Blow Molding

Blow molding is often considered over standard injection molding when a hollow-shaped part is required. Extrusion blow molding consists of extruding a hollow tube of molten plastic commonly referred to as a parison. The parison is then clamped between two mold halves and expanded into the desired shape by inflating it with compressed air. After cooling, a hollow part emerges. Injection blow molding is a more exacting process which takes a pre-made pre-form and stretches it over a core rod to typically make a cylindrical container.
