The double screw extruder is a molding processing equipment that is suitable for polymer processing with high productivity, wide application range and strong change ability. Because of its superior cost performance, it is widely welcomed by plastic product processing and manufacturing enterprises, who are searching for and selling good double screw extruders in a wide range. Now let's briefly analyze the similarities and differences between the more commonly used double screw extruders and single screw extruders:
There are significant differences in the structure of twin screw extruders and single screw extruders. The twin screw extruder has two parallel screws, which makes it better than the single screw extruder in mixing effect, because the interaction of the two screws can achieve a more uniform mixing of materials. The single screw extruder has only one screw, which mainly relies on the rotation of the screw to push the material forward, and is suitable for processing low-viscosity materials. The twin screw extruder achieves more stable material transportation through the meshing of the two screws, and can handle a wider range of materials, including high-viscosity and heat-sensitive materials. Choosing the right twin screw extruder supplier can ensure the quality of the equipment and after-sales service, thereby improving production efficiency.
The double screw extruder and the single screw extruder are different because the structure of the former one is more complicated, so the objects suitable for operation are also obviously different. The single screw extruder is mainly suitable for plasticizing and extruding polymers, especially suitable for processing granular products; while the double screw extruder is more suitable for powder processing, which can mix and plasticize the pulverized mixed PVC materials.
The difference between double screw extruder and single screw extruder is also reflected in the process control effect. The single screw extruder is mainly for pellets after granulation, and the process control operation is simple; while the double screw extruder is mainly for the mixed PVC material, and its efficient mixing and plasticizing ability can promote the rapid production of materials in batches. In addition, this lab extruder for sale does not have a material preparation process but has an additional waste grinding process, so its process control is relatively more complicated.
According to a large number of sales statistics, it is shown that the double screw extruders has gradually replaced single screw extruders and has become the mainstream trend. Many subscribers also give priority to asking for the price of stable-quality double screw extruders. The difference between the twin screw machine and the single screw machine is not only manifested in different structures, different process controls, and different suitable objects, but also in different production efficiencies and different cost inputs.
