1. Applications in the New Energy Sector
CNC precision machining plays a central role in producing components such as:
- Battery housings and enclosures – lightweight aluminum and stainless steel shells ensuring safety and heat resistance
- Cooling plates and heat sinks – intricate channels for efficient thermal management in EV batteries and electronics
- Motor housings and transmission parts – high-strength alloys with tight tolerances for performance and efficiency
- Wind turbine structural parts – precision hubs, shafts, and fasteners capable of withstanding extreme stresses
- Solar mounting brackets – corrosion-resistant aluminum parts for long-term durability in outdoor environments
2. Material Expertise
New energy components often require specialized materials for performance and sustainability:
- Aluminum alloys (6061, 7075, 6082) – lightweight and corrosion resistant
- Stainless steels (304, 316, 17-4PH) – strength and corrosion resistance in harsh environments
- Copper and brass – high conductivity for battery terminals and busbars
- Engineering plastics (PEEK, PPS, PA66) – electrical insulation and thermal stability
We have extensive experience in machining both metals and polymers, ensuring each component meets its functional demands.
3. Precision and Functional Integrity
In new energy systems, micron-level precision directly impacts performance:
- ±0.005 mm tolerances for battery cooling channels
- Perfect sealing surfaces to prevent fluid leakage in cooling plates
- High concentricity and balance in rotating wind and motor components
