High output extruder ARC

KOMAX and DEXSEN offer the ARC extruder family for all customers who need to combine significant production output with a wide flexibility of applications, high technological content and the excellent quality of materials.

These extruders were initially developed at the beginning of the 1980s. They achieve a higher flow volume with the same diameter of the screw present on extruders with a smooth barrel.

The ARC extruders are engineered to work both with thermoplastics (PVC, HDPE, LDPE, PP, PU, PA, PEEK …) and thermosetting materials (XLPE, XLPO…), also including flame retardant compounds (HFFR, LSOH, XL-FR…).

The ARC extruder models are distinguished by their groove in the barrel feeding zone.

This particular design, combined with the profile of the barrier screw, considerably increases the productivity of the machine.

Which applications are available for Komax high output extruder ARC?

An ARC extruder can be used as the main machine of the line or as an auxiliary machine, in order to apply an additional layer of material or a stripe, working in co-extrusion with another machine.

Specifications of Komax high output extruder ARC

Komax high output extruders ARC are available in various models and with a whole range of specifications, so as to perfectly satisfy your needs.

Available models of ARC high output extruder

KOMAX and DEXSEN provide a wide range of ARC extruders so that even the most complex application can find an efficient solution.

Extrusion screw diameters range from 20 mm to 160 mm, with a barrel length of 26D.

Extrusion output of ARC extruder model

The production of ARC extruders varies according to the model chosen and the materials in question.

The technical developments combined with the considerable experience of the KOMAX and DEXSEN design teams can guarantee production outputs ranging from 10 kg/h for HDPE to more than 1,500 kg/h for PVC.

Extrusion screws for ARC high output extruders

They are engineered with barrier profiles and they work with different compression ratios suitable for the various materials to be extruded.

The KOMAX and DEXSEN screws are made of nitrided steel and they guarantee high production outputs as well as excellent mixing and plasticizing quality.

Barrels for ARC high output extruders

They are engineered and produced to ensure a useful combination with extrusion screws and excellent thermoregulation.

They are made of nitrided steel to guarantee a long life.

The high increase in the production of the extrusion is generated by a straight or helical groove in the extruder feeding zone.

Motors and drives

All ARC extruders are equipped with high energy efficiency gearboxes and motors, to guarantee a low energy consumption for our customers.

Liquid-cooled gearmotors are available for the highest energy efficiency with the maximum containment of noise levels.

The use of the latest generation of Siemens and Lenze drives complete the combination for the control and management of speed and torque on the extrusion screw, further reducing consumption.

Electrical and control equipment

All models are completed with electrical equipment produced in-house by KOMAX to ensure the maximum guarantee of quality and service to customers.

  • The KOMAX and DEXSEN programs are based on the most recent Siemens protocols and they allow quick installation of the machines, even on existing lines
  • A rich exchange of information with the plant network ensures that our extruders are in accordance with Industry 4.0
  • Easy use of the machine is guaranteed by a large and intuitive 12” and 15” touch screen, which is capable of displaying production process graphics in real time.
  • Versions with thermo-regulators and potentiometers on board the machine are available on request.
