This document discusses three types of cold forming processes: wire drawing reduces the cross-section of wire by pulling it through drawing dies, deep drawing forms sheet metal into 3D shapes like cups using dies, and cold rolling provides sheet, strip and foil with good finishes and strength by rolling metals through mills.

1. COLD FORMING PROCESS

2. TYPES OF COLD FORMING PROCESS
• Wire drawing process
• Deep drawing process
• Cold rolling

3. WIRE DRAWING PROCESS
• Wire drawing process is the process to reduce
the cross-section of a wire by pulling the wire
through a single , or series of , drawing die(s)

5. DEEP DRAWING PROCESS
• A manufacturing process that is used in the
forming of sheet metal into 3D cup or box or
any desired shape
• Common shape used in the deep drawing are
circle and square

7. COLD ROLLING
• The cold-rolling of metals has played a major role in industry
by providing sheet, strip, foil with good surface finishes and
increased mechanical strength with close control of product
dimensions

8. Rolling mills

9. Shaped rolling or section rolling
• A variety of sections can be produced by roll forming process
using a series of forming rollers in a continuous method to roll
the metal sheet to a specific shape
