There are several different types of coating processes such as dipping, dip forming, spraying and co-extrusion. 

In the most basic coating process, a very fluid plastic paste is spread over a base material, or substrate (textile, paper, non-woven fabric,) and then passed through an oven to ensure that the paste forms a gel.

In the dipping process, the metallic shape is pre-heated before being dipped into a plastisol (liquid paste based on PVC and plasticiser ). This process is most particularly suited to PVC paste resins (emulsion and micro-suspension process), but powder dry-blends (suspension process) can also be used for specific needs.

Extruding can produce soft or rigid items which can be compact or cellular in form. Items which require specific characteristics ( f.ex. aesthetic appearance, good wheather resistance ) are made by the co-extrusion process which uses one ( jacketing of metallic wires) or two extruders and a specially shaped die.
