Description of PP PC hollow sheet production line:
Adopted suitable screw design and machine configuration, it is widely used in manufacturing PP or PC hollow profile boards of various specifications(Max. Width: 2500mm; Thickness range: 2mm-12mm). It is widely used in the fields of advertisement, decoration, sound-proof, packing. Because it is featured by light-weight, strong, damp proof, anticorrosive advantages, it trends to replace the paper carton gradually and become the first choice to make packing cases.
1、Extruder: The special designed screw and the advanced temperature control system ensure the good plasticizing, stable extrusion and high output.
2、Screen changer: It is of hydraulic style fast screen changer and ensures the short course of the exchanging filters. Double filters and special leakage-proof structure guarantee its stable performance.
3、Die: Made of super quality alloy and adopted adjustable restrictor bars, provide the even pressure of the plastic flow at the die lips. It ensures even thickness of the board with adjustable lips
