Learn MoreEstablished in 1996 as a specialized family-owned business, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has evolved into a premier owner-managed SME corporation focusing on advanced metallurgy, casting, and precision machining. Located strategically within the Ningbo Jiangbei Industrial Zone, our facility offers rapid logistical access, positioned within a three-hour transit network of Shanghai International Airport via high-speed rail.
Our operations span a massive industrial footprint, featuring a 16,000 square meter production floor paired with an additional 11,000 square meters of ongoing engineering construction. Today, our highly trained team consists of 130 dedicated personnel, of which 80 run our heavy manufacturing lines, and 50 are cross-functional specialists working in product development, engineering, quality assurance, and global supply chain management.
Over nearly three decades, we have honed our manufacturing capabilities to deliver high-integrity engineering. We possess an outstanding portfolio of technologies including high-precision CNC machining, hot aluminum alloy forging, wax die stainless steel casting (lost wax investment casting), extrusion, structural stamping, and advanced anodizing and electropolishing surface treatments. Customers globally trust us not only for our compliance with rigorous international standards but for our drive toward process innovation.

Friction press capabilities scaling up to 1000 tons. Ideal for safety-critical structural applications requiring elimination of internal gas porosity.
Also known as investment casting. Perfect for complex three-dimensional geometries, sculpture restoration, and flow control pump housings.
We process steel, high-performance alloys, copper, and engineering plastics with press sizes ranging from 5 tons to 250 tons.
In-house advanced chemical anodizing and electrochemical polishing (E-polish) that optimizes corrosion resistance and aesthetic finishing.
50 engineers dedicated to design optimization, metallurgical formulation, DFM (Design for Manufacturability), and risk assessment.
The lost wax casting (investment casting) method is a foundational technology at XinYe. Originally a historical method for creating timeless bronze sculptures, today it is a high-technology industrial science. In the realm of industrial applications, "lost wax casting sculpture" refers to the manufacturing of complex, organic, and ultra-smooth flow-control and artistic metallic designs where standard machining is physically impossible.
Industrial and Aesthetic Localization Application Scenes:
By leveraging silica sol binding agents rather than low-grade water glass, our lost wax foundry achieves a vastly superior surface finish (Ra 3.2 to Ra 1.6 microns) and prevents micro-fissuring inside the casting core. This ensures that the finished sculptures and components have superior mechanical properties and are capable of passing non-destructive testing (NDT).
From initial design iteration to international secure packaging, every phase of production is thoroughly documented and tracked.
Review engineering prints, calculate raw materials, formulate tooling models, and issue commercial quotes.
Build the wax injection molds, run test casting cycles, and verify dimensions on our multi-axis CMM machine.
Send samples with comprehensive inspection reports (material certificate, FAI dimension reports) to the customer.
Initiate multi-cavity production, post-process machining, surface treatments, and inline quality control steps.
Implement final batch audits, load custom export crates, and provide a full one-year warranty against defects.
Our high-capacity assembly workshop facilitates seamless integration of multi-part castings and electronics.
In modern manufacturing, proximity is power. Ningbo Jiangbei Industrial Zone is located in one of the most mature industrial and logistical clusters globally. This regional cluster offers massive downstream supply chain advantages:
To guarantee repeatable, defect-free metal processing, we continuously invest in high-end machinery imported from Japan and Europe.
Friction presses and column hydraulic systems ranging from 300 to 1000 tons. Equipped with precise thermal profiling heaters.
High-speed milling and turning centers capable of executing complex 3D toolpaths with high repeatability.
Coordinate Measuring Machines (CMM), spectroscopic gas analyzers, and roughness meters to verify surface finishes.
Gain insight into our casting pipelines, multi-axis automated CNC operations, and detailed assembly work floors. This video shows our scale, workflow compliance, and high level of operator training.
Check out our precision machining setups (such as the TIPAS Machine h65TMY) executing automated milling on high-grade alloys, ensuring consistency for safety-critical components.
Quality is not checked at the end of the line; it is engineered into every stage of our production process, from metallurgy to final packaging.
Verifies chemical compositions of alloy batches before pouring to ensure raw material compliance.
Coordinate Measuring Machine validates geometrical coordinates and tolerances down to ±0.001mm.
Optical scanning system that measures complex geometric shapes and micro-features.
Spring tension and compression machinery to verify elasticity, yield strength, and structural fatigue resistance.

View DetailsAs industrial demands transition toward intelligent manufacturing and light weighting, XinYe is executing a long-term technology road map:
1. AI-Driven Casting Flow Simulations: We are integrating fluid-dynamics software to predict turbulence and solidification behavior during the lost wax pouring process. This will significantly reduce structural defect rates to single-digit PPM levels.
2. Hybrid 3D Wax Printing: For custom sculptures, prototypes, and low-volume aerospace components, we are adopting direct 3D wax printing. This allows us to bypass initial tooling costs and compress sample lead times from 20 days to 72 hours.
3. Advanced Automation: We are introducing robotic shell-building lines to maintain consistent silica sol coating thicknesses, reducing variability caused by human handling.
Answers to common questions about our capabilities, lead times, pricing, and casting processes.
We cast and machine a wide range of metals, including stainless steel (304, 316, 410), carbon steel, structural alloys, copper, aluminum alloys (both hot forged and die cast), and engineering plastics. We also process specialized materials like 42CrMo and NM400 for high-wear industrial applications.
Typically, sample manufacturing takes about 7 days, depending on tooling requirements. Mass production lead times range between 20 to 30 days after receiving the deposit and drawing approvals. We are always willing to accommodate urgent customer schedules where possible.
Every batch of raw metal is verified using our Italian-designed GNR Spectrum Analyzer before pouring. We offer full material traceability and furnish chemical test certificates and physical dimension reports with every shipment.
We maintain a minimum order requirement for international shipments to ensure production line efficiency. Please contact our engineering department with your project details, and we will tailor a production strategy to your volume requirements.
