The machine works by using a process called blow molding, where a heated plastic tube (known as a preform or parison) is inflated with air, causing it to expand and take the shape of the mold. Once the plastic has cooled and hardened, the mold is opened and the bottle is ejected, ready for trimming and final inspection. Features of such machines may include high efficiency, energy saving, easy operation, high output with low rejection rate, and long service life. They may also come with advanced
