SURFACES
THE PERFECT FINISH FOR OUR PIECES
Depending on the process, drop-forged aluminium parts have a smooth and a homogenous surface with a multitude of possible technical and decorative uses:
CHEMICAL PICKLING
This process achieves a smooth, matte reflective surface and a silvery sheen. Chemical pickling improves the metal surface's adhesion for any subsequent coatings.
BLAST CLEANING
Stainless steel beads are used to produce an advantageous, environmentally friendly surface with a matte silk finish. Important: for components under dynamic stress, this process adds increased strength.
shot peening
This guarantees the targeted hardening of the component surface in areas with high dynamic stress.
BALL BURNISHING
This process achieves a surface with a silvery sheen which is also advantageous for parts under dynamic stress.
COMBINATION OF BRUSHING, POLISHING AND BURNISHING
This surface treatment is of most use where a highly decorative finish is required.
DECORATIVE ANODISING
This anodising oxidation treatment makes it possible to provide a decorative colour finish in all metallic or matte tones. The anodised layer provides surface and corrosion protection.
TECHNICAL ANODISING
This anodising oxidation process produces a finish which protects against corrosion and damage. It will even protect against wear and increase hardness if the treated layer measures >30μm.
CHROMATING
This finish is often used as the ground for top coatings and as temporary corrosion protection. The type of chromating used is often yellow chromating.
passivation
This process is very similar to chromating, however in passivation chromium-6 is not used.
POWDER COATING
This process provides decorative and durable surface protection. Coating thicknesses measure approx. 80μm.
PAINTING
Standard cathaforetic painting paints are used to provide a decorative surface finish. However this is only able to provide limited corrosion protection.
ZnS COATING
This surface treatment achieves a thin organic/inorganic corrosion protection coating.
