Thermoplastic resin is melted in a extruder and is helically wound as a band-shaped layer onto a pre-heated rotating steel mandrel. Higher wall thicknesses are produced by winding seperate layers whereas a homogenous clindrical wall results. This design guarantees a wound tube according to your technical demands.

 

Our production is supervised by an internal quality assurance, as well as by an external monitoring performed by the TÜV. The material properties and exact sizes of the tubes are controlled continously and are approved by issuing a factory certification according to EN 10 204 - 2.2.
