Premium Water-Cooled Motor Housing+ Friction Welding

Premium Water-Cooled Motor Housing | Aluminum Profile + Friction Welding

Product Overview

This water-cooled motor housing is specifically engineered for high-power-density electric motors. We move beyond traditional casting methods, starting with premium aluminum extrusions. Through precision CNC machining of internal water jackets and critical interfaces, and then integrating the end caps with the main body using Friction Welding, we create a housing that guarantees absolute coolant sealing while offering superior structural integrity and thermal performance. It is the ideal choice for new energy vehicles, industrial servo motors, and high-end machinery applications.

【Core Technology: Friction Welding】

Traditional welding or casting methods often risk porosity, cracks, or leaks. Our Friction Welding process is a solid-state joining method that offers distinct advantages:

100% Leak-Proof Sealing: The thermoplastic bond creates a weld strength nearly matching the base material, completely eliminating leak risks in the water cooling circuit.
Filler-Free Joining: No welding wire or flux is required, which prevents galvanic corrosion from dissimilar metals and ensures the cleanliness of the water channels.
Eco-Friendly & Precise: The process generates no smoke or spatter. The heat-affected zone is minimal, preserving the dimensional accuracy achieved in prior machining steps.

【Material & Workflow】

Base Material: High thermal conductivity aluminum alloy (6063/6061 Extruded Profile).
Pre-Machining: Aluminum profile extrusion forms the basic structure and initial water jacket shape.
Precision Machining: 4-axis/5-axis CNC machining ensures precise fit and critical dimensions.
Joining: End plates are fused to the main cylinder via Friction Welding.
Finishing: Stress relief, 100% pressure leak testing, and surface finishing (anodizing/painting).
