As a professional domestic manufacturer of motorcycle sprockets and chains, Renqiu Shijia Motorcycle‑Parts Co., Ltd. keeps advancing the intelligent transformation and upgrading of its production lines. Leveraging the industrial cluster advantages of Shimenqiao Town, the company has completed the optimization and commissioning of multiple large‑tonnage fully‑automatic production lines. At present, its monthly comprehensive production capacity has steadily surpassed 650,000 sets, with synchronous improvements in product delivery efficiency, dimensional accuracy and finished‑product yield.
The production‑line upgrade covers the full‑process procedures including stamping, heat treatment, quenching, assembly and defect inspection. Newly‑added automated chain defect‑detection machines, static‑load pre‑stretching equipment and continuous oil‑coating & cooling assembly lines reduce dimensional deviations caused by manual operation. Therefore, the heat‑treatment uniformity and tensile strength of every batch of sprockets and chains stay more stable. To satisfy large‑volume orders from overseas markets, the optimized production lines further shorten the order‑delivery cycle, enabling the enterprise to better undertake large‑scale chain‑kit orders from clients across South America, the Middle East and Southeast Asia.
“Automation is not merely about adding equipment. The core lies in integrating our 20‑year‑long accumulated craftsmanship for sprocket and chain manufacturing into equipment‑based workflows,” stated the factory’s technical director. A closed‑loop management system runs through the whole workshop workflow, ranging from incoming steel raw‑material inspection, stamping‑forming, heat‑treatment strengthening and surface treatment to comprehensive finished‑product testing. All finished goods undergo hardness testing, tensile tests and salt‑spray anti‑corrosion inspections before shipment. In compliance with the ISO9001:2015 quality‑management system, inspection control points are implemented in every working procedure.
Moving forward, the enterprise will continuously strengthen its independent mould‑research‑and‑development capability. New‑model sprockets and chains will be rapidly developed for popular motorcycle models in markets such as Colombia, Indonesia and Brazil. The company will further enrich its product portfolio and supply global customers with stable, cost‑effective solutions for transmission accessories.
