ACHIEVING UNIFORMITY IN STRETCH-BLOW MOLDING THROUGH PARISON TEMPERATURE CONTROL

In stretch-blow molding (SBM), how well the parison—essentially a hot PET tube—is heated is super important for making quality bottles. This parison gets stretched and blown into shape, and for the whole process to work smoothly, the temperature needs to be just right and consistent. If the temperature isn't even throughout the parison, it c
