Definition: A stripper plate is a component used in metal fabrication and tooling moulds. It is designed to strip the workpiece or part from the punch and may also guide the stock by holding the workpiece down during a press operation. It is sometimes referred to as a pressure plate 1.
Applications: Stripper plates are commonly used in moulds for ejecting moulded parts, especially in complex geometries or moulds with undercuts. They ensure smooth ejection and preserve the integrity of delicate parts 4.
Materials and Specifications: Stripper plates can be made from materials like A-36 carbon steel, which is stress-relieved and precision-ground. Typical specifications include ground top and bottom surfaces with tight tolerances (e.g., +/- .003 on the top and bottom, +/- .005 on the edges)
