Quick tips on PVC ASA roofing
The plastic PVC ASA roofing refer to a new composite roof tile
products, which is mainly made by plastic extrusion and forming
machine.It has various pattern of appearance(like circular, rapzoil
shape,and also glazed shape) and colors, but is much cheaper
than other tiles made of ceramic, clay and metal in same
square meters of roofing coverage.
At the same time, the plastic roof tile will not have any problem
for the environment, instead, using a group of plastic sheet
recycling machine which we also called plastic auxiliary machine
such as plastic sheet crusher and miller, the waste of damaged
roofing sheet can be recycled to feed the production line
again as the middle layer to save the cost. Meantime, the
filler material used in plastic roofing products is calcium
carbonate which is very cheap and available almost anywhere, and it
costs USD100 per ton.
PVC ASA Plastic Roof Tile Extrusion Line
The bestseller machine in Acemien factory is the plastic roof tile
machine, due to its outstanding performance of the products and
machines, these roof tiles are very popular across the world, here
we explain the production line by three steps as shown below:
1,Raw Materials preparation
Using our high efficient reliable vertical raw material mixer,
the raw materials such as PVC powder,Calcium Carbonate, and other
additives like cloride PE, pre-wax, stearic acid, compound
stabilizer, ACR, Paraffin are mixed together and homogenized,
which is very important in sheet making, because the improper
mixing would lead to product deficiency problem like crack,
bubble and bump.
2,Co-extrusion for multi-layer
In this stage, the completely mixed raw materials are
transported, molten and fully plasticized, and then
transferred to the sheet die mould due to extruder pressure caued
by rotating screw, where the sheet thickness can be adjusted
between 1mm to 3mm through screw of mould lips, finally the ASA
coating layer is formed on the surface of roof tile.
3,Forming and cutting
In the final stage, the hot PVC ASA sheet is tracted to the tile
forming machine with glazed mould after trimming, in which the wind
generated by the cooling fan at both side will blown into a tunnel
to cool down the temperature for the glazed mould after absorbing
the heat from the running hot roof tile sheet, and then the formed
glazed PVC tile sheet continues to be tractedto a cutting machine,
where a certain length of the glazed roof sheet is cut as per PLC
programmed, and finally the glazed roof sheet are piled on the
stacker table which is ready to be packed.

PVC ASA roof tile advantage
1,Anti-corrusion,will not rust like the iron or metal tile.
2,It works for 25 year.
3,Easy to install and transport.
4,Heat resistant due to low conductivity of the roof sheet.
5,Used As durable weather sheet, and also for counterpart of wall
panel sometimes.
6,Noise proof when it rains and winds.
7,Heavy load bearing even to heavy snow,rain and falling objects,
strong enough to hold against Typhoon.
8,NOT leaking.
9,Nice appearance with bamboo shape.
10,Environment friendly, can be recycled by plastic crusher and
miller to be reused to extrude middle layer ,then to reduce
manufacturing cost.
11,Anti Ultraviolet.
