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.
durability, tolerance and tensile strength. Ejector pins can be made with a variety of treatments, which
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.
hard throughout their diameter. They are often used for injection moulding of plastics and can be used in
cooler moulding environments below 200°C.
tapped. They can be used at temperatures above 200°C and are quite durable. They can chip when
compared to through hardened pins but have a greater life expectancy at higher temperatures.
environments. They can be used at temperatures from about 600-1000°C. These ejector pins have a self
lubricating surface coating that allows them to be used at these high temperatures.
protect them and make them more durable. These coatings work by reducing friction so that the pins
become more wear resistant and the ejection of the part becomes more consistent.
