The screw barrel for extrusion of sections is the core component of plastic extruders. Proper maintenance is critical to extending its service life and ensuring consistent extrusion quality. Below are key measures for effective upkeep.
1. Regular inspection
During extrusion, the screw and barrel are subject to continuous friction. Regularly check for wear, cracks, or deformation. Replace damaged parts in time to prevent safety issues and production losses.
2. Cleaning and lubrication
Plastic raw materials often contain moisture or impurities that accumulate inside the barrel. Regular cleaning removes these residues and prevents processing defects. Adequate lubrication also reduces friction between the screw and barrel, improving efficiency and prolonging equipment life.
3. Control of temperature and pressure
Extrusion temperature and pressure directly affect melting and product quality. Excessive levels can cause plastic degradation or equipment damage, while insufficient levels lower efficiency. Operators should set parameters based on raw material type and profile design, and monitor them regularly.
4. Routine maintenance
Check the cooling, heating, and transmission systems to ensure stable operation. Verify that fasteners are secure and the electrical control system is responsive. Regular preventive maintenance identifies hidden issues early, ensuring long-term reliability of the screw barrel.
By implementing these practices, Intai Screw helps customers maximize the durability and performance of their screw barrels, supporting stable, efficient, and high-quality extrusion production.
