H13 Steel Core Pins for Die Casting Molds
Critical die casting mold components used to form internal holes, recesses, and complex internal geometries in metal cast parts. Installed inside the mold cavity, core pins create accurate internal features while maintaining dimensional stability during high-pressure die casting cycles.
Product Overview
Manufactured from premium H13 hot-work tool steel, these core pins are designed to withstand extreme temperatures, repeated thermal cycling, and high injection pressures commonly found in aluminum, zinc, and magnesium die casting processes.
With high hardness, excellent thermal fatigue resistance, and precision machining, H13 core pins are widely used in high-pressure die casting (HPDC) molds to ensure consistent part quality and extended mold service life.
