Ejector pin size is typically defined by the pin diameter, overall length, head dimensions, and tip geometry. The correct size depends on the molded part geometry, required ejection force, available space in the mold, ejector plate design, and required fit and clearance. Ejector pins are available in different metric and […]

If you design or maintain injection molds, you need to know the main ejector pin types and when each one works best. This page provides a clear selection guide to help you match the right pin type to your part geometry and ejection requirements. Quick Answer: Straight ejector pins are
Choosing an ejector pin material is not about picking the hardest option. It’s about matching hardness, toughness, and wear resistance to the specific pin diameter, length, resin, and production volume. The right material keeps the pin from bending, breaking, or wearing too quickly. For most molds, start with SKD61. If

If you design or maintain injection molds, you’ve probably faced this problem: The part has a small rib, boss, or narrow feature, and a standard straight ejector pin won’t fit. You could reduce the whole pin diameter, but then it bends during ejection. That’s exactly when a step ejector pin
Which Ejection Method Is Better for Injection Molding? Choosing the Right Ejection Solution for Injection Mold Design In injection molding, part ejection is not only about removing the molded part from the cavity. The right ejection method directly affects: Part surface quality Mold reliability Production efficiency Tool maintenance cost For
