SJ35-Desket is only the SJ35 extruder on the very left.
G-Pelletizer is a machine used to cut the filament into pellets, tractor function built-in (there is No need for an extra filament tractor).
SJ35-GL is the whole above 3 parts and the water cooling tank you can find in the picture.

PET Recycling Practical Notice:
The SJ35Line filament production line can be used for PET Recycling. About the tolerance, it's practical to adjust the speed of the extruder and the tractor, because the extruder and the tractor do not have a synchronously controlling system. Our practical tolerance could be +-0.05mm.
1. Make sure the temperature of the screw and barrel zone reaching the melt for the PET and then to start the Extruder. Temperature does Not reach may cause the extruder, especially the motor getting hot, also the screw is easily worn out.
2. You need a hot water supply in the cooling tank, to keep it 60-70 centi-degree would be good, we use an induction cooker to keep warm. :-)
3. Keep the extruder and the water tank as close as possible, then the filament can be cooled down ASAP.
4. The temperature of the DIE (Nozzle) as lower as the extrusion can be extruded out.
5. Make sure the filament between the extruder and the tractor tightly and submarine the hot water in the cooling tank.
