The automotive headlamp is one of the most important design features of any car, with the bezel – the trim ring located between the reflectors and the housing of the headlamp – playing a prominent and highly visible role in its styling.
As a consequence, aesthetics and a perfect surface quality, in addition to the more practical requirements of high temperature resistance, ease of metallization, resistance to climatic effects and moisture, dimensional stability and processability, have become key features of this injection-molded part.
The Global Automotive headlamp bezel market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
DuPont – With DuPont’s “Design-Materials-Processing” solution, automotive headlamps, a significant opportunity to personalize vehicle styling, can now be manufactured at a lower cost.
For the development of the new-look headlamp bezels on the Audi A4, the first-tier supplier of exterior automotive lighting, Automotive Lighting of Reutlingen (Germany), turned to this DuPont solution.
When specifying the material for the bezels of the headlamps (both xenon and halogen) of the new-look Audi A4 and Audi TT, Automotive Lighting chose Crastin over a range of potentially competitive materials.
The DuPont material provides much higher temperature resistance compared to standard polycarbonate, involves significantly lower cost compared to high-heat resistant polycarbonate and offers much higher temperature resistance with less outgassing compared to competitive PBT materials.
DuPont technical specialists in Germany were on hand to define the optimum part design, tooling and machinery to meet all technical requirements, achieve the lowest possible part cost and maximize productivity.
Many manufacturers of headlamp bezels have turned to DuPont for a customized solution that combines the exceptional properties of DuPontTM Crastin® PBT with innovative manufacturing techniques, design, and development for results that are more stylish and cost-effective.
In the past, these manufacturers may have relied on high-heat resistant polycarbonate or standard PBT polyester. Automotive Lighting, which is a global leader in exterior automotive lighting and was established as a joint venture between Magneti Marelli and Robert Bosch GmbH, is one of these businesses.
