Working Principle of Single Screw Extruder Machine
Ⅰ. Introduction of single screw extruder machine

As a common extruder equipment, single screw extruder machine is used in the plastics processing industry. What is the principle and structure? The following is an analysis of the working principle of single screw extruder from the conveying section, compression section, and metering section of the extruder.

The single screw plastic extruder net machine is generally divided into three sections in terms of effective length. The effective lengths of the three sections are determined according to the screw diameter, pitch, and screw depth, which are generally divided into one-third of each.

Ⅱ. Working principle of single screw extruder

1. The last thread of the material opening starts to be called the conveying section.

The material here is not required to be plasticized, but it must be preheated and compacted. In the past, the old extrusion theory believed that the material here was loose. Later, it was proved that the material here is actually a solid plug, which means that the material is a solid like a plug after being squeezed, so its function is to complete the delivery task.

2. The second section is called the compression section

At this time, the volume of the screw groove gradually becomes smaller, and the temperature must reach the degree of plasticization of the material. The compression produced here is from the third conveying section, and the compression is here to one. This is called the compression ratio of the screw - 3:1. There are also changes for other machines. The plasticized material enters the third stage.

3. The third section is the measurement section

The material here maintains the plasticizing temperature, just like a metering pump to accurately and quantitatively transport the melt material to supply the machine head. At this time, the temperature cannot be lower than the plasticizing temperature, generally slightly higher.

The single screw extruder machine is mainly used for extruding soft and hard polyvinyl chloride, polyethylene and other thermoplastic plastics. It can process a variety of plastic products, such as films, tubes, and plates, in conjunction with corresponding auxiliary machines (including molding heads), and it can also process the granulation.

As one of plastic pipe production line manufacturers, we will do our best to meet all the needs of customers.

Plastic or Metal Die Extrusion Molding(2022年10月31日)

Plastic or Metal Die Extrusion Molding
Extrusion molding is to mold plastic or metal into the predetermined shape. During this process, the metal or plastic melts and then they are pushed through the mold to form a linear shape. The final shape, usually called a rod, although not necessarily cylindrical, is then cooled and then cut into various lengths according to the application.

If you cut a rod of material into thin slices, the plastic extrusion shapes are called cross-section. The shape of the extrusion molding machine is the same as the shape of this cross-section. It is uniform throughout the project until the material or mold is changed.

The size of the extrusion molding machine is different, but it is usually at least the size of a car. It is equipped with some methods of inserting the material into the machine and melting it into a liquid state, which can be pushed through the mold to form its shape then. As a professional extrusion line manufacturer, Kailite can produce high-quality extrusion molding machines for the market.

What is the Difference between Extrusion and Injection Molding?
The components used for plastic and metal extrusion molding are similar in function but different in operation. For plastic extrusion molding, a large funnel (called a hopper) is placed on the top of the machine. Pour small particles of material, such as high-density polyethylene or plastic. These particles melt into a liquid state easily and are pushed through a mold to form a plastic tube or rod of a certain shape. For metal extrusion molding, a preheated heavy metal rod called a blank is inserted into the machine and then pressurized to force it through a die to make a metal tube or rod.

Like the injection molding, there are many variables to consider when extruding the materials. The temperature of the material, the pressure the material is forced through the die, and the time it takes to extrude are all factors that can be adjusted to create the ideal material condition. Extrusion molding is similar to injection molding in that it melts plastic or metal materials and then forms them into a predetermined shape. However, through injection molding, plastic or metal will not be continuously extruded. When the mold or mold filling material is cooled, open the pre-formed shape and then put them into the container.

When designing the mold for the extrusion line machine, the factors affecting the cooling of the finished material must be considered. For example, the shrinkage of plastics and metals is the percentage of the size that the material loses after cooling. When designing a mold, the shrinkage of various materials must be considered.

Function Introduction of Plastic Pipe Production Line Equipment(2022年10月31日)

kailitemachinery — 2022-10-31T18:34:31+0900

https://www.kailitemachinery.com/function-introduction-of-plastic-pipe-production-line-equipment.html

Function Introduction of Plastic Pipe Production Line Equipment
The plastic pipe machinery mainly has seven functions, as follows:

1. Raw material mixing for plastic pipe production line

Add PVC firming agent, plasticizer, antioxidant and other auxiliary materials into the high-speed mixer according to the proportion and process, and the material is heated to the set process temperature through the self-friction of the material and the machine. Then the material is reduced to 40-50°C by the cold mixer; in this way, it may be added to the hopper of the extruder.

2. Part of the extruder of the plastic pipe production line

This plastic extruder net machine is equipped with a quantitative feeding device, so that the extrusion volume can be matched with the feeding volume, and the product can be extruded firmly.

Because of the characteristics of the conical screw, the feeding section has a larger diameter, and the heat transfer area and shear speed of the material are relatively large, which is beneficial to the plasticization of the material. The small diameter of the screw in the metering section reduces the heat transfer area and the shear speed to the melt, so that the melt can be extruded at a lower temperature. When the screw rotates in the barrel, it plasticizes the PVC mixture and pushes it toward the machine head, so as to achieve compaction, melting, mixing and homogenization; and to achieve the goals of exhaust and dehydration. The feeding device and screw drive device of the plastic pipe production line adopt frequency conversion speed regulation, which can realize synchronous speed regulation.

3. Part of the extrusion die head of the plastic pipe production line

After compacting, melting, mixing and homogenizing the PVC, the subsequent materials are pushed to the die by the screw. The extrusion die is the key part of the pipe forming.

4. The vacuum shaping water tank of the plastic pipe production line

It is used for the shaping and cooling of pipes. The vacuum shaping water tank is equipped with a vacuum system for shaping and cooling and a water cycle system, a stainless steel box, and cycle water spray cooling. The vacuum shaping water tank is equipped with a front and rear moving device and a manual device for adjusting left and right and height.

5. Traction machine of plastic pipe production line

It is used to continuously and actively lead the pipes of the cooled and hardened pipe production line from the machine head, and the frequency conversion speed is adjusted.

6. Cutting machine for plastic pipe production line

After being controlled by the travel switch according to the requested length, active cutting is carried out, and the frame turning is delayed to perform flow production. The cutting machine uses the fixed-length work switch signal as a command to realize the whole cutting process. During the cutting process, it is synchronized with the pipe operation of the PVC pipe extrusion line. The cutting process is realized by electric and pneumatic drive. The cutting machine is equipped with a dust collector to cut Debris is sucked out in time and recycled.

7. The turning frame of the plastic pipe production line

The turning action is realized by the pneumatic control by the cylinder, and the turning frame is equipped with a limit device. When the pipe is cut by the cutting saw, the pipe of the plastic pipe production line is continuously transported. After a delay, the cylinder enters the work to realize the turning action and reach the discharge target. After unloading, it will automatically reset after a few seconds delay and wait for the next round.

Definition and Operation of Single Screw Extruders(2022年10月31日)

Definition and Operation of Single Screw Extruders
1. Single Screw Extruder Definition
Screw extruders are divided into single screw extruders and multi-screw extruders. The single screw extruder is the most important type of extruder in the polymer industry. Its main advantages are low cost, simple design, powerful and reliable function, and satisfactory cost performance. The screw of a conventional plasticizing extruder has 3 different geometric cross sections.

This geometry is also called "single stage". "Single-stage" means that although the screw has 3 different geometric cross-sections, there is actually only one compressed cross-section. The first part (closest to the feed port) has a relatively deep groove. Most of the materials in this section are solid. This part is called the feed part of the screw. The groove in the last part (closest to the mold) is usually shallow. Most of the materials in this part are in a molten state. This screw part is called the metering part or the extruding part. The second part connects the feeding part and the metering part. This part is called the transition part or the compression part. In most cases, the depth of the screw groove (or the height of the screw edge) decreases linearly from the feeding part to the metering part, so the material is compressed in the screw groove. In the future, it will prove that this kind of compression is essential for the correct operation of the extruder in the quietest conditions.

2. Basic operation of single screw extruders
The operation of the single screw extruders is very simple. The material enters from the hopper. Usually, the material flows from the hopper into the extruder barrel by gravity. Some materials are not easy to flow in the dry state, and special measures must be taken to prevent the materials from hanging in the hopper. Once the material falls into the extruder, the material is located in the annular space between the single extruder screw and barrel of the extruder, and then is surrounded by the drive of the spiral ribs and the grooves of the wing. When the screw rotates, the machine stands still. Therefore, the friction force acts on the material and surface of the screw. At least the object is in a solid state (below the melting point), and these friction forces are responsible for transporting the material forward.

When the material moves forward, the material will be heated by the heat generated by friction and the heat generated by the barrel heater. When the temperature of the material exceeds its melting point, a molten film is formed on the inner surface of the barrel, and the plasticized part starts. It must be pointed out that the starting point of the plasticizing section is usually not the starting point of the compression section. The dividing line of each functional segment depends on the properties of the polymer, the geometry of the extruder and the operating conditions. Therefore, the dividing line can be changed according to changes in operating conditions. However, the geometric cross-section of the screw is determined by the design and will not change due to changes in operating conditions. When the material moves forward, the amount of solid material at each location decreases due to melting. When all the solid polymer disappears, it reaches the end of the plasticizing section and the melt conveying section begins. In the solid conveying zone, the melt is uniformly conveyed to the mold.

When the polymer flows into the mold, it assumes the shape of the mold runner. Therefore, when the polymer leaves the mold, its shape is more or less consistent with the cross-sectional shape of the last part of the mold runner. Since the mold generates flow resistance, pressure is required to force the material through the mold. This pressure is commonly referred to as mold pressure. The pressure of the mold depends on the shape of the mold (especially the runner), the temperature of the polymer melt, the flow rate through the mold, and the rheology of the polymer melt. The die pressure is generated by the die, not by the extruder. The extruder only generates enough pressure to force the material through the die. If the polymer, extrusion volume, die and die temperature are the same, there will be no difference whether the extruder is a gear pump single-screw extruder or a twin-screw extruder, and the pressure head force is the same. Therefore, mold pressure is caused.

Basic Working Principle of Plastic Extruder(2022年10月31日)

https://www.kailitemachinery.com/basic-working-principle-of-plastic-extruder.html

Basic Working Principle of Plastic Extruder
The production line of the plastic stick extrusion machine is composed of the extruder (the main body of the machine), die (head), product forming, and collection machinery (auxiliary machine).

How does an extruder machine work, what is plastic extruder machine and what is its working principle?
The working principle of the pvc plastic extruder in the process of producing plastic products is as follows. It is necessary to select an extruder production line suitable for the variety of raw materials and product specifications. Through the adjustment and control of parameters such as temperature (heating and cooling), pressure, and speed, the process of continuous extrusion of plastic products on the extruder production line is achieved.

The extruder machine process of plastic (eg. the plastic pipe extrusion line) relies on the screw of the extruder to convey, compact, and further melt the plastic, so that the plastic is in a completely uniform plasticized state. Then it is extruded through a die under pressure and then shaped by the molding machine. After cooling, the required products are made. Therefore, the plastic extruder net machine is the key equipment for plastic extrusion, which determines the quality and output of extruded products.

The plastic extruder is mainly composed of the screw, the barrel, the heating and cooling system, transmission system, and control system, among which, the screw is the most critical functional part of the extruder, for the screw is responsible for the main functions of the extrusion process such as conveying, compacting, plasticizing, homogenizing, pressurizing, and pumping the material. A typical single-screw extruder screw is the three-stage including the feeding section, the compression section, and the extrusion section (or the homogenization section). The most important parameters of a extruder screw include the screw diameter D, screw length to diameter ratio L/D and compression ratio.

Application of Single Screw Extruder in Pipe Production(2022年10月31日)

kailitemachinery — 2022-10-31T18:33:22+0900

https://www.kailitemachinery.com/application-of-single-screw-extruder-in-pipe-production.html

Application of Single Screw Extruder in Pipe Production
The traditional single-screw extruder design is mostly three-stage, and its main function is to plasticize, homogenize, and continuously press and send granular or powdered plastic to the extruder head. The plastic undergoes different physical state changes during the extrusion process, but no chemical reaction occurs.

Ⅰ. The main defects of single screw pvc pipe machine process

In the process of the silane cross-linked polyethylene pipe extrusion line, the raw material undergoes the above physical process in the extruder, but also completes the polyethylene-silane grafting reaction. The traditional three-stage single-screw extruder process obviously cannot be fully adapted The main drawbacks of reactive extrusion molding requirements are that the residence time distribution of the materials is too wide and the relatively short length of the complete melting zone of the materials. At the same time, there are also problems such as low conveying efficiency of the solid-liquid mixed system by the solid conveying section.

Ⅱ. The specific requirements of single screw extruder process reaction extrusion

1. Raw material drying system

The single-screw extruder process requires that the water content of the resin is not greater than 200mg/kg. If the drying requirements cannot be met with only an ordinary hopper dryer, for this reason, a raw material drying system with air dehumidification device should be equipped.

2. Metering and feeding system

The single-screw extruder process is equipped with an advanced weighing and feeding system. The solid and liquid are measured separately. The proportion is controlled by a computer, and the accuracy can reach 0.25%.

Since vinyl silane can easily absorb moisture in the air and turn it into silanol, the metering and feeding system has adopted strict moisture-proof measures. At the same time, the flash point of vinyl silane is low, the metering pump should be equipped with an explosion-proof motor, and the equipment and containers in contact with the silane must have a reliable ground to prevent electrostatic sparks from detonating the silane.

3. Plasticized extrusion parts

As mentioned above, the single-screw extruder process not only plasticizes the plastic, but also ensures the smooth grafting of polyethylene and silane. Therefore, the basic principles for designing the screw of the single-screw extruder are:

① There must be a sufficiently long feeding section;

②The screw runner should avoid dead corners, and at the same time improve the surface finish of the screw and barrel to prevent the accumulation of reaction materials and shorten the continuous operation cycle of the extruder;

③The groove depth of the screw metering section should not be too shallow to avoid excessive shearing of the graft body;

④The screw length to diameter ratio can be appropriately longer;

⑤ Properly extend the residence time of the melt in the extruder, and make the residence time of the melt as uniform as possible.

However, theoretical and experimental studies have shown that simply increasing the length of the screw cannot effectively improve the efficiency of the grafting reaction. At present, a four-stage single-screw extruder, through actual production and operation, has proved that it can significantly improve the efficiency of silane grafting reaction and increase the output of a single machine.

Analyzing and Troubleshooting Single Screw Extruders(2022年10月31日)

Analyzing and Troubleshooting Single Screw Extruders
Single-screw extruder is a common mechanical equipment in rubber and plastic manufacturers. The screw is the main part of the single-screw extruder. The quality of the two parts of the single-screw extruder, the screw and the barrel, plasticize the material. The quality of products and production efficiency have an important influence.

Single-screw extruder screws will wear out for some reasons, leading to quality deviations in the production of rubber and plastic equipment, so what are the main faults of the single screw extruder machine?

Analyzing and troubleshooting single screw extruders

The first type: When the screw of the single-screw extruder rotates in the barrel, the friction between the material and the two will gradually wear the working surface of the screw and the barrel. The diameter of the screw gradually decreases, and the diameter of the inner hole of the barrel gradually increases. In this way, the matching diameter gap between the screw and the barrel increases a little as the two gradually wear.

Since the resistance of the head and the splitter plate in front of the barrel has not changed, this increases the residual amount of the extruded material when it advances, that is, the amount of material flowing from the diameter gap to the feeding direction increases. As a result, the output of the single screw plastic extruder decreased. This phenomenon increases the residence time of the material in the barrel and causes the material to decompose. If it is polyethylene, the hydrogen chloride produced by the decomposition deepens the corrosion of the screw and the barrel.

The second type: Because the material is not uniformly plasticized, or metal foreign matter is mixed into the material, the torque of the single-screw extruder line screw is suddenly increased. This torque exceeds the strength limit of the screw, causing the screw to twist and break.

The third type: If there are fillers such as calcium carbonate and glass fiber in the material, it will accelerate the wear of the screw and barrel of the single-screw extruder.

FAQs of Plastic Extrusion Machinery
Q
What is an extrusion machine?

A.
Extrusion machines force or pull unformed material into alignment guides and shaped dies to produce lengths of stock forms and cross-sectional shapes. Plastic extrusion machinery is used mainly in the plastics, metals, and composite-forming industries. Extrusion machines are also used in automotive, aerospace, and construction applications.

Q
What is extrusion process in plastics?

A.
Extrusion is a continuous process of converting a solid plastic mass, pellet or powder into a melted form where it is pushed through a die into a shape. This shape is then moved through various secondary operations where it is cooled then cut, coiled or experiences a variety of other possible operations.

Q
What kind of plastic is best for extrusion or molding?

A.
Commodity plastics are suitable for most applications and account for 90% of all thermoplastic use. They are readily available, easy to process, and the least expensive plastic for extruded products. Examples of commodity plastics include polypropylene (PP), polyethylene (PE), and polyvinyl chloride (PVC).

Q
What is extrusion process?

A.
Extrusion is a process used to create objects of a fixed cross-sectional profile. A material is pushed through a die of the desired cross-section. The extrusion process can be done with the material hot or cold. Commonly extruded materials include metals, polymers, ceramics, concrete, modelling clay, and foodstuffs.

Q
What is the difference between extrusion and injection molding?

A.
Injection moulding forms three-dimensional shapes. The injection moulding process is based on the molten die-casting method. In the extrusion method, the finished products have a two-dimensional form which is continuous in length and can be cut to multiple lengths and punched or notched.

Working Principle of Single Screw Extruder?
Here are five steps introducing the single screw extruder machine working principle:
Step 1: feed resin or pellets
The polymer, as a powder or granule, is continuously fed into the extruder barrel from the hopper.

Step 2: Resin melting
The heated barrel melts the polymer and transports the material through the mold.

Step 3: The actual extrusion process
The screw channel exerts force on the polymer through the rotating screw, while the stationary barrel exerts a destructive force on the rotating polymer and causes the polymer to slide slightly on the surface of the screw.

Step 4: Cooling
After passing through the mold, your plastic will pass through the cooling zone.

Step 5: Final finishing process
It involves finishing touches to your plastic. This includes drilling, printing, bending or cutting.
