Towards the end of the 1900s, increasing awareness of the human impact on our planet sped up the search for ways to reduce our energy use. This was most apparent in the automotive parts industry. Safety regulations became stricter. People increasingly want cars that are more environmentally friendly and that operate more cost effectively. Advanced high strength steels developed for the automotive industry are changing the way cars are made.
Steel versus Aluminium
There is constant debate in the automotive industry about whether to use aluminium or steel in the production of automotive parts. Essentially this is a quest for finding material strong enough to be safe for use in automobiles that is formable and cost effective. Most of the top car manufacturers are opting for decisions of which material to be used being made on a part by part basis.
History of Die Stamping
Dating back to 2000BC, with stone-age man Junkyards near me beating iron with a hammer to make tools with heated metal resting on a bed or bolster, the idea of stamping metals is not new. Die stamping was first used to produce bicycle parts in the 1890s. Although die stamping produced parts with less durability than traditional forging, there was advantage in using machines to manufacture automotive parts more quickly. As demand for motor vehicles grew, faster production methods were welcomed.
A variety of metalworking methods are incorporated into the die stamping manufacture of automotive parts. Beginning with simple methods like bending the metal along straight lines, there are nine other ways machines are working with metal during the stamping process. Flanging, embossing, blanking, coining, deep drawing, stretching, ironing, curling and hemming each allow progressively more detailed parts to be made.
