Description :The rotating screw extruder pushes the plastic beads entering through the feed throat forward into the melting barrel. This allows the plastic beads gradually melt under controlled progress through the barrel, at closely controlled correct melting temperature for the polymer.Ozmak extruders range from 50 to 130 mm in diameter with capacities of 300 to 1000 kg/h. The Ozmak extruder technology provides close control of melting temperature with +/- 1°C by means of a custom cooling system designed specifically for full circulation of air for high efficiency, fast cooling rate.Ozmak extruders can handle various material mixes including scrap in order to get good quality for lower material costs while enabling the same production speed and control with all mix types. Thanks to our custom feeding zone design with specially engineered hopper and screw geometry, the heterogeneous material mix flows smoothly through the screw.Screw and barrel gets the material to the needed production temperature while moving it forward. Ozmak screws have the additional mid barrier between main helices with wider surface for better heat transfer while maximizing compression. Thus Ozmak design differences with years of experience accumulation help better flow and efficient output.
