Where Can I Buy Ejector Pin In South Africa

Ejector Pins apply a force to eject a part from the mold, Since in some cases they can leave marks, it is important to give proper forethought to their pacement when designing a mould. Generally, ejector pins are located in the B-side mold half, the side in which the part will stay when the mold opens. Once the mold is opened, the pins extend into the mold cavity, push the part out, and then retract, allowing the mold to close and be refilled.

What is the ejector pin used for?

Ejector pins are used in plastic 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.

Where are ejector pins located?

They are located on the B-side of the mold, which is where the part stays once the mold opens. After the mold opens, the pins extend into the cavity of the mold, push the part out, and then retract so the mold can close and be refilled.

How does an ejector system work?

In a jet or ejector, a relatively high-pressure gas, like steam or air, expands through a nozzle. The steam or air converts that pressure or potential energy to velocity or kinetic energy. The jet of high-velocity steam or gas entrains the gas to be evacuated or pumped in the suction of the ejector.

What holds the heads of ejector pins in place?

An ejector retainer plate holds the heads of ejector pins in place. The main function of this plate is to lock the heads of the pins so they don’t come out during the injection molding process.
