H13 Steel Long Ejector Pins for Deep Die Casting Molds
Specialized die casting mold components designed for deep cavity molds where standard ejector pins cannot reach the casting surface. These extra-length pins are essential for the ejection system of high-pressure die casting molds to safely remove metal castings from deep or narrow mold cavities.
Product Overview
Manufactured from H13 hot-work tool steel, long ejector pins provide excellent resistance to high temperatures, thermal fatigue, and mechanical stress. Their long and slender structure allows precise force transmission while maintaining stability during repeated casting cycles.
These ejector pins are commonly used in aluminum, zinc, and magnesium die casting molds, particularly in molds that produce deep structural parts or components with extended internal cavities.
