What is a Core pin?

The core pin is one of the mold parts. It is required when making shapes such as "holes" and "bosses for screwing". There is an "eject pin" as a part with a similar shape, but this has the function of moving at the same time when the mold opens and pushing out the molded product, but the core pin is just a part for making the shape. , Even when opening the mold, it does not move in a fixed state.

Application of Core pin

It is used for molds that mold parts that have shapes such as "holes" and "bosses for screwing". Since as many core pins as there are "holes" and "bosses for screwing" are required, a large number of core pins are used in molds for parts used in products with many screws. For small precision products, the core pins are also very thin, so it is necessary to be careful about damage during molding.
