Blanking and Piercing

useful processes for producing identical small metal parts such as washers, for use with nuts and bolts

What is A

Blanking punch

What is B

piercing punch

Presswork

Shaping sheet metal by pressing it with a hydraulic ram gives a rigid and tough shell structure

Extrusion

A hydraulic ram forces the heated metal through a shaped hole in a die

cold rolling

process in which a flat strip of metal is passed through a series of rollers that progressively change it into its final shape. Each set of rollers alters the shape a little bit

Die casting

Large scale casting that has a die that can be opened and closed, and molten metal can be poured in.

Investing casting

Very accurate casting for small items that use wax as the pattern and then covered in investment plaster. The plaster is then put into an over so the wax would drip out.
