Fastener Manufacturing Equipment

Multi-Station Machine Range

3-, 4-, 5-, 6- and additional multi-station configurations allow customers to evaluate different forming requirements.

Broad Forming Capacity

Selected published series cover fastener sizes up to M30 and product lengths up to 355 mm.

In-House Machining Capability

Gantry machining, CNC machining, boring and inspection equipment support production of the machine structure and key components.

Custom Machine Capability

Shengtuo can evaluate non-standard forming equipment according to special customer requirements.

Cold Forming + Thread Rolling

Customers can evaluate both cold forming equipment and thread rolling machines for core fastener manufacturing stages.

Fastener production may involve several manufacturing stages, depending on the finished product and material. For cold-formed bolts and precision components, the core process normally includes material feeding, cut-off, multi-stage forming and, where required, thread rolling.

Shinetop focuses on the cold forming and thread rolling stages of this process.

This allows buyers to select equipment around the actual fastener manufacturing process instead of treating every machine as an isolated production unit.

One advantage of multi-station cold forming is its ability to produce more than one standard fastener shape.

Based on Shengtuo's existing machine range and displayed production samples, suitable applications can include:

Hex Bolts

Hex-head fasteners are one of the most important product categories for bolt forming equipment. Shengtuo's catalogue specifically includes HEX product size information across its bolt former series.

For manufacturers planning hex bolt production, machine selection should consider bolt diameter, total length, head geometry and required forming sequence.

This capability also supports a dedicated hex bolt making machine solution for buyers focusing specifically on hex bolt production.

Socket-Head Fasteners

The Shengtuo catalogue also lists socket-type fastener capability within the bolt former specifications.

Depending on the required geometry, different die and blow configurations can be evaluated.

Long-Shank Bolts and Components

Selected machine configurations support long workpieces, with product lengths reaching up to 355 mm on published 3-, 4- and 5-die series.

Special-Shaped Cold-Formed Parts

The actual production samples supplied by Shengtuo show a broad range of headed, stepped, hollow-looking, splined and special-profile components.

For these products, the forming sequence and tooling arrangement should be evaluated according to the finished drawing.

The following comparison provides a quick overview of Shengtuo's main fastener forming equipment. Exact specifications vary by model and should always be checked against the selected machine configuration.

Fastener manufacturing equipment must maintain stable feeding, cutting, transferring and forming during continuous operation.

Shengtuo's machine structure includes several features designed around these requirements.

Automatic Wire Feeding

Automatic straightening and feeding equipment helps move the wire into the forming machine continuously.

Adjustable Transfer System

Transfer fingers move blanks between forming stations. Shengtuo's displayed system allows individual adjustment of the transfer fingers to suit the forming setup.

Cut-Off and Feed-Length Control

The cut-off system controls the blank supplied to the forming stations, while applicable configurations use digital adjustment to control the feed length.

Pneumatic Components and Machine Control

Existing Shengtuo machine materials show pneumatic control components and branded pneumatic/solenoid components used in applicable configurations.

The performance of a cold forming machine depends not only on its nominal forming force or number of stations. The machining accuracy and stability of the machine structure are equally important.

Shengtuo uses a range of in-house machining and inspection equipment for machine production, including:

• Gantry machining equipment

• CNC machining centers

• High-precision inspection platforms

• CNC boring lathes

• Large lathes

• Five-side machining centers

For machine-bed processing, Shengtuo states that one-setup machining helps control machining accuracy within 0.05 mm.

This machining capability supports the alignment and structural consistency required for multi-station forming equipment.

There is no single fastener making machine that is automatically suitable for every bolt or cold-formed component.

Before selecting a machine, buyers should evaluate the following factors.

1. Finished Part Diameter

Check the final fastener diameter and required wire diameter against the forming capacity of the selected model.

2. Part Length

Longer fasteners require sufficient cut-off, feed and kick-out capacity.

3. Head and Part Geometry

A standard bolt head and a complex multi-step cold-formed component may require very different forming sequences.

4. Number of Forming Operations

The required forming operations help determine whether a 3-, 4-, 5-, 6- or other multi-station configuration is appropriate.

5. Material

Material properties influence forming load, tooling and achievable output.

6. Required Production Output

The required parts-per-minute target should be evaluated together with part geometry and material.

7. Thread Requirements

If the component requires external threads, the required thread diameter, length and specification should also be used to select the appropriate thread rolling machine.
