ABSTRACT
Blow molding allows producing small to large, hollow, doublewall parts that require exceptional rigidity, heat deflection, flame retardance, toughness, and impact strength. Blow molded parts are made by forming a round parison. Industrial blow molding equipment is becoming much more scientific. The equipment and the process are more reliable and predictable due to design improvements and microprocessor advances in operating the basic equipment. In the early stages of selecting the proper equipment, it is necessary to identify the part or parts to be produced on the equipment. With blow molding, large parts can be produced independently of mold flow or large clamping capacity associated with injection or structural foam molding. An accumulator head is used to store a certain amount of melted plastic material developed by the extruder and transferred into the accumulator head through a melt transfer adapter. The extruder is used to deliver a homogeneous and stable melt to the accumulator head.
