Providing high-precision component manufacturing for global buyers with strict dimensional and surface requirements.
Investment casting, widely known as lost wax casting, is an advanced manufacturing technique designed to produce highly detailed components with exceptional surface finishes and precise dimensions. When working with high-performance aluminum alloys, this process offers significant advantages over sand or die casting methods. It minimizes the need for extensive post-process machining and enables designers to create complex internal geometries that are otherwise impossible to produce.
At Ningbo Jiangbei XinYe Metal Works Co., Ltd., we combine the traditional lost wax process with modernized computer-aided flow simulations, automated ceramic shell coating procedures, and precise temperature-controlled environment settings. This hybrid process minimizes internal gas porosity and controls dendrite arm spacing (DAS), resulting in castings with optimal tensile and yield strength, ideal for heavy-duty components.
Owner-managed metal fabrication specialists delivering certified, high-precision engineering services since 1996.
Founded in 1996 as a family-run enterprise, Xinye has grown into a highly specialized, owner-managed SME corporation. Located in the Ningbo Jiangbei Industrial Zone, our facility is strategically positioned for rapid international export, just three hours from the Shanghai international airport via China's high-speed rail network.
Our operation covers a total area of 16,000 square meters of production space, with an additional 11,000 square meters currently under construction to accommodate our growing technological capabilities. Our dedicated team of 130 professionals includes 80 skilled production specialists and 50 personnel focused on product development, quality control, logistics management, and advanced engineering.
We provide a comprehensive, one-stop service path. From initial raw materials testing to precision 4-axis CNC machining, hot forging, lost wax casting, and advanced surface anodization or electrochemical polishing treatments, we maintain total control over every step of the production process.
Why international companies choose Ningbo industrial clusters for customized metal casting and machining services.
Ningbo is a global hub for metal fabrication. Sourcing within this industrial cluster gives us immediate access to raw material refineries, specialized heat-treatment plants, and tooling suppliers. This localized network reduces logistics delays and minimizes overhead costs.
We lower the Total Cost of Ownership (TCO) for international buyers. Through in-house tooling creation, rapid prototyping, and automated operations, we amortize initial engineering costs and provide stable, competitive prices even during raw material market fluctuations.
We prioritize social accountability. Our SA8000 certification ensures clean, safe working environments and ethical labor practices. This minimizes supply chain risks and helps global buyers meet their ESG (Environmental, Social, and Governance) requirements.
Combining traditional lost wax casting with modern post-machining and surface treatment capabilities under one roof.
Our core capabilities have evolved alongside the changing requirements of our international customer base. Today, we offer more than just basic manufacturing; we provide custom product development, mold design, prototyping, and large-scale manufacturing services.
Our core manufacturing processes are optimized for precision, structural integrity, and repeatability:
Delivering certified components for demanding operating environments across various sectors.
We manufacture critical components for gas and fire detection devices, explosive sensor housings, toxic gas detectors, and hydrant pit box enclosures. These parts are engineered to withstand extreme pressures and prevent spark generation in explosive atmospheres.
We supply turbine inlets, transmission component parts, and structural brackets. Our manufacturing processes focus on eliminating micro-porosities and grain alignment issues to meet strict aviation safety and performance criteria.
We manufacture lightweight transmission enclosures, brackets, and structural components for electric bikes, including high-strength connector components, structural tubes, and control levers. These parts support the automotive industry's focus on weight reduction.
We manufacture sanitary tabletop cooking stove components and domestic cream whipper parts. These components are designed with smooth surfaces for easy cleaning and are compatible with food-safe coatings.
Using high-precision machinery imported from Japan to ensure consistency across large production runs.
To meet high quality and efficiency standards, our facility uses advanced production machinery designed for complex, multi-stage metal processing:
Our standard operations run 16 hours a day, 6 days a week. When required, we can scale to 24/7 continuous operations within 30 days. We also maintain additional development space for expanding our production capacity to meet long-term customer contracts.
Xinye has achieved ISO 9001:2015 and SA8000 certifications to ensure reliable product quality and professional service.
Our quality control process starts with inspection of incoming raw materials. Every batch of aluminum alloy, steel, or copper undergoes verification to confirm chemical composition and physical properties before it enters production.
During manufacturing, we use in-process checkpoints to monitor dimensions and detect surface defects. The final step involves a comprehensive inspection before packaging, with all measurements logged in our traceability files.
Our testing department utilizes specialized measuring instruments to verify dimensional accuracy and material integrity:
A structured process designed to transition customer specifications from design files into approved production parts.
The process begins with initial contact, where clients provide detailed mechanical drawings, engineering 3D CAD files, and materials specifications. We review these details to align on tolerance expectations, sample quantities, shipping requirements, and production lead times.
Our engineering team reviews the technical documentation, calculates tooling geometries, and outlines the manufacturing plan. We prepare a detailed commercial quotation covering raw materials, tooling costs, and production cycles. Upon agreement, we produce initial sample molds and casting shells to build test parts.
Samples undergo dimensional inspection and composition testing. We deliver these samples to the customer alongside a complete inspection report and material certification for review and approval.
After sample approval, we begin full-scale manufacturing. We organize production schedules, schedule machine time, and perform in-process quality audits. The finished items are then packed using protective materials to prevent transport damage.
We provide after-sales support with a one-year warranty covering manufacturing defects. We also offer dedicated assembly services within our workshop for products requiring multi-component configuration before final delivery.
