Similar to stamping sheet metal punching uses heavy machinery and a punch and die assembly to put holes or indents into pieces of sheet metal. A process done by welding binding with adhesives and bending in the form of a crimped seam. Appliance engineers have several options for joining sheet metal including screws rivets welding bonding clinching and folding. Which is best depends on the material its thickness and the application requirements.

A common method of self locating parts in machine assemblies is to use dowel pins which can then either be used strictly as a locating feature to hold parts in the correct place during assembly with screws or can be used on their own for press fit assembly.
