Design Guidelines
Part Ejection
Protomold uses pins to eject parts from the mold during production. Designers should be aware of the need to accommodate such pins.
The Protomold Rapid Injection Molding process uses ejector pins of various sizes to push the plastic part out of the mold after it has solidified. The sizes and arrangement of these pins are selected to minimize the impact on your part design.
Figure 1 is an example of the illustration Protomold provides early in the process of designing the mold so that the location and size of both the gate(s) and ejector pins can be approved.
