Cutting-edge FLEXT Series Extruders

Flexplas proudly offer a wide range of FLEXT Series Single-Screw Extruders, either as a stand-alone extrusion machine or as part of a complete extrusion-system. All Flexplas extruders are characterized by an open, robust, and proven construction and high-quality craftsmanship. Screw diameters from 20 to 120 mm and process lengths of 25D to 30D combined with the appropriate screw geometry guarantee excellent plasticizing and maximum output for all popular thermoplastics. Digital, self-optimizing PID temperature control and a blower cooling system ensure outstanding process stability. Other features include Sliding hopper, ceramic heaters, screw designed for every type of material, energy-saving system, digital extruder control with touch screen.

Flexplas FLEXT-series extruders boast many a feature as standard. We also present various customized options for our customers to meet their production requirements.

PLC with color touch screen control is simple to operate and provides you with total control over hose production. All production data is captured and can easily be exported for analysis via Ethernet and SCADA System. Access to as little or as much data, settings, alarms, etc. is for you to decide – you are in control. Change the language of the control system at the touch of button. PLC touch screen provides line operators with the most comprehensive and easy to use control system available.  

We offer a wide range hi-tech and sophisticated single screw extruders for a wide variety of required end product.
