Alodine

Vertical type, bench drill, radial drilling machine can be used for drilling in metals and alloys such as aluminum, steel, copper, and polymers.

Bead Blasting

Depowdering of parts with bead blasting. The final parts are slightly grainy in the touch with a satin-like matte appearance.

Brushing

The brushing process helps to protect the surface of the workpiece, extend its lifespan, and improve its overall appearance.

Black Oxide

A process that forms an oxide layer on metal surfaces through chemical treatment to enhance corrosion resistance and reduce light reflection.

Chromate
