Wuyuan Jieyi Automotive Electrical Appliance Co., Ltd. was established in 2010. Originating within a fastener industry cluster, the company deeply cultivated the local market; through reliable delivery and a reputation for pragmatism, it achieved its initial capital accumulation and laid a solid foundation in professional cold-forging manufacturing. As the enterprise expanded in scale, it introduced multi-station cold-forging machines, thread-rolling machines, and automated production lines, thereby aligning its product offerings with the industry's trend toward high-end specialization. The company comprehensively advanced the development of its quality management system, successfully obtaining ISO quality management certification as well as IATF 16949 certification for the automotive industry, thereby officially integrating into the automotive supply chain. Furthermore, the company introduced precision inspection equipment and implemented management tools such as APQP, PPAP, and FMEA, focusing its product portfolio on critical components for automotive chassis, engines, and body systems. Over the years, guided by a philosophy of bold innovation, optimistic enterprise, and integrity-based operations, the company has remained dedicated to the cold-forging sector-continuously iterating its technology, upgrading its management practices, and expanding its market reach. Moving forward, the company will continue to deeply cultivate the fields of precision cold-forging and high-end fasteners, striving to provide customers with superior products and services while dedicating itself to becoming a trusted, professional manufacturer within the industry.
Our Factory
Our company specializes in the R&D, manufacturing, and sales of high-strength fasteners, custom cold-forged parts, automotive standard components, and non-standard fasteners. Our product portfolio encompasses a wide range of items-including bolts, screws, rivets, dowel pins, locating pins, shafts, stepped shafts, and custom cold-forged components-and finds extensive application across sectors such as automotive manufacturing, construction machinery, rail transit, new energy, general machinery, and power equipment. Our market strategy centers on serving domestic OEMs and Tier-1 suppliers, while simultaneously expanding into overseas markets; our sales network spans all major industrial cities across China, with products exported to countries and regions throughout Southeast Asia, the Middle East, and Europe. Adhering to a market strategy defined by high quality, rapid delivery, and customized solutions, we have long provided stable supply chain support to numerous renowned enterprises, thereby establishing a strong brand reputation and significant market competitiveness within the specialized fastener sector.
Our fasteners are backed by rigorous quality assurance; they exhibit high fatigue resistance, are resistant to bending, offer a long service life, and-having passed salt spray testing-demonstrate excellent corrosion and rust resistance. With a daily production capacity reaching 1.5 million units, our company has earned the trust of both domestic and international vehicle manufacturers and component suppliers through our robust manufacturing capabilities and extensive experience in providing integrated supply services, establishing ourselves as a leading and well-respected supplier of automotive components within the industry. Our products are positioned for the high-end market, and our key clients include major industry leaders such as SAIC Group, FAW Group, Dongfeng Group, GAC Group, Great Wall Motor, Geely Auto, and Chery Auto.
Our Quality
Our company has established a standardized laboratory equipped with a full set of precision testing equipment, enabling independent testing of all aspects of raw materials and finished products. We use data to control the quality of every process.
◆ Digital Rockwell Hardness Tester: Tests the surface hardness of fasteners, verifying the compliance of cold heading and heat treatment processes;
◆ Micro Vickers Hardness Tester: Accurately tests the hardness of coatings and thin-walled small parts, controlling surface metallographic properties and machinability;
◆ JVB250 2D Image Measuring Instrument: High-precision measurement of product contours, hole diameters, and dimensional tolerances, ensuring the machining accuracy of parts;
◆ Precision Salt Spray Tester: Conducts neutral salt spray corrosion tests, verifying the rust and corrosion resistance of product coatings.
From mechanical strength and precision dimensions to corrosion and weather resistance, we conduct comprehensive testing and verification. We insist on using standardized test data to ensure quality and strictly control the outflow of defective products, providing customers with stable and reliable non-standard fastener products.
Heat treatment determines the inherent mechanical properties of fasteners, while surface treatment provides long-term protection.
We rely on mature and stable heat treatment processes to precisely control quenching and tempering parameters, consistently maintaining the tensile strength, hardness, and toughness of our products. This avoids brittle fractures and deformation defects, ensuring the reliability of components under long-term stress conditions.
We offer a variety of surface treatment solutions, including galvanizing, Dacromet coating, black zinc plating, and blackening, tailored to customer needs. Our laboratory salt spray tests continuously verify the anti-corrosion effect, strictly controlling coating thickness and adhesion to effectively resist corrosion in humid and salt spray environments.
With internally strong material toughness and an external protective barrier, our dual internal and external process control meets the long-term stable use requirements of automotive motor components.
We primarily specialize in bolts, screws, pins, locating pins, cylindrical pins, shafts, stepped shafts, semi-tubular stainless iron rivets, iron limit rivets, slotted stainless steel rivets, solid rivets, support pins, brake pad rivets, iron tubular limit rivets, and various cold-forged specialty parts.
