Our Shot Blasting facilities are a new addition to the portfolio of services we operate from our plant in the Port of Mostyn.
Removal of oil, dirt, lubrication greases, metal oxides, welding scale etc. is essential prior to the powder coating process as this can cause problems like uneven coating or problematic chemicals mixing in with the powder coat paint.
This blasting method of preparing the surface prior to coating is known as abrasive blasting or shot blasting. Blast media and blasting abrasives are used to provide surface texturing and preparation, etching, finishing, and degreasing. Shot blasting is a method used to clean, strengthen (peen) or polish metal and is typically done in a blast room. The blast area is a three part system; the containment structure, the abrasive blasting system and the dust collector. Most blast rooms will have a recycling system of some description. This can range from manually reclaiming the abrasive blast using a shovel to reclaiming floor systems that convey the abrasive into a cleaning device before ending back up in the blast pot.
Shot blasting will ensure that the steel is cleaned to bare white metal, SA2.5 / SA3, giving the best possible surface essential for the application of paint to the finished fabrication item.
