Generally, cookware is blast cleaned prior to Teflon coating. It removes oxide layer from the surface as well as it imparts surface roughness to facilitate proper adhesion of Teflon coating.
NATIONAL ENTERPRISES has developed a fully automatic multi satellite blast-cleaning machine for this purpose, wherein the operator places the job on satellite between two fixture plates. The fixture plate shall prevent the job from flying off from blasting station and only exposes the surfaces, which are to be blast cleaned. The indexing turntable carries it into blast chamber where satellite starts rotating the blast station. As job rotates blast guns blast clean the job. After completion of certain nos. of indexes [index counter is provided for this purpose] machine shall stop automatically for preset time and shall restart again. Only loading and unloading of the job is carried out by operator, rest all operations are automatic.
