Bottle production process

Injection molding, bottle blowing, printing, packaging.

Blowing process

Warm up

      The preform (preform) is irradiated by an infrared high-temperature lamp to heat and soften the preform body to maintain the shape of the bottle mouth. The preform mouth does not need to be heated, so a certain cooling device is required for cooling.

Blow molding

      In this stage, the preheated preform is placed in the blow mold that has been completed, and the interior is inflated under high pressure. Blow and pull the preform (embryo) into the required bottle.

      The automatic bottle blowing machine combines the two operations of bottle blowing through the operation of the manipulator, eliminating the need for manual process of putting the pre-heated preform into the blowing mold. Greatly accelerate the speed of production.
