What are ejector pins?

Ejector pins are used in the injection moulding process of the manufacturing of plastic kits and die cast kits. They apply force to eject the part from the mould: once it has been opened, the pins extend in to the mould and push the part out. They then reseat themselves to allow the mould to close and be refilled for the next one. These pins are also known as knock out pins.

They sometimes leave marks on models.

If the mark would be visible on the finished model, simply fill it with model filler. Another option, is to cover it with foil or a plastic strip.
