Mold Core Pins are used in plastic molding and die casting dies. They are fixed elements used to create voids that provide the desired shape in molded or cast parts. 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 mold. The core pins are also used for part ejection from a die.

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