Process

Formingmetal on a bend press a main feature of sheet metal is its ability to be formedand shaped by a variety of processes. Each process does something different tothe metal giving it a different shape or size.

Stretching
Stretching isa process where sheet metal is clamped around its edges and stretched over a dieor form block. This process is mainly used for the manufacture of aircraftwings, automotive door and window panels.

Drawing
Drawing forms sheet metal into cylindrical or box shapedparts by using a punch which presses the blank into a diecavity.

Deep Drawing
DeepDrawing is a type of drawing process where the depth of the part is greater thanits diameter. Deep drawing is used for making automotive fuel tanks, kitchensinks, 2 pieces aluminum cans, etc.

Cutting
Cutting sheet metal can be done various ways from handtools called tin snips up to very large powered shears. With the advances intechnology, sheet metal cutting has turned to computers for precisecutting.

ending and Flanging
Bending and flanging imparts stiffness to a sheet metalpart or to form various shapes, such as 3 piece aluminumcans.

punching and Shearing
During punching or shearing, the sheet metal is cut byusing a punch and die.

Spinning
Spinning is used to make axis-symmetric parts byapplying a work piece to a rotating mandrel with the help of rollers or rigidtools. Spinning is used to make rocket motor casings and missile nose cones forexample.

Press Forming
This isa form of bending used for long and thin sheet metal parts.
