Extrusion blow molding is a manufacturing process used to create hollow plastic parts. It begins with melting plastic pellets and forming them into a continuous tube, known as a parison. This parison is then inflated inside a mold, taking the shape of the desired product, such as bottles or containers. The process is efficient and cost-effective, making it popular for producing large quantities of items. After cooling, the mold opens, and the finished product is ejected. Extrusion blow molding is widely used in industries like packaging and consumer goods due to its versatility and ability to create complex shapes.
