Our Core Manufacturing Technologies

Providing custom industrial solutions through a robust and fully integrated range of engineering capabilities.

CNC Precision Machining

Equipped with advanced 4-axis control vertical and horizontal machining centers. We achieve dimensional accuracies down to 0.001mm to meet the tightest global tolerance specifications.

  • High-precision multi-axis milling & turning
  • In-house tooling and fixture engineering
  • Post-casting high-accuracy secondary processing

Aluminum Alloy Forging (Hot)

Leveraging friction press forces from 300 to 1000 tons alongside column hydraulic systems (100t to 630t) for high-density, grain-oriented industrial forged parts.

  • High mechanical performance structure
  • Elimination of internal voids and gas porosity
  • Perfect grain flow orientation for dynamic load parts

Wax Die Stainless & Alloy Casting

Our flagship lost wax foundry employs refined silica-sol investment casting systems to output intricate geometries in high-alloy and stainless steel grades.

  • Excellent surface finish (Ra 3.2 - 6.3μm)
  • Highly detailed custom internal structures
  • Near-net shape design versatility for complex parts

Extrusion & Stamping

Processing stamping, deep drawing, and profiles across carbon steel, aluminum alloys, structural copper, and technical grade plastics using dynamic presses (5t to 250t).

  • High-speed stamping and progressive die runs
  • Deep-drawn metal enclosures and structural housings
  • Custom structural aluminum profiles and extrusion

Technology Roadmap & Future Outlook

Pioneering Smart Metallurgy, Automation, and Sustainable Manufacturing Systems.

As a leading wholesale lost wax foundry, XinYe is executing a strategic technical roadmap centered around Industry 4.0 digitalization and green metal manufacturing. We are progressively transitioning our pattern-making phase to support hybrid operations, incorporating high-accuracy additive manufacturing (3D-printed wax models) to shorten prototyping lead times from weeks to 48 hours.

To address the strict zero-defect parameters of modern automotive and aerospace sectors, we are implementing digital twin solidification simulation software. This enables our metallurgy teams to analyze thermal flow profiles, predict and eliminate shrinkage cavities, and design gating systems with high yield efficiency before pouring metal.

  • Intelligent Energy Management: Upgrading our induction melting furnaces with smart power monitoring to reduce carbon footprint per cast ton.
  • Closed-loop Wax Recovery: Enhancing autoclave dewaxing systems to recycle 95% of pattern wax, maintaining stability and resource efficiency.
  • Robotic Shell Coating: Deploying robotic arms in the investment shell building phase to ensure consistent slurry layers and eliminate human error.

China Factory 4.0: Supply Chain Resilience & Geographic Advantage

Combining structural cluster economics with highly optimized manufacturing processes.

Our factory in Ningbo, Zhejiang Province, leverages a deep local industrial cluster. This provides immediate access to high-purity raw materials, heat treatment facilities, and surface treatment sub-suppliers. This physical proximity cuts intermediate transit times to near zero.

Furthermore, Ningbo Port—the world's largest port by cargo throughput—is at our doorstep. This proximity offers multiple maritime logistics lanes, reducing freight costs and customs transit times. In an era of global shipping uncertainty, this ensures a reliable supply chain.

Our facility operates on a standard 16-hour/6-day double shift system. If customer demand increases, we can transition to a full 24/7 continuous production schedule within 30 days. We maintain safety stock levels for strategic alloy ingredients (such as CF8M, 316L, and structural aluminum alloys) to shield global buyers from raw material market fluctuations.

Aerospace & Defense

High-tolerance flight transmission components, aviation fuel hydrant pit boxes, hinge brackets, and turbine inlets. Cast from highly monitored vacuum-induction alloys with full raw material traceability.

Automotive & E-Bike Systems

Transmission housings, structural connectors, dynamic lever assemblies, and drive-unit brackets. We balance lightweight requirements with structural fatigue limits for modern electric mobility.

Food Processing & Medical Appliances

Stainless steel cream whippers, table-top cooking stove rings, valves, and sanitary fittings. Cast with ultra-low carbon stainless steel to guarantee non-contamination and resistance to sanitizing chemicals.

Addressing Global Procurement Demands

Helping procurement directors minimize Total Cost of Ownership (TCO).

Procurement teams faces multiple challenges: balancing unit costs, monitoring quality variance, ensuring shipping reliability, and maintaining compliance. XinYe simplifies sourcing by providing a single point of responsibility.

We manage the entire process, including initial pattern tooling, metallurgy casting, CNC machining, surface finishing (including clear or colored anodizing, chemical blackening, and electrolytic polishing), and final component sub-assembly. This complete cycle limits transit damage, reduces supplier inspection overhead, and cuts customs documentation requirements.

  • Tool Life Guarantee: In-house tooling maintenance is included in our long-term agreements, protecting customers from recurring tooling costs.
  • Flexible Payment Terms: We support major trade payment options, including telegraphic transfers (30% deposit, 70% against Bill of Lading copy) and customized letters of credit.
  • Strict Packaging Standards: Custom heavy-duty export crates, anti-corrosion VCI packaging for ocean cargo, and specialized padding protect finished surfaces.

What is your Minimum Order Quantity (MOQ)?
Yes, we require all international orders to have an ongoing minimum order quantity. For new product developments (NPI), we can support lower-volume pilot runs to assist with qualification processes. Please contact us to discuss your project requirements.
Can you supply the relevant engineering documentation?
Yes, we supply comprehensive documentation package including Certificate of Conformance (CoC), material chemical composition analysis (spectrometer logs), physical property test reports, dimension measurements (CMM inspection reports), heat treatment curves, and Certificate of Origin.
What is the typical lead time?
For initial pre-production sample patterns and physical prototypes, our typical lead time is 7 days. For full-scale mass production, delivery ranges from 20 to 30 days following deposit verification and physical sample approval.
What payment methods do you accept?
We accept standard corporate transactions through direct bank telegraphic transfer (T/T), Western Union, and PayPal. Our typical payment structure is a 30% advance deposit to initiate production tooling, with the remaining 70% balance paid upon presentation of the copy of the Bill of Lading (B/L).
What is the product warranty?
We warranty all materials and workmanship for one full year starting from the delivery note date. If any manufacturing deviations or defects occur, our team will review the issue and arrange for replacement parts or credit adjustments.
How do you guarantee safe delivery?
We use high-quality heavy-duty export packaging, including reinforced wooden crates, moisture-resistant barriers, and vacuum-sealed VCI bags to prevent corrosion during sea freight. If required, we can also accommodate custom packing designs.
What shipping methods do you support?
We offer multiple shipping solutions. For urgent components and pre-production samples, air express (DHL/FedEx/UPS) is recommended. For bulk shipments, sea freight from Ningbo Port is the most cost-effective option. We work with clients to coordinate FOB, CIF, or DDP delivery terms.
