Core pins are essential components in plastic molding and die casting dies. They create voids to form desired shapes in molded or cast parts. Steel core pins are particularly useful in aluminum molds for creating tall, thin cores that would be too fragile if machined directly from aluminum. These pins also facilitate part ejection from dies.
