Finishing
Make it unique
In order to truly assess a product's aesthetics in the early stages of product development, it is absolutely worthwhile to build a prototype with a high-quality finish. Using various finishing techniques, we can match or surpass the quality standards of the final product.
Surface treatment and Decoration
We offer endless finishing possibilities including:
- Painting, silkscreen and pad printing
- E-coating (KTL), powder coating and anodizing
- Galvanic chrome plating
- Metallization and PVD-coating
- Flocking
- Finishing with leather, films or textiles
- And many more...
Assembly
Ready to install
Besides the production of separate parts, we can also take care of the assembly of an integrated module or even a full product. We are especially skilled in:
- Complex assemblies with multiple options, e.g. bumper facias and door panels
- Functional lighting modules including PCB’s
Welding
- Vibration Welding (friction welding)
- Hot plate welding (mirror welding)
- Ultrasonic welding
Industrial Gluing
- For all types and combinations of plastics, including surface preparation
- Metal and plastic bondings
- Adhesive tapes and kit
