Mold manufacturing is a complex process, from design, processing, assembly, debugging and other steps to the final actual use. During the entire life cycle, the factors that affect the quality of the mold are mainly the following. ① Requirements for injection molding materialsDifferent plastics should use different steels, such as requirements for high polishing, corrosion […]

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,

Program control of injection speed 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

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

Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed and high efficiency, the operation can be automated, there are many designs and colors, the shapes can be from simple to complex, and the sizes can be from

Weld mark formation mechanism Weld marks (also called water lines) are intersection marks formed when molten plastic flowing out of gates at different locations in the mold converges. The reason for the formation of weld marks is that the temperature, pressure, and speed of the molten material flowing out of each gate are not completely

Injection molding principle Taking the plunger injection machine as an example, the granular or powdery plastic is first fed from the hopper of the injection machine into the barrel equipped with a heating device for heating, melting and plasticization to turn it into a viscous flow melt, and then in the column of the injection
