Experts from the twin-screw extruder service provider Nanjing Jieente Electromechanical Co., Ltd. said that the plastic pellets enter the barrel through the hopper at one end of the barrel and then pass through the screw to the other end of the barrel. In order to have sufficient pressure, the depth of the thread on the screw decreases as the distance to the hopper increases. External heating and internal heat generated by the plastic and screw due to friction soften and melt the plastic.
Experts in the twin-screw service provider Nanjing Jieente Electromechanical Co., Ltd. In China, large-scale equipment has long relied on imports, and research on the localization of large-scale twin-screw granulators is underway. Precision can increase the gold content of the product, such as multi-layer composite co-extruded film. As an important means to achieve precision extrusion, the melt gear pump should be intensively developed and researched.
1, must be operated by a special person, usually the operator should learn more relevant knowledge, so that the operation will be skilled in single-screw extruder.
2, the extruder equipment must be inspected before starting the machine to see if the environment around the machine is clean, three-phase power is not in place, look at the materials are ready, and so on.
3. When the extruder is turned on, be sure to test the car. Do not add materials first. Test the car for a few minutes. Listen to see if there is any abnormal noise. If there is any odor, if the voltage, speed and sound are normal, you can just add the material to work normally.
4. When the twin-screw extruder equipment is running, it must check the running state of the extruder, especially the water temperature. If there is any abnormality, it should be treated in time.
