Detailed Descriptions
PP/PS sheet extruder system
- Single screw extruder of PP/PS sheet extrusion machine is the main model in the market. For PP material, use non-venting single screw extruder. For PS, use venting single screw extruder normally.
- Independent R&D high efficiency single screw extruder, with good plasticizing of raw material and formula. Ensure the good toughness of plastic sheet.
- The capacity of CHAMPION single screw extruder can reach 1500kg/h.
- Twin screw extruder also can be used for PP sheet.
- CHAMPION MACHINERY, the screw structure of twin screw extruder is more flexible. It makes the feeding more stable, at the same time, formula material and mixed PP recycled and virgin material will have the better dispersion in the barrel.
PP + starch sheet making machine
Add the starch, the final sheet will be new biodegradable material. The final product can be used for food containers.
Roller calender forming unit
- According to the sheet product, choose mirror surface roller, grinding roller or woven roller. High quality roller.
- The Max. diameter of roller can be 800mm.
- The high-precision three roller calender forming system, equipped with SIEMENS servo control, hydraulic adjusting, is suitable for the stable extrusion of PP/PS sheet.
- Tolerance of temperature for roller is ±1℃.
- The screen panel installed on the calender unit, operate the sheet machine by only one HMI.
Winder
- Single working station heavy roll winder, double working station manual winder, three working station manual winder, auto winder
- Auto winder, auto working, more safety and accuracy.
- Sheet length is control by PLC.
Control System
- PLC control.
- A key to accelerate: through the button in screen panel, speed up the line speed very easily.
- Electric cabinet: it completely uses high class and qualified accessories. Its vertical type of design structure is good for heat dissipation.
- Remote control and remote fault diagnosis, makes debugging easier and maintenance more convenient.
