Main Technical Parameters
Twin screw extruder
Degradable PLA, PET
One layer sheet, Multi-layers sheet
A real promising and profitable product for today’s packaging industry. The special extruder design enables the equipment to take into account two different raw materials of high temperature resistant PLA and low temperature resistant PLA at the same time.
The PLA sheet extrusion machine can produce PET sheet. Can be used as PET sheet extrusion line.
PLA Extruder-extrusion system
- The structure of screw, permutation and combination of screw elements, all designed by CHAMPION MACHINERY. With high hardness, high wear resistance.
- It suitable for PLA virgin material and mixing virgin material and recycled material. Special parallel twin screw for PLA makes the dispersibility of different material in the extruder.
- Free crystallizer and dehumidifier unit, no preheating the material.
- Venting system =nature degassing + vacuum degassing
- This vacuum system not only exhaust moisture of material in the extruder, but also exhaust the impurities in the extruder. There aren’t no spots on the surface of the sheet.
Pressure stabilization system
- From the extruder to T-Die, full pressure monitoring.
- Before the melt pump and after the melt pump, equipped with the pressure sensor. This closed loop control enables the extruder to adjust automatically.
- Two different types of winding system: manual work winder, automatic winder.
- The auto winder, equipped with SIEMENS servo motor control system. It’s more precise and has the function of speed synchronization with the whole line, which makes winding more convenient, simple and safe.
- Equip with independent research and develop auto winder, the line speed of PLA sheet extruder machine can be fast.
PLA sheet product can be used in vegetable container, fruit container, packages of consumer goods, an so on.
- SIEMENS S7-1500 control system.
- SIEMENS servo control and inverter control.
- The function of Key to acceleration makes the speed up of sheet line easier.
- Only one screen operation panel, operating easily.
