Ningbo Jiangbei XinYe Metal Works Co., Ltd. — Your Trusted Manufacturing Partner Since 1996
Ningbo Jiangbei XinYe Metal Works Co., Ltd. was established in 1996 as an owner-managed SME corporation. Over the past 28 years, we have transitioned from a localized family business to a globally recognized custom metal fabrication supplier. Our company operates inside the Ningbo Jiangbei Industrial Zone, situated strategically within a 3-hour commute from Shanghai Pudong International Airport via China's high-speed rail network.
Today, our company covers 16,000 square meters of production floor, with an additional 11,000 square meters allocated for ongoing expansion. Out of our 130 highly specialized employees, 80 manage active floor production, while 50 are dedicated to product development, engineering, quality assurance, and global supply chain operations.
We are certified to both ISO 9001:2015 and SA8000 (Social Accountability) standards. This certification matrix ensures our global B2B clients receive consistent product quality, ethical labor compliance, and transparent operations.
Detailed analysis of B2B procurement criteria, manufacturing processes, and technological trends shaping investment casting.
Lost wax casting (historically termed investment casting) remains a critical manufacturing method for complex metal geometries. Unlike conventional sand casting or mechanical machining, lost wax casting produces parts with intricate details, thin walls, internal undercuts, and smooth surface finishes (typically Ra 3.2 to Ra 1.6 μm for silica sol castings). By melting away the wax pattern, manufacturers can cast high-melting-point alloys—including stainless steel, cobalt superalloys, carbon steels, and specialized aluminum alloys—without draft angles, minimizing the requirement for post-cast processing.
For B2B procurement departments in fields such as aerospace, oil and gas, safety infrastructure, and high-performance automotive, investment casting provides a balance of structural strength and design freedom. Components such as turbine blades, valve bodies, safety sensor housings, and transmission mounts require minimal secondary machining, reducing scrap metal rates and overall production costs.
The global metal fabrication supply chain relies heavily on Chinese manufacturing clusters, particularly in Ningbo. This preference is driven by supply chain integration, technical expertise, and cost efficiencies:
Procuring investment castings requires a clear understanding of process tolerances and technical criteria. At XinYe, we maintain standard tolerances according to the international ISO 8062 SF (investment casting) standard (typically CT4 to CT6 for silica sol castings). Our engineering team advises buyers to consider the following parameters when drafting an RFQ:
The investment casting sector is shifting toward digital manufacturing. Key changes include:
A comprehensive overview of our engineering portfolio, machining equipment, and global target markets.
We specialize in silica sol investment casting for stainless steel, carbon steel, and alloy steels. Ideal for complex shapes with thin-walled geometries requiring clean surface textures and precise dimensional tolerances.
Our facility houses CNC machining centers with 4-axis control, CNC turning machines, and milling systems. We achieve finish machining tolerances up to ±0.005 mm on cast, forged, or raw billet materials.
Using hot friction presses with capacities from 300 to 1,000 tons, we manufacture high-density forged aluminum components. This method improves mechanical properties by refining the internal grain structure.
Equipped with hydraulic presses up to 630 tons and punching machines from 5 to 250 tons, we shape steel, copper, and alloy parts with high repeat accuracy.
We provide chemical and electro-chemical surface processes, including anodizing, electropolishing, sandblasting, powder coating, zinc plating, and passivation to improve corrosion resistance.
Our manufactured parts are widely used across the following industrial sectors:
From initial design evaluation to final delivery, we trace every step to ensure dimensional accuracy and material integrity.
We review technical drawings, calculate manufacturing costs (tooling, casting, machining, surface treatments), and provide a detailed quotation.
We fabricate precise tooling, inject wax patterns, and pour initial metal samples. We verify the dimensions and compile a full material certificate.
Clients test the physical samples within their assembly lines. We collect feedback on dimensions, surface finish, and tolerances before mass production.
After sample approval, we initiate volume manufacturing. Quality gates are set at injection, shell building, pouring, machining, and packaging phases.
We provide a one-year warranty covering manufacturing defects. We also offer mechanical sub-assembly in our specialized clean workshop.
Our core machining and forming machinery is imported from Japan and Europe to maintain high repeat accuracy.
Capacity range from 300 to 1,000 tons. Offers precise temperature control for forging aluminum structural alloys.
Multi-axis CNC turning and milling centers capable of finishing castings and forgings to tight mechanical tolerances.
Includes a CMM measuring machine, GNR Spectrum Analyzer, Video Measuring System, and Surface Roughness Tester.

Factory Hours: We operate 6 days a week, 16 hours a day, and can scale to a 24/7 schedule within 30 days based on volume requirements.
Quality is the foundation of our work. From raw materials to finished products, every stage is checked and documented.
Our quality department checks incoming raw materials using a GNR Spectrum Analyzer to verify chemical composition before casting. Every batch is assigned a tracking number to trace components back to the raw heat melt.
For dimensional inspection, we use a Coordinate Measuring Machine (CMM) and a Video Measuring System. These tools verify critical dimensions against client CAD models, checking positions, circularity, concentricity, and thread configurations.
Additionally, we measure structural characteristics using a Roughness Meter to verify surface profiles, and a Spring Tension/Compression Testing Machine to check dynamic mechanics.
