PET bottle blowing machine blowing process is divided into two parts
The preform is irradiated with infrared high-temperature lamp, the embryo body part of the preform is heated and softened, the position of the bottle mouth is not heated, and the bottle mouth needs a special cooling device for cooling operation in order to keep the bottle mouth without deformation.
2, blowing molding
This stage is to preheat the preform has been placed in a good blow mold bottle, the cylinder by its high pressure inflation. Pull the preform to the desired shape of the bottle.
Automatic bottle blowing machine by manipulator operation will be blowing the two operations together to complete, eliminating the need for manual pre-heating the preform into the blowing process. Greatly speed up the production rate.
