Maintenance and maintenance of injection screw barrel

Por Cathy Lin September 20th, 2024 vistas 9
The maintenance and maintenance of injection screw barrel ‌ is the key to ensure the efficient and safe operation of injection molding machine. Here are some key care and maintenance measures:

‌ material matching ‌ : ensure that the material used matches the screw, especially for corrosive materials and hard materials, such as PVC, flame retardant materials, glass fiber added materials, professional screw should be used, avoid the use of ordinary screw ‌.

‌ preheating ‌ : Before the injection molding machine starts, the cylinder should be fully preheated. For different diameter of the screw, the preheating time is different, the diameter of the screw less than Φ60mm preheat 15 minutes, and the diameter of the screw greater than Φ60mm need to preheat 30 minutes ‌.

‌ temperature control ‌ : The lower limit of temperature should be avoided during production, for example, PC material should be produced at more than 250 degrees, while ABS production at more than 185 degrees will cause serious wear to the screw. At the same time, stop more than half an hour, should set heat preservation and clean the material in the cylinder ‌.

‌ Cleaning and lubrication ‌ : clean the screw surface regularly, use appropriate lubricants to reduce screw wear and extend service life. Be careful not to over-tighten the screw, so as not to deform or damage ‌.

‌ Foreign matter prevention ‌ : Avoid metal debris and debris falling into the hopper, use magnetic hopper to prevent iron filings into the barrel. Special attention should be paid to ‌ when processing recycled materials.

‌ temperature regulation ‌ : regularly check the temperature control system of the injection molding machine cylinder to ensure the stable temperature, to ensure the quality of plastic materials and the smooth injection molding process ‌.

‌ routine maintenance ‌ : pay attention to the amount, temperature and quality of hydraulic oil, keep the oil filter clean, replace the hydraulic oil regularly, and clean the cooler ‌.

Through the above measures, the service life of the injection screw barrel can be effectively extended, and the production efficiency and quality of the injection molding machine can be improved.
