PP , PE hollow profile sheet ( cartonplast ) extrusion line
1.
General Suitable
to make PP, PE Hollow Profile sheets ( cartonplast sheet , Corplast sheet ) up to 10mm
thick and 3M wide ; hollow profile sheet is widely used as advertising boards ,
decorating boards , roofing , packing and file materials ;
2 . Extruder
Its special extruding screw systems , precise manufacturing data ,
temperature controls and speed adjusting systems ensure a good
plasticatings and stable good extruding ;
3.
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 and even up and down wall thicknesses ;
4.
Vacuum former
Vacuum
system and forming system are well designed and located ; equipped with a quick
heat exchange die , forming systems’ 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 ;
5. 4
haul-offs 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 ;
6.
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 ;
7.
A precise auto short-time fixed length cutting systems and auto a
lift type unloading system are equipped ;
| 8.
Electronic control both
panel control and PLC control systems are chosen |
|
by our customers, all data of
whole line ( such as rpm of screw , temperatures , pressures , capacity…) can be well
controlled , thus the whole line can work together perfectly .
9.
Hollow profile sheet is also called
fluted sheet , corrugated sheet / board , twin-wall sheet , double wall sheet , cartonplast
.
