High Precision Stavax Material Mold Core Pins Injection Molding Accessories With EDM For Cosmetic Or Medical Needles

Core pins are used in plastic molding and die casting dies. They are fixed elements that create voids to 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 from the bulk aluminum of the mold. The pins are also used for part ejection from a die.
