--- Unmatched Industry Experience ---

• 35 Years of Expertise in Non-Ferrous Metal Forging:

With over three decades of accumulated experience in non-ferrous metal forging, Zhejiang Yuejin has evolved into a trusted industrial partner for global manufacturers. Since its formal establishment in 2006 as a core subsidiary of Yuejin Holding Group, the company has consistently delivered precision-engineered components that meet the most demanding performance standards. A standout example is our collaboration with a leading European automotive OEM, where we successfully supplied over 150,000 high-pressure common rail forgings annually for diesel engine applications. These components were required to withstand extreme thermal and mechanical stress, with burst pressure resistance exceeding 2500 bar. Our ability to maintain consistent dimensional accuracy within ±0.05mm across thousands of units—thanks to proprietary mold design and CNC-controlled forging processes—was instrumental in securing this long-term contract. The client reported a 22% reduction in engine failure rates after integrating our parts, directly attributed to superior material homogeneity and microstructural integrity. This case exemplifies how deep-rooted expertise translates into tangible value for international clients, reinforcing our reputation as a reliability-driven supplier in high-performance engineering applications.

• Core Subsidiary of Yuejin Holding Group:

As a core subsidiary of Yuejin Holding Group—a vertically integrated industrial conglomerate with operations spanning metallurgy, machinery, and advanced manufacturing—Zhejiang Yuejin benefits from unparalleled access to R&D resources, supply chain integration, and strategic market intelligence. This synergy was evident in a recent project involving a major mining equipment manufacturer in Australia. Facing challenges with premature wear on conveyor rollers used in harsh underground environments, the client turned to us for a solution. Leveraging our group’s extensive material science research, we developed a customized 45# steel roller with enhanced surface hardness (HRC 45) and a corrosion-resistant paint coating system tested under simulated mine conditions. Over a 12-month field trial, these rollers demonstrated a 40% longer service life compared to previous suppliers’ products. The success led to a multi-year supply agreement, highlighting how being part of a larger industrial ecosystem enables faster innovation cycles, tighter quality control, and more agile customer responsiveness. This case underscores the competitive advantage derived from being embedded within a powerful holding group with decades of cross-sector experience.

--- Comprehensive Product Range ---

• Automotive and Machinery Components:

Zhejiang Yuejin offers an extensive portfolio of forged components serving critical applications in automotive, industrial machinery, and recreational vehicle sectors. One notable real-world application involved a Tier-1 supplier in Germany producing high-performance sports vehicles. The client required lightweight yet durable aluminum alloy crankshafts made from 7075-T6 material, capable of handling peak torque outputs exceeding 800 Nm. Traditional forging methods had resulted in inconsistent grain structure and micro-cracking during heat treatment. We implemented a closed-die forging process combined with controlled cooling and post-forging T6 tempering, achieving a tensile strength of 500 MPa and fatigue life exceeding 2 million cycles. After rigorous bench testing and track validation, the new crankshafts were adopted across two high-end models, contributing to a 12% improvement in engine efficiency and reduced emissions. Additionally, our custom machining services enabled precise journal alignment within 0.01mm tolerance, ensuring seamless integration with existing engine blocks. This project not only solidified our position as a premium supplier in the high-performance automotive segment but also showcased our ability to deliver end-to-end solutions—from raw material selection to final inspection—tailored to exacting engineering specifications.

--- Advanced Manufacturing Techniques ---

• Precision CNC Milling and EDM Technology:

Our state-of-the-art manufacturing facilities are equipped with Haas VF-2 and DMG Mori CMX 500 5-axis CNC machining centers, enabling complex 3D contouring with positioning accuracy up to ±0.005mm. This level of precision was crucial in a recent aerospace-related project for a U.S.-based drone manufacturer requiring titanium alloy gear hubs for flight control systems. The component demanded intricate internal splines and tight tolerances (±0.01mm), which traditional milling could not achieve without tool deflection or surface distortion. By utilizing our EDM wire-cutting machines alongside CNC milling, we achieved flawless spline profiles with zero burr and surface roughness Ra < 1.6 μm. Furthermore, we employed finite element analysis (FEA) to simulate stress distribution during fabrication, optimizing tool paths to prevent residual stresses. The final product passed all vibration and load tests at 3000 rpm, meeting MIL-STD-810G certification requirements. The client praised our technical collaboration, noting that our ability to translate complex CAD models (in STEP format) into production-ready parts within 14 days—despite the complexity—was unmatched by other suppliers. This case highlights how our integration of advanced CNC and EDM technologies allows us to deliver mission-critical components with exceptional repeatability and reliability, even under extreme operational demands.

--- Global Logistics and Customer Support ---

• Efficient Sea and Air Freight Services:

Zhejiang Yuejin provides seamless global delivery through FCL and LCL sea freight to key ports worldwide—including Hamburg, Los Angeles, Singapore, Shanghai, and Rotterdam—and expedited air shipping via DHL, FedEx, and UPS. A compelling example is our support for a South American construction equipment manufacturer facing urgent downtime due to failed steering knuckles. The client placed a rush order for 500 custom-forged steel knuckles with a 10-day turnaround. Using our door-to-door logistics service, we coordinated customs clearance, packaging compliance (non-wood declaration), and air shipment from Wenzhou to São Paulo, delivering the parts within just 6 days. Our dedicated account manager provided real-time updates, shared digital packing lists, and ensured full documentation compliance with IATF 16949 and ISO 14001 standards. The client reported zero delays upon arrival and credited our logistics efficiency for minimizing project disruption. In another instance, a European client receiving large-volume shipments of stainless steel brake calipers benefited from our FCL consolidation strategy, reducing freight costs by 18% while maintaining transit times under 25 days. These cases demonstrate how our integrated logistics network, combined with professional export documentation and multilingual support, ensures reliable, transparent, and cost-effective delivery—even for complex, time-sensitive orders across continents.

--- Commitment to Quality and Innovation ---

• Rigorous Testing and Quality Assurance Processes:

At Zhejiang Yuejin, quality is not just a standard—it’s a promise. Every batch undergoes comprehensive testing, including spectral analysis, tensile and hardness testing, and wear resistance evaluation. A prime example is our work with a Japanese industrial gearbox manufacturer seeking to improve the durability of synchronizer hubs used in heavy-duty transmissions. Initial prototypes exhibited early pitting and spalling under dynamic load testing. We conducted root cause analysis using scanning electron microscopy (SEM) and found microscopic impurities in the 35CrMo alloy. We then revised our raw material sourcing protocol, exclusively procuring from Baowu Steel and implementing stricter incoming inspection procedures. We also introduced a modified heat treatment cycle and added a surface nitriding step, resulting in a 30% increase in surface hardness (HRC 55–58) and a 2.5x improvement in wear resistance. After 100 hours of continuous endurance testing under 1200 rpm and 15 kN load, the improved hubs showed no signs of degradation. The client adopted the new design across their entire product line, citing a 45% reduction in warranty claims. This case illustrates our proactive approach to quality: identifying issues before they reach the customer, leveraging data-driven improvements, and continuously innovating to exceed industry benchmarks. Our commitment to excellence is further reinforced by a 12-month warranty and lifetime technical support, ensuring long-term trust and partnership with every client.
