From EV motor spindles and battery cooling plates to liquid cooling connectors and sensor brackets, LC Manufacturing delivers high-strength, precision-machined components that keep new energy vehicles and energy storage systems running safely and efficiently.
Advantages of CNC Machining for New Energy Vehicles
The electrification of vehicles demands components that combine high strength, thermal performance and long-term reliability under demanding operating conditions.
High-Strength Materials
45# steel, aluminum 6061/7075 and stainless steel parts engineered for motor housings, connectors and structural components.
Heat treatment options such as quenching to HRC 50-55 for wear-critical parts.
Thermal Management
Liquid cooling connectors and cold plates with flow-channel roughness Ra 0.8um and leak rates below 0.01mL/min.
Improves cooling efficiency by up to 20%, protecting batteries and power electronics.
Lightweight Design
Aluminum 7075 and thin-wall structures reduce weight by up to 30% for extended range.
Five-axis CNC handles complex lightweight geometries without sacrificing strength.
Precision & Consistency
+-0.005mm tolerances with high concentricity for rotating and sealing components.
Batch-to-batch consistency supported by standardized parameters and 100% inspection.
