Stamping Design Guidelines Jonathan Zhang Stamping Design Guidelines Jonathan Zhang 1 Stamping Design Guidelines Jonathan Zhang Stamping Design Guideline Stamping includes a variety of sheet-metal forming manufacturing processes using a machine press or stamping press, the processes including punching, blanking, embossing, bending, forming, drawing, flanging, and coining. This could be a single stage operation where every stroke of the press create the desired form on the sheet metal part, or could occur through a series of stages. Stamping is an economical way to form metal components with variety of characteristics including strength, durability, and wear resistance. Also they will have good conductive properties and stability. The purpose of this design guideline is to provide some basic design concepts which could optimize all the features that a metal stamping process offers. 1. Material Selection Over-specifying a steel grade and blank thickness are major factors to drive up the cost of metal stamping. There are many choices of sheet and strip materials that will respond well to metal stamping and forming processes. However, the price and availability can vary in a wide range, so it has significant impact on the cost and delivery of production. The following are some key factors that should take into consideration when selecting the material and specifying physical characteristics of the material. Material Properties There are many different ferrous and non-ferrous alloys available with different stock thicknesses and tolerances. The non-common alloys will be custom-produced by the steel mills, and th
