We offer a number of post-processing and surface finishing services both for CNC machined parts and sheet metal. Post-processing improves characteristics of the parts: their surface roughness, general durability, corrosion resistance or their appearance.

Coating services

Galvanic Zink

Purpose: Zink coating (galvanization) protects parts from rusting.

Materials: This method is suitable for steel and iron.

Nickel & Chrome

Purpose: Nickel and chrome coatings (plating) are often used for decoration, anti-corrosion purposes or to increase surface hardness.

Materials: these methods are suitable for parts out of all metals.

Anodising: hard & colour

Purpose: Anodising protects parts from corrosion, provides their durability and makes parts non-conductive. Parts can be dyed upon anodising.

Materials: anodising is suitable only for aluminium and titanium.

Surface finish


Purpose: polishing is used to remove marks left from CNC-machining, contamination and oxidation and improve appearance of the parts.

Materials: applicable for all materials.


Purpose: bead blasting is used mainly for improving appearance characteristics of ready parts.

Materials: applicable for all materials.

Painting & Powder coating

Purpose: powder coating is used to increase smoothness of surfaces and make parts resistant to corrosion. Powder coating can be also used for colouring purposes.

Materials: applicable for all materials.

Heat treatment

Quenching and tempering

Purpose: quenching is used to increase surface hardness of parts. Tempering reduces brittleness of the quenched parts.

Materials: this method is suitable mainly for steel and steel alloys.

Normalizing and tempering

Purpose: normalization or annealing process eliminates stresses from CNC machined parts, which stabilizes mechanical properties of the parts, while tempering reduces brittleness of the quenched parts.

Materials: stress relieving is suitable for all alloys. Tempering is suitable for only steel alloys.
