High-Speed Twin-Screw Extrusion Systems Factory

How to optimize the high-speed twin-screw extrusion to improve production efficiency and product quality when processing high-viscosity and high-filling rate materials?
Screw design optimization: At the same screw speed, increasing the depth of the screw groove can greatly increase the conveying volume, which is especially important for high-filling rate materials. At the same time, in the feeding section and the devolatilization section, increasing the free volume of the screw element can improve the processing capacity of the extrusion, ensure that the material fully fills the screw groove, reduce dead corners, and improve mixing efficiency. At high screw speeds, although the residence time of the material in the extrusion is reduced, appropriately increasing the screw length can extend the plasticizing, melting and mixing time of the material to ensure that the material is fully mixed and plasticized. At the same time, high speed can speed up material flow and improve production efficiency. The screw and barrel are designed as a building block combination structure, and different screw element geometric parameters are selected according to the function of each section to optimize the mixing and plasticizing effect.
Control system optimization: Equipped with an advanced temperature control system, the heating area is precisely adjusted to ensure that the temperature of the plastic is uniform and stable during the melting process, avoiding quality problems caused by temperature fluctuations. Adopt an automated control system to realize the automatic start and stop, speed adjustment, temperature control and other functions of the equipment, reduce manual intervention, and improve production stability and efficiency.
Optimization of exhaust performance: In the process of high-speed twin-screw extrusions processing high-viscosity and high-filling rate materials, the optimization of the exhaust system is crucial. Such materials often contain more volatiles, moisture or air. If the exhaust is not smooth, these gases will form bubbles in the molten material, seriously affecting the density and final performance of the product. Therefore, we optimize the exhaust system to ensure that the gas in the molten material is effectively removed, reduce the generation of bubbles, and improve the density and performance of the product.
Optimization of materials and process parameters: Since the screw and barrel need to withstand greater torque and wear when processing high-viscosity and high-filling rate materials, high-strength and wear-resistant materials such as alloy steel are required. According to the characteristics of the material and production requirements, adjust the process parameters such as screw speed, temperature, pressure, etc. to achieve the best mixing and plasticizing effect.
Equipment maintenance and maintenance: Regularly clean the residual materials and impurities inside the screw and barrel to prevent them from affecting the fluidity and mixing effect of the material. During the cleaning process, care should be taken to protect the surface of the screw and barrel to avoid scratches or damage. Regularly check the wear of key components such as the screw, barrel, and bearings, and replace severely worn components in time to avoid equipment failure and production interruption due to component failure. The transmission system is an important part of the extrusion, and its performance directly affects the operating stability and production efficiency of the equipment. Regularly check the lubrication, gear meshing, and bearing operation of the transmission system to ensure that the transmission system is in good condition. In addition to daily maintenance, a preventive maintenance plan should be formulated based on the use of the equipment and the manufacturer's recommendations, including regular replacement of lubricating oil, inspection of the electrical system, and tightening of bolts to prevent potential failures.
Through measures such as screw design optimization, control system optimization, exhaust performance optimization, material and process parameter optimization, and equipment maintenance and maintenance, high-speed twin-screw extrusions can significantly improve production efficiency and product quality when processing high-viscosity and high-filling rate materials.
