Blow molding is a manufacturing process used to create hollow plastic parts by inflating a heated plastic tube, known as a parison, inside a mold cavity. This process follows three main methods: extrusion, injection, and stretch blow molding. Extrusion blow molding involves extruding a melted plastic tube that is then inflated. Injection blow molding starts with injecting plastic into a preform and then blowing it to shape. Stretch blow molding, commonly used for PET bottles, stretches the preform vertically before blowing to increase strength. This technique is favored for its versatility in shaping complex geometries, excellent for producing containers, bottles, and other hollow shapes in various industries including beverage, automotive, and consumer goods.
