PET is a material that is usually molded into plastic containers. It is an excellent packaging material. It is light in weight, although it is strong and durable. With time, this material has turned out to be the best production material as it does not react with the drinks and foods. The companies are making use of Bottle Machine to deal with this material. This machine molds this material into the desired product quite efficiently.

PET is a germ-free material due to which the companies are turning to use it. For that reason, the demand for the pet blowing machine is on the rise. This machine turns the simple PET material into the bottle.

The Blow Molding Process

The extrusion blow molding process produces plastic bottles of various sizes and shapes. Millions of people use these bottles daily for soda, water, cleaning products, food, and more. With this process, low-pressure air of around 25 to 150 psi is forced into a parison. Multiple materials are used, including Low-Density Polypropylene (LDPE), High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), Polyethylene Terephthalate (PET), and Polypropylene (PP).

A parison with a conventional downward extrusion is inserted into the mold cavity until reaching the required length.

The neck ending catches and holds while the bottom end pinches closed as the tube closes.

A blow-pin is interested into the neck end of the hot parison while compressed air inflates it to the shape of the mold cavity. Simultaneously, the process creates the threaded opening.

Once the mold sufficiently cools, it opens, ejecting the finished bottle along with excess plastic that was trimmed off from around the neck and bottom portions.

petblowingmachine are planned to produce heat-resistant and normal containers. They are not able to produce bottles of diverse sizes. However, Bottle Blowing Machine 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.
