Explore our structural manufacturing portfolios, combining advanced lost wax investment casting, hot alloy forging, and multi-axis CNC finishing.
Ningbo Jiangbei XinYe Metal Works Co., Ltd. was established in 1996 as an owner-managed family enterprise. Over nearly three decades, we have transitioned from a localized tool and die shop into a highly sophisticated, technology-integrated global supplier of precision metal components. Today, we are structurally optimized as a medium-sized enterprise, managing an expansive production footprint of 16,000 square meters, with an additional 11,000 square meters of construction and logistics land reserved for scaling capacity.
Our operation is located in the Ningbo Jiangbei Industrial Zone, a premier logistical hub that offers direct access via China's high-speed rail network, situated within 3 hours of Shanghai International Airport. Our corporate strength lies in our integrated workforce of 130 skilled employees. Our structure features 80 dedicated production operators and 50 specialists in product development, engineering, quality control, and management. This enables us to maintain an exceptional engineering-to-operator ratio, fostering innovation and robust quality assurance.
We provide comprehensive solutions across multiple manufacturing lines, including CNC Machining, Aluminum Alloy Hot Forging, Wax Die Stainless Steel Casting (Investment Casting), and sheet metal fabrication via extrusion and stamping, accompanied by precision finishing treatments such as anodizing and electrochemical polishing (E-polish).
A analytical outlook on how investment casting acts as the cornerstone of mission-critical engineering applications worldwide.
Wax investment casting—often termed the "lost wax" process—remains the gold standard for producing highly complex, net-shape components that are difficult or impossible to construct through conventional machining or alternative casting methods. Valued for its ability to deliver superior surface finishes, intricate internal geometries, and tight dimensional tolerances, the global market for investment casting is seeing steady growth, driven by key demand sectors in aerospace, medical devices, automotive propulsion, and energy exploration.
Modern industrial design trends place a heavy emphasis on weight optimization, thermal resistance, and high strength-to-weight ratios. As a result, global engineering is moving away from basic cast irons toward high-performance materials like stainless steels, titanium alloys, and nickel superalloys. Wax investment casting allows for the processing of these advanced materials with minimal scrap, which is critical when dealing with costly metals. Ningbo Jiangbei XinYe Metal Works Co., Ltd. addresses this shift by combining our wax die stainless steel casting line with downstream multi-axis CNC finishing, providing a single-source solution for these demanding materials.
China has solidified its position as a central player in the global investment casting sector, transitioning from high-volume production to advanced, high-precision engineering. By combining competitive tooling costs, integrated material supply chains, and advanced processing technology, Chinese manufacturers like XinYe Metals offer international buyers a reliable route to bring new products to market efficiently. This structural advantage allows us to support customers from initial prototyping through to serial production, helping to streamline global supply chains.
Our strategic plan for integrating digitization, automation, and advanced metallurgy into our casting processes.
To maintain our competitive edge in the global manufacturing market, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has established a technical roadmap focused on high precision, material efficiency, and environmental sustainability.
Our R&D team works to refine the casting process to achieve true "near-net-shape" results. By improving mold design and slurry coating methods, we aim to minimize the amount of post-cast machining required, which helps lower material waste and overall production costs for our customers.
We are updating our manufacturing processes to meet modern environmental standards. This includes adopting water-based binder formulations in place of traditional solvent-based materials to lower VOC emissions. Additionally, we use advanced steam autoclaves to reclaim and recycle wax, minimizing raw material waste.
For components with complex geometries and tight tolerance requirements, casting alone is often not enough. XinYe bridges this gap by combining our casting line with 4-axis Japanese CNC machining centers. This allows us to achieve tolerances within 0.001mm on critical mating surfaces, providing a reliable option for aerospace and automotive parts.
A closer look at our machinery, designed for precision metal fabrication, casting, forging, and finishing.
We specialize in lost wax investment casting, focusing on stainless steels, carbon steels, and copper-based alloys. This process is designed to deliver fine surface finishes and complex internal pathways.
Utilizing friction presses with forces from 300 to 1,000 tons and column hydraulic presses from 100 to 630 tons, we manufacture high-density parts with optimized grain structures.
Our facility is equipped with 4-axis Japanese CNC machining centers, turning centers, and milling machines, allowing us to perform precision post-cast machining on complex components.
We operate stamping presses from 5 to 250 tons, working with steel, aluminum alloys, copper, and specialized plastics to produce stamped and deep-drawn parts.
We provide in-house finishing options, including anodizing, chemical conversion, sandblasting, and electrochemical polishing (E-polish), ensuring components are ready for assembly.
Our default operations run 16 hours a day, 6 days a week, with the ability to scale to a 24/7 run-time within 30 days to accommodate sudden demand spikes. Our facilities are designed to allow for expansion as customer volume grows.
A transparent look at how we manage customer orders from initial design through to final delivery.
We review customer drawings (2D/3D), clarify requirements, establish target tolerances, and finalize lead times.
We source materials, manufacture tooling, cast prototype parts, and generate initial dimensional reports.
Samples and testing documentation are sent to the customer for review, feedback, and formal approval.
Upon approval, we schedule bulk production, monitor quality at key stages, and complete post-processing.
We conduct final inspections, package parts securely for transport, and provide complete documentation.
Our quality control system spans every stage of production, from raw material verification to final inspections. This focus on consistency has helped us earn both ISO 9001:2015 and SA8000 certifications, helping to ensure that our processes meet both customer and regulatory standards.
To support our quality assurance team, we maintain an on-site laboratory equipped with testing instruments, allowing us to perform chemical analysis, mechanical testing, and dimensional inspection in-house.
