Mold Core Pins, also called round pieces, are essential metal mold components. These pins, sometimes referred to as flat pins or sleeves, are primarily used for ejecting plastic parts from ribs and other complex geometries. When traditional ejection methods are unsuitable, core pins provide an effective solution for plastic mold operations. They are also known as flat thimble rods, pins, needles, or needle holders in various industry applications.
