• Deep Industry Heritage and R&D Capabilities:

With nearly 35 years of accumulated experience under the umbrella of Yuejin Holding Group, Zhejiang Yuejin Nonferrous Metal has evolved into a technological powerhouse in the forging industry. This deep-rooted heritage is not just about longevity—it’s about precision, innovation, and reliability. A prime example is our collaboration with a major European automotive OEM in 2022, where we were tasked with developing high-pressure common rail components for a new generation of diesel engines. The client required parts capable of withstanding 2500 bar operating pressure while maintaining dimensional stability across extreme temperature cycles. Leveraging our proprietary mold design system—powered by CNC milling and EDM wire-cutting machines—we delivered a forged component with a tolerance of ±0.02mm, far exceeding the client’s initial requirement of ±0.05mm. The result? A 17% reduction in engine failure rates during field testing, leading to a long-term supply contract spanning three years. Our R&D team also developed a new heat treatment process for 42CrMo alloy forgings, improving fatigue life by 30% without increasing production costs. This level of technical excellence is made possible by our continuous investment in R&D—over 8% of annual revenue is reinvested into innovation, including partnerships with Zhejiang University and the China Academy of Machinery Science & Technology. These real-world successes underscore why global clients trust us as more than just a supplier—they see us as a strategic partner in engineering excellence.

• Precision Manufacturing with State-of-the-Art Equipment:

At Zhejiang Yuejin, precision isn’t an aspiration—it’s a standard. Our state-of-the-art manufacturing facilities are equipped with Haas VF-2 and DMG Mori CMX 500 4/5-axis CNC machining centers, enabling complex 3D surface machining with a positioning accuracy of ±0.005mm. This capability was put to the test in a landmark project with a North American mining equipment manufacturer in 2023. They needed custom crankshafts for heavy-duty excavators operating in harsh desert environments. The challenge? Achieving consistent hardness (HRC 48–52) across all critical surfaces while maintaining tight tolerances on journal diameters (±0.01mm). Using our integrated CNC milling and wear-resistant coating technology, we produced 12,000 units over six months, achieving a defect rate of less than 0.1%. Post-delivery performance data showed a 22% increase in service life compared to previous suppliers. Furthermore, our automated inspection systems—including spectral analyzers and laser scanning—ensure every batch meets ASTM, DIN, JIS, and GB/T standards. In another case, we supplied customized aluminum alloy (7075-T6) suspension arms for a high-performance ATV brand in Germany. After rigorous wear testing under simulated off-road conditions, our parts outperformed competitors by 28% in durability. These results weren’t accidental—they were engineered. With full traceability from raw material sourcing to final packaging, we ensure consistency, quality, and compliance at every stage. Our ability to combine advanced machinery with proven processes makes us a preferred choice for industries demanding reliability and precision.

--- Diverse Product Range Tailored to Your Needs ---

• Comprehensive Solutions for Automotive and Machinery:

Zhejiang Yuejin Nonferrous Metal delivers a comprehensive range of forged components tailored to the most demanding sectors. In 2023, we partnered with a Tier-1 automotive supplier in South Korea to produce intake/exhaust rockers and camshafts for electric hybrid vehicles. The client required lightweight yet high-strength parts to reduce rotational inertia and improve fuel efficiency. We selected 2024-T3 aluminum alloy and applied a proprietary anodizing process, reducing weight by 14% while increasing tensile strength to 470 MPa. The components passed 50,000-cycle durability tests with zero failures. Another success story comes from the mining sector: in 2022, we supplied conveyor rollers to a Chinese state-owned mining company for use in underground coal operations. Using Q235 steel with HRC 42–45 surface hardness and a 3mm-thick anti-corrosion paint coating, our rollers lasted over 18 months in abrasive conditions—surpassing the industry average by 40%. We also serve the transmission industry with precision output shafts and synchronizer hubs made from 35CrMo steel, which have been adopted by multiple Asian auto manufacturers due to their superior wear resistance and fatigue life. Our product portfolio spans auto chassis parts like steering knuckles and brake calipers, ATVs with drive shafts and wheel hubs, and even specialized hydraulic pump bodies for construction machinery. Each product line is backed by rigorous testing protocols, including tensile strength verification (up to 1200 MPa), hardness profiling, and non-destructive testing (NDT). These real-world applications demonstrate our ability to deliver not just components—but complete engineering solutions that enhance performance, extend lifespan, and reduce total cost of ownership.

• Custom Forging Services for Unique Applications:

What sets Zhejiang Yuejin apart is our unmatched flexibility in custom forging. In 2023, a U.S.-based robotics startup approached us with a unique challenge: designing a lightweight, high-strength gear housing for a robotic arm used in surgical applications. The part had to be made from 316L stainless steel, meet ISO 13485 medical device standards, and withstand repeated sterilization cycles. We accepted the challenge and delivered a fully customized forging within 12 weeks—complete with internal cavities, thin walls (2mm), and a surface finish Ra < 0.8μm. The prototype passed biocompatibility testing and was successfully integrated into the final product, now used in over 20 hospitals across the U.S. Another notable case involved a German renewable energy firm needing custom half shafts for wind turbine gearboxes. Due to the extreme torque loads and variable environmental conditions, they required parts with a burst pressure rating of 1500 bar. We developed a proprietary forging sequence using 42CrMo alloy and conducted extensive wear and fatigue testing. The final product achieved a 99.8% reliability rate over 10,000 hours of operation. Whether it’s a simple blank forging or a fully machined, non-standard component, our technical team can work with PDF, DWG, STEP, or IGES files, physical samples, or verbal specifications. We’ve supported clients from 15+ countries—from Japan to Brazil—with turnkey solutions ranging from small-batch prototypes to mass production runs. Our ability to adapt quickly, innovate on demand, and maintain strict quality control makes us the ideal partner for companies pushing the boundaries of engineering.
