Description

When comparing a twin screw extruder to a single screw extruder, the single screw extruder retains its own status during many applications. We offer different types of single screw extruders including general purpose single screw extruder, venting extruder, and grooved extruder. At Useon we have a wide range of single screw extruders from 20mm up to 400mm in diameter, and 5kg/hr up to 5,000kg/hr.

Newly designed TDD series high efficiency single screw extruder have been endowed with innovative features which mainly focused on energy-saving, more accurate process control, and higher output.

Our experts will give professional advice for your individual application. Trust our experience with your single screw extruder needs. Speak with us directly today to begin the process.

A brief summary of what advantages we offer includes:

  • Lower specific energy consumption, 30% less than traditional extruders
  • Greater output which can be increased by 50% on the basis of same screw diameter
  • Superior plastication
  • Better mixing effect
  • Precise and accurate process control
  • Wider application including recycling, compounding, pipe extrusion, and sheet/film extrusion

Product Model

TDD-A series are standard single screw extruder for general purpose plastication and extrusion. To strengthen the mixing effect, we have added mixing flight in metering zone.

Typical L/D is 30, and the max diameter is 250mm which is used in BOPP extrusion and yield 5000kg/hr.

Grooved barrel will increase the capacity significantly, it could be double compared to standard single screw extruder. Because of its powerful convey capacity, the processing temperature can be kept lower level.

This kind of extruder is normally used in polyolefin processing and some engineering plastic extrusion molding.

TDD-R is designed for polymer cooling process.
According to different cooling capacity, we will employ different L/D, different cooling channel design. They typical applications are foam extrusion, heat-sensitive and shear-sensitive compounding.
