UNSPSC 31143002: Structural foam gas assist molding

Structural foam part produced by an injection molding process involving injection of high pressure nitrogen gas into the resin melt stream immediately after injection of the resin allowing the gas to displace a portion of the resin and force the resin to the walls of the mold.

UNSPSC 31143002 Structural foam gas assist molding, a Commodity code, covers injection molding equipment and related manufacturing hardware that state and local governments procure for educational and research purposes. The University of Southern Mississippi's recent sealed-bid solicitation for a 110-ton electric injection molding machine illustrates the actual work category—state and local entities buy production-grade molding equipment with precise technical specifications, delivery and installation commitments, training and support packages, and extended warranty coverage. Issuing bodies under this code appear limited; the recent activity shows higher-education institutions, specifically university research and processing labs, as the primary procurement driver rather than broad municipal or county purchasing.

The University of Southern Mississippi posted the sealed-bid opportunity (BID 26-41, RFx #3160008023) in April 2026 with a response deadline of May 12, 2026, seeking equipment capable of accepting molds with maximum dimensions of 14" x 14" x 16", a 40mm screw diameter, and a shot size of 171 grams, with delivery lead time not exceeding 16 weeks, one full day of installation and familiarization, three days of onsite or online training, and a minimum one-year warranty with lifetime technical support. No contract award value or incumbent contractor information was disclosed. Geographic activity is currently limited to Mississippi based on available records; broader state or regional patterns are not evident from the recent opportunity set.
