Overviewofstampingdie

Stampingdie-inthecoldstamping,material（metalornon-metallic）processedintoparts（orsemi-finished）aspecialprocessequipment,calledcoldstampingdie（commonlyknownascolddie）.Punching-isatroomtemperature,theuseofamoldmountedonthepresstoexertpressureonthematerial,toproduceaseparationorplasticdeformation,therebyobtainingapressureprocessingmethodoftherequiredparts.
