In the automotive industry, laser cutting technology is an integral part of metal production. We use laser cutting with millimetre precision (positioning tolerance of ±0.1 mm) to produce high-strength steel sheets, aluminium alloys, engineering plastics and other materials for precision automotive parts. Our fully digitised production system offers functional innovations that go beyond traditional processes, from new explosion-proof batteries to lightweight suspension systems for racing cars, to the OEM and tuning market.
DP980 1.2 mm double-steel DP980 steel is precision-cut by a 3,000 W fibre laser with a controlled thermal zone of 0.3 mm. This maintains an initial tensile property of above 980 MPa and controls the deformation of the cushion assembly in the event of a collision. The deformation of the bumper cushion assembly is controlled in the event of a collision. The new energy battery uses 2.0 mm thick 6061 aluminium alloy with tiny laser-cut holes that improve thermal efficiency by 40% and eliminate the risk of short-circuiting. Underwater laser-cut carbon fibre composites are used for the bases of racing car engine compartments, offering a thermal resistance temperature of 1200°C and a 50% weight reduction. The synergy between material and process enables the same substrate to be used to cut 0.5 mm thin profiles for ECU shields and 8 mm bevelled edges for differential gear bases. This opens up new possibilities for reducing vehicle weight and achieving functional integration.
The value of custom automotive components lies in turning design concepts into ready-to-use industrial products:
Prototyping phase: 24-hour parts service to support design iterations
Enabling mass production processes: intelligent design systems facilitate the production of various materials, such as 304 stainless steel exhaust plates and spring steel clutch plates, with a production capacity of more than 5,000 units per day.
Laser engraving technology adds a friction coefficient code and VIN label to brake discs.
Revolution in aftermarket manufacturing: 3D scanning of old parts to create reverse engineering models and custom repair parts to achieve OEM-level compatibility.
The laser cutting process redefines the functional limits of key components:
Electrification conversion: pole terminals in battery modules are precision laser cut from composite copper and aluminium sheets, reducing contact resistance by 35%. The silicon steel plates in the motors are cut with a hole smaller than 0.02 mm, reducing iron loss by 15%.
Safety solutions: airbag brackets treated with microporous femtosecond lasers (ø 0.4 mm aperture), reducing response time to 0.01 s; laser cut depth error ≤ 0.1 mm in the induction grooves for energy absorption in the shock beam, ensuring precise transmission of the shock force.
Exhaust manifolds: Titanium alloy exhaust manifolds have laser-cut flange surfaces (flatness ± 0.05 mm) to improve sealing. Carbon fibre intake manifold with laser-cut holes to optimise airflow and increase power by 8%.
Intelligent angular column drive: The millimetre radar columns are manufactured by laser cutting and casting, and the precision of the mounting holes ensures an angular beam alignment error of less than 0.3°.
