Pp/pc hollow profile sheets board production line1.pp/pc hollow profiles sheets boards extrusion production line is general suitable to make pp , pe hollow profile sheets , up to 10mm thick and 2500mm wide ; hollow profile sheet is widely used as advertising boards , decorating boards , roofing , packing and file materials ;extruderextruder its special extruding screw systems , precise manufacturing data , temperature controls and speed adjusting systems ensure stable good extruding ;diesdies excellent cr-plated heat resistant steel alloy is applied for t-dies , which flowing channels are of clothes-hanger type design , with excellent flow distributing systems , to make sure that flows can go evenly to all the whole dies ; a adjusting system equipped onto up and down die lips , to make sure that all sheets have good thicknesses ;vacuum forming tankvacuum former vacuum system and forming system are well designed and located ; equipped with a quick heat exchange die , forming systems and cooling system is well and precisely located among vacuum systems in good orders ; vacuum systems are composed of 2 independent sub-systems , each of them are equipped with many triangle type close-circuit vacuum tubes ; all close circuit systems are equipped with vacuum conditioning and monitoring systems , to make sure to have a stable and even vacuum degree on all sheet surfaces ;haul-off machinehaul-off machine the 1st one is big power and of big decelerate ratio , equipped with many rollers , it has a excellent low speed working , while its big hauling-off can draw sheets evenly out from vacuum former ; the 2nd haul-off draws sheets out from heating oven ; the 3rd and 4th haul-off are for transmission and unloading ;heating ovenheating oven ( annealing oven ) working together with the 1st and 2nd haul-offs , its multi-zones infrared constant temperature heating systems give good annealing to sheets , improving all sheets flatness ;cutting machinea precise auto short-time fixed length cutting systems and auto a lift type unloading system are equipped ;electronic controlelectronic control both panel control and plc control systems are chosen by our customershollow profile sheet is also called fluted sheet , corrugated sheet / board , twin-wall sheet , double wall sheet , carton plastic.

The lines have the advantages of well-planned layout, compact in structure, fine in performance such as homogenous plasticization, high output and long service life. The screws and barrels are made of special alloy and the structure is optimized. Exchanging screen rapidly about 1.5 seconds every times, the screen changer unit don't need the downtime. The cutting unit can guarantee the precise measurements through the adjustment of length and width, the error of product's diagonal
