Some Useful Knowledge About Metal Stamping Process

Today, manufacturing has embraced a wide range of advanced technologies that have enabled the reduction of turnaround time considerably. As a result, demand on the metal stamping industry has also increased as the components have to be made to be exactly suitable to the final product. This has made precision and custom metal stamping much more important in the manufacturing industry.

Custom metal stamping is the process of creating metal products according to the required sizes and shapes through a method called stamping. It involves the pressing or stamping of the metal in dies or press tools to give it the right shape. In custom metal stamping, the final products are made according to customer's precise requirements and conditions. Custom metal stamping is used in various industries like construction, electrical, bearing, automotive, medical and janitorial, among others.

Metal stamping typically involves the normal process of metal stamping but with certain changes. These can be the change in the kind of metal to be used, changes in the size and shape of the final product, the need to produce many kinds of sizes and shapes, high quality of the tools used, the volume and the number of units to be produced, the kinds of presses required and the number of presses and dies required. Some producers are changing their processes to accommodate any volume, up to thousands of tons.

This technique is an ancient one and it has been used in the olden days for the purpose of making weapons from metals. It did not take people of the olden days a very long time to figure out that metal could be shaped the way they wanted it.

Today, there are computers and as a result the whole process has become automated. Also, the designs that are required are mostly formed on the computer and these are done by product developers.

Have no doubt about it at all that Metal Pressings Is the Most Important Technique to Manufacture Metal Components

A shallow or deep press tool is used for the process, but this depends on the thickness of the metal sheet. There are many industries that have to manufacture products in large quantities and as such, to keep the manufacturing process economical, the metal pressings have to be run all the time, without any stoppage.

This kind of process of metal pressings is also used to manufacture metal components used in airplanes and rockets. To press these metals, manufacturers make use of mostly hydraulic machines. This is mainly because this kind of a machine can cut, form, and shape the metal – in just one single process.

There are three main components in sheet metal stamping -- the die, the punch and the binder/blank holder. The sheet is kept between the blank holder and the die and the punch is driven into the die wherein the sheet spreads over the die because of the drawing and stretching. The blank holder provides the restraining force that is required to control the sheet flow into the die. This force prevents wrinkling and tearing of the sheet as the quantity of material going into the machine can be controlled. For some processes where the blank holder force is too high for the material, draw beads are used to create the restraining force.
