Common problems and solutions in the blow molding process of high-speed blow molding machines
1. How to handle the accumulation of material at the bottom of bottles produced by the blow molding machine?
Analysis: The common reason for material accumulation in bottles is improper adjustment of the stretching rod. It is recommended that the stretching ratio of the preform to the bottle body be 1:2.5 (excluding the bottle mouth), while also adjusting the heating temperature and extending the pre-blowing time.
2. What to do if the bottle mouth produced by the blow molding machine is deformed?
Analysis: Deformation of the bottle mouth generally occurs during the heating process of the preform, where the drive chain transfers temperature to the bottle mouth. During heating, temperature accumulates, causing the bottle mouth to bulge and deform. At this point, it is necessary to increase the air cooling or water cooling for the bottle mouth. If conditions permit, customers can refer to the practices of imported machines by installing air conditioning in the production workshop to maintain the ambient temperature at a normal level.
3. How should the blow molding machine be operated, and which components should be checked regularly?
Analysis: As long as the operation is strictly followed according to the instructions in the high-speed blow molding machine product manual and regular performance checks are conducted. However, the hidden dangers of the equipment mainly lie in the sealing of the water jacket and air jacket. For example, if the water jacket and air jacket are damaged, the maintenance work can be quite troublesome.
