EBM or extrusion blow molding is one of three options for blow molding applications. Extrusion blow molding is typically used in products that are long with consistent cross sections. The proper amount of melted plastic material is fed into the mold. Then pressurized air is injected into the parison. This puts equal pressure on the fluid plastic and forces it to the walls of the mold. This is what creates the hollow cavity in the product. The plastic is then allowed to cool in the mold. Finally, the mold is removed and the final product is revealed. The advantage of blow molding is that it can manufacture the product continuously or intermittently.
