Ci-Dell Plastics

What Ci-Dell Plastics does

Ci-Dell Plastics is a privately held, family-owned custom thermoset plastics manufacturer founded in 1986 in Wisconsin. The company operates a single 30,000-square-foot facility in Mequon, WI, equipped with 23 molding machines — injection and compression presses ranging from 35 to 500 tons, augmented in March 2025 by a new 750-ton Trinks press capable of producing parts up to 55 inches long. It runs 24 hours per day, five days a week, and complements molding with CNC machining, preforming, post-bake processing (Grieve TAH-550 oven), Hexagon CMM inspection, and in-house tool room capabilities for mold build, repair, and maintenance. Materials processed include phenolic, melamine, epoxy, BMC/SMC polyester, diallyl phthalate, and silicone compounds, with MIL-M-14/ASTM D5948 compliant plaques stocked for rapid fulfillment.

The company holds an unusually comprehensive defense/aerospace credential stack — AS9100D, ISO 9001:2015, NIST 800-171, CMMC Level 1 (achieved December 2025 with Level 2 targeted by 2027), ITAR registration, UL, and MIL-M-14 material approval — positioning it as one of a small number of U.S. thermoset molders qualified to supply military specification parts. Named customers span U.S. DoD (Army, Navy, Air Force), Dayton Phoenix, Rockwell, aircraft manufacturers, electrical utilities, and automotive OEMs, with notable legacy-part reproduction work for missile defense radar arrays. Current verticals include electrical/power distribution, defense/aerospace, automotive, industrial manufacturing, appliances, agriculture, medical, and food service.

The business model is B2B custom project manufacturing with quote-based pricing determined by material, part complexity, tooling, and volume; revenue streams include custom molding services, thermoset materials/plaques sales, and tool room services, typically under multi-year contracts. Distribution is direct sales only, with no retail or e-commerce channel. Go-to-market emphasizes educational content (blog, FAQ, industry standards pages), email newsletter, and presence at SPE TopCon conferences, with conversion occurring via online quote request and direct phone engagement.
