H13 Steel Ejector Pins for Die Casting Molds
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.
Product Overview
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.
