DGMF Core Pins for Molding

What are Core Pins?

Core pins are used in the plastic injection mold and die-casting mold. They are fixed elements used to create a void providing the desired shape in the injection molded or die-casted part. It is often easier to machine a core pin as a separate element and add it to the A-side or B-side as needed.

Steel core pins are sometimes used in aluminum molds to create tall, thin cores that might be too fragile if machined out of the bulk aluminum of the injection mold. The core pins are also used for part ejection from a die-cast mold.

Note:

A-Side of a core pin is sometimes called the “cavity”. It is the half of the mold that usually creates the exterior of a cosmetic part. The A-side usually does not have moving parts built into it.

B-Side is sometimes called the core. it is the half of the mold where ejectors, side-action cams, and the other complex components are located. On a cosmetic part, the B-side usually creates the inside of the part.

Plastic injection mold around these core pins to form small holes, or use them to perforate parts. They have a flat head to fit into a counterbored hole. Core pins can be machined to fit your application. They’re precision-ground to tight tolerances. Made of M2 tool steel, these pins are wear-resistant and stay sharp at high temperatures.
