Precision Copper Components

-- Steady & Reliable Manufacturer --

Advanced Fabrication for High-Tech Industry

Precision copper components are custom-engineered parts that go beyond standard tubing and fittings to meet the exacting needs of the electronics, automotive, and aerospace industries. Copper’s unique combination of high electrical conductivity, thermal efficiency, and ductility makes it an irreplaceable material for specialized components like heat sinks, busbars, electrical terminals, and complex induction coils. At Zhejiang Jingliang, our precision component division utilizes state-of-the-art multi-axis CNC machining, high-speed stamping, and specialized tube-forming technology to create parts with tolerances as tight as ±0.01mm. We work with various copper alloys, including C11000 (ETP) for maximum conductivity and C12200 for thermal applications, to ensure that each component is perfectly suited for its end-use environment.

The value of a precision component lies in its ability to perform in "Mission-Critical" environments. For the Electric Vehicle (EV) industry, we manufacture specialized cooling plates and battery busbars that must manage massive thermal loads while maintaining electrical integrity. In the electronics sector, we produce micro-tubes and intricate heat spreaders used in server cooling. Our fabrication process includes advanced joining techniques such as laser welding, vacuum brazing, and silver soldering, which allow us to create complex assemblies that combine copper with other materials. We also offer a range of surface treatments, including tin plating, nickel plating, and silver plating, to enhance corrosion resistance and solderability. By partnering with our precision engineering team, OEMs can move from prototype to mass production with the confidence that every component will meet their rigorous internal quality benchmarks and international safety standards.

Applications in Emerging Technologies

Precision copper components are the "hidden" drivers of the modern technological revolution. In the automotive sector, they are used in EV battery thermal management systems, high-voltage connectors, and radiator assemblies. In the renewable energy industry, custom copper busbars and connectors are vital for solar inverters and wind turbine generators. The telecommunications industry utilizes our precision-machined copper parts for 5G base station cooling and RF shielding. In the medical sector, we produce specialized components for MRI machines and cryogenic cooling equipment used in labs. Additionally, we manufacture custom induction heating coils for industrial metalworking and high-precision fluid nozzles for chemical processing. The versatility of our fabrication capabilities means we can support applications ranging from sub-miniature electronic contacts to large-scale industrial heat dissipation assemblies.

Advantages of Custom Precision Engineering

The primary advantage of our precision components is "Optimized Performance." By customizing the shape, alloy, and temper of the copper, we help engineers reduce the weight and size of their products while increasing their thermal or electrical efficiency. Another advantage is "Assembly Integration." We can manufacture complex sub-assemblies that are ready for immediate installation, reducing our clients' in-house labor costs and supply chain complexity. Our advanced plating services provide the advantage of "Environmental Resilience," allowing copper to be used in corrosive or high-humidity environments where bare copper might fail. For high-volume OEMs, our "Design for Manufacturability" (DFM) support helps identify cost-saving opportunities during the prototyping phase. Finally, our 100% inspection policy ensures that every part delivered is defect-free, which is essential for industries where a single component failure can result in an expensive product recall or system downtime.

Logistics, Prototyping, and Quality Assurance

We support the entire product lifecycle, from initial prototyping to high-volume production. For the development phase, we offer "Rapid Tooling" services to provide samples within 7-14 days. Once approved, we scale to mass production with automated quality monitoring. Payment for custom components often involves a tooling deposit followed by T/T terms for the production parts. Packaging is customized for each part to prevent damage; we use custom foam inserts, ESD-safe trays for electronic parts, and vacuum-sealed bags to prevent oxidation during transit. We ship globally via air-freight for urgent components or sea-freight for bulk orders. Each batch is accompanied by a full Quality Inspection Report (QIR), including CMM dimensional checks and material certificates, ensuring full traceability and compliance with your internal quality management system.

  • Q: What file formats do you accept for custom designs?
  • A: We accept all major 3D CAD formats, including STEP, IGES, and SolidWorks, as well as 2D PDF blueprints with tolerance specifications.
  • Q: Can you provide tin-plated copper busbars?
  • A: Yes, we offer in-house tin plating which is the standard for improving the corrosion resistance and electrical contact quality of copper busbars in power distribution.
  • Q: Do you offer assembly services (e.g., copper with plastic or rubber)?
  • A: Yes, we can provide over-molding and multi-material assembly services to deliver a finished sub-component to your production line.
