Injection molding holding pressure often called packing pressure, is a critical parameter in the injection molding process. When the mold cavity is approximately 95% filled, the injection pressure translates into the holding pressure. The holding pressure is typically lower than the injection pressure. This pressure helps to ensure that the molded part maintains its shape […]
