Surface treatment

Enhance the visual appearance, technical functionality or durability of your casting.

Increase your product lifetime with surface treatments

Casting related processes like tumbling (with ceramic stones) or shot blasting (with different media) are the standard processes of our foundries. This gives smooth surfaces to continue towards the final surface.

What is more, we help you to increase the cast corrosion resistance with passivation (Surtec 650 and E-Clps). The good base against corrosion starts with the right aluminium alloy selection.

In consequence, together with the right alloy and passivation, your product lifetime will increase significantly. We do these processes in-house and with the help of our local partners.

Wet / Powder / CED Painting

Painting, either wet or powder painting will finalize the smooth and visual surface for your cast product. Powder coating is widely used for cast components as it’s an easy and fast way to get product image different.

We help you to find suitable paint based on your product use (internal/external use). We do painting in-house and with our local dedicated partners.

Furthermore, we serve you with CED (Cathodic Electro Deposition) painting with the help of our partners. Anodization belongs to our surface treatment offer portfolio as well. By anodization, you will get cast surface durability improved against mechanical wear.


The product with strict needs of the radio frequency signal (electrical performance) will be plated with various metal (Ni, Cu, Ag) on top of cast product in electro metallic plating.

The process control is done with visual checks, x-ray control and q-value measurement with network analyzer at factories.

We offer metallic plating and related test and guidance with our partners and also in-house in India.
