H13 Steel Ejector Pins with Nitriding Surface Treatment and 44-46HRC Hardness for Die Casting Mold Components

Critical die casting mold components used to safely eject solidified metal parts from the mold cavity after the casting cycle is completed. These precision pins ensure smooth and controlled part release while maintaining the integrity of the cast component.

Manufactured from high-performance H13 hot-work tool steel, these ejector pins are designed to withstand extreme operating conditions such as high temperature, pressure, and repeated thermal cycling found in die casting processes. Their excellent heat resistance and wear resistance make them ideal for long-term use in aluminum, zinc, and magnesium die casting molds.

With high machining precision and durable material properties, H13 ejector pins help improve mold reliability, reduce downtime, and maintain consistent casting quality in industrial production.
