ColorForm technology

PUR coating in injection molding (in-mold coating)

Product information

With ColorForm technology, you can coat plastic components directly in the injection mold - efficiently, cost-effectively, and without the need for an additional painting system. This innovative process combines multi-component injection molding with in-mold coating (IMC) and enables high-quality, scratch-resistant surfaces in a single process step.
 
 
What is ColorForm?
 
 
ColorForm is a process for PUR coating in injection molding, in which thermoplastic components are finished with a polyurethane (PUR) surface immediately after injection molding.
Unlike traditional plastic painting, the coating is applied directly in the mold (“inline”). The key advantage: plastic parts can be painted directly in the injection mold—a separate painting system is no longer necessary.
 
As a result, ColorForm completely replaces the traditional painting process and offers an efficient alternative to conventional plastic painting.
 
 
Companies benefit from numerous advantages:
  • Significant reduction in production costs by eliminating additional coating steps
  • Minimization of logistics costs and internal transport distances
  • Lower scrap rates compared to traditional coating processes
  • Space-saving and efficient production concept
  • Cost-effective production of premium surfaces with innovative design effects
  • More sustainable production through reduced material and energy consumption

Perfect color. Perfect surface. Perfect functionality. All in one step.

The ColorForm process (in-mold coating in injection molding) combines multi-component injection molding with in-mold coating, enabling the efficient production of high-quality plastic surfaces.
 
 
An overview of the individual steps of the ColorForm process:
  • Placing the film onto a handling frame for precise positioning in the subsequent manufacturing process
  • Repositioning the film handling frame within the production cell
  • Applying the polycarbonate design film as a decorative and functional surface layer
  • Inserting the design film into the cavity of the thermoforming mold
  • Injection molding of the third component (PC-ABS) to bond the carrier structure and the surface
  • Removal of the finished component, including the film handling frame
  • Storing and returning the film handling frame to the production cycle
  • Storing the finished plastic part with a high-quality, coated surface

The ColorForm cycle. Painting directly in the mold.

ColorForm parts

High gloss, depth effect, and texture in a single surface.

 
 
 
ColorForm technology enables the production of high-quality plastic surfaces via injection molding that combine multiple visual and functional effects: high gloss, depth effect, and precise surface textures. The use of in-mold coating with polyurethane (PUR) results in durable and visually appealing components - without the need for subsequent painting.
 
 
 
Companies benefit from significant efficiency and quality advantages:
  • Up to 40% cost savings by eliminating painting processes
  • Reduced CO₂ emissions due to lower energy and material consumption
  • No solvents or paint waste ensures more sustainable production
  • High-gloss, scratch-resistant surfaces without orange peel
  • Lower scrap rate due to stable processes
  • Space-saving production concept without a separate painting system
  • Custom surface textures through microstructured tool surfaces

Colorform components

What makes surfaces produced with ColorForm stand out?

  • High-gloss surface without an “orange peel” effect
  • Precise parting lines due to mold design – no color separation
  • Surface effects created by a microstructured mold surface
  • Detailed microstructures: grain patterns, design textures, and lettering
  • High scratch resistance thanks to a self-healing surface
  • Transparent coating systems create depth effects
