• Deep Industry Heritage with 35 Years of Experience:

With nearly three decades of cumulative experience rooted in the Yuejin Holding Group, Zhejiang Yuejin Nonferrous Metal Manufacture Co., Ltd. has evolved into a trusted name in precision forging solutions. Since its formal establishment in 2006, the company has consistently delivered high-performance components for global automotive, mining, and industrial machinery markets. A standout example is our collaboration with a Tier-1 European automotive supplier based in Germany, which required over 150,000 high-pressure common rail components annually. These parts, made from 42CrMo steel alloy with a tensile strength exceeding 900 MPa, were designed to withstand extreme thermal and mechanical stress in modern diesel engines. Thanks to our CNC milling and EDM wire-cutting capabilities, we achieved a dimensional tolerance of ±0.02mm, ensuring perfect fitment and long-term reliability. The client reported a 30% reduction in engine failure rates after switching to our forged components, directly attributed to our strict material sourcing and precision manufacturing. This case exemplifies how our deep industry heritage enables us to anticipate engineering challenges and deliver robust, future-proof solutions. Our R&D team continuously invests in simulation tools and process optimization, allowing us to reduce defect rates by over 40% compared to industry averages. With over 80% of our workforce holding technical certifications and an annual R&D budget exceeding $1.2 million, we remain at the forefront of non-ferrous metal forging innovation.

--- Comprehensive Product Range ---

• Auto Engine and Chassis Parts:

Our product portfolio spans critical auto engine and chassis components, engineered to meet the exacting standards of global OEMs. One notable success story involves a major North American SUV manufacturer seeking lightweight yet durable steering knuckles for their new electric vehicle platform. Traditional cast iron components were too heavy, compromising energy efficiency and handling. We proposed a custom solution using 7075-T6 aluminum alloy, reducing component weight by 14% while maintaining a tensile strength of 500 MPa—exceeding OEM requirements. Using Haas VF-2 CNC machining centers with 5-axis capability, we achieved complex geometries with surface finish Ra < 1.6 μm. The final part passed rigorous fatigue testing (1 million cycles at 200 MPa) and was integrated into over 200,000 vehicles without field failures. Additionally, our high-pressure common rails (working pressure up to 2500 bar, burst pressure > 4000 bar) have been adopted by multiple German engine manufacturers, including those supplying BMW and Mercedes-Benz. These components feature a multi-port injection design (2–8 ports) and are manufactured using precision EDM wire-cutting to ensure leak-free sealing surfaces. The combination of superior material selection—such as 316L stainless steel for corrosion resistance—and advanced finishing techniques has enabled us to secure long-term contracts with several Tier-1 suppliers, reinforcing our reputation for reliability and performance in demanding automotive environments.

--- Custom Solutions Tailored to Your Needs ---

• Flexible Customization Services for Diverse Applications:

At Zhejiang Yuejin, we pride ourselves on delivering flexible customization services that adapt to the unique demands of each client. A prime example is our partnership with a South Korean ATV manufacturer looking to upgrade their suspension system for off-road durability. The original steel control arms were prone to fatigue cracking after 500 hours of operation. We developed a custom forging using 40Cr alloy steel, heat-treated to HRC 45–50, and machined using DMG Mori CMX 500 5-axis centers to achieve precise curvature and load distribution. The redesigned part passed 1,200 hours of accelerated fatigue testing under simulated mountain terrain conditions, outperforming the previous design by 80%. Moreover, we offer full-service customization—from concept to delivery—supporting PDF, DWG, STEP, and IGES formats, as well as physical sample replication. Another case involved a U.S.-based mining equipment firm requiring conveyor rollers for harsh desert environments. We customized rollers using Q235 steel with a hardened surface (HRC 42–45) and epoxy-coated shafts for enhanced corrosion resistance. The rollers operated continuously in temperatures above 60°C with zero maintenance for over two years. Our ability to tailor dimensions (diameter: 50–200mm, length: 300–2000mm), material grades (aluminum, steel, copper, stainless), and performance parameters makes us a preferred partner for companies seeking scalable, reliable, and innovative forging solutions across industries.

• Personalized Solutions Based on Customer Specifications:

We go beyond standard production by building true partnerships through personalized engineering support. A recent project with a Japanese robotics company illustrates this approach. They needed ultra-precise camshafts for a high-speed industrial robot arm, requiring a positioning accuracy of ±0.01mm and a surface hardness of HRC 58–62. Our team worked closely with their R&D department, using spectral analysis and microstructure inspection to validate raw material purity from Baowu Steel. We then employed CNC milling with real-time feedback systems to machine the cam profile with sub-micron precision. After successful prototype testing, we delivered 12,000 units over six months with zero rejection rate. Post-delivery, we provided lifetime technical support, including remote diagnostics via video conferencing and on-site calibration services. Similarly, a Brazilian agricultural machinery manufacturer required custom half shafts for their new line of tractors. We analyzed their operating torque and vibration profiles, then optimized the forging design to improve torsional strength by 25%. The final product reduced drivetrain noise by 15 dB and extended service life by over 40%. These cases highlight our commitment to understanding customer applications deeply and delivering not just parts—but performance-driven solutions that enhance operational efficiency and reduce lifecycle costs.

--- Efficient Logistics and Delivery Services ---

• Global Shipping Options for Timely Deliveries:

Our logistics network ensures fast, reliable delivery worldwide. In one instance, a German automotive supplier urgently needed 5,000 crankshafts for a production ramp-up. We leveraged air freight via DHL, delivering the entire order within 5 days—well ahead of schedule. For larger volume shipments, such as a 20-foot FCL container of 30,000 steering knuckles destined for Singapore, we coordinated sea freight via Maersk, achieving transit time of just 12 days. Our strategic location in Wenzhou, China, allows seamless access to Shanghai and Ningbo ports, enabling efficient consolidation and customs clearance. We also provide LCL services for smaller orders, reducing shipping costs by up to 30% for clients with fluctuating demand. Our real-time tracking system provides weekly production updates and shipment visibility, ensuring transparency throughout the supply chain. For clients in Europe and North America, we maintain pre-arranged customs documentation packages—including IATF 16949 certification reports, material certificates (EN 10204 3.1), and non-wood packing declarations—ensuring smooth clearance at destination ports like Hamburg, Rotterdam, and Los Angeles. This level of logistical sophistication has helped us maintain a 99.2% on-time delivery rate over the past three years, even during peak seasons and global disruptions.

• Door-to-Door Service for Hassle-Free Experience:

We offer end-to-end door-to-door logistics, eliminating the complexity traditionally associated with international procurement. A key example is our work with a U.S.-based construction equipment manufacturer who previously struggled with delayed deliveries due to customs bottlenecks. We took full responsibility for export documentation, inland transportation, and final delivery to their Ohio facility. Our dedicated account manager coordinated with local customs brokers, ensured compliance with U.S. import regulations, and managed all paperwork, including commercial invoices and certificates of origin. The entire shipment arrived within 18 days, including customs clearance and final delivery. Furthermore, we maintain a global spare parts warehouse in Shanghai, enabling rapid response to urgent repair needs. When a client in Australia experienced a sudden failure in their hydraulic pump body, we shipped a replacement part via FedEx within 48 hours, complete with installation guidance. Our 24/7 technical support team also provided live video assistance for on-site commissioning. This comprehensive service model has earned us repeat business from over 60% of our international clients, proving that reliability extends beyond the factory floor—it’s embedded in every stage of the supply chain.

--- Commitment to Quality and Customer Support ---

• Strict Quality Control and Material Inspection:

Quality is ingrained in every step of our process. At Zhejiang Yuejin, we source raw materials exclusively from certified suppliers such as Aluminum Corporation of China (CHALCO), Baowu Steel, and Jiangsu Shagang Group. Every batch undergoes rigorous incoming inspection using spectral analyzers for chemical composition, tensile testing machines for mechanical properties, and laser scanners for dimensional accuracy. For example, in a recent audit by a German automotive client, our material certificates (EN 10204 3.1) and test reports were found fully compliant with DIN and ISO standards. We also conduct wear testing on critical components like gears and bearings, simulating real-world conditions with 24/7 dynamic loading. One case involved a mining equipment client whose conveyor rollers were failing prematurely due to abrasive wear. We re-engineered the roller surface using a hard chrome plating process and conducted accelerated wear tests showing a 50% increase in lifespan. Our quality systems are certified under IATF 16949 and ISO 14001, and we maintain a digital traceability system that tracks every part from raw material to final shipment. This commitment to excellence has resulted in a defect rate below 0.15%, significantly lower than the industry average. Coupled with a 12-month warranty and lifetime technical support, our customers gain confidence that they’re not just buying parts—they’re investing in long-term performance and peace of mind.
