Theysohn developed the “RK Streamliner” pipe head with the following advantages for our customers production.
higher melt pressure after the torpedo and therefore a much better welding effect
based on the higher melt pressure after the torpedo, high melt pressure in the die set is no longer necessary for achieving optimum pipe quality
shorter die sets
wider pipe diameter range for each pipe head
modular system: use of die set of the nearest smaller pipe head
fast mandrel exchange to adjust wall thickness of end product
30 – 35 % less volume of head reduces resistance time of material resulting in a reduction of stabiliser
The new pipe heads “RK STREAMLINER” can be used for single and double strand extrusion. The PVC pipe head RK is still available.
