Tomburn specialise in the pre-treatment of aluminium, mild and galvanised steel, zintec and both ferrous and non-ferrous castings.
It is imperative in the finishing industry to have clean substrate which is free from contaminants before the finish is applied, as failure to correctly prepare the substrate will ultimately result in the failure of the coating in the field.
Tomburn have both Chromate Conversion and Zinc Phosphate chemical pre-treatment facilities:-
Chromate Conversion is a proven system which ensures an excellent adhesion between the finishing layer and the aluminium and is specified by all major powder manufacturers offering external warranties.
Zinc Phosphate offers a superior pre-treatment to iron phosphate, which provides a good adhesion between the finishing layer and the ferrous material.
Tomburn have shot blasting facilities for steel to SA 2.5 and sand blasting facilities for aluminium substrates.
We have both automatic and manual blasting facilities which are able to handle a variety of shapes and sizes for new products and restoration projects.
