28mm PET Preforms With Air Seal Price For Sale OEM Company

In the world of packaging, the 28mm PET Preform stands out as a key component in the production of plastic bottles. Known for its strength, lightweight, and recyclability, this preform has become a popular choice for a variety of industries.

Manufacturing Process of 28mm PET Preforms

The production of 28mm PET Preforms begins with the creation of a resin pellet, which is then heated and injected into a mold. This process, known as injection molding, forms the preform's shape. The preform is then cooled and ejected from the mold. The next step is the critical transformation from a preform to a bottle, which is achieved through a process called stretch blow molding. In this process, the preform is heated and then stretched using mechanical force while being blown with air to achieve the final bottle shape.
