The progressive stamping die
When creating a metal object, it’s never as simple as cutting up with a pair of scissors and hoping it fits. If you really want to have a metal part that is consistent and precise, you need to get a metal stamping die. The progressive stamping die is a series of steps a piece of metal goes through before it can be considered ready for release. For instance, when you look at a soda can, there is that lift tab you need to pull to open the can. This tab is a fine example of progressive stamping die product. The tab has to fit precisely with the rest of the soda can lid or the tab won’t work.

The main processes that go through the progressive stamping method are coining, punching, and bending. It like feeding a sheet of metal into a series of stations before it comes out as a finished part. There can be many problems in every step which is why it is important to find the kind of company that will not accept mediocre work or work ethics. A simple miscalculation on the software design will put the finished off by a millimeter. Unfortunately, that miscalculation can cost a company hundreds of millions of dollars because of wasted time and metal sheets.
In the world, there are very few countries whose orientation is for zero errors. One of these countries is Japan. This is why metal works in Japan is a hotly pursued industry. Companies from all over the world troop to Japan’s metal works companies hoping to minimize costs by getting their parts right at first go. Provided they choose wisely, 99% of the time they get the part they order exactly how they want it. The companies then save money and get their products out as scheduled.
