Cleaning

NSP Coatings Ltd carry out degreasing and shot blasting for both applications that require coating as well as stand alone jobs. Some examples are detailed below.

Shot Blast Only

These sheet metal and tube components have been shot blasted to Sa2.5 standard with chilled iron grit in order to provide a rough surface and key prior to coating at the customers premises. Surface abrasion is often required for providing a better bond between the coat and the metal.

Degreasing

To remove the protective oil that protects sheet metal during storage as well as the oils applied during the punch, fold and fabrication processes sheet metal products are cleansed using a vapour degreaser prior to powder coating or wet spraying.

Aluminium Castings Cleaning

We carry out blast work on new aluminium castings prior to anodising. The blasting removes wax or sand deposits as well as smoothing burrs and excess aluminium left behind from the casting process. An example of more recent work in this area includes the blasting of hose tips for fire fighting equipment.

Car & Motorcycle Wheels

We offer a wheel cleaning service for cars and bikes, shot blasting existing paint, rust, corrosion and providing a well etched surface for a coating. This service is available to the trade as well as the general public although all tyres and tubes must be removed and in the case of motorcycle wheels all bearings, seals and hub units must be removed prior to coating. Available finishes include gloss, matt, metallic and lacquer.

Gates

The two gates show the before and after of the shot blasting process. The cleaning process removes paint, rust, grease, corrosion and dirt leaving the surface clean with a well etched surface suitable for powder coating or wet spraying. Most metalwork that is shot blasted requires coating within 4 hours, depending on the humidity, in order to seal the bare surface from oxidation and the initiation of corrosion.
