Providing high quality and expert powder coating services across the Midlands and beyond.

Many manufactured parts have areas where no coating is required. Prior to any further preparation the first step is to mask these areas. Masking parts has moved on from the days where a person armed with a roll of sticky masking tape and a Stanley Knife would crudely attempt to cover areas or holes where coating was not required.

These days there are masking material manufacturers who produce all manner of masking materials;

High temperature tapes that leave no sticky residue.

Silicon bungs and caps of all sizes and shapes.

Die cut masks that exactly cover intricate shapes.

These are used in a variety of different situations such as;

Parts that need to fit together and have tight tolerances such as two tubes that form an assembly.

Parts where Powder Coating on mating surfaces would impede them fitting correctly and result in wasted time/effort cleaning the mating surfaces.

Holes or recesses that have bearings fitted into them; Bearings are usually a ‘press fit’ and the inside diameter of the part that accepts the bearing must be the correct dimension.A build-up of Powder Coating can interfere with the fit and residues of powder that are removed/loosened during the fitting process can block the bearings and stop them running freely.

Internal or external threads; if a thread is coated with powder this will cause problems during the assembly process. Removing powder coating from tapped holes or threaded surfaces is extremely difficult and can waste a huge amount of time and slow down the assembly process after coating.

Gasket surfaces; many machined components that have to be fitted together have surfaces that require gaskets or seals between the two components. The mating surfaces have to be kept free of Powder Coating to ensure that no leaks occur and that the components fit together precisely.

Electrical Earthing; All metal electrical components or enclosures require an ‘earthing point’ This is an area of the component surface that has no coating applied so that an earth tag or connection can be fixed to the surface of the part ensuring the part can be used safely.
