Shrinkage rate of injection mold is always an important part in the development of injection mold. This ring has a tremendous impact on the size of the plastic. After the structure of the die is determined, all parts of the die can be designed in detail, that is, the size of the template and parts,

In the process of injection moulding, the moisture content of material should be within a relatively low range to ensure the normal injection moulding and the normal physical properties of product materials. The water content of injection material is too high. First, there will be bad appearance of silver wire on the surface. Secondly, water

Plastic injection moulding is an efficient and mass production method, which can realize one-time moulding of plastic products with complex shapes. In the mould industry, in order to produce injection moulds with high precision, high quality and complex surface, we must use advanced computer aided design and manufacturing software to compile reasonable processing procedures, which

Plastic moulds, which are matched with plastic moulding machines in plastic processing industry, give plastic products complete configuration and accurate size tools. According to the different forming methods, it can be divided into different types of moulds.   mold making   Injection Mould It is mainly a kind of mould which is widely used in

The process of injection molding mainly includes four stages: filling, holding, cooling and demolding. These four stages directly determine the quality of the product. It is a complete continuous process. Injection parameters   Injection parameters Injection pressure   Injection pressure is provided by the hydraulic system of the injection system. There are many factors affecting

Common automotive plastic parts are: dashboard body skeleton, battery bracket, front-end module, control box, seat support frame, spare placenta, fender, chassis cover, noise partition, rear door frame, etc. Most of the panels of automobile plastic parts are made of engineering plastic ABS or abs/pc.   Generally, doors, dashboards, bumpers and gearboards are all made of
