Industry Pain Points We Solve

Automotive manufacturers producing battery packs and structural components often face:


❌ Low throughput from single-station welders that limit daily output.

Frequent downtime from fixture changes when welding multiple parts.

❌ High labor dependency due to limited automation and monitoring.


The DM5020 addresses these pain points with its large-format table, multi-station design, and intelligent automation – reducing cycle time and maximizing throughput.

Product Overview

The FSW-DM5020 provides large-scale productivity without compromising on weld quality. Its multi-station configuration allows simultaneous setup of different EV components, drastically reducing idle time and improving OEE (Overall Equipment Effectiveness).

Applications

EV Battery Packs & Cooling Modules Batch welding of multiple trays or cooling plates.

Long Chassis Beams & Subframes – Stable welding of oversized aluminum structures.

Automotive Battery Trays (Multi-unit Production) – Parallel production to reduce cycle time.

Large Aluminum Castings & Panels – Suitable for heavy-duty, long-span aluminum parts.

Key Features

Multi-Station Layout – Supports multiple fixtures, reducing downtime.

Ultra-Large Work Envelope (5000 × 2000mm) – Perfect for long and wide aluminum parts.

High Productivity – Maximizes output for mass production lines.

High Rigidity Structure – Ensures consistency across large-scale welds.

Intelligent Monitoring & Data Collection – Real-time quality assurance.

Automation Ready – Seamlessly integrates with EV production systems.
