19 Jul What Is Extrusion Blow Molding?
Extrusion blow molding is a manufacturing process used to produce hollow plastic parts by inflating a heated plastic tube inside a mold until it takes the desired shape. The process begins by melting plastic resin and forming it into a tube, or parison. The parison is then clamped into a mold and air is injected, causing it to expand and take the shape of the mold cavity. Once the plastic has cooled and hardened, the part is ejected from the mold. Extrusion blow molding is commonly used to produce containers, such as bottles and jugs, as well as other hollow parts, such as toys and automotive components.
