur in this process, it may have an adverse effect on the user. Therefore, the quality of the after-sales service of the manufacturer is still This is one of the points to be paid more attention to.I believe that after seeing this, people will be able to have a more detailed and in-depth understanding of where to start when choosing a Shenzhen injection molding plant. Over the years, the injection molding industry has developed rapidly in this hot land of Shenzhen, and has formed a mature and complete industrial chain. However, users should try their best to eliminate blindness when choosing between a large number of Shenzhen injection molding plants. Focusing on the investigation, it can often bring the desired results.

What are the characteristics of an excellent Shenzhen injection molding factory
The probability of plastic products appearing in people’s lives is very high. From computer-related equipment that needs to be used frequently in work to plastic products such as tableware that need to be used frequently in life, in fact, they are gradually processed and manufactured through the preliminary process of injection molding. Once completed, the injection molding plant has also developed rapidly due to the booming plastic products market. So what are the characteristics of an excellent Shenzhen injection molding factory? Let's make a detailed explanation on this issue.1. Rich experience in the industryWith the continuous development of the times, the injection molding industry is constantly optimizing and updating in all aspects. The continuous increase in the number of injection molding manufacturers is essentially a side manifestation of the healthy development of this industry. However, the performance of participants in any industry cannot be exactly the same in all aspects, and even in some aspects there will be worlds apart, and manufacturers that do well in the injection molding field will inevitably have a wealth of work experience. Experience will also force the industry to move forward.2. Have a perfect service systemIn addition to rich experience in the field of injection molding, manufacturers that have done a good job in the field of injection molding are in fact more complete in the construction of the service system. In many people's eyes, the injection molding process is relatively simple, but it only looks simple. In fact, it still has relatively high requirements for precision, especially in some precision manufacturing fields. Requirements, there will be a gradual adaptation process for users in the later use, and in this process, the perfect service of the manufacturer is required as a strong support.After understanding this, I believe that people have a better understanding of the relevant characteristics of excellent injection molding plants. The market prospects of the plastics processing industry are very bright. This does give the Shenzhen injection molding plant room for development. However, if it is from the user's point of view, it will still rely on it when choosing a cooperating manufacturer, such as The two aspects just mentioned should be regarded as necessary prerequisites, so that it is easier to find the ideal partner.

What kind of Shenzhen injection molding factory will be favored by more users
Although the injection molding process is almost inaccessible to people, the production of plastic products in life is inseparable from this special process. After years of continuous technological update and development in the industry, Shenzhen Injection Molding Factory has been able to unite with related downstream manufacturing companies to bring more high-quality plastic products to the lives of modern people. So what kind of injection molding factory will be favored by more users? Next, a detailed explanation will be given on this issue.1. Advanced production technologyIn the past, the technical level of the injection molding process was relatively low. In many special industries with precision injection molding requirements, there is still a high dependence on foreign technology. However, with the development of the times, many injection molding factories engaged in the injection molding industry in Shenzhen have also mastered advanced production technology, and are fully able to reach the relevant international standards. In this way, users who have higher requirements for production technology will be better off. With better choices, and manufacturers with advanced production technology, they will inevitably be able to provide users with products with better quality.2. Have a good market reputationThe number of manufacturers engaged in the injection molding industry has increased rapidly in recent years. In order to gain the favor of more users, in addition to having advanced production technology, it must also have a good market reputation. After all, for many For new users with relevant selection experience, when choosing a Shenzhen injection molding plant, they will give priority to the market reputation to carry out corresponding screening.I believe that after detailed explanations of the aforementioned two aspects, people now have a more detailed understanding of what kind of injection molding plant will be favored by more users. Generally speaking, the development of Shenzhen injection molding plant is also a process of gradual growth of the industry, and it has also played a certain role in promoting the continuous development of the economy and society. When users choose injection molding partners, they should proceed from the above two points. Strict inspection will do.

Analysis of common process problems in Shenzhen injection molding factory
The injection molding process may seem simple, but it is not. The injection molding process has strict requirements on mold temperature and pressure, operation and equipment. A little carelessness will cause problems in the appearance and structure of the plastic parts, and a series of difficult conditions such as discoloration bubbles will occur. Today, the editor summarized the process problems that Shenzhen injection molding factory often encountered in the production process, and hope to help everyone.1. Insufficient product injectionInsufficient product injection is often due to the fact that the material has solidified before filling the cavity. Of course, there are many other reasons. The main reasons for the equipment are: the hopper is interrupted; the neck of the hopper is partially or completely blocked; the feeding amount is not enough or the feeding control system is not operating normally; the plasticizing capacity of the injection press is too small and the injection cycle is abnormal due to the equipment. The injection pressure is too low; the injection pressure loss during the injection cycle is too large; the injection time is too short and the total pressure time is too short; the injection rate is too slow, etc.2. Flashing materialProduct overflow is often caused by the defects of the mold. Other reasons are that the injection force is greater than the clamping force. The temperature of the material is too high, the exhaust is insufficient, and the mold is overfilled with foreign objects. Mold problems: The cavity and core are not tightly closed, the cavity and core are offset, the template is not parallel, the template is deformed, and the amount of square meters you fall into the foreign body, and the exhaust is insufficient. Equipment problem: The projected area of the product exceeds the injection area of the injection press, the injection press template is installed incorrectly, and the injection cycle caused by the equipment is abnormal.3. Product dents and poresProduct dents are usually due to insufficient force on the product, insufficient material filling and unreasonable product design. The dents often appear in the thick-walled part close to the thin wall. To determine the cause of the pores, it is only necessary to observe whether the bubbles of the plastic product appear instantaneously when the mold is opened or after cooling. If it appears instantaneously when the mold is opened, it is mostly a material problem, if it occurs after cooling, it is a problem with the mold or injection molding conditions.Temperature is a very important process parameter in Shenzhen injection molding plant. Improper temperature will cause various process problems. Too hot materials cause excessive shrinkage and too cold materials will cause insufficient filling and compaction; in addition, the temperature of the mold is also very important. Too high mold temperature causes the material at the mold wall to not solidify quickly and the mold temperature is too low. Insufficient mold filling and excessively high mold temperature can also cause various problems.

The reason and solution of the process problem in the mold of Shenzhen injection molding factory
The craftsmanship level of the Shenzhen Injection Molding Factory is the key to the quality of its products. Any problems with the mold pressure and temperature equipment may cause product failures. Today we talk about a common product problem that is stuck in the mold. This problem is mainly caused by poor molding, insufficient injection, and incorrect mold design. If the product is pasted, the in-mold injection molding process cannot be normal. Today we will analyze the possible causes of this problem in detail.(1) Mold problemMold problems are the main reason for the sticking. We need to pay attention if the plastic sticking into the mold is caused by insufficient injection, do not use the ejection mechanism; we can remove the undercut (sink), remove the gouge nicks and other scars to improve The smoothness of the mold surface attempts to solve this problem. The movement direction of the polishing mold surface should be consistent with the injection direction, and the effective ejection area of the slope should be increased, and the ejection position should be changed to check the operation of the ejection mechanism. If the problem cannot be solved effectively, check whether the mold is offset when opening the mold. If the part or mold design is not good, it needs to be redesigned.(2) Injection molding problem:The sticking caused by the injection problem is easier to solve. We can try to increase the release agent or improve the release agent, adjust the material supply, reduce the injection pressure, shorten the injection time, and reduce the total pressure time. In addition, the mold temperature can also cause the paste. We can reduce the mold temperature Increasing the injection cycle can easily overcome the abnormal injection cycle caused by the injection conditions.(3) Material issuesPasting caused by material problems is more common, but it is easier to handle. We only need to remove the material pollution, add lubricant to the material and try to dry the material to solve it.In addition, injection molding equipment problems can also cause products to stick in the mold. Shenzhen injection molding plant needs to repair and maintain the equipment regularly. Generally, the ejector mechanism needs to be repaired. If the ejector stroke is insufficient, it needs to be lengthened. We also need to regularly check whether the templates are parallel. Other failures of machinery and equipment may also cause this process problem, so we need to repair the equipment failures in time to overcome the abnormal injection cycle caused by the equipment.

Production process of Shenzhen injection molding factory
Injection molding is the current mainstream plastic mold molding process. It melts the plastic at high temperature and then pours it into a prepared mold and applies a certain pressure, so that after cooling, we can get a plastic product that is consistent with the shape of the mold. This method is very suitable for mass production of plastic parts. Today, let’s take a look at the production process of the Shenzhen Injection Molding Factory of Goodtec Industrial Plastic Parts.1. Clamping injectionClamping: the process of mold from opening to locking. It is divided into several stages: rapid mold clamping, medium-speed mold clamping, and low-voltage protection and high-pressure mold clamping. This process is to protect the mold and lock the mold smoothly and smoothly. Injection: The screw advances to squeeze the molten material into the mold. The injection stage is divided into injection and pressure holding. Injection is to make the melt material in front of the screw head advance according to the set parameters. The melt material gradually fills the mold under the push of the screw. Because the high temperature melt material shrinks during the curing process, the melt material must be filled again. This feeding stage is to protect Pressure.2. StorageStorage material is also called melt glue. After the melt is consumed in the injection stage, the amount of material in the next cycle needs to be supplemented. The storage is the process of supplementing the melt and measuring. After the pressure holding is over, the screw rotates to transport the material from the back forward. During this period, the material melts and accumulates on the screw head due to the shear heating. The screw does not actively retreat during the storage process, but as the fabric in front of the screw gradually increases and the pressure is established, the nozzle is blocked by the material in the mold and the screw is pushed backward by the molten material to stop at the metering point. The resistance that the screw receives in the process of retreating is called back pressure, which is also the pressure built up by the melted material in front of the screw. The resistance of the screw retreat can be adjusted through the back pressure valve to make the front end melt more dense.3. Shoot back coolingAfter the material storage is finished, the screw actively moves back a small distance to reduce the melting pressure of the screw head. Prevent overflow caused by excessive pressure. In this process, the injection molding machine is only responsible for timing the cooling water on the mold to exchange heat. The cooling time for the next action is relatively large in the entire cycle.After the cooling is complete, we can open the mold. During the mold opening process, we need to keep the movement smooth and smooth without jitter, and the position of the mold opening must be kept accurate. After the mold is opened, it will be found that the preform is difficult to remove, so we will set a push plate on the abrasive tool in advance, and the preform will be easily ejected with just a light push. The above is the basic production process of Shenzhen Injection Molding Factory.
