Machine series for high-precision tubes

Horizontal flow forming machine

The HSTR series (horizontal flow forming machine) is used for high-precision tubes of high tensile and tearing strength in the most diverse and wide range of materials.

The HSTR machine series produces from simple, thick-walled tubes or rounds precision tubes with reductions in wall-thickness of up to 90%. The rotationally symmetrical hollow components at the end of the process have a workpiece diameter of 50 to 750 mm and a length specified to meet the customer’s needs.
