This extrusion line consists of single screw extruder, melt-pump, hydraulic filter exchanging unit, hollow
sheet die head, vacuum calibrating table, first haul off machine, oven, corona treating unit, cooling table, second haul off machine, trimming and length-settled cutting units and stacker etc.Characteristics of vacuum calibrator:
1. High quality mould steel or high strength Al-Mg Alloy
2. Special harden treatment and non-sticky coating on the surface.
3. Independently controlled vacuumize device and temperature controlling system.
4. Consist of vacuum sealing edge device.T
The technology of hollow sheet die with co-extrusion feed block to get UV+PC+UV, UV+PC hollow sheet can save 30% UV on the surface.

Application:
PP/PE hollow sheet is light and high strength, moisture-proof, good environmental protection and re-fabrication performance and can be used into the reusable container, packing case, clapboard, backing plate and culet.
PC hollow sheet is widely used in construction sunroof in buildings/halls/shopping center/stadium/public places of entertainment and public facility; Ring shield of bus station/garages/pergolas/corridors; noise barriers for highways and urban elevated road
