Used Davis-Standard 60IN60TPIH 6" Single Screw Extruder – 34:1 L/D, 400 HP, Vented Barrel with ABB Drive

Manufacturer

Davis-Standard is a globally recognized manufacturer of extrusion systems serving the plastics, polymer, packaging, pipe, profile, sheet, wire and cable, and recycling industries. Davis-Standard extruders are known for their rugged construction, advanced process control, and long service life in demanding continuous production environments.

Description

The Used Davis-Standard 6" Single Screw Extruder, Model 60IN60TPIH, is a high-performance industrial extrusion system designed for high-output thermoplastic processing applications. Built in 1994, this machine features an extended 34:1 L/D ratio and a vented, water-cooled barrel, making it well suited for processing moisture-sensitive materials, recycled plastics, and applications requiring devolatilization.

The barrel incorporates six water-cooling zones, with the vent located approximately 130 inches from the center of the feed throat. The vent is currently plugged but can be utilized for vacuum venting or devolatilization applications if required. The cooling package includes a 1/2 HP recirculation pump, heat exchanger, and integrated water reservoir measuring approximately 32" × 24" × 12".

Power is supplied through a 400 HP WEG AC motor operating at 1,790 RPM, coupled to an ABB AC variable frequency drive for precise speed control. The extruder utilizes a Davis-Standard Model 60IN60TPIH gearbox with a 17.2:1 reduction ratio, rated for 526 HP with a 1.5 service factor, providing dependable torque for demanding extrusion applications.

Temperature control is managed through six Solo 4896 barrel zone controllers and seven Omron E5EC die zone controllers. The operator station includes a speed pod displaying screw RPM, motor load percentage, and pressure transducer readings for comprehensive process monitoring.

Complete with a hopper, 42-inch centerline height, and an approximate footprint of 25 feet long by 8 feet wide, this Davis-Standard extruder is an excellent choice for manufacturers seeking a proven, high-capacity extrusion platform.
