What to do if the sound is too loud during PC extrusion production

The automatic extruder is an important equipment for plastic molding and granulation. The normal use of the extruder can give full play to the performance of the machine and maintain a good working condition. It is necessary to persist in careful maintenance to extend the service life of the machine. So how to deal with the abnormal noise of the automatic extruder?

1. If it occurs in the reducer, it may be caused by bearing damage or poor lubrication, or it may be caused by gear wear, improper installation and adjustment, or poor meshing. It can be solved by replacing bearings, improving lubrication, replacing gears or adjusting gear meshing conditions.

2. If the noise is a sharp scratching sound, consider the possibility that the shaft head and the drive bushing may be scratched due to the deviation of the barrel position. It can be solved by adjusting the barrel.

3. If the barrel makes noise, it may be that the screw of the automatic extruder is bent and sweeps or the set temperature is too low to cause excessive friction of solid particles. It can be handled by straightening the screw or increasing the set temperature.
