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.
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:
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 characteristics used:
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:
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 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 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 required.
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.
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 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 pneumaticlly.
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 stopping.
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 around pipes.
Stacker is used for stock final PVC pipes according to it's diameter range. It consits of air cylinder, wheel and steel frame.
