About the Manufacturer
Xingtai Qiangqi Machinery Manufacturing Co., Ltd. is a machinery producer based in Hubei, China. Its product portfolio encompasses electric and self-propelled forklifts, stair climbers, thread rolling machines, and punching and shearing equipment. The company provides machinery test reports and video outgoing-inspection for its thread rolling unit, supporting buyer qualification processes. Direct engagement with the supplier is advised to verify the latest production capabilities and factory certifications.
Industry Applications
Thread rolling is a cold-forming process widely employed to manufacture external threads on bolts, studs, and certain nut blanks. Unlike thread cutting, rolling displaces material rather than removing it, resulting in work-hardened, continuous grain flow threads with superior fatigue resistance and surface finish. This method is standard in automotive, construction, and general engineering fasteners where consistent mechanical properties are critical.
The machine under review accommodates roller diameters from 5 mm to 36 mm, enabling the production of threads across a broad range of metric and imperial sizes. With an unlimited thread length capability, it is suited for long threaded rods and studs. The steel construction of the machine’s main components ensures durability even in high-volume, multi-shift environments. Power input is rated at 4 kW (other voltage options available on request), making the machine compatible with typical industrial power supplies.
Technical Specifications and Performance
The following table summarizes the key engineering parameters reported by the supplier. All values should be confirmed directly with Xingtai Qiangqi prior to procurement.
| Parameter | Value |
|---|---|
| Main Drive Power | 4 kW |
| Voltage (Standard) | 380 V (customizable) |
| Core Control Components | PLC (Programmable Logic Controller) |
| Operation Mode | Automatic |
| Spindle Speed | 39, 49, 66, 82 r/min |
| Production Capacity (Linear) | 3–6 meters/min |
| Maximum Rolling Pressure | 140 kN |
| Roller Diameter Range | 5–36 mm |
| Shaft Diameter | 54 mm |
| Thread Length Capability | Unlimited |
| Dynamic Feed Speed | 5 mm/s |
| Machine Weight | 3000 kg |
| Machine Dimensions (L×W×H) | 1350 × 1210 × 1050 mm |
| Warranty | 1 year |
Note: An additional production capacity figure of 1/10 s per piece appears in supplier data; this likely refers to cycle time for small fasteners. Clarify intended workpiece size during inquiry.
- High throughput potential: With linear output up to 6 m/min and four selectable spindle speeds, the machine can be tuned to balance speed and surface finish for different thread pitches and materials.
- Precision automation: The PLC-driven control system supports consistent feed rates and pressure application, reducing operator dependency and scrap rates.
- Wide workpiece range: Roller diameters as small as 5 mm allow fine threads, while the 36 mm upper limit covers medium-sized bolts. The unlimited thread length removes restrictions on stud production.
- Robust build: Steel construction and a 3000 kg mass contribute to vibration dampening and dimensional stability under 140 kN rolling forces.
Packaging and logistics: Each unit is shipped as a single item with approximate package dimensions of 1500 × 1410 × 1250 cm and a gross weight of 1200 kg. These figures should be validated for container loading and freight costing.
Customization and Quality Assurance
The standard machine operates at 380 V, but the supplier indicates that voltage can be customized to meet regional power requirements. Additional parameter adjustments—such as spindle speed presets or roller configurations—may be available upon request. Formal OEM arrangements are not detailed in the provided data; therefore, buyers should discuss branding, manual languages, and any specific conformity requirements directly with Xingtai Qiangqi.
Pre-shipment verification is supported by the supplier’s provision of machinery test reports and outgoing inspection videos. These documents can serve as initial qualification evidence before third-party inspection or factory acceptance testing.
Procurement Next Steps
Import managers and distributors evaluating this thread rolling machine should prepare a detailed technical questionnaire: confirm motor rating, supply voltage tolerance, exact cycle time for the target thread specification, roller material and hardness, and available spare parts kits. Request a sample test report for a thread profile similar to your production needs. Engagement through direct factory communication allows verification of the 1-year warranty terms, lead times, and packaging suitability for ocean freight.
To initiate the procurement process, contact Xingtai Qiangqi Machinery Manufacturing Co., Ltd. with your throughput targets and thread specifications. Reputable B2B platforms may facilitate initial contact, but direct technical discussions with the manufacturer’s engineering team are recommended to align on acceptance criteria and after-sales support.
Engineering Disclaimer
All specifications and capabilities mentioned in this brief are based on supplier-provided data and are presented for reference only. Final engineering approval must rely on a documented technical confirmation from the manufacturer, including detailed installation, operation, and safety requirements. Performance figures may vary depending on tooling, material grade, and operating conditions. Buyers are advised to conduct their own due diligence, including factory audits and equipment trials, before finalizing any purchase agreement.
