Three Things You Need to Know About the PET Blow Molding Machine
Jul 29, 2024
What is the PET stretch blow molding machine?
PET bottle blower is defined as a production machine used to make bottles of different shapes and sizes. How it works is not complicated: depending on the applied air pressure, the bottle blower blows air into the heated bottle preform and is shaped with a specific PET bottle mold wrapped around it.
What is the overall production process of the bottle blowing machine?
The first step is to pre-heated. The PET bottle preform body was heated to a suitable molding temperature, and the inner and outer walls of the preform body were heated evenly. Because the mouth of the bottle is stereotyped, there is no need for heating. Therefore, the bottle mouth needs to be cooled during preform body heating.
The second step is to blow the bottle. The uniformly heated bottle preform is sent into the bottle blow mold through the chain, and the aseptic high pressure gas is blown into the bottle preform through the middle of the mandrel for circumferential stretching, so that it is inflated to close to the mold wall, and then cooled.
The third step is demoulding. After blowing the bottle, the machine begins to exhaust and demoulding.
Step four, transmit. The molded PET bottle is sent to the next bottle station through the conveyor belt, and it is pulled out and blown out by the lower cylinder. If it is in the FESTA blowing-filling-capping combiblock machine, it will be transmitted through the steel wave wheel to the next process.
Where can I use the bottle blower machine?
If you look around at the products that use PET bottles, you can see that PET bottles can hold not only liquids, but also semi-solids. The use of plastic blow molder is in the factories that produce these products, including:
The pharmaceutical industry.
The food industry.
Beverage industry.
Cosmetics industry. .
Of course, packaging companies that provide PET plastic bottles for the above industries can also use PET bottle blow molder suitable for mass production.
