High-Precision 4 Die 8 Blow Cold Heading Machine | Multi-Station Cold Former
Advanced 4 Die 8 Blow Cold Forming Technology for Complex Fasteners
The FMT 4 die 8 blow cold heading machine is a premier multi-station solution engineered for high-precision cold forming. This advanced equipment is specifically designed to handle complex metal components that require multiple shaping stages. By utilizing a '4 die 8 blow' configuration, the machine provides the versatility to perform up to eight distinct strikes across four die sets, allowing for intricate operations such as extrusion, trimming, and multi-stage heading on a single workpiece.
Whether you are sourcing from China’s leading manufacturing hubs or seeking Taiwan-standard precision, FMT’s progressive headers ensure exceptional tolerance control. This machine is the industry standard for producing specialized fasteners, including semi-tubular and fully tubular parts, custom nuts, and high-strength bolts that traditional machines cannot handle.

The Cold Heading Process: How the 4 Die 8 Blow Machine Operates
Operating a multi-station cold heading machine requires a synergy of mechanical power and precision setup. The FMT 4-die 8-blow process follows these professional steps:
- Technical Setup: Selection of high-grade tungsten carbide dies and precise adjustment of the stroke length.
- Precision Wire Feeding: Raw metal wire is fed through a straightening mechanism into the cutoff station.
- Sequential Forming: The material travels through four stations. With two blows per die, the workpiece undergoes gradual deformation, reducing stress on the material while achieving complex geometries.
- Trimming & Extrusion: Integrated stations allow for simultaneous trimming of heads or deep extrusion of tubular shanks.
- Automated Ejection: Finished parts are safely ejected via the PKO system onto a conveyor, ensuring zero damage to the threads or surface finish.
