Semi-automatic bottle blowing machines are also divided into semi-automatic and fully automatic. This is reflected in the heating of the preform. It is divided into automatic internal heating and semi-automatic internal heating.

1. Automatic internal heating semi-automatic bottle blowing machine
Steps:
①Manually put the preform →②The machine automatically identifies and starts internal heating →③After heating is completed, prompt the manual removal of the preform →④Manually move to the blow molding station for molding
Advantages:
Reduce heating defects caused by human misjudgment (such as crystallization, deformation)
Suitable for the production of high transparency or special-shaped bottles (such as perfume bottles)
2. Semi-automatic internal heating semi-automatic bottle blowing machine
Steps:
①Manually put the preform →②Manually start heating and observe the softening state →③Decide to stop heating based on experience →④Manually transfer to the blow molding station
Risks:
Over-reliance on operator proficiency, novices are prone to increase the scrap rate
Suitable for ordinary containers that do not require high uniformity of the bottle body (such as daily chemical bottles)
There is only one link between the two, but the price of the bottle blowing machine varies greatly. Although automatic internal heating is expensive, the bottles it blows out are transparent and bright, and it also better guarantees the safety of operators and the quality of products.
