Explore our core manufacturing product series, engineering capabilities, and high-performance forged & cast components
In modern high-precision mechanical engineering, sourcing components fabricated by low-tonnage, highly controlled small forging machines is key to structural optimization. Unlike large structural forging units designed for heavy ship components or massive infrastructure, small and medium-capacity closed-die forging setups (typically operating within press forces of 100 to 1,000 tons) specialize in components requiring exceptional grain flow alignment, dimensional stability, and zero internal porosity. Global procurement directors in the automotive, aerospace, industrial safety, and medical device sectors prioritize small-scale forging machines to achieve complex geometries without sacrificing mechanical integrity.
The transition toward electrification, light-weighting, and clean energy storage places new demands on metallurgy. OEM suppliers must not only possess raw pressing machinery but also maintain deep technical portfolios in CAD/CAM die engineering, custom alloy thermal cycling, and secondary processes like multi-axis CNC machining, anodizing, and electropolishing. Ningbo Jiangbei XinYe Metal Works Co., Ltd. serves as an expert partner here, leveraging vertical manufacturing capabilities to supply high-stress structural parts directly to global industrial networks.
While casting operates by melting metal and pouring it into mold structures—which often leads to micro-porosity and structural weak points—the closed-die forging process compresses metal billets within their recrystallization range. Under controlled force, the metal flow is directed to realign its crystalline structure, matching the component's geometry. This results in superior tensile strength, ductility, and resistance to fatigue, allowing designers to reduce material thickness and weight while keeping security limits high.
Founded in 1996 as an owner-managed family enterprise, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has evolved into a leading, technology-driven SME specializing in custom precision metal manufacturing. Headquartered within the highly developed Jiangbei Industrial Zone in Ningbo, Zhejiang Province, our facility offers convenient logistical connectivity. We are located within a three-hour high-speed train transit circle from Shanghai International Airport, allowing for efficient direct client visits and technical alignment meetings.
Our operations occupy a total production floor space of 16,000 square meters, with an additional 11,000 square meters optimized for technical development, engineering offices, quality assurance spaces, and warehousing. Today, the XinYe team consists of 130 dedicated personnel, structured strategically to support complex engineering requirements: 80 skilled production specialists and 50 dedicated engineers in product development, quality control, process engineering, and management.
This layout ensures that our technical teams can communicate directly with customers' product design teams. This enables direct engineering support from initial CAD concept creation to prototype verification, high-volume production planning, and international supply chain coordination.

Precision closed-die hot forging requires balancing temperature, material flow dynamics, and tool wear rates. As an OEM manufacturer, Ningbo Jiangbei XinYe Metal Works Co., Ltd. continuously refines our process parameters to match client specifications. Our technological roadmap includes several advanced steps:
Before forging starts, our engineering team uses thermodynamic modeling software to predict how aluminum and steel alloys will flow inside the die cavity. Controlling the heating profile prevents mechanical issues like grain growth or shear cracking. Using high-efficiency induction heating, our billet preparation systems reach correct thermal ranges quickly, reducing surface oxidation and saving energy.
By studying how materials deform, we design closed-die forgings that place the natural grain flow direction along the paths of highest mechanical stress. This design helps prevent failure in parts subject to high cyclic fatigue, such as aerospace engine components, E-bike connector brackets, and automotive drivetrain hubs. Forging grain alignment yields tensile properties up to 25% higher compared to bar-stock machining alone.
For high-precision industrial output, we integrate state-of-the-art turn-mill technology, including the TIPAS MACHINE h65TMY. This advanced CNC system performs multiple operations in a single setup, integrating turning, milling, and axis indexing to reduce handling times. For our global customers, this technology delivers precise structural parts with minimal dimensional deviation between batches.

How we manage custom metal projects from early design to global shipping
Our process begins with an intake of your engineering drawings, materials parameters, and required tolerances. We perform a manufacturing review, looking for opportunities to improve tool life, reduce raw material waste, and optimize unit costs.
We configure the internal tooling and run test production batches. Samples are inspected in our laboratory, and we provide you with a comprehensive dimensional testing report and raw material verification certificates for final review.
You test the prototype parts in real-world application conditions. If modifications are needed, our design and production teams adjust the tooling geometry or thermal profile to resolve performance issues before mass production.
Once approved, we schedule production on our friction or hydraulic presses. Our QA inspectors perform regular dimensional and surface checks throughout the run. After forging and machining, parts undergo final mechanical testing and surface treatment.
Parts can be assembled in our clean workshop area to deliver complete sub-assemblies. We package parts using custom export crates and corrosion-preventive wrapping, ensuring they arrive safely at your facility via sea or air transport.
