All our finishing options:

To meet your needs, we offer a wide range of finishes and treatments for each of your prototypes or low-volume production. We can guarantee functional (e.g. roughness) or aesthetic (e.g. sandblasting) surface conditions as well as heat and mechanical treatments.

The objective is to meet your expectations as best as possible, and to deliver parts that comply with the constraints of your specifications.

  • Paints
  • Chrome plating
  • Sandblasting
  • Polishing
  • Brushing

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 otherwise specified .

Chrome plating

Chrome plating can be decorative (to give the part an aesthetic 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 aesthetic 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.
