H13 Steel Ejector Pins are critical die casting mold components used in the mold ejection system to remove solidified metal castings from the mold cavity after each casting cycle. These pins push the finished casting out of the mold while maintaining part integrity and preventing deformation.

Manufactured from high-quality H13 hot-work tool steel, ejector pins offer excellent resistance to heat, wear, and thermal fatigue. Their durability allows them to operate reliably under the extreme temperatures and high pressures found in aluminum, zinc, and magnesium die casting processes.

With precision machining and strict quality control, our ejector pins ensure stable mold operation and consistent demolding performance in high-volume die casting production.

Ejector pins play a vital role in the die casting mold ejection system. After molten metal fills the mold cavity and solidifies, the mold opens and the ejector system activates. Ejector pins then push the casting out of the cavity so the next cycle can begin.

Because ejector pins are exposed to repeated thermal shock and mechanical force, they must maintain high strength, wear resistance, and dimensional stability.

Our H13 steel ejector pins are produced through precision CNC machining, grinding, and professional heat treatment processes to ensure long service life and reliable performance.
