Greenlandplast Pet Straps Production Line Plastic Strap Making Machinery

                                     Greenlandplast pet straps production line plastic strap making machinery
This PET strap extrusion line adopts advanced comby dehumidify dryer system. It make sure the material humidity at 80PPM at 50PPM dew point. Meanwhile,itcompact material and increase the viscidity.Adopts closed cycle transport system after dryer to avoid contact with outside air and make sure the material be dry continuously.Extruder adopts special screw for PET. The screw has unique separate and mix property to make sure uniform plasticizing. The screw suitable for recycled PET bottle flakes, PET mixture and original PET material. 
Mold can  produce different model product from 9-20mm witdth PET strap. Equip hydraulic screen exchanger without material leak.
Static cooling roller replace the water cooling tank. The roller will cool the strap at the constant temperature. It improves the product's stretch intensity.
The strap after formed will be warm and anneal treated to wipe off the part stress remained after stretch. It makes molecule tropism be steady to avoid strap distortion caused by storage.
The winder adopts double work position and auto-meter. It is easy operation and convenient coil change.
Centralized electrical control, PLC self-correcting control. Easy operation.
