Blowing machine mainly divided into three categories: extrusion Bottle Machine , injection blowing machine and special structure of the bottle blowing machine. Processing technology is divided into one-step and two-step two. One-step and two-step blowing machine molding process, mainly used in pet and Bopp hollow container molding. Both have their own characteristics, are widely used. In comparison, the two-step method is more suitable for concentrating the production of preform, dispersing and blowing bottles, and one-step equipment is more suitable for the online production of beverage enterprises.

Blowing machine blowing process:

1 First of all, the heating of the plastic embryo into the mold,

2 of the use of the clamping cylinder to tighten the mold;

3 and then the use of high-pressure or mechanical structure to make the embryo mold locked;

4 medium and high pressure pre blowing gas, while stretching the cylinder action to make the embryo mold swell;

5 high-pressure blowing, bottle embryo according to mold stereotypes, and keep pressure for a certain time;

6. The high-pressure release in the molded bottle and the cylinder reset--take the bottle.

Factors To Consider Before Purchasing Bottle Blowing Molding Machine

Before purchasing the bottle blow molding machine, it is imperative for you to consider some factors. These factors are mentioned below:


Productivity is the first and foremost factor to consider. Whether you want to create bottles on a small or large scale, the machine should be capable of meeting your demands. There are some characteristics of the equipment that affects its efficiency and productivity. If a machine has maximum productivity, then it will be able to create bottles on small and large scales.


The other factor to consider before buying the molding equipment is versatility. The standard petblowingmachine are planned to produce heat-resistant and normal containers. They are not able to produce bottles of diverse sizes. However, automatic machines can produce bottles in diverse designs and sizes. The latest bottle blowing machines can save time. They can produce diverse types of bottles in an efficient way. More information click petblowingmachine
