is a dry-paint process using, as the name implies, a powdered form
of paint. The powdered paint is electro-statically charged by a
special spray gun which causes the paint to stick to the part. The
painted part is then heated in an oven, melting the paint powder and
fixing it to the surface.
The process is simple and reliable, producing a high quality
finish. Due to the attraction between the paint and the part, the
paint particles are actively drawn to the target areas, even covering
edges that face away from the spray direction. This gives an even,
high quality finish.
Powder Coating can be used on a variety of materials and is
available in a wide range of colours, gloss levels and other types
Powder Coating produces a finish that is relatively hard,
abrasion resistant and tough. Whilst the paint is not chemically
bonded to the material, when correctly prepared and applied, it will
provide a long life. It is a highly cost effective, producing a paint finish
that will not crack, chip or peel.
Powder Coating is available in a wide range of finishes and
colours to suit most requirements.
powder coating facilities at Unimet enable us to provide a fast and
reliable service. Our staff are extremely experienced, producing a
consistently high quality result.
The spraying areas are kept scrupulously clean to prevent
contamination that might spoil the finish and our temperature
controlled ovens incorporate an automated conveyor system that
exposes painted components to heat for the correct amount of time,
ensuring a consistent, high quality finish.
In addition, we are happy to advise and help you to choose the
right paint for your particular application, to meet your requirements.
We can provide shot blasting to remove dirt, corrosion and old
paint finishes and vapour based de-greasing to ensure that parts are
clean and ready for painting.
For aluminium parts, we offer Alocroming which chemically alters
the surface of the material, making it suitable for the application of paint.
