Explore our main capabilities in casting, forging, stamping, and high-precision CNC machining.
Founded in 1996 as an owner-managed SME corporation, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has spent over a quarter of a century evolving into a key manufacturing partner for global enterprise buyers. Positioned in the Ningbo Jiangbei Industrial Zone, our facility sits in the heart of East China’s technological and metallurgical ecosystem, accessible within 3 hours from Shanghai International Airport via high-speed rail.
Spanning 16,000 square meters of specialized production floor with another 11,000 square meters designated for continuous structural expansion, our facility is optimized for scalable manufacturing. Driven by a dedicated workforce of 130 professionals, our structural layout allocates 80 highly skilled production technicians and 50 specialists in product development, engineering design, quality control, and global supply logistics.
As a supplier to Europe, North America, and global industrial markets, we deliver custom manufacturing solutions covering CNC machining, aluminum hot forging, wax die stainless casting, metal stamping, and specialized electro-polish and anodizing surface treatments.
A comprehensive metallurgical capability portfolio designed to translate complex 3D CAD data into high-integrity components.
Utilizing high-capacity friction presses (300T to 1000T force) and column hydraulic systems, we forge raw billets under controlled temperatures. This process refines the grain flow structure of stainless steels and aluminum alloys, eliminating interior voids and maximizing tensile strength and fatigue resistance in high-stress applications.
Our lost wax casting process replicates complex geometries with thin walls, intricate internal channels, and high surface definition. By pouring liquid stainless steel into specialized ceramic molds, we produce net-shape components that minimize raw material waste and downstream machining overhead.
Equipped with 4-axis CNC machining centers, high-speed turning centers, and milling units, we execute precise subtraction operations. We maintain tolerances down to 0.001mm, ensuring alignment and dimension control for components integrating casting and forging pre-forms.
Operating a press lineup ranging from 5T to 250T force, we process structural metal plates, deep-drawn enclosures, and structural flanges. We handle copper, aluminum alloys, structural steels, and engineering plastics with high repeatability across production volumes.
We provide chemical anodizing for structural aluminum alloys and electrochemical polishing (E-polish) for stainless steels. These electrochemical processes remove surface impurities, smooth micro-irregularities, and form a passive chromium oxide layer to prevent corrosion in demanding environments.
We extend our services beyond fabrication. Operating a dedicated, clean assembly workshop, we combine forged, cast, stamped, and machined parts with external hardware and gaskets. This delivers complete mechanical sub-assemblies directly to our clients' production lines.
Procuring raw metals and forged components from Ningbo Jiangbei XinYe provides structural efficiency, logistics speed, and regional ecosystem advantages for global companies:
Located near one of the world's largest deep-water shipping terminals, we offer direct routes to major ports, minimizing land transport times and reducing export transit costs.
Our location in Zhejiang Province provides direct access to high-grade steel mills, heat treatment facilities, and tooling specialists. This reduces lead times for raw materials and custom tooling.
Operating a standard 16-hour, 6-day production schedule, our facility can transition to 24/7 continuous operations within 30 days. This allows us to scale production to meet sudden demand surges.
Aligning with international quality, safety, and social accountability standards to ensure seamless supply chain integration.
Our manufacturing and engineering processes are governed by an ISO 9001:2015 certified quality system. We maintain dimensional control, material verification, and full traceability throughout the production lifecycle.
We maintain an audited SA8000 certified social environment. This compliance supports the corporate governance and ESG supply chain requirements of our European and North American partners.
We provide full verification for chemical composition and physical properties, ensuring conformity to ASTM, DIN, EN, and JIS standards. We also support RoHS and REACH compliance for electrical and automotive applications.
How modern technological integration is shaping the future of industrial metal manufacturing.
Demanding industrial applications are driving a shift toward super-duplex stainless steels and specialized high-nickel alloys. We continuously optimize our heating profiles, mold designs, and tooling to process these materials. This ensures high structural stability and pitting corrosion resistance for harsh marine and chemical environments.
We utilize advanced solidification and thermal flow analysis software to simulate forging and casting cycles before cutting steel tooling. This digital prototyping identifies potential flow lines, air entrapment, and shrinkage defects. By resolving issues during the design phase, we reduce development times and tooling costs.
By pairing near-net-shape investment casting with precision multi-axis CNC finishing, we minimize material scrap. Additionally, we utilize closed-loop recycling for metal chips and cooling fluids, helping our customers meet their ESG goals.
Modern procurement teams prefer unified suppliers to reduce logistics complexity. By integrating forging, investment casting, precision CNC machining, surface treatment, and clean-room sub-assembly under a single quality system, we help clients simplify their supply chains.
