How to maintain and upkeep Screw barrel for extrusion of sections to extend their service life and ensure extrusion quality?

Screw barrel for extrusion of sections, as the core component of plastic extruders, its maintenance and upkeep are of great significance for extending equipment service life and ensuring extrusion quality. Here are some key maintenance and upkeep measures:

Regularly inspect the wear of the screw barrel. Due to the constant friction and wear of the screw and barrel during the extrusion process, it is essential to regularly check their degree of wear. Once severe wear or defects such as cracks are found, relevant components should be replaced in a timely manner to avoid affecting extrusion quality and equipment safety.

Keep the screw barrel clean and lubricated. During the extrusion process, plastic raw materials may contain impurities or moisture, which can easily accumulate in the screw barrel and affect the extrusion effect. Therefore, it is necessary to regularly clean the impurities and residues inside the screw barrel. Meanwhile, proper lubrication can also reduce friction and wear between the screw and the barrel, improving the operational efficiency and service life of the equipment.

In addition, reasonable control of extrusion temperature and pressure is also an important aspect of maintaining and servicing the screw barrel. Extrusion temperature and pressure are one of the key factors affecting the melting and extrusion effect of plastics. If the temperature or pressure is too high, it is easy to cause plastic degradation or equipment damage; If the temperature is too low or the pressure is insufficient, it will affect the quality and production efficiency of the extruded product. Therefore, consumers should set the extrusion temperature and pressure parameters reasonably according to the type of plastic and profile requirements, and regularly check and adjust these parameters to ensure that they are in the best condition.

Finally, regular maintenance and upkeep of the screw barrel are also essential. This includes checking whether the cooling system, heating system, transmission system and other components are operating normally; Check whether each connecting part is securely fastened; Check whether the electrical control system is sensitive and reliable. Regular maintenance and upkeep can promptly identify and solve potential problems, ensuring the stable operation and long-term service life of the screw barrel.
