Whether you’re developing a new hollow plastic component or looking for a reliable extrusion blow molding partner, our team is here to help. Below are answers to common questions about our extrusion blow molding capabilities and manufacturing process.
Extrusion blow molding is a process in which a continuous tube of molten plastic (called a parison) is extruded and then clamped in a mold, where compressed air inflates it to take the shape of the mold cavity. It is widely used for producing bottles, containers, ducts, tanks, and other hollow plastic components.
Extrusion blow molding offers excellent design flexibility, the ability to produce large and complex hollow shapes, lower tooling costs compared to injection molding, and compatibility with a wide range of thermoplastic materials.
