| Résumé : |
Combining attractive optics with the effect of metal haptics gives plastics surfaces an upgrade. However, finely brushed structures often disappear when the parts are subsequently electroplated or damage their surface. This can be avoided by mold and laser structuring of the blank and its chromium layer. |
| Note de contenu : |
- electroplated plastics as decor elements
- Surface structures of refined components
- A new process for brushed structures
- Laser structuring enables optical effect
- Achievements and requirements
- Process potential
- Figure : A chromium plated surface with and without brushed, fine haptic structuring, built with the new decor process of BIA
- Fig. 1 : Various chrome surfaces in comparison : classic gloss chrome, modern matt chrome surface and "texture chrome", a special BIA development
- Fig. 2 : The new process gives the chrome layer both the look and the feel of a brushed surface. It creates a high-quality overall impression and enables a selective distinction to unstructured areas
- 3. Schematic layer composition of an in-mold structured plastic component. Up to 60% of the fine graining originally applied in the mold is leveled off by the layers. The main segment consists of the approx. 25µm thick copper layer and the subsequent nickel layer
4. Microscopic image (magnified 10000 times) of a cut through the layer compositionof a brushed surface subsequent to electroplating. All layers are uniformly intact and not damaged by subsequent laser treatment |
