Product Overview：Your Integrated Solution for Precision Copper Castings
Ningbo Shengxu International Co.,Ltd., Ltd. is a leading China-based manufacturer specializing in custom OEM copper valve body casting and machining. We deliver a seamless, start-to-finish manufacturing process, combining expert brass and copper sand casting with high-precision CNC machining under one roof.
Our core expertise lies in producing complex, high-tolerance valve bodies and other copper casting parts. The robust sand casting process is ideal for creating near-net-shape castings, which our advanced CNC workshops then transform into ready-to-install components with exacting specifications for threads, sealing surfaces, and critical dimensions.
We empower global clients in industries like automotive, hydraulics, and marine by providing a comprehensive custom solution—from material selection and DFM (Design for Manufacturability) advice to volume production and rigorous QC—ensuring supply chain efficiency and superior end-product performance.
Key Features & Advantages: Why Partner with NBShengxu?
1. Superior Material Integrity & Performance
● High-Grade Copper Alloys: We use premium brass, bronze, and other copper alloys known for excellent corrosion resistance, anti-bacterial properties, high conductivity, and superior mechanical strength, suitable for various fluids like water, oil, and gases.
● Material Traceability: All raw materials are sourced from certified suppliers with Mill Test Certificates (MTC) provided, guaranteeing consistent quality and full traceability.
2. Advanced Sand Casting Capability
● Expert in Sand Casting: This versatile and cost-effective method is perfect for medium to large-sized, geometrically complex copper valve bodies, accommodating both prototype and high-volume production runs.
● High-Quality Castings: Our foundry techniques yield castings with dense microstructure, minimal internal porosity, and good surface finish, providing an optimal foundation for final machining.
3. Precision CNC Machining Integration
● One-Stop Service: Our in-house CNC machining centers perform all necessary post-casting operations—turning, milling, drilling, and tapping. You receive finished, ready-to-assemble parts, eliminating the hassle of managing multiple vendors.
● Exceptional Accuracy & Consistency: We maintain tight tolerances (down to ±0.02mm) on all critical features, ensuring perfect sealing, leak-proof performance, and easy assembly in your valve systems.
4. Rigorous Quality Control & Assurance
● Full-Process Inspection: We implement a strict QC protocol from mold inspection and First Article Inspection (FAI) to in-process checks and final random inspection.
● Professional Testing Equipment: Our lab is equipped with CMMs, spectrometers, and pressure testing equipment to verify dimensions, material composition, mechanical properties, and pressure tightness against ISO, ASTM, and DIN standards.
5. Unmatched Customization & OEM/ODM Support
● Flexible OEM Service: We specialize in manufacturing according to your drawings and specifications. Our engineering team offers valuable DFM feedback to optimize your design for cost-effectiveness and manufacturability.
● Industry-Proven Experience: We have a deep understanding of the technical requirements for parts used in automotive components, hydraulic systems, marine hardware, and more.
