1. Curled edge
Sheet metal typically contains sharp edges with "burrs" after initial production. Curling is a forming process that involves deburring metal plates to produce smooth edges.
2. Bending
Another common sheet metal forming process is bending. Companies typically use brake presses or similar machines to bend sheet metal.
3. Ironing
Metal plates can also be ironed to achieve uniform thickness. For example, most aluminum cans are made of ironed aluminum. In its original state, the aluminum plate is too thick for beverage cans, so it needs to be ironed to obtain thinner and more uniform ingredients
4. Laser cutting
In recent years, laser cutting has become an increasingly common sheet metal forming process. Through laser cutting, the metal plate is exposed to high-energy laser and holes are burned on the metal.
5. Hydraulic forming
A little-known sheet metal forming process is hydraulic forming. Like deep drawing, hydraulic forming involves stretching the blank on the mold. So, what is the difference between hydraulic forming and deep drawing? The main difference between these two processes is that deep drawing requires multiple reductions in drawing, while hydraulic forming can be completed in just one step.
6. Punching
Finally, stamping is a sheet metal forming process that involves using punches and molds to drill holes in the sheet metal. The sheet metal is placed between the punch and the mold. Next, the punch is pressed down and passed through the metal plate to form a hole.
