THE MASKING PROCESS
The process of masking metal components so that areas such as gasket surfaces, internal & external threads and bearing surfaces are not powder coated has moved on from the days of a man with a roll of paper masking tape and a Stanley knife laboriously cutting and sticking bits of tape here & there sometimes accurately but most times not.
Powder Coatings Ltd are able to offer comprehensive Powder Coating Masking advice for any requirements you may have, we source products from all the major masking suppliers as well as commissioning bespoke masking solutions for components that cannot be masked using off the shelf materials.
Reasons for Powder Coating Masking
Powder Coating Masking is required for a variety of reasons;
- Parts that need to fit together: and have tight tolerances such as two tubes that form an assembly.
- 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.
- 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 procedure after the powder coating process.
- Gasket surfaces: many machined components that fit 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.

Important Information About Masking
Another important issue to remember is the masking information supplied by the customer to the powder coater. Very often Powder Coating masking requirements are an ‘after thought’. The coater will be supplied the drawing or sample component and generally informally told that a particular thread or holes need masking. This is not very efficient and if not fully understood can result in parts that are not masked to customers’ requirements causing delays and unnecessary rejects.
The best way to inform a coater exactly what parts or areas need masking is to produce a bespoke powder coating masking drawing and add it to the drawing register for the part.
With Computer Aided Drawing Systems it is relatively easy to highlight in a different colour the specific areas, threads or spigots that do not require coating. The coater can attach this drawing to his Route Card so that all works personnel are fully informed about the specific masking requirements.
