Single Screw Extrusion Special and flexible product and application range

Single Screw Extrusion

Single screw extruders and cascade systems are used in all modern Brückner biaxial stretching systems. Over the past years, Brückner Servtec has conducted very successful upgrades with coextrusion enhancements for various customers around the world, using single screw extruders with a multi-purpose or a special-purpose screw design.

The single screw extruders are available for PP, PET and PA films. The cascade systems are also suited for PET optical and PP-Capacitor lines.

 

They are the best precondition for high process constancy, high melt quality and the production of multilayer films with the highest quality. The output amounts to 1,200 kg/h for PP-Capacitor film and 6,000 kg/h for PET optical film.
