Vertical injection molding machine is one of the processing equipments for plastic processing. Faced with huge market demand, the processing efficiency of injection molding machine is a basic goal pursued by all plastic products processing enterprises. There are many aspects that affect the processing efficiency of a vertical injection molding machine, such as the operation technology of a worker or the injection molding technology of an injection molding machine. When the vertical injection molding machine has injection molding problems, it needs to be solved in time.

When the vertical injection molding machine has obvious noise problems during the injection molding process, it is very likely that the parts are damaged or adjusted incorrectly. There are mainly the following aspects.

If the concentricity deviation of the coupling causes noise, it is necessary to replace the part with the technology or adjust the concentricity appropriately. Bearing wear or mechanical lack of lubricant or loose parts can cause significant noise. The main source of power for the oil pump is therefore particularly important and requires frequent maintenance or overhaul. In particular, the hydraulic oil pressure in the fuel tank, whether it is blocked or lacking in oil, and whether the viscosity of the hydraulic oil is too high or not, etc., can cause significant noise in the established injection molding machine. In order to have a better use effect of the vertical injection molding machine, the vertical injection molding machine is well maintained and repaired before and after use.
