Without perfect pre-treatment or shot blasting, powder coating never stays for sufficient time and the entire expenses is wasted. As we are specialized powder coaters in Poole, Bournemouth, Dorset we are very particular about this pre-treatment process.
Proper shot blasting would ensure removal of rust, previous paint coatings, and mill scale to make the metal surface completely bare. Powder coating on any surface other than bare metal is never durable. By technical standards, metallic surface ratings have been fixed at SA 3 and SA 2.5 to be judged fit for powder coating.
Ways of Shot Blasting
Shot blasting essentially involves firing of minute particles under total control. This helps erode or etch away surface contamination that exists in the form of solids. Our expertise lies in the use of proper abrasives in terms of size, shape and metallic nature of a particular item. Shot blasting could be carried out in large dedicated rooms or even in specially built cabinets. Our blast room measures about 10 feet x 8 feet.Both manually operated and automated shot blasters are used for pre- treatment of metallic items
This is a closed loop arrangement wherein an abrasive could be recycled after being used. Blast cabinet is an assembly of four separate functions, a cabinet, blasting system, abrasive particle recycling process and waste particle collection. The cabinet uses both dry and wet processes of blasting the dry process based on suction and the wet system based on injecting liquid abrasives. Wet process of blasting is used when there is possibility of damage to a metallic surface from the heat generated from friction in dry procedure.
The blast room could be considered a giant adaptation of a blast cabinet. A blast room contains all but the recycling facility of a blast cabinet. Recycling for a room is done manually with shovels and sweeps.
Abrasive Components Used in Blasting
Abrasives are a vital ingredient of shot blasting. Silica in form of sand is the commonest of the abrasives used in blasting. However silica being prone to conversion to dust results in health hazards for blast room operators. Commercial varieties of silica used for blasting is often coated with resins to control dust emission. Garnet is a more expensive though safer abrasive as it produces dust in limited quantities.
Steel shot, Aluminium Oxide, Sand, Walnut Shells and Glass Bead are also used as abrasives in blasting.
