H13 Steel Round Head Ejector Pins for Die Casting Molds
H13 Steel Round Head Ejector Pins are specialized die casting mold components used in the mold ejection system to remove solidified metal parts from the mold cavity after each casting cycle.
Product Overview
The round head structure provides stable positioning within the ejector plate and ensures consistent force transmission during the demolding process. Manufactured from H13 hot-work tool steel, these ejector pins offer excellent resistance to high temperature, thermal fatigue, and mechanical wear.
They are widely used in aluminum, zinc, and magnesium die casting molds, where reliable ejection performance is essential for maintaining stable production cycles. With precision machining and strict quality inspection, our round head ejector pins are designed to support accurate mold operation and long service life in high-pressure die casting environments.
