Extrusion Blow Molding

Custom molding

Since 1978, Agri-Industrial Plastics has won clients and bested competitors with quality blow molding and extrusion blow molding services. We’ve worked in industries as varied as large-scale equipment manufacturing, office supplies and sporting goods.

Extrusion blow molding is not an easy process, but it’s second nature to us.

It all starts with thermoplastic materials that are melted and extruded into a cylindrical tube called a parison. An aluminum mold is closed around the parison, air is injected into the center of the part and forces the plastic outward. The plastic forms to the cavity of the mold, and your part is born.

Once the finished product is cooled and removed from the mold, it is thoroughly cleaned and trimmed of any excess material. This excess, known as “flash,” is ground up and recycled to be used in the creation of other products.
