Extrusion Blow Molding

Extrusion blow molding is a manufacturing process used to produce hollow plastic objects, such as bottles. In this process, plastic material is melted and then extruded into a hollow tube called a parison. This parison is then placed into a mold, and air is blown into it, causing the plastic to expand and take the shape of the mold. Once cooled, the mold opens, and the finished hollow plastic item is ejected. This efficient method allows for high-volume production of lightweight, durable containers with consistent quality.
