PET Bottle Blowing Troubleshooting is a skilled work needs lots of professional acknowledge on PET treatment process, bottle stretch blow molding machine and other auxiliary equipment. The production engineer should know much about PET preform treatment for the storage and tranportation, PET bottle blowing machine`s electronic circuit information,electrical diagram,hydraulic diagram, infrared heating system, compressed air drying system and other automatic controlling systems. Below we had listed the common pet bottle manufacturing defects and solutions of PET bottles blow molding for your checking. Feel Free to Contact Us if Any Questions

So it will need to be adjusted according to the PET preforms` height, thickness, workshop indoor temperature, etc. A reheating step is then necessary to condition the preforms to the appropriate temperature distribution (slightly above the glass transition, which is typically ~75°C). This stage is generally performed using infrared (IR) heaters, taking advantage of the semi-transparent behavior of PET with regard to IR radiation. the objective function is reduced by 60% of its initial value after the first iteration, and by more than 80% at the end of the optimization process. Consequently, the thickness distribution of the formed bottle is 80% more uniformed after optimization. The algorithm converges after five iterations, which involves only 10 objective-function evaluations (that is to say, 10 FE simulations). On average, one cost-function evaluation requires 26 min CPU. Thus, the total CPU time required for the optimization is ~ 3 h 20 min. PET Preform reheat Temperature versus time inside and outside of the PET preforms for the oven configuration from publication.
