Metal Pressing

Stamping presses and stamping dies are tools designed to make large-scale sheet metal parts. All of these parts accomplish their shape through the results of the die tooling.

Production stamping is usually undertaken on materials .020” to .080” thick, but the procedure can also be applied to foils as delicate as .001” as well as to plate stock with thickness' approaching 1.000”.

Formability is the main function of sheet metal material. Formability is more considered as the components capability to be:

• bent
• extended
• pulled

The metallurgical phrase for such properties is ‘ductility’. Ductility is the substances capability to distort and lengthen without ever rupture. The degree by which a stamping is afflicted by such deformation is straightly related to the part’s total shape and geometry. Additional factors also effect the material’s formability.

Some of them are:

• the die design
• the press
• the press speed
• lubrication
• sheet metal feeding mechanisms
• monitoring and control systems

The term ‘die’ is basically a standard phrase used to illustrate the tooling designed to create stamped pieces. A die set assembly consisting of a male and female element is the specific tool that creates the shaped stamping. The male and female components function in contrast to both form and punch holes in the stock. The upper half of the die set, which might be either the male or female, is attached to the press ram and delivers the stroke action. The lower half attaches to an intermediate bolster plate and this action is fastened into the press bed. Guide pins are used to make sure alignment between the top and bottom halves of the die set.
