Metal Drawing Manufacturing Process

Powder Processes Metal Drawing Metal drawing is a manufacturing process that forms metal work stock by reducing its cross section. This is accomplished by forcing the work through a mold, (die), of smaller cross sectional area than the work. This process is very similar to metal extrusion, the difference being in the application of force.

What's the difference between dry printing and wet printing?

Two such terms, wet printing and dry printing, are the subject of this Refresher Course column, suggested by Linn's reader Bill Stahl. Wet printing and dry printing are terms used primarily in intaglio printing, which is also known as engraving, line engraving or recess printing. That is the method of production that involves a softened metal plate onto which a human engraver or a machine has

Machining Dry Is Worth A Try Modern Machine Shop

The workpiece's suitability for a dry process also depends on the material. A cutting fluid can be superfluous for cutting most alloys of cast iron, and carbon and alloyed steel, for example. These materials are relatively easy to machine and conduct heat well, allowing the chips to carry away most of the heat generated. The exception is low-carbon steel, which becomes more adhesive as the
