Application
the plastics, automotive, aeromotive and medical industries, amongst others. A blade shape is used when
there is only a small surface area on the finished part. They are also known as knockout pins, knock-out
pins or KO pins. When the mould is opened, the pins extend into the mould cavity, push the part out, and
then retract, allowing the mould to close and be refilled.

affect the hardness of the pin. By choosing the right ejector pin for the application, the lifespan and
durability of the pin will be enhanced.

cooler moulding environments below 200°C.
