UNSPSC 31143001: Plastic gas assist molding

Plastic 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 31143001 Plastic gas assist molding is a Commodity code that in practice encompasses the procurement of injection molding equipment and related machinery by state and local entities. The University of Southern Mississippi's recent sealed-bid solicitation for a 110-ton electric injection molding machine illustrates the scope: state and local buyers under this code are acquiring specialized manufacturing equipment for research, laboratory, and production purposes, including the machines themselves along with associated delivery, installation, training, warranty, and technical-support services. Issuing bodies soliciting under the code include higher-education institutions operating research facilities and polymer-processing laboratories; the source shows limited visibility into whether other categories of state or local government—school districts, municipal utilities, transit authorities, or county departments—are active in this equipment class.

The University of Southern Mississippi posted an IFB (sealed-bid) for a 110-ton electric injection molding machine on April 26, 2026, with a response deadline of May 12, 2026 at 2:00 p.m. CT. The machine was specified for installation in the Mississippi Polymer Institute Processing Lab with strict dimensional constraints (14" × 14" × 16" mold acceptance, 40mm screw diameter, 171-gram shot size, maximum barrel temperature 800°F, 179" × 50" footprint) and required delivery within 16 weeks, one full day of installation and familiarization training, three days of follow-on training, minimum one-year warranty, and lifetime technical support. Geographic visibility under this code is limited to Mississippi based on the single recent opportunity in the source; no contract award value or broader state-level or multi-jurisdiction activity data are disclosed.
