PP PET Sheet Extruder PET PP Sheet Making Machine Plastic Sheet Manufacturing Machine
Classification of PET sheet extrusion production line:
1. Single screw production line for PET sheet: single screw extrusion production line for APET, PETG and CPET sheet is the most mature project with the most stable production at present. Generally, single extruder production line or twin-extruder production line is adopted and the latest technology to increase the general efficiency by 30%.
2. PET sheet single screw exhaust production line: this machine only needs to crystallize PET, and does not need to dry. Its advantages: low energy consumption, simple process, convenient equipment maintenance, and can ensure the blister 18CM deep cup.
3. The PET sheet twin-screw exhaust line (free from dry and crystallization) : It is launched PET sheet twin-screw exhaust line without drying and crystallization which has the advantages of low energy consumption, high efficiency.This machine is our continuous improvement upgraded products , and its central vacuum system has been upgraded. The original roots - water ring pump group upgrades to roots - rotary vane pump, which can make the vacuum degree reach 10 pa, or less. Meanwhile by using PET special alloy steel thin-wall roller unit can increase the cooling efficiency, so as to increase output, improve product toughness and transparency. Gwell's independently programmed operating system ensures that the device is user-friendly and easy to operate.
Forcing feeding unit
It is use servo motor connected with RV reducer system.
It is stable and possible to feed 1-4 kinds materials for extrusion.
Extruder
It is could be single screw extruder or twin screw extruder according materials.High production capacity of extrusion on the high quality basis. Lower temperature plasticizing design, ensure high quality sheet extrusion. Material of screw and barrel: 38CrMoAlA, nitrogen quenched (0.4-0.7mm ), Rigidity of screw: >740 , Rigidity of barel >940, the surface of screw is chromeplated Feeding bush with water cooling system
Metering pumb and filter
Metering pumb will control a stable extrusion pressure for whole system
The filter is double working station, no stop working for the extrusion line
T-Die
Die head is made according customer request width and thickness. Always it is 800-1200mm.
The brand will be Chinese top brand like JC Times
Calender
It is adopted 300-600mm diameters calending rollers, temperature is controlled by water.
The calendar roller driver adopted high quality motor and famous brand reducer.
The motor could be servo motor.
Auxiliary system.
It include the transport rollers,trimming unit, silicone oil coating, oil drying oven machine
Hual off unit.
It is use two rubber roller driven by servo motor units.
Automatic coiler
No of wheel: two wheel. The final design is made according materials and winding diameters
