It is very important to give careful consideration to the way in which a component is going to be ejected from the tool. The design of the ejection system is one of the major factors in determining how efficient the tool will be in production.
The paramount requirement is that all components are ejected positively, without exhibiting any tendency to twist, distort or hang-back. In determining a satisfactory system, a number of factors have to be taken into account, including:
- The part geometry
- The material
- Gating
- Ejection balance
- Machine specifications
- Component finish requirements
