Preserved primary technical products featuring high-precision metal finishing, CNC optimization, and advanced casting services.
In the modern manufacturing landscape, industrial metal finishing is no longer simply about aesthetics. Global OEMs and assembly plants require robust protection to meet harsh operating conditions. Anodized coatings—especially for aluminum alloys—have transitioned toward eco-friendly chemistries (such as trivalent chrome sealing processes) that fully comply with stringent RoHS and REACH directives.
As a core surface process, anodizing creates an integrated, oxide-based layer that is physically part of the aluminum substrate. This layer offers unparalleled corrosion protection, electrical insulation properties, and a hardness layer capable of resisting mechanical wear. Industrially, Type II (Sulfuric Acid Anodizing) is preferred for aesthetic and moderate wear components, while Type III (Hardcoat Anodizing) provides a deeper, highly dense oxide layer designed for rigorous defense, aerospace, and oil exploration equipment.
Our engineering team works directly with global tier-1 supply lines to guarantee uniform oxide thickness, exceptional die penetration, and complete sealing stability. By integrating multi-axis CNC machining, hot forging, and automated anodizing operations under one unified facility, we mitigate contamination risks while reducing transit times for global sourcing groups.
Ningbo Jiangbei XinYe Metal Works Co., Ltd. was established in 1996. Initially founded as a family-run business, we remain an owner-managed SME corporation dedicated to the highest levels of quality, safety, and technological agility.
Located within the Ningbo Jiangbei Industrial Zone, our facility is within a 3-hour high-speed train connection from Shanghai International Airport, offering ideal logisitical support for international clients. Of our 130 team members, 80 are dedicated production professionals operating specialized machinery. The remaining 50 engineers, product developers, and quality control experts govern our project execution, global supply chain, and compliance architectures.
We offer comprehensive expertise across a broad range of processing sectors: CNC machining, aluminum alloy hot forging, lost wax stainless steel casting, extrusion, metal stamping, and specialized surface treatment (including anodizing and electrochemical polishing).
Our customers choose us because of our engineering standards and drive for continuous technological innovation. With over 20 technical patent certificates and certified quality workflows under ISO 9001:2015 and SA8000 (Social Accountability Standard), we guarantee structured corporate compliance, verified product safety, and zero compromises on mechanical integrity.

XinYe operates on a standard schedule of 16 hours a day, 6 days a week. When production volumes require it, we can scale our operation to full 24/7 mode within 30 days. We also retain additional land zoned for expansion, ensuring we can grow alongside your project requirements.
For high-accuracy shaft-turning and secondary operations, we leverage advanced machinery like the TIPAS h65TMY. This guarantees tight concentricity and smooth surface finishes before components proceed to the electrochemical anodizing tank.
Quality is the foundation of our work. With customer support, we have built a strict quality control system from raw material verification to final delivery.
Quality begins before manufacturing. Incoming alloys undergo structural inspection to confirm correct composition. During production, in-process quality control points monitor dimensional accuracy, surface condition, and anodizing thickness. Once manufacturing is complete, we perform final verification using CMM, spectrum analysis, and roughness testing to ensure all products comply with design specifications.
Detailed quality documentation—including Material Certificates, Chemical Analysis Sheets, CMM Inspection Reports, and Coating Thickness Declarations—accompanies every shipment.
Performs chemical checks on raw materials to verify alloy chemistry before casting or forging.
Ensures high dimensional accuracy by checking component dimensions against CAD models.
Checks geometries of complex parts, stamping structures, and deep drawn walls.
Secondary video system optimized for verifying smaller components and internal cavities.
Measures surface roughness (Ra) to ensure finishes meet industrial design specifications.
Verifies structural yield strength and compression limits under mechanical loads.
From initial design files to final component delivery, we maintain a clear, documented path for every project.
Includes detailing custom OEM samples, engineering drawing reviews, pricing updates, and lead time planning.
Includes drawing calculations, alloy sourcing, sample run setups, and initial inspection reporting.
We work directly with customers to evaluate samples and make any necessary adjustments before starting volume production.
Once samples are approved, mass production begins with integrated quality checks, final packing, and logistical delivery.
We provide a one-year warranty against manufacturing defects and offer post-delivery support through our dedicated assembly workshop.
