Shot Blasting
Our 20-foot enclosed shot blast room represents a huge investment in 2019 and will revolutionise the speed at which we can shot blast and prime steel with a range of media.
Shot blasting removes burrs, scale or rust that may interfere with the part’s integrity, appearance or definition. For use in almost every industry including aerospace, defence, nuclear, automotive, construction and rail.
Precision Masking
Aerospace, defence, electronics and customised precision masking are areas for which we have long been renowned, with staff exceeding an average of 25 years’ experience in this department alone. We take immense pride in a beautiful job and the key to a successful finish is in the fine lines, sharp edges and meticulous detail.
Stove Enamelling, Painting and Powder Coating
Powder Coating
Powder coating is applied electrostatically as a freeflowing, dry powder and then cured under heat. The main difference between liquid paint and a powder coating is that the powder does not require a solvent and provides a tougher, more flexible finish.
Wet paint & Stove Enamelling
With over 40 years’ experience in the finishing industry, we have the expertise you need. We supply stove enamelling and paint applications to a number of MOD and aerospace specifications, as well as to the electronics industry. Our team is highly skilled and experienced in complex masking and paint finishes.
We can process to the below paint specifications.
