Whether pressure pipe or drain pipe, conduit or sewer in most cases plastic pipes, either PVC or Polyolefin, are the perfect choice.

We understand that to be successful pipe producers and suppliers. It is important to produce high volumes of reliable quality pipe with a cost-efficient process. That is why we’ve partnered with Krauss Maffei who focus on designing machinery with high capacities, high tolerance precision and a homogenous melt reducing scrap rate and reducing overall costs.

Our scope of supply extends to:

Extrusion systems
Process development
Automation
Tempreture control & cooling
Raw materials handling

Extrusion technology

QuickSwitch technology for in-line dimension changes delivers maximum flexibility and minimum cost for pipe extrusion.

The requirements relating to pipe extrusion are already very high nowadays: small order batches, high flexibility, long production times and cost-efficient production are imperative.

Whereas conventional pipe extrusion lines have to be stopped, converted and restarted with every
change of dimension, the efficient QuickSwitch technology from KraussMaffei Berstorff can be used to change the pipe dimensions during continuous production – simply at the push of a button. This effective and intelligent technology generates potentially enormous savings.

In addition to investing in a complete machine, existing lines can be changed by adding individual modules and extended into a fully automatic machine using the manual version of QuickSwitch.

Your advantages at a glance:

  • Greater flexibility thanks to dimension changes at the push of a button
  • Higher productivity through shorter stoppage and changeover times
  • Lower material cost through reduced scrap
  • Lower labor costs by saving time and personnel
  • Low capital tie-up due to low stocks
  • High delivery availability thanks to small batch sizes

All-in-one control system:

Overriding control system

The overriding control system is a key element of a fully automatic QuickSwitch line. All QuickSwitch functions are integrated in an overriding C6 control system. Here, for example, the following parameters of the extrusion lines are stored once for every individual pipe dimension:

  • Raw material
  • Output rate of the extruder
  • Pipe dimension
  • Pipe head adjustment
  • Underpressure in the suction bell
  • Diameter in the calibration basket
  • Position of the vacuum tank
  • Underpressure level in the vacuum tank
  • Haul-off speed
  • Contact pressure of the haul-off caterpillars on the produced pipe

PVC pipes have a wide variety of uses and many benefits. PVC is safe for drinking water, has a longer lifespan than competing materials, is a recyclable material, has lighter properties and is more cost effective to produce, transport, install and maintain.

Our technology benefits:

  • Low maintenance costs thanks to internally heat-balanced screw and air-cooled barrels
  • Safe degassing even with highly filled mixtures
  • Wider processing range of different formulations and materials thanks to high process flexibility
  • Increased cost-efficiency thanks to a longer service life of process unit
  • Optimal wear resistance of the molybdenum welded layer
  • High output rate with perfect product quality
  • Excellent price-performance ratio

PVC multilayer pipes allow for use of a foamed core layer to reduce overall weight leading to material saving in non-pressure applications. Up to 100% of the core layer can be inhouse or post-consumer regrind or can be modified with high filler loads of up to 100 phr.

Benefits:

  • 30-40% material cost saving
  • 20-30% weight reduction

Powerful machine technology, flexible application
