Paints - Powders & Epoxies

Finish applied by spraying powder or epoxy paint in a large choice of colors:

  • From a RAL or PANTONE reference, or a sample
  • All kinds of finishing: Satin, matte, glossy, soft touch, textured and chrome-style painting

The default finish will be matte, unless specified otherwise.

Chrome plating

Chrome plating can be decorative (to give the part an esthetic finish) or functional:

  • Chrome bath (glossy, matte or satin appearance)
  • Chrome bath with electrical conductivity


High-pressure blasting to eliminate machining marks and/or allow the desired esthetic appearance to be added to the part depending on the size of the grain.

  • Close to a VDI 3400 (Charmilles)


Performed using different methods to obtain a high-quality surface finish:

  • Smooth and shiny appearance
  • Transparent for PMMA and PC parts
  • Manual polishing or steam polishing for details on optical parts


Brushing can be circular, diagonal or longitudinal to give your part the required effect.

It can be performed using a sample to ensure we get as close as possible to the desired result.

Laser etching / engraving

Laser etching involves removing the first layer of a finish to reveal a chosen pattern or logo, which stands out due to the difference in color between the two layers.

Laser engraving involves removing a greater depth of material in a desired shape (serial number, logo, etc.). It is therefore permanent and highly resistant to abrasion.

Printing - Pad printing - Silk printing

These finishing allow you to identify, number and/or customize your parts.

  • Colors according to a Pantone or RAL reference
