Extruder is one of the commonly used machinery in the plastic industry. In order to maintain the plastic extruder in good working condition and ensure efficient production operation, regular maintenance and cleaning work is required.
Regarding the content of maintenance and cleaning, various cleaning methods for extruder screws can be fully understood through this article!

Resin cleaning method
Polyester resin or epoxy resin is generally used for cleaning machines in new equipment. After a period of use in the cleaning machine or extruder, this method can be used when some materials remain on the screw or barrel, causing the extrusion speed to slow down and the color difference between different color varieties is significant.

Dismantling and cleaning
1. Manually add washing machine material from the feeding port until the color and color of the extruded material strip are the same as the washing machine material particles. Stop feeding, empty the material, and stop the screw rotation of the twin-screw extruder;
2. Open the screw extruder die head and start cleaning;
3. Rotate the screw of the twin-screw extruder and remove the orifice plate, discharge the residual washing material inside the barrel, and clean the orifice plate;
4. Stop rotating and pull out the screw to observe if it is clean, and manually remove any residue on the screw. Replace the screw; Add new materials to flush out the residual washing machine material inside the barrel, and stop the screw rotation;
5. Install the double screw extruder orifice plate and die head, and complete the cleaning operation of the double screw extruder.

Fire roasting method
Using fire or grilling to remove the plastic fixed on the screw is a common and effective method in plastic processing units. Immediately after the screw is used, a spray lamp is used for cleaning. Due to the heat generated during processing, the heat distribution of the screw is still uniform.
