Ejector pins are vital in creating parts. They are an integral component of the ejection system in mold, which determines the final outcome of products in an injection molding process.
Injection molding is a manufacturing process that involves injecting molten plastic in a metal mold to assume the shape of the mold. Therefore, ejector pins injection molding involves the removal of completed parts from the die molds. The metal mold is made of two parts: A and B sides. Upon cooling of the molten material in the mold, both parts of the metal mold are separated to allow for the removal of the solid plastic. Injection molds are built such that when they are opened, the A-side half is lifted, leaving the formed part and the B-side.

Ejector pins are located on the B-side half of a mold, from which they push the formed part out of the mold. The pin mark of an ejector mold is commonly imprinted on finished products as a dent.

There are many types of ejector pins used in product manufacturing. Below are the commonest types you will find ideal for the process.

These ejector pins are heat-treated to ensure consistency in the hardness through the diameter of the pin. Through-hard pins can withstand working temperatures up to 200°C, and it is mostly suitable for plastic ejection system in mold.

They are also known as Nitride H13 pins, are much harder pins than the through hard pins, and are suitable for die casting ejection systems in mold. Case hardened pins are nitrated to 65 – 70 HRC and can withstand temperatures above 200°C.

Manufacturers developed these ejector pins because of the inability of the Nitride H13 pins to be employed in working temperatures above 600°C. The black ejector pin is coated with a black surface treatment which allows it to be self-lubricating and withstand high temperatures up to 1000°C. It is an expensive ejector pin and is suitable for a metal ejection system in the mold for automobiles.
