Import Bolt Making Machine — Buy in wholesale FOB from Supplier in China

The bolt making machine from Zhejiang Shengtuo Machinery Co.,Ltd. is a multi-station cold forming unit designed to produce threaded fasteners from wire coil feedstock. The cast iron body provides vibration damping and structural rigidity for high-impact forging operations, while hardened steel tooling components handle the progressive forming, heading, and threading stages. The supplier describes CNC-controlled automation with automated feeding, forging, and threading operations, though specific spindle speed, forging force, or die station count are not quantified in the source material. This type of equipment typically processes carbon steel wire from 4mm to 24mm diameter, producing bolts to ISO 898-1 or ASTM A307/A449 mechanical property requirements.

Cold heading and thread rolling form the bolt without material removal, preserving grain flow and achieving tensile strengths that exceed machined equivalents. The machine likely incorporates a straightening and feeding mechanism, a cut-off station, one or more heading dies for upset forging of the bolt head, and thread rolling dies for profile generation. Hardened steel tooling is standard for this equipment class, with typical die life measured in millions of pieces before regrinding or replacement. The modular design mentioned by the supplier allows replacement of individual forming stations and adaptation to different bolt specifications through die changes, a critical factor for plant flexibility.

Primary buyers include construction fastener manufacturers, automotive tier suppliers, and general industrial hardware producers serving OEM and aftermarket channels. The machine suits operations producing hex head bolts, flange bolts, and specialty fasteners in batch or continuous production modes. Zhejiang Shengtuo Machinery Co.,Ltd. does not list specific output rates, power consumption, or footprint dimensions. Buyers should confirm directly with the supplier the maximum wire diameter, bolt length capacity, strokes per minute, motor power, and whether the control system uses a proprietary PLC or industry-standard architecture such as Siemens or Mitsubishi. The supplier mentions ISO and CE certifications in their marketing, but buyers must request current certificate scope and validity dates to confirm these apply to this specific machine model.

Zhejiang Shengtuo Machinery Co.,Ltd. is located in Xiawan Village, Ruian, Wenzhou, Zhejiang Province, China, postal code 325200. The Ruian region is a recognised cluster for fastener and automotive component manufacturing in China, with established supply chains for steel wire, heat treatment, and surface finishing services. The supplier holds a harbor trust tier and an imported supplier tier classification. No response rate or average response time data is available, indicating limited track record on the platform for buyer communication metrics.

The supplier profile does not disclose year of establishment, factory floor area, number of employees, annual revenue, or export markets served. No specific machine models beyond this bolt making machine are catalogued in the provided data. The source description contains platform marketing language that buyers should treat with caution, particularly claims about operational excellence and competitive rates. Direct verification with Zhejiang Shengtuo Machinery Co.,Ltd. is necessary to establish whether they manufacture this equipment in-house or source from an OEM, what after-sales support they provide, and whether they have reference installations in the buyer's target market.
