Automotive Parts Through Extrusion Blow Molding

Ejecting a molten liquid plastic material into a preformed mold creates extrusion blow molded plastics. The two halves of the mold are pressed together and air pressure is used to blow in the liquid plastic until it fully fills the preformed cavity conforming to the mold’s shape. When the molding process in completed, the molded plastic component is emptied from the mold and trimmed of any over molded plastic fragments that are not part of the intended finished piece.

The component is allowed to cool until totally solid and the plastic fully congeals and any additional finishing work is then done to the piece. Some molds have multi-injectors and several plastic components can be fabricated at the same time. Multi-molding allows for a more rapid fabrication process.

Advantages of Extrusion Blow Molding for Blow Mold Plastics

The extrusion blow molding fabrication process is appropriate for creating parts that do not have to be highly precise, can have only one thickness, and do not need to have precise exterior finishes. Extrusion blow molding may be a superior and more inexpensive process for you, since injection molding and injection blow molding can be a more costly process due to higher cost of the injector apparatus.
