Innovative corrugator technology with vacuum-forming technique for the production of perforated and unperforated material-saving corrugated or twin wall pipes for versatile applications in building construction and civil and underground engineering.
The advantages of the vacuum-forming process become particularly evident in the production of 

double or twin wall pipes that, worldwide, were first manufactured by HEGLER at the end of the 1960’s (first patent application in 1967 already).
In the production of complex partially corrugated profiled tubes for use in automotive engineering or industrial applications, these advantages are also of great importance.
