PROCESSES

Surface Dynamics supply products and services for the removal of coatings and contaminants, or the beneficial mechanical processing of a surface, by the impact of selected particles, or'media', in a compressed air stream.

Paint, Coatings and Contaminant Removal

Removal of all types of paint, adhesive residues, tedlar film, special heat or wear resistant coatings, metal spray, heat scale. Almost any application where the coating is of a different hardness to the substrate or the bond between the coating and the substrate can be disrupted.

Deflashing and Deburring

The removal of flash or resin spew in plastic mouldings and resin composite manufacture, removal of metallic burrs and debris from machining and laser cutting.

Surface Peening

This process relieves tensile stresses in the surface of metals to increase fatigue resistance. Can also be used to form curved metal panels without stress fractures or provide uniform 'satin' finish on components.

Surface Etching

This is providing a uniformly rough micro surface onto which paint, metal spray or similar coatings can easily bond. The substrates are usually metallic but also can be plastic and resin composites for coating and adhesive bonding.

Corrosion Removal

Removal of corrosion on steel, aluminium etc. so that items can be coated with paint or a similar protective layer and extend their service life.

APPLICATIONS

Electronics

  • Removing resist film and plastic flash in PCB and
    semi-conductor manufacture.
