What is a twin screw extruder?
The twin-screw extruder is developed on the basis of the single-screw extruder. Due to its wide feeding system(volumetric feeder or gravimetric feeder)good mixing and plasticizing performance, exhaust performance, polymer reaction, etc., it has been widely used in extrusion or pelletizing products.
Working principle of twin screw extruder:
- The laws of changes in the physical state of polymers in the extrusion process, the truth and laws of conveying and exhausting of solid melts, and the establishment of mathematical and physical models are used to guide the design of twin-screw extruders and the optimization of extrusion processes.
- Find out the real state of physical state change, mixing form, structure change process and the relationship between the final mixture and properties of two or more polymers and materials during extrusion.
- As a twin-screw extruder, the internal relationship between the reaction process, speed, performance and screw configuration and operating conditions during reaction molding is extruded, and a model is established to guide the reaction molding extrusion.
Advantages of twin screw extruders
1. Good self-cleaning: There is a speed difference at the meshing position between the twin screws. Under mutual friction, the occurrence of material stagnation can be reduced, and the self-cleaning properties of the co-rotating twin-screw are stronger.
2. For experimental research or mixing of thermosetting plastics with poor fluidity, in order to facilitate observation, or to clean the barrel, the twin-screw barrel can be made into a split structure.After opening the barrel, you can observe the melting, plasticizing and mixing state of the material, meanwhile,observe the wear degree of the threaded elements, the inner liner of the barrel and other components at any time, so as to carry out timely and effective replacement, and avoid product waste caused by damaged components.
3. Reduce manufacturing cost. Since the barrel and screw of the twin-screw are of modular structure, it is only need to replace the worn copper and some screw elements. Comparing with the single screw, the entire screw or barrel needs to be replaced. Maintenance costs are greatly reduced.
4. High torque, high speed. By observing the development trend of twin-screw extruders, we can see that this field is currently developing in the direction of high torque, high speed, and low energy consumption.
5. High output and high quality. Compared with the single-screw extruder, the twin-screw extruder, especially the intermeshing twin-screw extruder, performs better in the solid and melt conveying of materials. High output, high quality, high efficiency and other advantages.
Where can you find the twin screw extruder manufacturer?
Google is a powerful platform to find everything, you can use keywords on the web to search for what you need, such as: China, twin screw extruder, manufacturers and suppliers. Some of these sites also provide databases of Chinese twin and screw extruder manufacturers. So by using these websites you can easily find a suitable twin screw extruder partner according to your different needs.
This is one of the best ways to find Chinese twin-screw extruder manufacturers. Chinese manufacturers will participate in many industry-leading exhibitions with manufacturers from all over the world. At these exhibitions, you can not only appreciate the industry’s leading technology , you can also find many twin-screw extruder suppliers that can cooperate.
When you are in a city, you can ask for samples and suggestions from local distributors who have imported Chinese twin screw extruders for many years in a row, and they may also introduce you to some reliable Chinese twin screw extruder manufacturers. Or you can visit a local twin-screw extruder manufacturer and choose a Chinese twin-screw extruder partner that suits your business.
How to choose a China twin screw extruder manufacturer?
Determine your needs
You should understand your needs and requirements before choosing the best twin screw extruder manufacturer in China. For example: What is the main application of your twin screw extruder? What model do you choose? How much power twin screw extruder do you need? Answers to these questions will help you find the best Chinese twin screw extruder Machine manufacturer.
There are still some reasons for choosing Chinese twin-screw extruder manufacturers, including good product performance, high quality, energy saving, environmental protection, and convenient use and maintenance. And a good Chinese twin screw extruder manufacturer can also provide you with a series of customer services, such as custom design services, complete services of one-stop purchasing services, fast delivery time, etc.
Choose a factory with a good reputation in China. You can find the best Chinese twin screw extruder manufacturers from well-known distributors in China to local factories near you.
