Why does the platen of an injection molding machine crack?

1. Too much injection pressure, too fast speed, more filling, injection, too long pressure holding time, will cause excessive internal stress and cracking.

2. Adjust the die opening speed and pressure to prevent the rapid and strong drawing parts from cracking.

3. Adjust the mold temperature appropriately, limit the speed of cooling body flowing through the mold, so that the parts are easy to demoulding, plastic degradation in the injection cylinder, causing the rupture of plastic molecular structure, reduce the temperature of the injection cylinder in all areas, reduce the pressure back, use the exhaust injection cylinder to ensure the correct operation of the discharge hole and each hole set the correct temperature.

4. Prevent cracking due to welding marks and plastic degradation resulting in low mechanical strength.
