Bottle Blowing Machine

Blow molding machine is widely used by most beverage companies. This bottle blowing machine is mainly blowing pet preformers into pet bottle. Automatic pet bottle blowing machine is convenient and has a large amount of molding.

Blow molding machines are mainly divided into three categories: extrusion blow molding machines, injection blow molding machines and special structure blow molding machines. The processing technology is mainly divided into single stage and two stage. Both have their own characteristics and are widely used. In comparison, the two-step method is more suitable for concentrated production of preforms and dispersed blown bottles; while the one-step method is more suitable for online production of beverage companies.

Main advantages of fully automatic pet bottle blowing machine

Low cost

easy operation and maintenance

Ideal cooling system

Low rejection rate

The blowing process of the plastic pet bottle blowing machine

1) Put the heated plastic preform into the mold;

2) Use a clamping cylinder to tighten the mold;

3) With high pressure or mechanical structure to lock the prototype;

4) Medium and high pressure pre-blowing, while stretching the cylinder action to expand the blank;

5) High-pressure blowing, the preform is shaped according to the mold, and the pressure is kept for a certain period of time;

6) Release the high pressure in the formed bottle, reset the cylinder-take the bottle.
