A Cold-forged header machine, also called a cold heading machine or Bolt header machine, is a high-speed industrial machine used to manufacture bolts, screws, rivets, pins, and other fasteners from metal wire or rod.
How it works
Wire/Rod → Cutting → Heading/Forming → Multi-stage Forging → Finished Blank
- Wire feeding – Metal wire is continuously fed into the machine.
- Cutting – The wire is cut into precise lengths called blanks.
- Cold heading – Powerful punches force the blank into dies.
- Forming – The material is progressively shaped into the required bolt or fastener head.
- Output – The formed bolt blank is discharged for further operations such as thread rolling, trimming, or finishing.
Main advantages
- High production speed
- Excellent dimensional consistency
- Stronger parts due to cold-working
- Reduced material waste
- Suitable for mass production
- Produces uniform bolt and fastener heads
- Can perform multiple forming operations in one machine
Common applications
Cold-forged header machines are widely used for manufacturing fasteners for:
Automotive • Tractors • Construction • Railway • Electrical equipment • Industrial machinery • General engineering
In simple terms, a cold-forged header machine converts metal wire into accurately formed bolt and fastener blanks without heating the metal.
