Ejector Pins vs Punches: Unraveling Their Differences
Function
Ejector pins are heroes of plastic injection molding. When melted plastic hardens in the mold, they push the new plastic products out smoothly, like a gentle usher.
Punches are heavy – hitters. They work with presses to punch holes or cut shapes in materials such as metal sheets. For metal brackets, punches make holes for assembly.
Ejector pins are simple, long, thin cylinders. One end attaches to the mold’s ejection system, and the other end has different shapes. A round tip suits general use, a flat tip for flat – surface products, and a tapered tip for delicate items.
Punches have a versatile design. Their working end can be round, square, or custom – shaped. It’s made of super – hard materials to endure high – pressure stamping.
Application
Ejector pins are crucial in plastic production, used for plastic toys, electronics, and consumer goods.
Punches are essential in sheet metal, automotive, and hardware production, creating metal components from small washers to large car parts.
