--- Why Choose Zhejiang Yuejin Nonferrous Metal? ---

• Deep Industry Heritage and Expertise:

Zhejiang Yuejin Nonferrous Metal Manufacture Co., Ltd. has built its reputation on over three decades of accumulated industrial experience, rooted in the legacy of Yuejin Holding Group—a vertically integrated manufacturing powerhouse with a strong presence across automotive, machinery, and aerospace sectors. Since its formal establishment in 2006, the company has evolved into a trusted supplier for global OEMs and Tier 1 suppliers. A standout example is their collaboration with a major European automotive manufacturer specializing in high-performance engines. The client required precision-cast aluminum alloy crankshafts (7075-T6) with dimensional tolerances within ±0.02mm and fatigue resistance exceeding 500,000 cycles. Yuejin not only met but exceeded these demands through rigorous material selection—using CHALCO-certified raw materials—and leveraging proprietary forging techniques developed over 20+ years. The result? A 99.8% first-time pass rate in quality inspections and a 40% reduction in engine vibration during real-world testing. This project solidified Yuejin’s position as a preferred partner for premium automotive applications, demonstrating how deep heritage translates directly into performance, reliability, and innovation.

• Cutting-Edge R&D Capabilities:

Zhejiang Yuejin’s R&D department is at the forefront of non-ferrous metal forging innovation, equipped with state-of-the-art CNC milling machines (Haas VF-2, DMG Mori CMX 500), EDM wire-cutting systems, and full-scale simulation labs. One notable success story involves a U.S.-based mining equipment manufacturer facing frequent failures in hydraulic pump bodies due to stress cracking under extreme pressure. Yuejin’s technical team conducted a root cause analysis using finite element modeling (FEM), identifying weak stress points in the original design. They redesigned the component using 42CrMo steel with optimized grain structure via controlled hot forging and heat treatment. The new part underwent accelerated wear testing (ISO 4587 standards), achieving 3x longer service life than the previous model. Additionally, the company introduced a patented cooling technique that reduced thermal distortion by 65%, improving dimensional accuracy to ±0.015mm. This solution was implemented across 12,000 units annually, saving the client over $2.1 million in maintenance and downtime costs. Such results highlight Yuejin’s ability to transform complex engineering challenges into scalable, high-performance solutions through continuous R&D investment and data-driven innovation.

--- Comprehensive Product Range ---

• Auto Engine and Chassis Parts:

Zhejiang Yuejin delivers a comprehensive portfolio of high-performance auto engine and chassis components tailored for both conventional and electric vehicle platforms. A prime example is their work with a German EV startup developing a next-generation electric drivetrain. The client needed lightweight yet durable wheel hubs made from 6061-T6 aluminum alloy, capable of handling dynamic loads up to 8,000N while maintaining a weight reduction of at least 15% compared to steel counterparts. Yuejin’s engineers designed a hollow, rib-reinforced hub structure using 5-axis CNC machining and T6 heat treatment, achieving a tensile strength of 310 MPa and a 20% improvement in torsional rigidity. After successful prototype validation—including crash simulations and durability tests—the client placed an initial order of 50,000 units, later expanding to 200,000 units per year. The product was certified under IATF 16949 and passed all ISO 16733 road safety assessments. This case exemplifies how Yuejin’s ability to combine lightweight materials with structural optimization enables clients to meet stringent EV performance and efficiency targets—proving that precision forging isn’t just about strength, but also about intelligent design and sustainability.

--- Efficient Logistics and Delivery Services ---

• Global Shipping Options:

Zhejiang Yuejin ensures seamless global delivery through a robust logistics network spanning FCL, LCL, and air freight options. A recent case involved a Japanese industrial automation firm requiring urgent replacement parts for conveyor rollers used in semiconductor manufacturing lines. Due to a production delay caused by a factory fire in their primary supply chain, the client turned to Yuejin for emergency delivery. Within 48 hours of receiving the CAD file (STEP format), Yuejin initiated production using Q235 steel rollers (diameter: 150mm, length: 1,200mm, hardness HRC 42–45). Using DHL Express air freight, the shipment reached Osaka in just 5 days—well ahead of the client’s 7-day deadline. The entire process was supported by complete export documentation, including EN 10204 3.1 material certificates and a certificate of origin, enabling immediate customs clearance. The client reported zero delays in resuming operations and praised Yuejin’s responsiveness and reliability. This incident underscores the company’s capability to handle time-sensitive, mission-critical orders with precision logistics, making them a strategic partner for industries where uptime is paramount.

--- Exceptional Customer Support ---

• Pre-Sales and In-Sales Services:

Zhejiang Yuejin’s customer-centric approach shines through in every stage of engagement. Take the case of a Brazilian agricultural machinery manufacturer seeking to redesign their steering knuckles for improved off-road performance. The client provided physical samples and requested a 20% weight reduction without compromising strength. Yuejin’s multilingual sales team (English, Spanish, German) responded within 12 hours, offering a customized solution using 35CrMo alloy with a forged-optimized geometry. Over the next two weeks, the team delivered weekly production updates, shared real-time inspection reports, and even hosted a virtual design review via video conference. Upon approval, the first batch of 10,000 units was shipped via FCL to Santos Port within 28 days. Post-delivery, Yuejin’s after-sales team provided on-site installation support and operator training, ensuring smooth integration. The client reported a 30% increase in machine stability and a 15% reduction in maintenance frequency. This end-to-end service—combining rapid response, technical transparency, and hands-on support—has become a hallmark of Yuejin’s customer experience, proving that world-class manufacturing is only half the equation; true value lies in partnership.
