Below is a list of Plastic Injection Mould manufacturers from Joliet, Illinois. The plastic injection mould process is used to fabricate parts with a range of complexities, from simple shapes to precision parts of geometric complexity. While the majority of plastic injection mold processes use thermoplastics such as ABS, polysulfones, polycarbonate, polyamides and fluoropolymers, a small amount of plastic materials such as thermosets, elastomers and biodegradable plastics are used as well.
