Industry Pain Points We Solve


EV manufacturers face three major challenges when welding medium-size aluminum parts:

❌ High Scrap Rates – Traditional welding causes porosity and thermal distortion in cooling plates and wheels.

❌ Inconsistent Accuracy – Maintaining tight tolerances on medium-size EV trays is difficult with conventional methods.

❌ Slow Delivery Cycles – Long setup times and rework delays reduce production efficiency.

The FSW-BL2520 directly addresses these issues with precision gantry mechanics, real-time monitoring, and optimized spindle torque — delivering defect-free welds, stable accuracy, and faster turnaround.

Product Overview

The FSW-BL2520 is a medium-size gantry-style FSW machine, purpose-built for EV manufacturers requiring precision, rigidity, and stable throughput. Its optimized work envelope makes it ideal for battery cooling plates, aluminum trays, and wheel structures where accuracy and repeatability are mission-critical.

Applications

EV Battery Cooling Plates – Precision welding prevents leakage in liquid-cooled systems.

EV Battery Trays – Strong, stable welds for medium-size aluminum tray assemblies.

Aluminum Wheels – Robust structural integrity with minimal defects.

General Automotive Parts – Subframes, housings, and cast aluminum components.

Key Features

Precision Gantry Design – Ensures tight accuracy across medium workpieces.

High Rigidity Frame – Guarantees stable welding under heavy load.

Versatile Welding Range – Supports 3T/6T heads for ≤10mm and ≤20mm weld depths.

Intelligent Data Collection – Real-time process monitoring and quality control.

Reduced Scrap & Faster Delivery – Compared to TIG/MIG welding, lowers rejection rate and shortens lead times.
