H13 Material Polished Core Pins with 0.003mm Tolerance for Medical Syringe Injection Molding
A mold core pin is an extension or projection of the mold that forms the inner surface used in plastic injection molding, commonly employed in the medical industry. This specialized core pin is designed for injection molding medical pipettes for fluid sampling. Our manufacturing tolerance reaches 0.003mm, and the core pin requires specific toughness to withstand dislocation during the molding process without breaking. The successful application of mold core pins largely depends on the precision grinding process.
