PET sheet extrusion - Without predrying
New but sucessful technology for PET direct extrusion without crystallization
USEON's unceasing efforts to design the best extruders to adapt the PET extrusion make us advanced in sheet extrusion technology and equipments. Combined with simplification of the flow chart, our PET sheet extrusion avoid the predrying units and crystallization units. This not only simplifies the systems and also reduces energy involved for predrying system.
USEON's twin screw extruders to plasticatingwithout predrying
TDY counter rotating twin screw extruder is different from normal one. It features high speed, higher capacity, and more applications. TDY can extrude sheet, board, film directly without pre-dry. It has significant advantage in energy-saving. Addtionally, more advantages are even more interested as per below.

Dramatic energy-saving
When we talk about the differencebetween the traditional solution with crystallization systems and the direct extrusion solution with twin screw extruders, the energy saving could be easily calculated. The typical power for predrying unit and crystallization is about 0.2kwh/kg, however the degassing units for twin screw extruders just consumes about 0.048kwh/kg. The total energy comsupmtion differene could be up to more than 40%.
Advanced Sheet/Film Technology
With particular technology and engineering experience, USEON develops and perfects the sheet/film extrusion line. The main advantages are the compounding and pelletizing technology of twin screw extruder. Integrated with advanced control system, its post stretch and calibration also have excellent performance. USEON did better more than whatyou have expected.
