Through the above technology sheet, we known that there are many
factors for choosing the right model of PVC pipe extruders for
making different diameters pipes. The primary reason is that saving
PVC pipe making process cost , customers would like to choose
higher output extruder machine with lower energy consumption.
Magstar Machinery can provides all necessary information such as
technology parameters of PVC pipe extrusion machine, technology of
extrusion process , formulation cost and operation manual . The
following information can help you find reliable PVC pipe extruding
machine manufacturer in China.
- What's the purpose of your PVC pipe used for ?
- What's the necessary machines for making PVC pipes and what's the
machines used for?
- How to make PVC pipes by necessary PVC pipe extrusion machines ?
- How to find one reliable PVC pipe machines manufacturer or
- Magstar Machinery makes PVC pipe extrusion machine line in China
1. What's the purpose of your PVC pipe used for ?
If you have a plan and want to buy PVC pipe extrusion machine,
first of all, you should tell your PVC pipe extrusion machine
supplier what's the kind of PVC pipe you would like to make.
The following main types of PVC pipes are based on material used:
- UPVC pipe: The most commonly kind PVC pipes we see and find on the market,
which is used for drainage, sewage and conduit .
- CPVC pipe: It is also named chlorinated PVC becuase the pertcentage of
chlorine is more higher than PVC. It is a problem free,long lasting
solution for harshest industrial environments.
- OPVC pipe: It has many specification areas as it is oriented
polyvinylchloride which is alsoin use for sewage systerms as well
at water distribution areas. These pipes are almost 35% lighter
than general PVC pipe and quite the same performance.
- MPVC pipe: It is fundamentally a thermoplastic alloy with additions of
modified agents to increase the physical properties like ductility
and toughness. It is main used in high pressure industrial
applications, irrrigations and water purification.
- Plain PVC pipe: The cheapest of all the PVC pipe material, and it is easy to find
Most customers are looking for plain pipe PVC pipe or UPVC pipe
extrusion machine line due to raw material and PVC pipe making
machine cost is lower.
The following two types of PVC pipes are based on material
- Rigid PVC pipe : Rigid PVC material is a kind of powder material which is used for
hard PVC pipes. It is main used for water supply and drain, as well
as electric conduit pipe when pipe is smaller with different kinds
- Soft PVC pipe : Soft PVC material is a kind of granule material which is used for
making soft PVC pipes. It is main used for garden hose pipe and
suction hose pipe, as well as PVC firber hose pipe with different
kinds of extrusion moulds.
Most customers are looking for rigid PVC pipe extrusion machine
line due to its large using applicances. But in recent years, soft
PVC pipe extrusion machine line is more and more popular too.
The following main three types of PVC pipes are based on functions
of PVC pipes used:
- Electric conduit PVC pipe: It is used to conduit electric wires in houses, apartments,
factories or any construction buildings. The main function is
protect electric wires, anti-fire and easy to maintenance.
- Water supply PVC pipe: It is used to supply pressure water for life,agriculture or
industry using purposes with ISO, BS, AMS or GB standard wall
thickness. In normal, calcium carbonate is no more than 25%.
- Water drain PVC pipe: It is used to drain non-pressure water for life , agriculture or
industry using purposes with thin wall thickness. The main function
is drain non-pressure water, such as industry wasted water, rain
water drop on the buildings, life wasted water . In normal, calcium
carbonate is higher than 60%, sometimes, it can be reach to 150%.
Most customers are looking for the above three kinds of PVC pipe
making machine. In normal, customers would like to buy one machine
which can make all the above three kinds of PVC pipes. But in
strictly to say, this is not right and science mission. Due to
design of screw and extrusion moulds and using life of screw and
barrel, we always suggest customers choosing one customized PVC
pipe extrusion machine for making one kind PVC pipe only.
2. What's the necessary machines for making PVC pipes and what's
these machines used for?
A standard PVC pipe manufacturing plant factory should be including
the following necessary machines for making PVC pipes .
- PVC material hot and cold mixer unit machine
PVC powder hot and cold mixing unit machine is main used in PVC
powder resin adding, drying, coloring and mixing with different
processing aids according to different fomulas for different PVC
pipe using function purpose.
PVC powder hot and cold mixing unit machine is composed of high
speed hot mixer, cool mixer and control cabinet.
Hot mixer : Heating and stiring PVC resin powder by self-friction due to
blades is on high speed rotating by motor, as well as heater inside
of the pot.
Cool mixer : Cooling PVC resin powder by circuit cooling water of the bending
stainless steel pipes for touching material in the pot.
Screw loader machine is used for loading mixed PVC resin material
into hopper on the top of extruder from ground. Mixed PVC resin
material will be transported by screw covery in the middle of
stainless steel pipe automaticly. It is controlled by timer, motor
will start to working and driven the screw transport the mixed PVC
resin material forward every setting minutes.
- Conic Double Screw Extruder
Conic double screw extruder is most impoart part of PVC pipe making
machine line. It is used for feeding,transporting,
plasticing,melting mixed PVC resin material.
Conic double screw extruder is composed of driven motor, gear
reducer box, screw and barrel, feeder, casting aluminum heater,
cooling blower, vacuum pump, hopper and control cabinet.
Driven motor: It is main part of PVC pipe conic double screw extruder. We'd
better choose good brand AC type driven motor matching with
inverter controll for saving power running cost.
Gear recuder box: It is used for connecting motor and screw . As we know that motor
rotating speed is very high , if we connnect motor and screw
directly, screw rotating speed will be too fast, mixed PVC resin
material will be not melting and plasticing inside of barrel. So we
choose gear reducer box for connecting motor and screw for reducing
rotating speed of screw through size and teeth of gear changing in
the gear box.
Screw and barrel: It is most important part of conic double screw extruder. Quality
of PVC pipes main depends on this part. In normal, the surface of
screw should be paint double alloy for anti-wear due to mixed PVC
resin material including high percent of calcium carbonates. At the
same time, the design of screw structure is a key point for
extrusion capacity and quality, now design of screw is becoming
standardization and homogenization on the market, quality of screws
are stable for most suppliers now.
Feeder: It is used for feeding mixed PVC resin material into barrel from
the hopper on the top of extruder. This device is developing from
single screw feeding to parallel screw feeding process. Now more
and more PVC pipe making machine manufacturers adopt parallel screw
feeding device for avoding mixed PVC resin crack-bridging while
material transported into barrel on the bottom of hopper.
Casting aluminum heater: It is used for heating barrel and screw which ensure mixed PVC
resin material can be plasticizing and melting under the suitable
temperature when mixed PVC resin material comes into inside of
barrel and transported forward by screw.
Cooling blower : It is used for cooling barrel and screw. Due to casiting aluminum
heater is keeping heating, temperature of screw and barrel will be
increasing and if it excess setting temperature, cooling blowers
will be started to work for cooling barrel which avoid PVC material
resolved in the inside of barrel due to temperature is too high.
Vaccum pump : It is used for sucking the moisture of the mixed PVC resin
material which is under suitable temperature from the barrel in
order to make sure getting the final PVC pipes better quality.
Hopper : It is used for keep the mixed PVC resin material in the silo and
make sure material can be into barrel continuously. It is like a
material transport station.
Control Cabinet: It is used for control whole cornic double screw extruder running
by switchs or PLC programes according to different circuits control
- Extrusion Mould & Die Head
Extrusion mould and die haed is another important part of PVC pipe
production line. Mixed PVC resin material will be forced into
extrusion die through connect flange by screw forward transported
after plasticizing and melting in the inner side of barrel.
Due to extrusion mould and die head are under heatting too and it
is still on fluid status after plasticizing and melting in the
inner side of barrel on the conic double screw extruder, mixed PVC
resin material can be come out from die head easy as people
required shap,diameter and thickness.
People can make many different diameters and thickness final PVC
pipes with the same extrusion mould body by changing pins and die
heads only . It can save much cost of extrusion mould.
- Vacuum Calibrating Cooling Tank
Vaccum calibrating cooling tank is main used for cooling hot PVC
pipes which is from extrusion mould die. It consists of tank body,
vacuum pump, water pump, water spray nozzles system, temperature of
water control system.
Tank boady is made by stainless steel because of there is water inside of
tank and it is should be anti-rust. Length of tank is must be
enough to cooling down the temperature PVC pipes when PVC pipe come
out from tank. Length of tank is 6 meters or 9 meters according to
diameter and thickness of PVC pipes.
Vacuum pump is used for sucking the air from the closet cooling tank, which
can keep shape of PVC pipes is round and surface of PVC pipes is
smooth and shine.
Water pump is used for supply cooling water continuously for cooling PVC
pipes and make sure that temperature of PVC pipe is down.
Water spray system is used for transpoting cold water from water pump to each
stainless steel water pipes and spraying cold water on the surface
of PVC pipes for reduce the temperature of PVC pipes through the
many spray nozzles which are connecting the holes on the stainless
steel water pipes that around the inner side of tank.
Temperature of water control system is used for changing circuit water in time. As we know, after
running some time, the temperature of water in the tank will be
rising due to cold water take the heat quantity from hot PVC pipes
and cooling efficiency will be down. So control system will start
to drain the hot water from tank body and supply new cold water
into tank body automaticly when temperature of water reach to
setting temperature value.
- Haul-off Unit Machine/ Traction Machine
Haul-off unit machine/ traction machine is main used for clamping
and pulling the PVC pipe forward a long length at a constant speed
through rubber pad which located on each pedrail.
It consits of driving motor, pedrail/ pulling belt, air cylinder,
rubber pad. According to PVC pipe diameter range, haul-off unit
machine will be equipped 2, 3, 4, 6, 8 or 10 pedrails/pulling belts
for make sure traction force is enough to pull PVC pipe forward.
Pedrails/pulling belts are located under the extrusion axis, which
are mechanically adjustable and upper ones are driven by
Special silicon rubber pad on each pedrail/pulling belt is soft and
anti-wear, which make sure pedrails do not damage PVC pipes and
there is no marks on the surface of PVC pipes.
Cutter machine is used for cutting PVC pipes automaticly by PLC
controller according to setting length. Working principle is that
there are clamps which controlled by air cylinder for clamping PVC
pipes first, then blades which on one movable plate start to
cutting PVC pipe, meanwhile movable plate be start to moving
forward along the guide rail and keep the same speed with extrusion
line speed , because PVC pipe is continuous extruding and not
According to diameter range of PVC pipes, there are chip-free type
cutter, guillotine type cutter and planetary type cutter as
options. Each type cutter with it's special features for ensure it
is right type for some PVC pipe diameter ranges.
Planetary cutter is delivered as a single cut unit and used for
cutting PVC pipes outdiameter over 110mm with chamfer function. It
consits of oil pump station, driving motor, rotary bearing,clamps,
blower, air cylinder ,guide rail and moveable plate. Oil pump is
used for offer enough pressure to ensure push blade touch the
around surface of pipes . There are two driving motors on this
machine, one motor is used for cutting and chamfer function,
another motor is used for driving rotary bearing for keeping blade
Stacker is used for stock final PVC pipes according to it's
diameter range. It consits of air cylinder, wheel and steel frame.
