How can deformation of the moldings after ejection be prevented?

This fault points to various possible causes:

1. Recesses

Remedies: 

• Increase mold temperature
• Raise melt temperature
• Increase injection pressure
• Increase injection speed
• Vent mold more effectively

2. Differences in wall thickness, sharp transitions

Remedy:

• Increase mold temperature
• Raise melt temperature
• Reduce injection speed
• Change location of gate to improve flow conditions
• Adapt wall thickness to achieve a uniform melt flow
• Vent mold more effectively
