Abstract
The present invention discloses a bottle mouth crystallization heating method, which makes use of external heat energy. When a preform is mounted onto a plug finger of a base by the preform, a first heating source directly heats the external side of the bottle mouth to crystallize the bottle mouth, and a second heating source heats the plug finger of the preform being exposed from the bottom of the plug finger, so that after a heat absorber absorbs the heat, the heat absorber conducts heat energy to the plug finger. The plug finger with heat energy heats the internal side of the bottle mouth simultaneously, therefore to disperse heat energy evenly and rapidly to the internal and external sides of the bottle mouth for crystallization.
