Dinking -
A specialized form of piercing used for punching soft metals. A hollow punch, called a dinking die, with beveled, sharpened edges presses the sheet into a block of wood or soft metal.
Coining
Similar to embossing with the difference that similar or different impressions are obtained on both the sides of the sheet metal.
Deep Drawing
Deep drawing is a metal forming process in which sheet metal isstretched into the desired shape.
*A tool pushes downward on the sheet metal, forcing it into a die cavity in the shape of the desired part.
Strectch forming :-
Stretch forming is a metal forming process in which a piece of sheet metal is stretched and bent simultaneously over a die in order to form large bent parts.
Roll forming :-
Roll forming is a continuous bending operation in which a long strip of sheet metal is passed through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross section profile is obtained.
Roll forming is ideal for producing constant profile parts with long.
