Plastic Decorative Coating

Attractive designs with intense brightness are the demanding trend for automobile lamps. The design method is to apply a very bright metal aluminum layer on the surface of the lightweight plastic to form a mirror like finish on the surface. The mirror reflection effect of the parabolic curved back surface is matched with the front transparent lamp shell pattern, and concentrating the light source focal length of the paraboloid to form a parallel beam, sculptured light source.

The market demand for automobile lamps has been changing from the traditional halogen lamp to the LED lampDue to the intensity and precise focal point requirements of the LED lamp to produce the desired appearance, improved mirror finish coating are required. DAHYOUNG has accumulated process technology through research and development to meet these requirement so the LED lamps can be perfectly displayed as desired.



  • Headlights
  • Tail lights
  • Fog lights
  • LED lights(High Depth / Width Ratio)


  • Primer/reflective/face coating process in a vacuum chamber for low contamination and rapid production
  • Good film thickness uniformity and stable quality
  • Topcoat with high transparency, good reflectance of the lamp after coating
  • Can be plated with high aspect ratio headlights, eg LED, OLED, laser
  • Special process design can effectively solve the abnormality of bluish blue, white fog, lighting or high temperature baking test
