Powerful extruder ARC

KOMAX and DEXSEN offer the ARC extruder family for all customers that need combine very interesting production output with a wide flexibility of applications without lose a high technological content.

These extruders appeared in the beginning of the year 1980. They should achieve a higher flow volume with the same diameter of the screw present on extruders with smooth barrel.

The ARC extruders are engineered to work whether with thermoplastics (PVC, HDPE, LDPE, PP, PU, PA, PEEK …) or thermosets (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 expedient, combined with the profile of the barrier screw, considerably increasing the productivity of the machine.

Extrusion output of ARC extruder model

The production of ARC extruders varies according to the model chosen and the materials of interest.
The technical developments combined with the considerable experience of the KOMAX and DEXSEN team can guarantee production output ranging from 10 kg/h of HDPE to more than 1500 kg/h of PVC.

Extrusion screws for ARC powerful extruders

They are engineered with barrier profile and they work due to a fit of peak suitable with different compression ratios according the various materials to be extruded.
The KOMAX and DEXSEN screws are made of nitrided steel and they guarantee high production output as well as excellent mixing and plasticizing quality.

Barrels for ARC powerful extruders

They are engineered and produced to ensure a profitable combination with extrusion screws and excellent thermoregulation.
They are made in nitrided steel to guarantee a long life.
The high increasing of extrusion production is generated by a straight groove or helicoidal groove in the extruder feeding zone.

Motor and drive

All ARC extruders are equipped with high energy efficiency gearboxes and motors, to guarantee our customers low energy consumption.
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 internally by KOMAX to provide the maximum guarantee of quality and service to the customer.
