Purpose Of Ejector Pins:

The purpose of an ejector pin is to apply a force to eject a part from the mold. In some cases this process can leave surface marks known as read-through or pin push. To avoid this the goal of the designer is to position the pins to minimize cosmetic witness marks on your finished parts.

Ejector pins are one of the least expensive components of a mold base however they are also one the most critical components. The mold maker will spend hours on machining and polishing the cavity and core to ensure the processor will achieve a high-quality plastic part.

However, choosing a lower quality pin could affect all of these hours and cause major damage to the mold if there is a failure. For this reason, it is critical to choose a high-quality pin that matches the application (more info on this below). Ejector pins are in the B-side mold half which is also call the stationary half. This is the half in which the plastic parts will stay when the mold opens. Once the mold is opened, the pins will extend into the mold cavity by the movement of the ejector plate, push the part out, and then retract, allowing the mold to close and be refilled.
