Powder Coating
Powder coating is an efficient, cost-effective method of applying coatings to metal components using a free-flowing dry powder in a wide range of colours and finishes.
Pre-treatment
Preparation of components is a vital operation to the success of creating a tough, hard finish, and is something we take seriously.
We have a 3-stage iron phosphate submersion pre-treatment process conforming to Def Stan 03-11 Class 1, which ensures a consistent repeatable de-greasing of all surfaces to achieve a quality finish and superior adhesion. The treatment also acts as a rust inhibitor.
Application
We statically charge the particles of powder, which are released through a corona gun to the grounded work piece to be coated. With the skill of our operators and the fine controls of our powder system, we are able to apply a repeatable uniform film thickness coupled with consistent gloss levels. We routinely undertake scratch-testing and gloss level checks.
Curing
Our continuous conveyor and gas-fired tunnel oven enables us to heat the components to 200°C (390°F), enabling the powder to melt and flow onto the structure of the part, creating a film coating on the surface.
We have incorporated a large box oven enabling us to coat large fabrications up to 2m3.
Paint-stripping station
We operate a highly effective paint-stripping facility. This is a submersion process into a stripping compound for ferrous metals and alloys. The compound is engineered not to attack or damage the base materials or previously applied treatments such as Alocrom or NCP.
Sand-blasting
We also offer a sand-blasting option in-house.
