Core pins are used in the plastic molding and die casting dies. ... The pins are also used for part ejection from a die. 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.
DGMF's Core Pins are manufactured from precision ground hot work steel. They are available in both high hardness SKH51 (58-60 RHC) and soft hardness SKD61(48-52 RHC).
CORE PINS FROM PRECISION PUNCH
Core 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 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 pins are also used for part ejection from a die.
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.
