Example For Ejector Leader Pins And Bushings

Inlay method
*This method requires a high precision machining of the ejector pin's bushing hole and the back up plate's inlay hole to have them aligned accurately.
Striking method
1. Use of a long pin helps prevent deflection at the time of striking.
2. Can also serve as a support pillar, requiring less space.
