Individualization & functional enhancement in automotive industry (40.000 individualized vehicles per day at VW)
Variant diversity with decreasing batch sizes
Differentiation and increased efficiency of production by means of printing and laser processes using the example of printed conductor lines/cable harnesses, sensors and control elements of a car door
In a car door, operating elements were integrated as printed switches and lighting, and an electric motor was electrically contacted on aluminum and plastic surfaces. Thereby, robot-guided dispensing or inkjet printing processes are used. A new process is also used to apply copper wire lines together with an insulating sheath directly to the component. This saves the standard installation of a cable harness segment.
■ Printing of electrodes and piezo-active layers for pressure-sensitive button applications and LED lighting
■ Digital production of through holes (vias) by laser
■ Digital production of connection interfaces
■ Lighting simulation for individualized button layouts
■ Application of piezo elements on aluminium sheets
■ Optimization of resonance frequency and sound pressure level by laser ablation of the metallic substrate
■ Maximum sound pressure level at 38,9 kHz applicable as ultrasonic proximity switch
■ Robot-controlled printing technology for the production of conductive tracks on 3D objects
■ Closed CAD-CAM chain for fast exchange of print layouts on 3D objects
