1.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 ;
extruder
extruder its special extruding screw systems , precise manufacturing data , temperature controls and speed adjusting systems ensure stable good extruding ;
dies
dies 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 tank
vacuum 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 machine
haul-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 oven
heating 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 machine
a precise auto short-time fixed length cutting systems and auto a lift type unloading system are equipped ;
electronic control
electronic control both panel control and plc control systems are chosen
