Features | This production line adopts conical double-screw extruder, and it is capable of producing wave products with PVC powder material. PVC wave ?plate holds advantages of strong intensity, compact resistance, long life span, easy to execute and well decoration effect, which is widely used in fields of construction, decoration, and so on, and it is an ideal institute for asbestos shingle and glass steel tile. |
Extruder | Specially designed screw ensures the good plasticization, stable extruding and high output. Super noiseless air cooling system and compulsive closed loop cover of the barrel guarantee favorable heat conduction and discharge. |
Reduction gearbox | Reduction gearbox adopts sound insulating design. All gears were under high hardness treatment, and combined with compulsive lubricating system, to ensure that the reduction gearbox work steadily and quietly. |
Extruding mould | It is of special multi-channel design, which guarantees large width and stable extruding of plastic. The gap of die lip can be adjusted freely. |
Forming unit | The suitable design ensures quick forming and precise size. |
Tractor | The tractor is of simple two-roller design with the distance of rollers being adjusted freely. It adopts stepless frequency control, which ensures various extrusion speeds available to lay powerful guarantee on the stable operating after forming. |
Cutting machine | It is of reasonable cutting mode with blades of high quality alloy steel to ensure the quick, stable and flat cutting. |
Controlling system | Various kinds of controlling system are available to satisfy customers’demands. |
Width of products | 600mm-2000mm |
Thickness of products | 1mm-4mm |

First layer:The adoption of highly weather resistant engineering resin ASA PMMA, makes sure the surface layer has at least 10 years’ color stability, superior UV resistance, and excellent corrosion resistance as well.
?
Second layer:adopts high toughness to ensure both strength and rigidity
?
Third layer:?Good quality modified PVC materials with high toughness is adopted to ensure the strength while without compromising on the rigidity.
?
Fourth layer:adopts high toughness to ensure both strength and rigidity. The special material also offers a sense of space, and makes the building interior look brighter.

weatherproof ASA/PVC roof sheet, ASA Roof Tile is manufactured by one time processing through 3 or 4 layer co-extrusion technique. it has long lasting color stability and offers strong anti-UV performance to ensure long lifespan.also ASA PVC roof tile have charateristics such as easy cleaning, good thermal and sound insulation, as well as great resistance to water, fire, corrosion and contaminations. With high toughness, then can also withstand strong winds and shocks as well as heavy hails. the light weight makes sure they are easy for installation. Additionally, mainly make of ASA and PVC, this range of products is electrical insulating. |
