Description
Description of PP Hollow Sheet Production Line
Our PP hollow sheet production line is designed for the continuous production of PP/PE/PC hollow grid sheets and corrugated plastic sheets. The line delivers consistent output with smooth surface finish, uniform internal rib structure, and precise dimensional control. It is suitable for manufacturing packing boxes, turnover boxes, advertising boards, construction formwork, and various industrial applications.

High-Efficiency Extrusion System
The production line adopts a 38CrMoALA nitrided screw and barrel, ensuring uniform melt plasticization and stable output. The precise PLC control system enables closed-loop control of screw speed, ensuring a smooth transition from startup to steady-state production and effectively reducing the startup scrap rate.
Precision Vacuum Calibration System
A dual-zone independent vacuum cooling system is adopted, with each subsystem equipped with independent cooling water circulation and variable-frequency vacuum adjustment. The surface of the aluminum calibration plates is specially treated to combine wear resistance with excellent heat exchange efficiency, ensuring uniform upper and lower wall thickness and neatly formed internal ribs.
Energy-Saving Design
The core heating zones use electromagnetic heating technology, which can reduce energy consumption by approximately 30% compared with conventional resistance heating. The power configuration of the entire line is optimally matched to avoid unnecessary power waste.
Recycled Material Compatibility
The production line supports a recycled PP incorporation ratio of up to 30%. Combined with a stable plasticization system, the mechanical properties and surface quality of the sheets still meet application requirements after recycled material is added. This feature can help customers significantly reduce raw material costs.
