This direct surface coating process combines injection molding and painting into a single process step without the need for post-mold processing. Directly in the injection mold, a thermoplastic carrier tape is flooded with a polyurea or polyurethane paint system. WEIDPLAS, the experienced multi-component injection molding specialist, has applied this technology and taken it even further. The application of this technology for series production is now ready for global introduction.

Why ColorFuse?

Compared to conventional painting, ColorFuse offers:

  • An integrated technology into existing manufacturing process, with no investment in complex painting lines and further minimizes logistics costs

  • High-gloss, scratch resistant surfaces in direct connection to unpainted areas without masking

  • Completely new design possibilities with elegant high-gloss optics for components with high aesthetic standards including logo depiction

  • Quick production with a wide range of variations

  • Transparent paints or metallic paints feasible

  • Production of multi-colored coated components in one process step without masking

What is the advantage compared to other process or materials?

Several colors, varying surface textures, clear coat surfaces  with depth effects, partial textures, designer lines, lettering and much more. And the time needed to change colors is much shorter compared to conventional processes. The paint is also resistant against climatic and environmental effects such as UV radiation.

WEIDPLAS Design and Engineering Expertise

The flow-coating process in the tool cavity imposes some geometric constraints on the design and development of the component. This is where the our Product Management and TVC (Testing & Validation Center) can offer an ideal platform for pre-trials or development projects.

Environmental Sustainability

This aspect is important to us. Firstly, the applied reactive paint is solvent-free. And painting in the injection molding tool will produce no over-spray with its excess consumption and laborious disposal. Energy consumption is also clearly reduced compared to conventional painting facilities.


WEIDPLAS is considered the system integrator in term of with this technology. After several preliminary development projects with our partners, we are continuously working on the further developing this technology and on integrating more functions into ColorFuse components.
