Sand Blasting

Sand blasting is primarily a pre-treatment process. It is usually carried out to ensure that the surface of a part is thoroughly cleaned before PTFE coating or the other conversion processes.

Blast cleaning is done in a suction blast machine using mainly aluminium oxide. Other blast medium can be used also.

A major advantage of this cleaning process for ferrous substrates is that not only are old paint films removed, but also rust and scale, leaving a clean metal surface which is ideal for re-coating.
