SKD61/SKD51 Material High Precision Mold Core Pins Ejector Pin 0.005 Tolerance
Core pins are essential components in plastic molding and die casting applications. These precision pins are fixed within plastic molds to create specific shapes in molded or cast parts. Unlike ejector pins that push finished parts from the mold, core pins form the actual part geometry during the molding process.
Manufactured from SKD61/SKD51 materials with high temperature resistance, these core pins undergo nitriding surface treatment for enhanced durability. They are ideal for creating tall, thin cores that might be too fragile if machined directly into the mold.
