Common causes of screw breakage in injection molding machines

Six common reasons for screw breakage in injection molding machines:
1. The quality of the injection molding machine screw itself is poor.
2. The length to diameter ratio of the screw is too large.
3. There is a problem with the installation and fixation of the screw. (The installation should be carried out by professional technicians or guided by others).
4. The temperature of the material barrel is set too low, and the shear force on the screw rotation is too large.
5. When the injection molding machine starts cold, the viscosity of the raw materials inside the barrel is too high.
6. The raw materials used contain too hard metal or non-metallic impurities.
