Cold forging is a metal forming process where a slug or blank is deformed at room temperature. Cold forged parts can be produced using one or more single station vertical mechanical or hydraulic presses, or automated multi-station cold forming machines where the pre-formed part is transferred from one station to the next at high speed with each station performing a specific cold forming process.
The cold forming processes do not cause any structural changes to the metal which maintains all its original mechanical and tensile characteristics. Cold forging is a very cost effective metal forming method for mass produced parts with respect to other forging methods.
Cold forging is an ideal option for those manufacturers who have a high-level demand on precision. Automobile manufacturers are the most typical consumers of cold forging product, and cold forging industry has been progressing with the prosperity of automobile industry.
Cold Forging Advantages (Vs hot forging)
- High productivityIncreased dimensional control
- Cost effective
- Improvement of mechanical properties
- Excellent dimensional accuracy and surface quality
Many different materials are available for cold forging as carbon steel, stainless steel, aluminium, zinc, brass, bronze…
Cold forging products are widely used by so many industries as electronics, household appliances, hardware, machinery, plumbing, telecom, automotive (pinions, barrels, solenoid bodies, plungers, cores, parts for car seats, alternators, parts for switches, valves, antivibration parts, spiders, inner racks, parts for flywheel magnetos, hollow parts with stems and shafts, etc)
