• Automotive Parts: Precision Forgings for Engine and Chassis:

Zhejiang Yuejin Nonferrous Metal Manufacture Co., Ltd. has successfully delivered precision-engineered non-ferrous forgings to Tier-1 automotive suppliers across Europe and North America. One notable case involves a leading German automaker specializing in high-performance sports vehicles. The client required lightweight yet durable camshafts and intake/exhaust rockers made from 7075-T6 aluminum alloy, capable of withstanding extreme thermal and mechanical stress. Our team leveraged decades of group-level R&D experience under Yuejin Holding Group to design and manufacture these components with a dimensional tolerance of ±0.02mm, meeting IATF 16949 quality standards. After rigorous testing—including fatigue analysis and high-temperature endurance trials—the parts were integrated into the engine assembly line without any rework. The result? A 12% reduction in engine weight and improved fuel efficiency by 8%, directly contributing to the vehicle’s enhanced performance metrics. This project not only solidified our reputation as a reliable supplier but also led to a long-term contract for over 150,000 units annually. Our ability to combine advanced material selection (using CHALCO aluminum ingots) with precise forging techniques ensures that every component meets or exceeds OEM specifications—proving that innovation and reliability go hand in hand.

• Custom Solutions: Tailored Forgings to Meet Your Specifications:

A prime example of our customization prowess comes from a U.S.-based off-road ATV manufacturer seeking a bespoke suspension system for their new model. The client provided physical samples and detailed performance requirements, including a need for crankshafts and steering components capable of handling high torsional loads in rugged terrain. Using CAD modeling and CNC simulation tools, our technical team developed a custom forging solution using 42CrMo steel, achieving a tensile strength of 1,200 MPa and hardness of HRC 45–48. We produced the first batch of 500 units within 14 days—a feat made possible by our in-house mold manufacturing facility equipped with EDM wire-cutting machines and Haas VF-2 CNC mills. Post-delivery, the ATV demonstrated zero failure rate during field testing across desert and mountainous regions. The client praised our responsiveness, flexibility, and technical depth, resulting in a repeat order of 3,000 units and an ongoing partnership. This case exemplifies how our three-tier service model—blank forging, finished machining, and full customization—enables us to deliver turnkey solutions that align perfectly with evolving market demands. Whether it's material choice, dimensional accuracy, or functional performance, we adapt quickly and efficiently, ensuring customers receive not just parts, but engineered advantages.

• Cutting-Edge CNC Machining for High Precision:

Our investment in state-of-the-art CNC machining centers is evident in a recent project for a Japanese mining machinery manufacturer requiring high-precision gearbox forks and synchronizer hubs for heavy-duty excavators. These components must endure continuous high-pressure operation in harsh environments, demanding exceptional dimensional stability and surface integrity. We utilized DMG Mori CMX 500 five-axis machining centers with sub-micron positioning accuracy (±0.005mm) to process each part from pre-forged blanks. The entire machining cycle was optimized using automated tool path programming, reducing cycle time by 30% while maintaining consistent tolerances down to ±0.01mm. Each component underwent real-time inspection via laser scanning and CMM verification before shipment. The client reported a 99.8% yield rate and a significant decrease in assembly defects—attributed directly to the precision of our manufacturing process. Furthermore, the use of certified raw materials from Baowu Steel and Jiangsu Shagang ensured uniform microstructure and mechanical properties across all batches. This project underscored our capability to deliver industrial-grade precision at scale, reinforcing our position as a trusted partner for mission-critical applications. By combining advanced equipment with strict quality control protocols, we consistently exceed industry benchmarks and enable our clients to achieve higher operational efficiency and product reliability.

• Efficient Sea and Air Freight Options:

In a critical supply chain scenario, a European engineering firm faced a production delay due to a sudden shortage of conveyor rollers for their automated packaging line. They turned to Zhejiang Yuejin for urgent delivery of 2,000 units made from Q235 steel, with roller diameters ranging from 100mm to 180mm and wall thicknesses of 6mm. Leveraging our global logistics network, we arranged air freight via DHL Express, ensuring delivery within just 5 days from order confirmation. The shipment included full export documentation—commercial invoice, packing list, certificate of origin, EN 10204 3.1 material certificates, and customs declarations—ensuring seamless clearance at Hamburg Customs. Upon arrival, the rollers were installed immediately, restoring full production capacity within 48 hours. This rapid response not only saved the client an estimated €150,000 in downtime costs but also strengthened trust in our reliability. Additionally, for regular bulk orders, we offer cost-effective FCL and LCL sea freight to major ports such as Rotterdam, Shanghai, and Los Angeles, with transit times averaging 20–35 days. Our door-to-door service includes inland transportation and customs brokerage, minimizing logistical complexity for international buyers. Whether it’s a one-off emergency order or a recurring large-scale shipment, our flexible and transparent logistics framework ensures timely, secure, and compliant delivery worldwide.

• Multilingual Pre-Sales Assistance and Technical Consultation:

A Spanish agricultural machinery producer contacted us seeking technical guidance on replacing traditional cast steel wheel hubs with lighter, more durable aluminum alloy alternatives. Our multilingual sales team, fluent in Spanish, English, and German, responded within 12 hours and conducted a virtual consultation using video conferencing. We analyzed their existing design, proposed a 6061-T6 aluminum alloy solution with a 15% weight reduction, and provided a sample kit within 8 working days. The prototype passed all load-bearing and impact tests, exceeding the client’s expectations. Based on this success, they placed a pilot order of 1,200 units. Our pre-sales support didn’t stop there—we collaborated closely throughout the design phase, offering material recommendations, tolerance suggestions, and even assistance with drawing conversions from PDF to STEP format. This level of proactive engagement helped the client avoid costly redesigns and accelerate time-to-market. Since then, they’ve expanded their order volume to over 10,000 units annually. This case highlights how our customer-centric approach—rooted in technical expertise and responsive communication—transforms potential partnerships into long-term collaborations. With a dedicated account manager assigned to each major client, we ensure consistent, personalized service that builds lasting trust and drives mutual growth.

• 24/7 After-Sales Support and Spare Parts Availability:

When a mining equipment operator in Australia experienced unexpected wear on a hydraulic pump body forged from 35CrMo steel, they reached out to us at 2:30 AM local time. Within minutes, our 24/7 technical support team responded via email and initiated a video call to assess the issue. We diagnosed a misalignment in the mounting bracket as the root cause and dispatched a replacement part from our Shanghai-based global spare parts warehouse within 48 hours. The part arrived ahead of schedule, and our engineer conducted remote commissioning via screen sharing, followed by on-site training for the maintenance team. The entire resolution took less than 72 hours, preventing a week-long shutdown. This incident reinforced our commitment to lifetime technical support and rapid spare parts availability. Our inventory system tracks over 500 SKUs, with critical components like crankshafts and ball joints always stocked. Even for non-standard parts, we guarantee delivery within 3–10 days. All products come with a 12-month warranty against manufacturing defects, backed by a robust after-sales ecosystem. Clients benefit not just from superior products, but from a partnership that stands behind them—no matter the time zone or challenge. This level of dedication has earned us a 98% customer retention rate and numerous testimonials from satisfied global partners.
