Guide to Buy PVC Compound Extrusion Machine Line
Some customers are new entrants in PVC compound extrusion machine, they don't know how to find good quality of PVC compound extrusion machine and reliable manufacturers or suppliers for their own business . At the same time, they are also worry about the quality of PVC compound extrusion machine and after sales service from China .
First ,all 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 compound extrusion machine, technology of extrusion process , formulation cost and operation manual . The following information can help you find reliable PVC compound extruding machine manufacturer in China.
1. What's the purpose of your PVC compound used for ?
PVC compound is used for rigid and soft applications like pipes, fittings, profiles, shoes, and cable with different colors. The granular particles was made after mixing, plastic extrusion, granulation and other process.. Products can be based on customer requirements, increase the hardness, the proportion of weather, environmental protection, matte surface, low temperature, ABS / PS, anti-rat, anti-mosquito and other special performance.Using the general extrusion machine processing.
2. How many ways of making plastic compound ?
There are two ways for making plastic compounds based on the time.
3. What's the necessary machines for making PVC compound and what's the machines used for?
A standard PVC compound manufacturing plant factory should be including the following necessary machines for making PVC compounds
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 or compound 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 compounding 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 compounding 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 pellets 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 pellets 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 pellets 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 die head is one part of PVC compounding extrusion 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 in 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 strips.
One set of blade is rotating around the surface of the extrusion die by high speed, so it make sure that all strips will be cutted in very short time in order to make sure that the length of strips are very smaller. It means strips will be cutted into compound or granules.
Blade rotating speed is controlled by inverter and it is adjustable for size of compound or granules.
After blade cutting , the PVC granules are still very hot and it is easy to sticker each other. So it needs cooling them in short time and reduce the temperature of small granules as early as possible. Due to PVC material characteristics, we adopt air fan cooling type , there are two or three air fans are blowing cooling winds to pipe systerm for cooling granules and transport granules forward to next silo.
Pipe and silo are all made by stainless steel which is contaced with PVC compound material for making sure material is not pollution.
