Metal Stamping in Industry: Evolution, Precision, and Applications

Metal stamping
An essential part of industrial manufacturing, metal stamping has seen a dramatic evolution, an excellent instance of precision engineering that has broadened its applications across a number of industries. The practice of metal stamping is very old. In fact, it is historically linked to the art of sign making. For centuries, and indeed millennia, the process of manually stamping symbols onto metal for industrial purposes went largely unchanged. But over this same huge span of time, technological innovation worked its magic, revolutionizing metal stamping first by introducing mechanization and later by means of sophisticated, highly automated systems.
Metal stamping is all about precision. It uses high-speed presses, progressive dies, and computer-controlled systems to achieve the precision found in the finest watches—indeed, to push the accuracy envelope even further, so that it’s not even fair to compare the precision of metal stamping to that of watchmaking. Metal stamping’s evolution from mostly manual operations to computer-aided design has catapulted it not just to the top of the accuracy ladder but also to the capability of doing really intricate work. And because it can do so with such consistent quality, it’s met the demands of industry after industry, where precision is job one, and “thou shalt not deviate” is the only rule governing the operation. Metal stamping is versatile and, across most sectors, is indispensable.
The pushes and prods of modern manufacturing are still metal stamping's best friends, but they are not the only ones. Count the advances in materials and technologies as pushing on metal stamping's behalf. High-strength alloys, lightweight materials, and exotic metals are now stampable. These materials are offering enhanced performance in demanding applications. In many ways, they are the demanding applications. Then count on progressive die designs and simulation software to do the same for stamping efficiency. Those are the low-counter figures; the high ones come from considering what makes a smart factory smart. Use the Internet of Things in a stamping tool, and you can know what's going on inside it at any moment. From that, tool life can be predicted pretty well.
The future of metal stamping is profoundly connected to sustainability, which has, for some time now, been guiding the manufacturing process toward environmentally conscious practices. "The journey is long and winding," says Roshandel, "but it is leading to the sustainable metal stamping shop with greener technology, a well-implemented recycling program, and the use of more ecologically sound materials."

Roshandel goes on to identify another key component of the future of stamping: the unerring lean production methodologies, pursued by the global manufacturers that depend on the stamping process to yield high volumes of parts at low cost while maintaining quality. Lean practices coupled with the idea of zero-defect manufacturing—essentially an idea that arose out of total quality management principles—are continuously improved by smart, driven people in the metal stamping world.
