Mold pins are used in the plastic molding and die casting dies. They are a fixed element used to create a void providing the desired shape in the molded or cast part. It is often easier to machine a mold 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 molded part. The pins are also used for part ejection from a die. Note: A-Side 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.
