Metal stamping has been used since very early times to not only create surface shapes on metals but to form the metal into very precise shapes. New technology and high tonnage presses allow for precision metal stamping with high production volume rates, low waste, and very reasonable cost.
The process of deep draw stamping is a specific process that uses forming die. These die are deeper in design than their diameter, which is where the “deep drawn” term comes into the process. To complete these deep designs, the action of the punch has to be very specific and precise, and there is also the need to carefully calculate the pressure required for shapes formed with extremely high tolerances.
While some parts are made through deep drawing with just one die, more complex shapes can be created using a progressive series of die to produce the end shape. With CNC technology, this is a fast, precise, and every accurate process with no need for additional finishing processes after stamping is complete.
Metals and Materials
Most machining services Offering deep draw stamping work with the softer and more malleable metals and alloys such as brass and copper as well as specific grades of aluminum.
The top companies and those specializing in the process can work with a full range of nonferrous as well as ferrous metals. This includes metals that have been galvanized and galvannealed, but also stainless steel and both cold and hot rolled steel.
Industries
Stamping is used in many different industries as a preferred way to manufacture both simple as well as complex metal parts. Parts and components made by deep draw stamping can be easily found in the automotive, aerospace, military and defense, as well as equipment manufacturing and shipbuilding industries.
Smaller parts and components used in electronics, lighting, food, and beverage production systems and in most types of appliances used in households and commercial industries are also made using this process.
