UNSPSC 31142800: Dip moldings

Parts produced by dipping a heated mold, mandrel or form into heated or ambient temperature material until desired part thickness is achieved and then, after cooling, removing the part from the mold, mandrel or form.

UNSPSC 31142800 Dip moldings is a Class code that encompasses injection molding equipment and related manufacturing machinery. State and local governments solicit under this code for specialized production equipment, including high-capacity industrial molding machines used in research, prototyping, and manufacturing operations. The issuing bodies include higher-education institutions and their research centers, which procure injection molding systems to support polymer processing, materials science, and product development programs.

The University of Southern Mississippi posted the most recent opportunity under this code, issuing an IFB (Sealed Bid 26-41, RFx #3160008023) on April 26, 2026, for a 110-ton electric injection molding machine with a response deadline of May 12, 2026, at 2:00 p.m. CT. The specifications required a system capable of accepting 14" × 14" × 16" molds, a 40mm screw diameter, 171-gram shot size, and barrel temperatures to 800 degrees Fahrenheit, with a maximum footprint of 179" × 50" to fit the Mississippi Polymer Institute Processing Lab and pass through 82" × 70" doorways. The vendor was required to deliver within 16 weeks, provide one day of installation and familiarization, deliver three days of training (onsite or online), furnish a minimum one-year warranty commencing after installation verification, and supply lifetime online and on-call technical support. Bids were to be submitted using F.O.B. Destination Freight Allowed pricing terms with firm pricing for the contract period, and award was made to the lowest responsible bidder meeting all specifications. Recent activity under this code appears limited to higher-education research and development procurement in Mississippi.
