What Wilbert Plastic Services does

Wilbert Plastic Services is a US-based plastics contract manufacturer headquartered in Belmont, North Carolina, operating four specialized manufacturing facilities in North Carolina, Pennsylvania, South Carolina, and Minnesota with a combined footprint exceeding 700,000 square feet. The company produces and ships more than 400,000 plastic parts and assemblies every day. Its core processes are injection molding across a 60-ton to 2700-ton press range (including multi-material two-shot, MuCell microcellular foam, long fiber glass, gas-assist, and structural foam capabilities), heavy-gauge thermoforming (single-sheet, twin-sheet, pressure forming, LWRT, robotic trimming, sonic welding, and low-pressure foam fill), industrial paint (three dual 7-Axis robotic booths, solvent-borne and water-based options, EPA compliant), and downstream assembly, sequencing, kitting, vendor-managed inventory, and returnable packaging. The company also offers upstream engineering services spanning program management, CAD/CAE in PTC Creo, SolidWorks, CATIA, and UGNX, tooling engineering, GD&T tolerance analysis, prototyping, and validation testing.

Wilbert sells exclusively on a B2B contract-manufacturing basis to market-leading OEMs across automotive, heavy truck, industrial, medical, and lawn & garden / recreational vehicle verticals. Revenue mechanics are per-contract, negotiated privately with each OEM program (pricing not publicly disclosed); value-add services such as JIT delivery, sequenced delivery, serialized traceability, and kitting are positioned as extensions of the core molding and thermoforming offerings rather than as separate revenue lines. The go-to-market motion is enterprise field sales through direct OEM relationships rather than channel or distribution. The company holds IATF16949 and ISO 9001 certifications at its White Bear Lake, MN thermoforming facility and has received a Society of Plastics Engineers Gold Award for a twin-sheet thermoformed shelving program for a major truck OEM.

Wilbert is privately held and operates as a subsidiary of Marmon Group, a Berkshire Hathaway company, with HR, recruiting, and careers administered through Marmon's Workday portal. The company was founded approximately 50+ years ago and created WilbertU, a cloud-based internal learning program offering 300+ self-paced courses, in 2015 as a workforce development investment.
