Innovative single screw extruders
USEON deveoped single screw extruders with some new features. Most of them are pointed to energy saving, productivity and process control.
► Optimized extrusion unit design to maximize output and keep melt lower termperature
► Direct Coupling with overload protection if necessary ► Precise Temperature Controlling System, water cooling solution available for special cooling extrusion ► Convenient Installation And Adjustment
TDD series extruders are divided into the followed four sub-models according to different applications.
TDD-A standard extruders
Main features of TDD-A include smooth feeding barrels, typical screw profile. Mostly, some mixing sections are designed for the metering section to get better mixing and homogenization. The standard L/D is designed to 30. Presently, our maxium standard extruder is TDD250A to be appied in BOPP film extrusion line with output 5000kg/hr.
TDD-P venting extruders
This series extruders are mainly purposed for the polymers that requre venting or vacuum extraction during extrusion process. Typical applicaitons include recycling extrusion and product extrusion, mostly for PET, PA, ABS, PC, PA.
TDD-K grooved extruders
With grooved barrel in the feeding section and also the barrier screw profile, TDD-K series extruders could approach very high output and with lower melt temperature. This series extruders are mainly applied for polyolefin or dried engineering plastics to extrude films, sheets, plates, pipes or profiles. Same diameter extruder could get more than 2 times output with such design. However, the maxium diameter is limited to 180mm.
TDD-R melt cooling extruders
In some cases, like foam extrusion process and heat sensitive mateiral compounding process, and even for some BOPP/BOPET extrusion process, melt cooling extruders are necesary for strict elt temperature controll. USEON is going to manufacture one TDD400R cooling extruder for XPS extrusion process to get 1000kg/hr output.
