H13 Steel Ejector Pins and Sleeves with 44-46HRC Hardness and ±0.01mm Tolerance for Die Casting Molds
H13 Steel Ejector Pins and Sleeves are essential die casting mold components used in the ejection system of high-pressure die casting molds. Their primary function is to push the solidified metal casting out of the mold cavity after the casting cycle is completed.
Manufactured from H13 hot-work tool steel, these ejector pins and sleeves are designed to withstand extreme heat, high injection pressure, and repeated production cycles. They provide excellent resistance to wear, thermal fatigue, and deformation, ensuring reliable mold performance and long service life.
With precision machining and strict quality control, our ejector pins and sleeves are suitable for aluminum, zinc, and magnesium die casting molds, supporting stable demolding and consistent production efficiency.
Ejector pins and ejector sleeves are key parts of the die casting mold ejection system. After molten metal solidifies inside the mold cavity, the ejection system activates to release the finished casting. Ejector pins push the casting out directly, while ejector sleeves are used when ejection is required around a core pin or cylindrical feature.
Our H13 steel ejector pins and sleeves are manufactured using precision CNC machining, grinding, and professional heat treatment processes to ensure high dimensional accuracy and stable mechanical performance.
