An Ejector Pin is a pin that is used in the injection molding industry to push the final molded product out of the mold. They are used forcefully to eject the solid part out of the mold and are usually made of high-quality steel. They are also known as knockout pins, knock-out pins or KO pins. They are an integral component of the ejection system in mold, which determines the final outcome of products in an injection molding process. The element applies some force to eject a crucial part from the actual mold. The Ejector Pin is very efficient and useful.
