Injection molding machine production is generally 24 hours a day. For machines that are in working condition for a long time, we must do a good job of maintenance and try to find and solve problems before the machine fails. Otherwise, once the machine fails, it must be stopped and repaired, affecting production. Therefore, it […]
Injection molding machine Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the

The program control of the injection speed is to divide the injection stroke of the screw into 3 to 4 stages, and use the appropriate injection speed in each stage. For example: slow down the injection speed when the molten plastic first passes through the gate, use high-speed injection during the mold filling process, and

Injection molding machine production generally operates 24 hours a day. For machines that are in working condition for a long time, we must do a good job in maintenance and strive to find and solve problems before the machine breaks down. Otherwise, once the machine fails, production must be stopped and repaired, affecting production. Therefore,

PE is a crystalline raw material with very little hygroscopicity, no more than 0.01%, so there is no need for drying before processing. PE molecular chains have good flexibility, small forces between bonds, low melt viscosity, and excellent fluidity. Therefore, thin-walled long-flow products can be formed without too high pressure during molding. The shrinkage range

The working conditions of plastic molds are different from those of cold stamping dies. They generally have to work at 150 degrees Celsius to 200 degrees Celsius. In addition to being subject to a certain pressure, they also have to withstand the influence of temperature. According to the different usage conditions and processing methods of

In order to strengthen the hardness of the metal surface, many manufacturers will use the quenching process to promote the production of moulds, and the cracks generated after the quenching of the moulds are a defect in the heat treatment process *, which is likely to cause the processed moulds to be scrapped. What are
