injection machine screw barrel

Several aspects that need attention to reduce the wear of screw and barrel of injection molding machine and extend life of injection mold

The screw and barrel of the injection molding machine works for a long time under high temperature, high pressure, high mechanical torque and high friction environment. The first few factors are required by the process conditions, while the loss caused by friction is inevitable. Generally, the screw and barrel is subjected to surface nitriding treatment

How to determine plastic pressure drop in injection molding?

The plastic skin formed on the mold wall reduces the cross-sectional area of ​​the plastic flow, resulting in a pressure drop. There is a maximum limit to the pressure that can be obtained on the injection molding machine to push the screw at the set injection speed. The pressure required to push the screw forward

Maintenance points for the electrical system, hydraulic system, clamping part and injection part of the injection molding machine

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

Color difference control of injection molding products

Color difference is a common defect in injection molding. There are many factors affecting color difference, including raw material resin, masterbatch, mixing of masterbatch with raw material, injection molding process, injection molding machine, etc. In the actual production process, we generally control color difference from the following five aspects. Choose an injection molding machine with

How to determine plastic pressure drop in injection molding?

As the plastic flows through the injection molding machine and different parts of the mold, there is a loss of pressure on the plastic flow front due to drag and friction. In addition, as the plastic contacts the mold wall, it begins to cool, increasing the viscosity of the plastic and requiring additional pressure to
