PET/RPET/APET/CPET/PETG sheet extrusion line

1) High-quality PET sheet produced using 100% bottle flakes
2) Raw material handling system includes the raw material storage, drying, gravimetric dosing, automatic multi-stations loading system. The gravimetric dosing system for raw material handling, can realize proportionally precise mixing of several types of raw materials components.
3) Extrusion system: To suit the client’s different requirements, we can offer the screw diameter from 45mm-150mm, L/D ration from 30-35. On the other hand, we install double pillars type hydraulic screen changers, melting gear pumps and also static mixer as well for mixing the material well and maintaining average temperature.
4) Flow direction adjustable feed-block and layers changeable option to fit two or three extruders and offer best combination of thickness into multi-layers sheets.
5) Roller calendars: the arrangement of the roller calendars can be horizontal type, oblique type or angles type.
The temperature control uses the individual temperature controller, relative speed control, which offers even thickness and reduce die line. .
6) The online side trim granulator and pipeline conveying system can convey the side edges to the front extruder automatically.
7) Sheets accumulator design for higher line speed
8) Central winding mechanism adopts two winding shafts. It adjusts the tension during winding. Both 3’’ and 6’’ paper cores are applicable to this machine.
