semi-auto blowing machine and fully-auto blowing machine

  The blowing process of a bottle blowing machine is divided into two parts. There are usually semi-automatic bottle blowing machines and fully automatic bottle blowing machines.

  The semi-automatic bottle blowing machine has two separate parts: a heating furnace and bottle blowing. Workers need to place the heated preform into the bottle blowing mold and operate the bottle blowing process. The production efficiency is slow, and the yield of finished products is affected by the proficiency of workers. The advantage is low investment cost, suitable for users in the initial investment stage and with low production capacity demand.

  The fully automatic bottle blowing machine combines the two bottle blowing operations through the operation of a robotic arm, eliminating the need for manual placement of preheated bottle preforms into the blowing mold. Greatly accelerated the production rate. The steps are as follows:

1. Bottle preform heating

The preform is irradiated through an infrared high-temperature lamp to heat and soften the body of the preform. In order to maintain the shape of the bottle neck, the preform neck does not need to be heated, so a certain cooling device is required to cool it.

2. Blow molding

This stage is to place the preheated preform into the pre made blow mold, inflate it with high pressure, and blow and pull the preform into the desired bottle.
