EV Motor Housing Friction Stir Welding Service

We provide specialized EV motor housing welding services using friction stir welding (FSW), ensuring precision, leak-proof performance, and long-term reliability. Customers can either supply their own castings for welding, or rely on our turnkey service covering design, machining, welding, and testing. With experience in handling aluminum housings up to 10mm thickness, we reduce defect rates and improve dimensional accuracy. Our one-stop solution shortens delivery cycles, while strict quality control guarantees consistent performance. As a trusted partner in the EV supply chain, we deliver both flexibility and technical excellence to meet diverse project needs.
