Friction stir welding (FSW): The equipment is highly automated and mechanized, suitable for large-scale production, and has low requirements for the operating environment. It has broad application prospects in fields such as aerospace, automotive manufacturing, and shipbuilding.

It introduced the R&D capabilities of the CNAS laboratory.

Aluminization Scheme for Three Electric Products

Introduction to Three Electric Systems

The three electric systems refer to the power battery, drive motor, and electronic control system, which are the core components of NEVs and determine the vehicle's performance, driving range, and reliability.

Battery System - Battery Pack Assembly Products

Product Introduction: The battery tray product is used for passenger NEVs, serving as a carrier for modules or battery cells and providing safety protection. Its main body is assembled by welding profiles and is supplied in an assembled state.

Product Advantages: The side beams and bottom plate adopt a multi-cavity cross-section, offering excellent resistance to extrusion, stone impact, and dropping. Advanced joining processes such as friction stir welding and laser welding are employed, resulting in minimal product deformation, high connection strength, and excellent sealing performance, fully meeting the sealing requirements of battery tray products. A complete set of tooling for battery tray products has been developed, significantly improving production efficiency.

Battery System - Side Beam Products for Battery Packs

Battery System - Bottom Plate Products for Battery Packs

Product Introduction: Ultra-wide integrated extruded multi-cavity water-cooled plates leverage the company's advantage in large-section extrusion to increase the width of the bottom plate, reduce the number of friction stir welds, and achieve cost reduction. Using 6005A or 6061 alloy, the width can exceed 500mm.

Lightweight Aluminum Alloy Solutions: Utilizing ultra-wide thin-walled sections with integrated forming; reducing the number of friction stir welds for high product strength; sample supply has been completed, with satisfactory customer feedback.

It also elaborated on products such as side plates and end plates for battery modules, motor housing products for the drive motor system, and busbar products for the electronic control system within the battery system.

In addition, it introduced the company profile, qualifications, and scientific and technological achievements of Liaoyang Xiangyu Aluminum.
