GLASS BEAD BLASTING / WHITE CHROMATING

2004

Dear sir,

I have a 6063 aluminium strip of T6 temper. This is for the front fascia of an amplifier. The letters have been done by CNC and the space inside has to look white in colour.

I tried getting the space blasted with sand, but got a very rough finish and the colour was grey. Then tried the same thing again with aluminium oxide blasting and this time the colour was light grey and the surface smooth.

I have heard that I can get the white finish by glass bead blasting or by a process of white chromating. Do you know if this will work or if anyone can do this in India.

The chromating is not a transparent or clear type. I will be grateful if you can do the needful.

Thank you Regards,

As an alternate try to use an epoxy paint which has titanium dioxide [on eBay or Amazon] used as filler, and cure. As the letters are with depressions (I hope) this may give result.

Good Luck

We can do the glass bead blasting and chromating for you, provided you mask the area you don't want blasted.
