Automatic High-Speed Low-Noise Bolt Nut Screw Making Machines

These systems are designed to produce cold-headed fasteners and rolled-thread parts such as bolts, screws, nuts and similar pin-type parts (often called nails in the spec). Production size capability depends on the selected model and tooling.

The product line includes Cold Heading Machines and Thread Rolling Machines with multiple model variants. Cold heading variants cover nail/rod diameters from about 2.0 to 5.0 mm and lengths from 10 to 100 mm, with capacities from ~80 to 180 pcs/min. Thread rolling variants cover diameters roughly 2.0–5.0 mm and lengths 10–100 mm, with capacities up to 280 pcs/min. Motor power options are typically 3 kW or 4 kW depending on model.

Cold heading machines in this line typically run from about 80 up to 180 pcs/min depending on model and part geometry. Thread rolling machines can reach up to about 280 pcs/min for smaller parts, with other models in the 100–120 pcs/min range. Actual throughput depends on part size, material and tooling.

Across the available variants the machines handle wire/rod diameters roughly from 2.0 mm up to 5.0 mm. Finished part lengths shown in the specifications range from about 10 mm up to 100 mm depending on the model.

Typical motor power for the models shown is 3 kW or 4 kW. Final electrical specifications (voltage, phase, frequency) depend on the chosen configuration—please confirm required supply with the manufacturer or supplier.

Dimensions vary by model. Examples from the spec: Cold heading models include footprints such as 1.7×1.0×1.0 m (≈1000 kg), 2.0×1.0×1.0 m (≈1700 kg), 1.9×1.2×1.2 m (≈1700 kg) and 2.1×1.2×1.2 m (≈1900 kg). Thread rolling examples include 2.0×1.2×1.4 m (≈1000 kg) and 2.0×1.5×1.3 m (≈1500 kg).

The machines are engineered for reduced operating noise compared with older designs, but exact dB(A) levels vary by model, tooling and factory layout. If you need measured sound-pressure levels for compliance, request the manufacturer’s noise test report or arrange on-site measurement.

These cold-heading and thread-rolling machines are generally compatible with common fastener materials such as low-carbon steel, medium-carbon steel, stainless steels and some non-ferrous wires (brass, copper). Compatibility with specific alloys or pre-treated wire should be confirmed with the supplier and may require different tooling or process settings.

The machines are automatic and intended for high-speed production. An operator is typically required for feeding/setup, tooling changes, monitoring operations and quality checks. Additional automation (feeders, part conveyors, sorting/inspection) can often be integrated on request.

Tooling (headers, dies, rollers) is specific to part size and geometry. Tool changes are required for size changeovers; changeover time depends on the model and the operator’s experience. Spare tooling and complete die sets are normally available—discuss lead times and pricing with the supplier and consider keeping essential spares on hand.

Prepare a level, vibration-resistant concrete floor and sufficient clear space for the machine footprint plus operator access. Ensure stable electrical supply sized for the motor rating (confirm voltage/phase with supplier). Some installations may require foundations or anchoring; the supplier can provide installation instructions and recommend site preparation details.

Routine maintenance typically includes daily cleaning of chips and lubricant residues, inspection and lubrication of moving parts, checking and replacing worn dies/rollers, verifying alignment, and periodic inspection of electrical and pneumatic components. Follow the supplier’s maintenance schedule and keep a log of service actions.

Most suppliers provide spare parts, technical support and optional on-site or remote training for operators and maintenance personnel. Confirm the scope, costs and response times with your chosen supplier prior to purchase.

Yes—manufacturers commonly offer customization for part geometry, special tooling, additional automation (feeders, conveyors, inspection), and control integration to match existing production lines. Provide part drawings and production requirements so the supplier can propose a tailored solution.

Warranty, delivery lead-time and packaging/crating vary by supplier and order. Typical factory machines come with a limited warranty period and are shipped crated for export. Ask the supplier for a written quotation that includes warranty terms, lead times, shipping method and packaging details.
