subject: What Exactly Is Metal Stamping? [print this page] Metal Stamping involves a number of sheet-metal forming manufacturing processes and is carried out by a machine press or stamping press. The various processes included in Metal Stamping are blanking, bending, punching, embossing, drawing, forming, coining and flanging. Metal Stamping may be a single stage operation and at times, it may involve a series of stages.
What is more important is that, Metal Stamping is one of the most economical ways for forming metal components with different characteristics like durability, strength and wear resistance. This process or rather series of processes yields components that are attributed with high stability and good conductive properties.
Stamping Processes
Stamping Processes involve four major operations- blanking, piercing, forming, and drawing. All these operations are performed using Stamping Equipment that can be classified into two sets namely Mechanical Presses and Hydraulic Presses. A brief description of major Stamping Processes is as follows.
Blanking- In this process the roll stock of sheet metal is cut to size.
Piercing-This is the process by which internal features such as holes and slots are made in the stock.
Forming-It is a linear process that is carried out by up and down movement of the press equipment. The process is used to generate complex shapes.
Drawing-The degree of deformation governs whether drawing will be shallow or deep.
After passing through so many processing stages, the finished piece develops several tooling marks. A number of other operations such as graining are performed to remove surface defects and achieve final finish. So, it can be said that Metal Stamping is a series of processes that transform a crude piece of metal into practically applicable forms of metal sheets.
Material Selection
Material Selection is a very crucial beginning that will determine the course of the whole Metal Stamping process. One can come across different choices of strip and sheet materials that can respond well to Metal Stamping processes. The price and availability varies a lot which in turn directly affect the delivery and cost of the production.
