Explore our core engineering segments. We deliver end-to-end custom metal fabrication, CNC machining, and complex stamping for rigorous global industry applications.
Founded in 1996 as a family business, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has grown into an owner-managed, high-technology SME corporation. Positioned strategically within the Ningbo Jiangbei Industrial Zone, our facility is within a 3-hour journey from the Shanghai International Airport via high-speed train network.
Covering a total production area of 16,000 square meters with an additional 11,000 square meters of planned construction, our facilities host 130 dedicated personnel, of which 80 run our heavy production floors and 50 lead engineering design, product development, quality control, and management functions.
We deliver an integrated engineering portfolio encompassing: Precision CNC Machining, Aluminum Alloy Forging, Wax Die Stainless Casting, Aluminum Extrusion, Precision Stamping, and Surface Treatments (Anodizing and Electropolishing). We are deeply committed to driving customer success through technology, advanced machinery, and rigorous quality systems.
Understanding the macroeconomic and technical landscapes driving the procurement of high-performance extruded aluminum heatsinks.
As microprocessors, IGBT modules, high-power LEDs, and electric vehicle (EV) drivetrains shrink, localized heat density escalates. Extruded aluminum heatsinks with tailored alloys like AL6063-T5 or AL6060 offer thermal conductivity rates up to 201 W/m·K, satisfying extreme cooling requirements.
International procurement teams in North America, Europe, and Asia demand manufacturing sources that mitigate geopolitical risks, guarantee strict raw material pedigree, and possess certifications such as ISO 9001:2015 and SA8000 for social accountability.
Off-the-shelf thermal components rarely meet advanced electronic footprint requirements. The contemporary demand centers on custom tooling, precise fin-density geometry, custom hollow profiles, and exact CNC machining (tolerances within ±0.005mm) for direct-die contact surfaces.
How our extruded aluminum heatsinks and engineering solutions serve critical industrial applications globally.
For electric vehicle (EV) traction inverters, battery management systems (BMS), and on-board chargers (OBC). We manufacture highly complex, lightweight extruded thermal panels and enclosures that withstand continuous mechanical vibrations while maintaining optimal thermal contact and structural integrity.
Used extensively in industrial gas safety systems, flame sensors, toxic gas detection housings, and explosion-proof control boxes. High-durability finishes (including anodizing and hard-coat protection) ensure chemical resistance in demanding marine, oil and gas, and mining environments.
Surgical, diagnostics, and patient monitoring devices require silent, fanless, highly reliable cooling. Our heatsinks achieve precise dimensional flatness (<0.02mm) for perfect thermal interface mating, keeping noise levels at zero and eliminating dust accumulation risks.
Supporting high-frequency 5G base stations, server power distribution boxes, and industrial networking hubs. Our extrusion profiles are optimized with specialized high-aspect-ratio fins, improving air convection efficiency and thermal radiation surface areas.
The convergence of artificial intelligence, high-performance computing, and electrification demands cooling architectures that exceed standard industrial thresholds. Our engineering department is actively pursuing next-generation solutions:
Our technologies enable us to engineer complete parts, from raw billet to finished, anodized custom assemblies.
Equipped with imported 4-axis machining centers, high-speed CNC turning, and precision milling. We machine complex heatsink geometries, sensor housings, and structural parts with tolerances down to ±0.005mm.
Using friction press machines from 300 to 1000 tons and column hydraulic machines from 100 to 630 tons. Hot forging provides high density, high mechanical strength, and pore-free structures for critical safety components.
For complex shapes and high-strength corrosion-resistant parts, our investment casting (lost wax) process handles thin-walled, high-definition structural elements for aerospace and fluid management.
High-capacity lines for custom extrusions alongside punching presses (5 to 250 tons) for high-volume stampings and deep-drawn copper, steel, and aluminum electronics enclosures.
In-house professional surface finish applications including chemical cleaning, fine bead-blasting, professional anodizing (clear, black, and custom colors), and electropolishing for high corrosion resistance.

For industrial B2B clients, quality is not a variable; it is the absolute foundation of corporate longevity. Supported by our international clients, we have developed a rigorous, trace-documented inspection loop. Beginning at raw material ingestion and tracing every stage of the production floor, we verify material conformity, dimensional precision, and structural integrity.
Our quality management is certified to ISO 9001:2015 and SA8000 standards, ensuring both systematic quality assurance and social compliance. We provide complete material test certifications, CMM layout maps, and spectral alloy reports with every production batch shipped.
From initial design evaluation to secure global logistics, we optimize each phase to maintain quality, reduce lead times, and control costs.
Customer provides 2D/3D engineering drawings. Our engineering team reviews specifications, identifies potential thermal or mechanical optimizations, confirms tolerances, and provides detailed cost calculations covering materials, tooling, and secondary processing.
Custom tooling is designed and manufactured. Initial test extrusions are conducted to optimize alloy flow. Samples are processed, finished, and verified through our internal laboratory. We issue a comprehensive inspection report (FQR) alongside the physical prototypes.
Customers test the prototype in their specific device context. If thermal dissipation, clearance tolerances, or assembly properties need adjustments, our technicians revise the extrusion profiles and CNC coordinates to align perfectly with your performance requirements.
Following prototype approval, we initiate full-scale production. We establish statistical process controls (SPC) at multiple key points. In-line measurement runs regularly to ensure dimensional compliance. Custom surface finishes like anodizing are applied under clean-room conditions.
Finished goods undergo final quality assurance checks. We utilize custom-engineered structural packaging to prevent surface abrasion or fin deformation during international shipping. We prepare all necessary custom clearance documentation, certificate of conformance (CoC), and origin details.
At Xinye, we believe engineering is defined by responsibility. We align our manufacturing actions with three primary operating values:
Trust First: "Our primary responsibility is to exceed the technical and logistical expectations of our partners with absolute transparency."
Total Solutions: "We do not simply execute drawings; we analyze the mechanical assembly, material compatibility, and cost efficiency to provide a total structural solution."
Continuous Innovation: "We invest in training our employees and keeping our manufacturing tools at the absolute standard of global industrial practice."
