PP Hollow Grid Board Machine
PP Corrugated Sheet Extrusion Machine
PP Corrugated Sheet Extrusion Machine is an industrial plastic processing system designed to continuously produce polypropylene corrugated (hollow) sheets through extrusion and forming technology. PP corrugated sheets are widely used in plastic packaging boxes, turnover crates, bottle dividers, construction protection boards, appliance back panels, and advertising boards, thanks to their lightweight structure, high strength, water resistance, and recyclability. This machine integrates melting, extrusion, forming, cooling, and cutting into a stable, automated production process suitable for medium- and large-scale manufacturing.
Main System Components
The PP corrugated sheet extrusion system typically consists of:
1.High-efficiency single-screw extruder
2.Automatic material feeding system
3.Sheet extrusion die
4.Vacuum calibration and forming table
5.Cooling and conveying unit
6.Haul-off system
7.Online cutting or stacking system
8.Electrical control system with PLC and touchscreen
Each module works together to ensure stable extrusion pressure, uniform sheet thickness, and continuous production.
