PVC doors and windows making machine/PVC profile extrusion line

Description for PVC doors and windows making machine

PVC doors and windows making machine is optimized in design, referring to the newest foreign technology. The line has the advantages of stable plasticization, high output, low sheering force, long life service and other advantages. The calibration unit’s pump and haul off unit’s reducer are famous brand products. After simple changing of the die and screw, it also can produce the foam profiles.

Flow Chat for PVC doors and windows making machine:

Raw material → mixing → granulating → conical twin-screw extruder → profile extrusion mould → cool molding die → vacuum calibration support → belt haul-off → cutter → rack → finished product

PVC doors and windows making machine plastic profile extrusion line

Q: Basic parameters of extruder screw: 3, compression ratio epsilon, also known as the geometric compression ratio of screw, is the ratio of the volume of the first screw groove to the volume of the last screw groove at the homogenization section. It is determined by the physical compression ratio of plastics - that is, the density of the product and the density of the performance of the feed. The extruder is relatively compressed, the purpose is to make granular plastics fully plasticized and compacted. The selection of compression ratio should be different when different kinds of processing plastics are used. According to the compression ratio, the types of screw can be divided into three types: equidistant, unequal depth, equal depth, unequal distance, unequal depth, unequal distance. Among them, equidistant and unequal depth is the most common one. This kind of screw is easy to process, the contact area of plastic and cylinder is large, and the effect of heat transfer is good.

Q: Extrusion blow molding machine, storage or continuous type good?: This is not good or bad, depends on what your product is If the product cycle large volume high capacity is bound to produce a product with storage because of your long,

Q: Extruder price: According to the size of the screw, single and double screw configuration is different, there are many different prices between fifty thousand to two hundred thousand, we specialize in the production of extruders, crushers and mixing machines, high quality and low price, contact information on the user name

Q: Before and after the original good tune, up and down again before and after the tune, before and after, and up and down again: The nose is not accurate enough or wornOr the screws are not screwed in placeOr die inappropriate, too large

Q: Why? What is the raw material of plastics? What is the process flow of the process?.: It must be injection, you see that hole, that button, can not squeeze out.

Q: What should be paid attention to in the daily maintenance of the extruder?: Extrusion machine regular maintenance mainly has these aspectsdrive system(1) check the temperature rise of motor and oil tank, whether the bearing is overheated locally, the abnormal noise of motor and gear, oil leakage, radial circle of oil filter and spline shaft, and the contact gap with the end of screw.(2) regularly clean the oil filter and remove the dirt at the bottom of the tank, and lubricate the lubrication points regularly.(3) the new gear box has been filled with gear oil, and new oil will be replaced every 4000 hours after the operation.

Q: There is a 90 extrusion machine, used in the production of communication cables (outside the cable core is extruded with a layer of LLDPE), now is the configuration of Y2-280M-490KW167A inverter type ACS510197A + ABB), General Motors now found low speed when the current is too large, what reason? How to solve? The details are as follows: used for communication cable production HYA30*2*0.4, 1, line speed is 50 m / min, inverter display frequency 35.3HZ current: 116A; 2, line speed is 40 m / min, inverter display frequency of 28.2hz, current: 140A3, line speed is 35 m / min, the frequency converter significantly method: 157A 24.6HZ frequency current, because the product variety and technical reasons, we need to be in the frequency of 10HZ production. Now, it seems that if I reduce the speed again, the current will probably exceed the rated current. What should I do? Is the motor changed to frequency conversion motor? Or inverter? How to solve? Please heroes pointing, thank you!: Fan, water pump at low speed, torque is not enough, resulting in high current, if vector control can be ideal.

Q: The working principle of an extruder: What is the working principle of an extruder?:Screw with specific shape,Turn in a heated barrel,It will be delivered from the hopperThe plastic is pressed forward, allowing the plastics to be uniformly plasticized (i.e., melted)Through the head and different shapes of the mold, the plastic extrusionA continuous plastic layer of various shapes, extruded on the core and cable.

Q: Now I want to do it How to change the equipment, please help tell your heroes ah!Used to do PVC pinch plate, now changed to PVC threading tube: If you want to change, it is best to find the original purchase of equipment manufacturers, so that they change for you.

Q: Who knows the temperature regulation method of the extruder?Any information will do: 1, extrusion methodAccording to plasticizing methods: dry extrusion and wet extrusionPress the way: continuous extrusion and intermittent extrusion2, characteristicsContinuous production, high efficiency, simple operation, wide range of applications [Edit] paragraph extrusion molding equipment 1, the hostExtrusion system: composed of screw and barrel, it is the key part of extruder. Its function is to melt plastics, quantitative, constant pressure, constant temperature extrusion of meltDrive system: drive the screw to increase the required torque and torqueHeating and cooling system: guarantee the temperature of plastic and extrusion system in molding process2 auxiliariesIt is composed of head, setting device, cooling device, traction device, coiling device and cutting3 、 control systemIt consists of electric apparatus, instrument and actuating mechanismPurpose: to control the main and auxiliary motor, in order to meet the demands of speed and power; control main engine temperature and pressure and flow, to ensure product quality; to achieve automatic control of the extrusion unit, ensure the coordinated operation of main and auxiliary equipment. [edit this paragraph] extruder extruder overview of plastic extruder is the host, it consists of extrusion system, transmission system and the heating and cooling system.
