Purchase Ejector Pins Today With DME


Ejector pins are used in plastics injection molds to eject or push the plastic part from the mold. There are many types of ejector pins, including different materials, sizes, tolerances and coatings, based on the injection mold base application. DME offers high quality ejector pins in all different sizing formats including Imperial, DIN & JIS standards. Our high quality pins are made from premium H-13 steel. We carry straight, shouldered, keyed ejector pins, return pins, sprue puller pins, ejector sleeves & sleeve extensions, ejector blades, core pins & retainers & more!
Made from premium H-13 steel • Core hardness 47-52 HRC minimizes bending • Non-chipping surface treatment alleviates flashing and minimizes nicking & dishing - 65-70 HRC • Annealed and finished heads permit easy machining • Centerless ground D diameter • Final finish minimizes wear and prolongs pin life
