When the screw groove is found to be blocked, do not stop the machine immediately. Instead, run it for a while after stopping feeding until there is a burnt smell before stopping the machine. This can prevent the mould head and screw from biting. If the mould head and screw bite and cannot be removed, do not forcefully knock and smash them. You can remove them from the body and let them burn in the fire for a while before they can be removed.

With the continuous development of the extruder, the production performance is continuously improved, the work quality is reliable, the failure rate is low, the operation and maintenance are convenient, and the economic benefits of the enterprise are effectively improved; In the continuous research, the production process of the extruder has been improved to make it have better operation methods and greatly improve the production efficiency; In the manufacturing process, the main components of the extruder are made of special alloy materials and heat treated, which have a good service life; The expansion machine adopts dry expansion process and self-heating method, which is more in line with the actual needs of users; The main parts of screw extruder have powerful self-cleaning function, reduce manual operation, and save a lot of labor costs for extruder enterprises.
