USED PTI 6000

Manufacturer
PTI (Processing Technologies International) is a leading manufacturer of high-performance extrusion systems for the plastics industry. PTI extrusion equipment is widely used in sheet extrusion, thermoforming, polymer processing, recycling, and specialty plastics manufacturing, offering dependable performance, precise process control, and high production output.

Description
The Used PTI 6" Single Screw Extruder, Model 6000, is a heavy-duty industrial extrusion system designed for continuous thermoplastic processing applications. Built in 2003, this machine features a 6-inch single screw with a 30:1 L/D ratio, providing excellent melting efficiency, throughput, and melt homogeneity for a broad range of polymer materials.
The extruder utilizes an air-cooled barrel equipped with seven barrel heating zones to maintain consistent processing temperatures. An additional sixteen downstream heating zones provide precise thermal control throughout downstream processing equipment, making this unit well suited for demanding extrusion applications.
Power is supplied by a 400 HP WEG AC motor coupled with a WEG CFW-11 variable frequency inverter drive, delivering accurate speed regulation and energy-efficient operation. Torque is transmitted through a Flender Model SZNF 390 gearbox featuring a 21.7:1 reduction ratio and rated for up to 701 HP, providing exceptional durability and reserve capacity.
Additional features include a 9-inch × 7-inch feed throat, 62-inch centerline height, 900-amp disconnect, and V-groove casters for simplified positioning during installation or production line modifications. With an approximate footprint of 24 feet long × 100 inches wide × 106 inches high, this PTI extruder is an excellent solution for high-capacity plastics manufacturing operations.
