Blow Molding is a process used to form thermoplastic materials and PET Blow Molding Machines are widely used for making bottles. Advanced technology in plastics industry has given rise to a number of Blow Molding Machines. The working principle of Blow Molding Machines comes from the 20th century idea of glassblowing. Blow Molding Machine is capable of relatively high production rates if a proper choice is made with proper consideration of the requirement.
The Blow Molding Process: A Brief Introduction
Blow Molding can be categorized into three types:
Injection Blow Molding: The process involves fluxing of the material in a conventional Injection-Molding Machine. The material is then injected into a mold having a controlled temperature and containing a blow stick. This stick carrying the semi-molten material is transferred to a larger mold and the material is blown by air. In this process, the material takes the shape of the mold and is ejected from the Mold after cooling.
Extrusion Blow Molding: The process involves production of plastic material as a tube structure which is known as parison. A cold mold gives the parison instant firmness and this is followed by finishing procedures.
The process of Blow Molding begins by forming a preform or parison out of the molten plastic. Parison can be described as a plastic tube piece with a hole in one end to enable the compressed air to pass through. Rest of the process is followed by fastening the parison into a mold. After this, pressurized air is pumped into it and the plastic material is pushed out to take the shape of attached mold. The part is ejected afterwards by automatic opening of the mold, once the plastic has got cooled and hardened.
Considering above mentioned facts, PET Blow Molding Machines are capable of relatively high production rates. A lot of companies manufacture and supply Automatic Blow Molding Machine, but a proper search is a must for selecting the right source.

Blog. I was excited enough to drop a cokmment :-) I do have 2 questions for you iff it's
allright. Could it be simply me or do some of the comments look as iif they are coming from brain dead
folks? :-P And, if you are writing at other sites, I'd like
to keep up with you. Would you list the complete
urls of your shared sites luke your Facebook page, twitter feed, or linkedin profile?
