With Reifenhäuser Bitruders, you can produce pipes, profiles, sheets, pellets, and many other high-quality products very economically. Bitruders are the first choice when gentle material processing is required.



Technology
Gentle material processing.

Bitruders are operated with counter-rotating, intermeshing screws that enable the direct processing of powder. The technology is especially appropriate when it comes to the processing of temperature-sensitive compounds like PVC recipes.

Sustainability
Producing new products from waste material.

From plastic waste to park benches: New products such as planks, bollards, bank reinforcement or just park benches can be made from recycled polymers – for instance from waste collected in special recycling bags. You can process such waste material directly and without previous compounding in a single operation, from raw material to finished product.

Productivity
Direct processing of shear-sensitive materials.

Compounding is the only solution for shear-sensitive materials? Far from it: Thanks to the low screw speeds typical for the Bitruder technology, materials are processed in such a gentle manner that also extremely sensitive materials can be directly extruded saving time and energy.

Quality
Maintaining tight product tolerances.

Products with admissible tight tolerances require a stable production. The Bitruder technology perfectly matches this demand. Consistent product quality is ensured thanks to constant raw material feed rates at the intake, and steady output rates – perfect for the production of tolerance senstitive window profiles.

Reliability
Good wear protection. Long service life.

When manufacturing barrels and screws we adapt the steels to your specific application. Special hard wearing or armoured layers are additionally provided, depending on the fillers and reinforcing materials used in the extrusion process. Thanks to the high quality of the parts we can make long service lives possible to be obtained – even in the processing of PVC or WPC compounds.

Designs
Two systems offer high quality.

Reifenhäuser Bitruder technology comes in two designs. Both series combine compact, robust construction based on the modular principle, with userfriendly configuration.

Bitruder with conical twin screws
For lower output capacities

  • For lower output capacities
  • High energy input due to a large free volume in the raw material intake section
  • Low shear and control of high material pressures resulting from the reduced diameters at the discharge end

Bitruder with parallel twin screws
For higher output capacities

  • Variable barrel and screw lengths to suit various formulations
  • Constant peripheral speed, ensuring consistent melting behaviour
  • Excellent barrel wear protection for processing highly reinforced compounds
