Ejector Systems Summary

The choice of part ejection methods is greatly influenced by the part design and plastic materials used. The correct choice is important because the quality of the molded part is affected by a good or bad designed ejection system. You have learned that the correct ejector system can eliminate:

  1. Runner system sticking
  2. Part damage from ejection
  3. Stress caused from poor ejection design
  4. A vacuum seal on cores of deep molded parts
  5. A vacuum seal on thin walled parts
