Direct Factory Pricing on High-Tolerance Components
Established in 1996 as an owner-managed SME family business, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has expanded into a leading industrial force. Conveniently located in the Ningbo Jiangbei Industrial Zone, our facility is situated within a 3-hour commute from Shanghai Pudong International Airport via China's high-speed rail corridor. This strategic geographic proximity offers unmatched logistics and export benefits through the Port of Ningbo-Zhoushan.
Our expansive production footprint covers 16,000 square meters of active manufacturing space, with an additional 11,000 square meters dedicated to construction and future engineering expansions. Backed by a dedicated workforce of 130 skilled professionals—comprising 80 highly trained production technicians and 50 experts specialized in product design, metallurgic engineering, strict quality control management, and customer logistics—we provide reliable OEM and ODM manufacturing services to the global industrial sector.
How our regional cluster and technical capabilities optimize your global supply chain, minimize total cost of ownership (TCO), and guarantee operational resilience.
Sourcing from Ningbo places your business at the center of the world's most integrated metalworking and tooling ecosystem. We guarantee immediate access to premium alloys, custom tooling workshops, heat-treatment installations, and rapid shipping infrastructure. This significantly reduces overall production cycles and internal shipping overheads.
We eliminate the risks associated with multiple multi-tier subcontracting networks. Our capability portfolio ranges from mechanical product development, 3D prototyping, and die tooling fabrication, to volume metal forming (stamping, hot forging, lost wax investment casting), multi-axis CNC finishing, surface treatment (anodizing, polishing), and final product assembly.
We operate in strict compliance with ISO 9001:2015 Quality Management and SA8000 Social Accountability systems. By utilizing advanced inspection technologies including coordinates metrology, spectrometers, and roughness sensors, we verify that every critical tolerance, chemistry requirement, and surface profile specification matches your standards.
How XinYe achieves high dimensional accuracy, surface finishing, and structural integrity for critical industrial applications.
In high-tolerance metal component manufacturing, the term "Silver Wax Casting" (often associated with precious metal detailing or master-pattern wax modifications in stainless and alloy casting) represents a specialized process of investment casting. This technique utilizes master metal models, precision silicon tooling, and specialized wax formulas to prevent shrink deviations during pattern creation. At XinYe, we apply these advanced lost wax casting methods to fabricate components that require complex internal geometries, thin walls, and fine surface profiles, eliminating the need for expensive secondary machining.
We work with a wide range of ferrous and non-ferrous metals to meet custom engineering specifications:

From initial engineering review to final delivery, we maintain a transparent, traceable workflow.
Customers provide engineering CAD files, technical drawings, material specifications, and quality requirements. Our engineering team conducts a thorough Review to identify key process variables, optimizing production cycles and costs before tool building begins.
We develop custom molds and manufacture initial samples. This phase includes detailed dimensional inspections, chemical analysis of trial pours, and mechanical stress test reports. We verify every specification meets customer requirements before moving to mass production.
Prototyped samples, metallurgical inspection files, and dimension records are sent to the client for validation and sign-off. If required, tool path modifications are implemented and re-tested to ensure the final product meets expectations.
Upon approval, we schedule the components for production. Each stage is monitored at designated inspection stations, verifying dimensional stability, surface finish, and mechanical properties. This process provides full production traceability.
We offer specialized post-casting assembly, custom packaging solutions, and a one-year warranty against manufacturing defects. Shipping runs are packed to prevent damage during international transport, with complete documentation provided.
Operating under strict ISO 9001:2015 standards, our quality control lab uses advanced instrumentation to ensure dimensional accuracy and material integrity.
Performs chemical analysis on incoming raw bars and molten heats, verifying alloy composition matches international standards.
Verifies 3D geometric dimensions and coordinate tolerances down to the sub-micron level for precision engineering.
Provides non-contact optical inspection for high-precision checks of micro-profiles and complex features.
Automated optical inspection system designed to verify consistency across volume production runs.
Measures surface finishes on cast, machined, and polished parts to ensure they meet specified micro-inch ratings.
Tests mechanical performance and load limits, verifying structural integrity for heavy-duty applications.
We provide full material traceability and inspection reports for all orders. Our manufacturing processes are certified to ISO 9001:2015 and SA8000 standards, ensuring high quality control and responsible production practices. Whether manufacturing components for healthcare, automotive, or industrial applications, we are committed to meeting our customers' specifications and requirements.
