As for PP hollow sheet line, GSM equipment with it's own know-how, especially on the calibrators and annealing oven, The features are as follows:
1. The vacuum calibrator featured with wear-resistance, dirty free and the lifting, falling and leveling for the forming plates is much easier to be controlled.
2. High speed screw, low energy consumption with high rotation speed to match gear pump and stable pressure; Output capacity is 25% higher than other brand extrusion lines. Because of special design of forming plates.
3. Special designed cooling system for all section of forming plates, and unique designed vacuum system for each section of forming plate
4. Special designed temperature control oven with cross heat shrink forming, which is much easier to be controlled than other brand extrusion lines
5. The softness of pull rolls could be customized on request to extend its stretch
6. The air capacity of hollow sheet and low pressure could be adjusted and controlled slightly, which is easily to be controlled than any other brand extrusion lines
7. Unique T-Die is specially designed for PP hollow sheet. The thickness of hollow sheet could be from 2mm to 10 mm with twin-wall. The ribbed between walls could be rectangular and diagonal shape
