Below is a list of Injection Blow Molding manufacturers from Schulenburg, Texas. Injection blow molding, as its name would suggest, is a combination of plastic injection molding and blow molding that creates hollow, thin-walled plastic containers that are smaller and does not have handleware. It is faster than extrusion blow molding, and offers higher precision. Parts may have a threaded neck for screw-on lids, very thin yet strong walls and safety enclosures like those on pill bottles.
