In recent years, the plastic shell of switching power supply has been widely used. The emergence of the plastic shell of switching power supply makes it more safe for everyone to use the plastic shell of switching power supply. The plastic shell of switching power supply is a very useful…… MORE
The power supply plastic shell has been quite active in our life. Take our common mobile phone charger shell as an example, its main material is made of plastic. A very common feature is that it plays an insulating role. For example, our notebook power supply plastic shell or electric ve…… MORE
Injection molding is a specific cycle. There are five factors that affect injection molding: temperature, speed, pressure, position and time. These five process factors determine the quality of injection molding. The quality problems often encountered in injection molding are mostly caus…… MORE
1、 Light weight led waterproof power supply plastic shell is a relatively light material, with a relative density of 0.90~2.2. Obviously, can the plastic shell of LED waterproof power supply float to the water? In particular, the foamed led waterproof power supply plastic shell has micro…… MORE
At present, the proportion of plastic mold in the whole mold industry is about 30%, and the proportion in mold import and export is as high as 50-70%. In recent years, plastic molds have developed rapidly in China, and plastic products are more and more widely used, providing a broad mar…… MORE
1. Shrinkage in injection molding is a common problem in injection molding, especially for plastic products with high surface quality requirements. Therefore, with the continuous improvement of injection molding technology, it is imperative to minimize the shrinkage of injection molding …… MORE
Large medical devices are relatively expensive products, and their volume is also relatively large, so it is troublesome to maintain them in case of problems. Therefore, its maintenance is very important. If there are problems, don't panic. If you can solve them, you will know how to do …… MORE
The quality of injection molding products is the premise and guarantee for the development of injection mold processing plants, so how to control the quality of injection molding products has become the primary task. What on earth should we do? 1) Do not easily determine the injection mo…… MORE
Injection molds are customized for different plastic products, but the structure of injection molds has many similarities. Therefore, in order to manufacture molds more efficiently, injection mold processing plants began to use some standard molds. In the custom mold opening, injection m…… MORE
The defect of insufficient filling during injection molding is that the mold is not full. So what is the reason for this defect, how can we find the reason for this defect, and how to solve it? 1. If we set the injection volume of the injection molding machine to the maximum during injec…… MORE
1. Good product structure (1) product design should try to avoid unnecessary side concave and the use of mold core pulling mechanism, so as to simplify the structure of the mold and facilitate mold processing. (2) Plastic products should have appropriate wall thickness and uniform wall t…… MORE
