Multi-station Bolt Forming Machine

Bolt former selection starts with the finished component rather than the machine model.

Shinetop's STBF series is built around cold heading — a process that upsets, extrudes, and trims wire or rod into finished fastener shapes across multiple die stations. Depending on the selected tooling (3-die 3-blow or 4-die 4-blow) and forming sequence, the series covers:

Hex-Head Bolts

Standard hex-head bolts are the core application, especially on the Three Die Three Blow machine. Machine size should be matched to finished bolt diameter, total length, head geometry and required output.

Socket-Style Fasteners

Internal-hex (socket) fasteners are also within scope, alongside standard external-hex products — sizing and tooling adjust accordingly for the recessed drive shape.

Long-Shank Bolt Blanks

The larger STBF models handle finished lengths up to 355 mm, so the series covers both short standard fasteners and longer bolt components without switching machine families.

Hollow, Solid, and Special-Shaped Parts

Beyond standard bolts and screws, the same tooling logic extends to hollow parts, solid special-shaped components, and fasteners requiring extra upsetting or extrusion steps. For non-standard geometries, the forming process is best evaluated from the finished-part drawing.

For broader production planning beyond the bolt former itself, see Shengtuo's fastener manufacturing equipment solution.

A multi-station automatic bolt making machine forms the product progressively instead of attempting to create the complete geometry in one operation.

1. Wire Feeding

Wire is continuously supplied to the machine through the feeding system according to the required blank length.

2. Cut-Off

The material is cut into a controlled blank before forming. Different STBF models provide different maximum cut-off diameters and cut-off lengths.

3. Sequential Cold Forming

The blank moves between forming stations through the transfer system. Each die and punch performs part of the required forming sequence.

A 3-die machine provides three forming stations, while a 4-die machine provides four.

4. Final Bolt Geometry

After the required forming operations have been completed, the component leaves the forming section as a bolt blank or formed fastener component.

5. Thread Rolling Where Required

When the finished bolt requires an external thread, thread rolling can follow the cold-forming operation as a separate production stage.

This combination of cold forming and subsequent thread rolling is commonly used in fastener manufacturing because the forming and threading stages perform different functions.
