Sheet metal forming processes are those in which force is applied to a piece of sheet metal to modify its geometry rather than remove any material. The applied force stresses the metal beyond its yield strength, causing the material to plastically deform, but not to fail. By doing so, the sheet can be bent or stretched into a variety of complex shapes.

The development of high pressure molding using flasks, took place in the USA in the mid 195O's. These handling systems were a natural progression away from heavy manual labor, and the reliance on labor to meet production targets. The IN-LINE arrangement is a single line arrangement, which runs parallel to a mould conveyor.
It is important to note that the PVD process is a line of sight process, which may limit the ability to coat interior contours and features. For these applications, nitriding, which case-hardens all exposed surfaces, is recommended. Below is a list of standard surface treatments offered by Precision Punch & Tooling.

Die-cutting is a fabrication process that uses specialized machines and tools to convert stock material by cutting, forming, and shearing. In printing, die cuts are used to create custom shapes and designs for labels. It starts with a part called, unsurprisingly, a die. A manufactured die is a specialized piece of metal tooling used to cut a ...
Punch presses are commonly used for punching processes. The punch force is in the several tens of tons class and is primarily used to form sheet materials. Punch presses that punch out sheet material with dies attached to a tool holder—called a turret—is known as a turret punch press.

The process of injection compression molding combines the advantages of an injection step and a following compression step, which eliminates the disadvantages obtained by long flow paths (Fig. 2.10).First, a volume of polymer melt corresponding to the volume of the molded part is injected into a mold that is not completely closed.
clean off any debris from the metal cutting because even the minute chard getting under the press would damage the metal. After that, the blank are put into a 200 tons press containing a forming tool. The powerful press forces the metal and then punches out the shape of the finish frying pans. The freshly formed aluminum frying pans fall onto the conveyer below.
