Several aspects of the solution are considered

1. Equipment: Insufficient ejection force and insufficient ejection.

Ejection force is the force control used by injection molding equipment for demolding. For injection molding machines of different important levels, the maximum ejection force is different. The preset ejection force of the ideal injection molding process machine is basically sufficient, but it is not ruled out that the injection molded part is larger than the maximum injection range or the structure of the injection molded part is too complicated, and the grip force in the mold is too large. Comprehensive consideration of these issues is helpful to analyze the suitability of the ejection force. Condition.

Second, the injection mold injection molding mold

1. Unreasonable demoulding structure or improper position;

2. Insufficient draft angle;

3. The mold temperature is too high or poor ventilation;

4. The runner wall or cavity surface is rough;

5. The nozzle does not conform to the feed port of the mold or the diameter of the nozzle is larger than the diameter of the feed port.
