Working principle

Automatic Stretch Blow Molding Machine works based on a two-step process. First, the machine uses a preform, which is a tube-shaped plastic piece, to create a preform mold. Second, the preform mold is heated and then stretched in the vertical and horizontal directions to create a bottle-shaped container. During the stretching process, high-pressure air is blown into the container to form it. Once the container is shaped, the machine releases it, and the finished product is ejected. The entire process is automated and can be completed quickly and efficiently, making it a popular choice in many industries.
