Industry Pain Points


  • High defect rates (leakage, porosity) in large-size aluminum battery trays.

  • Long outsourcing chains increase delivery risks and costs.

  • Inconsistent welding depth control leads to rework and scrap.

    These issues are common in aluminum battery tray welding, especially for large-format EV battery trays.

Why Choose Our Service

  • Flexible Processing Modes: Welding-only (customer-supplied parts) or one-stop turnkey manufacturing.

  • Thickness Optimization: Covers the common 3–10mm range for EV battery trays.

  • Defect-Free FSW Process: Stable torque & precision clamping ensure leak-proof results.

  • Faster Delivery: Reduce supply chain steps with integrated production.

  • EV Expertise: Proven track record with top EV battery pack suppliers.

Applications

  • EV Battery Pack Cooling Trays

  • Aluminum EV Battery Trays (FSW Process)

  • Large-Format EV Battery Base Plates

Technical Highlights

  • Welding Depth Capacity: Optimized for 3–10mm aluminum alloys.

  • Fixture Flexibility: Custom fixturing for large rectangular structures.

  • Automation Ready: Scalable to robotic integration for mass production.

  • Data-Driven QC: Real-time monitoring & process traceability.

  • Process Technology: Friction Stir Welding (FSW) for aluminum battery tray structures

FAQ

Q1: Do you support different EV battery tray designs?

A1: Yes. We process both customer-supplied trays and fully customized battery tray designs, ensuring compatibility with various EV platforms.

Q2: Why is friction stir welding suitable for EV battery trays?
A2: Friction stir welding provides solid-state joining with low heat input, making it ideal for aluminum EV battery trays that require high strength, airtightness, and minimal distortion.

Q3: What size and thickness can you weld?

A3: We specialize in large-scale trays up to several meters long with weld depths suited for structural stiffness and load-bearing capacity.

Q4: Can you handle mass production?

A4: Absolutely. Our automated FSW lines are designed for high-volume manufacturing, reducing cycle time and ensuring consistent output.

Q5: What makes your service different from other suppliers?

A5: Unlike traditional welding shops, we focus on lightweight aluminum battery trays, offering design support + scalable production tailored for the EV industry.
