As the automotive industry evolves toward lightweighting, electrification, and smart manufacturing, manufacturers are seeking more efficient and flexible production technologies to meet ever-increasing safety standards and manufacturing demands.
Key structural components—such as A-pillars, B-pillars, door ring reinforcements, sills, and battery trays for electric vehicles—are typically manufactured using ultra-high-strength steel, hot-formed steel, and aluminum alloys. While these materials enhance vehicle safety, they also increase the difficulty of processing. Complex curved surfaces, high-strength materials, and strict hole positioning requirements make traditional die stamping increasingly challenging. These processes often involve high tooling costs, long lead times, and limited production flexibility.
To address the manufacturing needs of automotive structural components and new energy vehicle parts, Han’s Laser offers end-to-end laser processing solutions covering coil laser cutting, 3D 5-axis laser cutting, automotive laser welding, and automated production line integration, helping global automakers improve production efficiency and achieve flexible and intelligent manufacturing.
Coil Laser Cutting Machines for Flexible Automotive Blanking
As the first step in automotive sheet metal processing, blanking directly impacts material utilization and production efficiency. Compared to traditional stamping, coil laser cutting eliminates the need for custom dies, significantly improves material utilization, and substantially shortens production line changeover times.
The Han’s Laser GRC series coil cutting production line integrates automatic uncoiling, high-precision leveling, and multi-head laser cutting, with an optional automated unloading system.
This series can process high-strength sheet metal with a yield strength of ≤980 MPa, achieving a leveling accuracy of 1.0 mm/m² and a cutting accuracy of up to 0.07 mm/m.
Key advantages include:
•Improved material utilization through optimized cutting layouts
•Reduced production setup time with no need to change dies
•Higher cutting quality with smooth edges and fewer burrs
This solution has been applied to the production of customized automotive blanks, including components such as doors and rear door panels for electric vehicles, effectively reducing tooling costs while improving production efficiency and product consistency.
3D Five-Axis Laser Cutting Machine
High-Precision Machining of Hot-Formed Automotive Structural Parts
With the widespread use of hot-formed steel in automotive safety structures, manufacturers have set higher standards for the precision machining of complex 3D components.
Automotive structural components formed through hot stamping typically feature complex curved surfaces, and some hot-formed steels can achieve strengths exceeding 1,500 MPa. Traditional machining equipment struggles to perform high-precision processes such as hole cutting and edge trimming.
Han’s Laser’s 3D 5-Axis Laser Cutting Machine for Hot-Formed Steel is specifically designed for machining high-strength automotive components. With its high speed, high dynamics, and high stability, it meets the demands of large-scale production for automotive hot-formed parts.
This equipment is widely used in:
•Automotive A-pillars, B-pillars, and door ring structural components
•Battery trays and battery housings for electric vehicles
•Other high-strength 3D structural components
With a maximum single-axis speed of 100 m/min, the equipment meets the strict cycle time requirements of automotive production lines while ensuring cutting precision and consistent quality during long-term operation.
Dual-Beam, Dual-Head 3D 5-Axis Laser Cutter
For automotive ccomponents with multiple holes and complex cutting requirements, production efficiency and consistency are critical. Han’s Laser’s dual-beam, dual-head 3D Five-axis laser cutting machine is specifically designed to enhance efficiency in high-volume production scenarios.
Featuring a gantry-style structure, a lightweight dual-beam movement design, and dual 3D cutting heads, this machine enables simultaneous processing and flexible multi-angle cutting, with n×360° rotation capability.
Key advantages include:
•Higher production efficiency: Dual laser heads operate simultaneously, significantly shortening the processing cycle for multi-hole components.
•Consistent cutting quality: An advanced CNC system enables independent control, ensuring high precision and consistent performance.
•Improved production economics: Increased output per unit of time helps automotive manufacturers reduce manufacturing costs and improve overall production line efficiency.
This solution is particularly well-suited for the mass production of complex thermoformed parts, such as multi-hole door rings, as these parts require both high productivity and dimensional accuracy.
Laser Welding Equipment
Welding is a critical process that determines the strength and sealing performance of a vehicle’s body structure. Han’s Laser offers a wide range of laser welding equipment to meet various welding scenarios and process requirements.
Remote Laser Welding for Automotive Structural Components
Han’s Laser’s remote welding technology can be widely applied to automotive structural components, including A/B pillars, side sills, roof structures, doors, and EV battery trays.
Compared to traditional resistance spot welding, remote laser welding offers higher efficiency and greater flexibility.
Key advantages include:
•Welding speeds up to five times faster than traditional resistance spot welding, significantly reducing production cycle times;
•Support for complex weld seam designs such as O-shaped, S-shaped, and C-shaped;
•Single-sided laser welding improves spatial accessibility and reduces welding distortion;
•Narrower flange widths help reduce material usage and achieve bodyweight reduction.
Laser Wobble Welding for Aluminum Alloy Car Doors
With the trend toward lightweighting in electric vehicles, aluminum alloy body components are being used more widely. However, the Laser welding process for aluminum alloys is prone to issues such as porosity, distortion, and insufficient weld stability.
Han’s Laser’s oscillating welding technology, tailored to the welding requirements of aluminum alloy car doors and structural components, can effectively address:
•Weld porosity issues
•Welding distortion
•Weld bead formation stability
This technology features high weld quality and strong process stability, meeting the mass production demands for electric vehicle components.
