From high volume production vehicles to leading edge technology Formula 1 cars, the automotive industry has a need for a wide range of laser applications related to the manufacture of vehicles and automotive components.
For traceability and tamper-proof identification of individual components or complete vehicles, there are hundreds of laser marked items in every car. Since virtually any material can be laser marked there is normally a solution to suit every requirement. Some of the most established applications are:
- VIN plates and identification labels including “boiler plate” details
- Stencil cutting for vehicle glass security code etching
- Permanent 2D matrix marking of motorsport components
- Backlit display marking (Day & Night) for instruments & switches
- Gearbox component marking with part numbers etc.
High power lasers with fibre optic beam delivery lend themselves to integration with robots for cutting of 3D automotive components, addition of optional holes and location features. Plastic components can be degated, trimmed or have option holes cut in them according to the requirements of the vehicle. Our metal cutting lasers can be used to provide fine and accurate cutting, with low heat input – even on painted metal surfaces. We can advise you on the best laser for your specific application and arrange to process sample material for your evaluation.
Whether polymers or metals, there are many applications for laser welding in the automotive market.
Our remote welding system uses a scanning head to achieve the ultimate throughput and reduce the move time between welds to the absolute minimum – in the example video below you can see a high power CO2 laser performing 270 welds in 130 seconds.
Our solid state lasers are used for welding of a large variety of materials in the automotive sector including:
- Engine and exhaust components
- Vehicle safety systems
- Electronic sensors
- Structural sheet metal parts
Rofin also produces dedicated system solutions to seam weld tubes and profiles, including high speed seam tracking to ensure that quality is not compromised by the non-linearity of the joint interface or variable gaps.
Fine welding of automotive electronic assemblies can be used to provide strong welds with low electrical resistance or to hermetically seal packages against the extreme environments experienced in modern vehicles.
Plastic packages are sealed by laser welding to achieve a completed assembly where the laser weld is stronger than the wall of the component. Our range of diode lasers are efficient and require no routine maintenance, they can be delivered with scanning optics to track complex contours at high speed.
