- Any basic spiraled hose will consist of a plasticized PVC wall and a rigid spiral
- The two molten materials are conveyed into an extrusion head, pushed through a die and the profile is wound around a mandrel to make the hose wall.
- The hot extruded profile, because of its shape, when overlapping with the next turn and squeezed by a roller, will weld together and a hose is born.
- By extruding a flat profile on the mandrel first, a hose with an inner liner is created.
- Here various compatible materials can be used for specific purposes like abrasion or friction characteristics or color contrast, just to name a few examples.
An additional copper wire will allow earthing for dissipation of any static build-up.
