Ejector Pins
Also known as knockout and forged pins, use these pins to push parts out of molds. Pins are precision-ground to tight tolerances and hardened for strength and wear resistance. Machining is not recommended.
H13 tool steel pins resist rapid changes in temperature.
Metric pins meet DIN 1530 specifications.

Through-Hardened Ejector Pins
Compared to standard ejector pins, these pins are less likely to chip and crack when used to push steel parts out of molds because they've been hardened through their core. However, they cannot be drilled or tapped and are more brittle than standard ejector pins. They're also known as knockout and forged pins. Made of H13 tool steel, they resist rapid changes in temperature. They’re precision ground to tight tolerances.

Oversized Ejector Pins
To fit in holes that have widened from wear and are too big for standard ejector pins, these pins are oversized. Also known as knockout and forged pins, they’re used to push parts out of molds. These pins are H13 tool steel, so they resist rapid changes in temperature. They’re hardened for strength and wear resistance and precision ground to tight tolerances. Machining is not recommended.

Shoulder-Style Ejector Pins
A thick shoulder underneath the head makes these pins more rigid than standard ejector pins. Also known as knockout and forged pins, use them to push parts out of molds. They're precision-ground to tight tolerances and hardened for strength and wear resistance. Machining is not recommended.
Pins are made of H13 tool steel to resist rapid changes in temperature.

Ejector Sleeves
Use these sleeves with mold pins to form holes, bosses, and other features in parts, and then push the parts out of the mold. Made from H13 tool steel, these sleeves are strong, hard, and resist wear. They've been surface hardened with a process called nitriding, which adds even more strength and wear resistance. They’re precision ground to tight tolerances. Machining is not recommended.
