Premium extruder HELICAL for the best energy efficiency

Komax offers the HELICAL extruder family to all customers who are looking for maximum efficiency with excellent energy savings and incredible production outputs, high technological content and the highest quality of materials.

This technology has been developed at Komax for more than 10 years, to provide a higher material flow than both versions with smooth cylinders and those with straight grooves of same diameter.

Thanks to this significant increasing in production output, we have been able to notice several records in form of energy savings.

The development of the extruder, in the design of the screw and the cylinder, has been continuous and has allowed us to confirm this technology for the processing of the most requested thermoplastic compounds present on the market such as PVC, PE (HDPE, MDPE, LDPE), PP, PU, PA, TPV… including also flame retardants such as HFFR and LSOH.

HELICAL model extruders are characterized by a helical groove along the entire length of the barrel.
