Body‑In‑White & Body Panels Industry Laser Solution

Industry Background

Automotive body‑in‑white panels include door inner‑outer plates, fender blanks, roof panels and various body reinforcement plates. Main raw materials are galvanized steel and high‑strength low‑alloy steel. In new‑vehicle R&D phase, large quantities of prototype sheet blanks are required for crash and assembly verification. Traditional stamping requires huge mould investment and long manufacturing cycle. Burr, coating damage and dimensional deviation will directly affect subsequent body‑in‑white welding assembly quality. Fiber laser realizes mould‑free flexible blanking, protects galvanized layer quality, adapts automotive prototype trial‑production and low‑medium volume variant production.

Sub Application Scenarios

• ✅ Door Inner & Outer Panel: Prototype blanking, contour trimming and mounting hole cutting
• ✅ Fender & Roof Panel: Body outer cover sheet prototype and variant parts processing
• ✅ Body Reinforcement Plate: Various local strengthening sheet for BIW structure
• ✅ Mock‑up Test Parts: R&D prototype sheet for vehicle assembly & crash simulation test
• ✅ Auxiliary Process: Laser welding for body‑in‑white assembly, pre‑weld surface cleaning

Industry Pain Points

• Traditional stamping needs expensive custom mould investment for automotive body panel parts.
• New vehicle R&D prototype parts face long lead‑time if rely on stamping die opening.
• Galvanized sheet is easy to suffer coating peeling and damage under conventional mechanical processing.
• Minor body‑panel design revision requires high‑cost stamping‑mould re‑work.
• Burr and dimensional tolerance error bring bad influence for downstream body welding assembly.
• Small‑batch variant production cannot amortize high stamping‑mould cost.
