Unlocking complex geometries, microstructural integrity, and tight dimensional tolerances for demanding critical environments.
Investment casting, universally categorized as lost wax casting, stands as one of the most reliable and technologically sophisticated metal forming processes available in modern engineering. By coating a detailed wax pattern with a high-performance refractory ceramic slurry, engineers can create a seamless, high-integrity mold capable of holding molten alloys at extreme temperatures. This allows the production of parts with complex cross-sections, internal cooling channels, and complex surface textures that are practically impossible or highly cost-prohibitive to fabricate through mechanical milling, stamp forming, or traditional sand casting methods.
For procurement professionals, global tier-1 supply directors, and engineers in high-stakes fields like aerospace propulsion, automated medical systems, subsea petro-gas installations, and high-performance vehicle components, sourcing components from qualified manufacturers is critical. Selecting a manufacturer with fully integrated manufacturing, testing, and machining capabilities determines whether your system functions reliably in the field or fails catastrophically under cyclic load.

Our company's manufacturing footprint spans 16,000 square meters of production floor, coupled with 11,000 square meters of specialized building construction. Our production structure houses advanced metal forming lines, heat-treatment installations, clean surface treatment pools, and an assembly workshop.
With 130 dedicated personnel, XinYe maintains a robust staffing dynamic: 80 highly-skilled shopfloor technicians and operators, and 50 specialists focusing on R&D, product engineering, quality control, and executive management. This ensures deep attention to detail on every custom inquiry.
Integrated manufacturing services combining investment casting, hot forging, stamping, and post-machining under one roof.
Our core investment casting system produces high-grade stainless steel castings with intricate structures, thin walls, and complex interior pathways. We cast carbon steels, alloy steels, and superalloys utilizing high-grade wax molds and specialized silica-sol processes.
We forge critical aerospace, automotive, and industrial components utilizing high-capacity friction press systems. Our forging delivers grain-aligned, high-density parts with superior mechanical properties under extreme cyclic fatigue loads.
Equipped with 4-axis CNC machining centers, precision turning machines, and advanced milling stations, we turn raw castings or forgings into finished components with dimensional tolerances as tight as 0.001mm.
We process steel, alloy, copper, and specialized plastics utilizing high-precision progressive punching press machines. This setup supports deep-drawn geometries, electrical contacts, housing brackets, and high-volume structural assemblies.
Our finishing operations feature in-house anodizing lines and electrochemical polishing (E-polish). We also provide passivating, powder coating, sand-blasting, and plating to deliver surface finishes for clean-room medical or outdoor operations.
High-precision machinery imported from Japan and optimized production lines running up to 24/7 schedules.
Our factory operates with core equipment imported from Japan to guarantee machining reliability. This capital investment allows us to handle heavy components, complex profiles, and micro-machining with equal ease.
Our factory default schedule runs 6 days per week with 16 hours of daily operations. To accommodate massive commercial programs, we can scale our operation into a full 24/7 production mode within 30 days.








Engineered components deployed worldwide across demanding industries like aerospace, safety detection, and food processing.
Our specialized fire and toxic gas safety detection enclosures, flame sensors, and hydrant pit box enclosures are built to withstand corrosive atmospheres in chemical refineries, mining shafts, and oil & gas rigs.
High-integrity parts including turbine inlets, compressor rotor vanes, structural gearboxes, transmission parts, and structural brackets. Every part undergoes non-destructive testing (NDT) to ensure zero porosity.
Forged suspension knuckles, steering columns, aluminum hot-forged e-bike connector tubes, structural motor brackets, and control levers. Optimized for high strength-to-weight ratios to maximize battery efficiency.
Sanitary grade stainless steel cream whippers, cooking stoves, dispensing valves, and processing pump housings. Mirror-polished surfaces prevent microbial buildup and ensure compliance with strict hygiene regulations.
Why global manufacturing leaders leverage our localized metal cluster and deep logistical integration.
In today's unpredictable economic environment, supply chain stability is just as critical as mechanical performance. Ningbo, China is a global hub for metallurgical manufacturing. This proximity provides XinYe with immediate, cost-effective access to premium alloy suppliers, tooling fabricators, and specialized testing labs. For our international customers, this translates to faster turnaround times, lower material logistics overheads, and a highly agile response to sudden demand increases.
Our location in the Ningbo Jiangbei Industrial Zone is within three hours of Shanghai Pudong International Airport. It is also close to the Port of Ningbo-Zhoushan, the world’s busiest port by cargo tonnage, ensuring reliable global shipping routes.
We source raw metals directly from large domestic mills with verified heat numbers. We maintain a raw material inventory cushion of key grades (such as AISI 316L, 304, 4140, and Al6061) to insulate clients from spot-market price volatility.
Operating out of our 16,000m² facility, our default 16-hour daily shift can expand to 24/7 coverage. We have reserved adjacent land for expansion, allowing us to ramp up capacity when needed.
