What Norco Plastics does
Norco Plastics, Inc. is a family-owned custom plastic injection molder founded in 1974 in Norco, California, and now operating from an 88,000 sq. ft. facility in Chino, CA. The company runs 24/7 production across 25 presses spanning 30 to 2800 tons of clamping force, with shot capacity up to 1000 oz, making the 2800-ton press a key differentiator for large structural components. Its core service is custom injection molding, complemented by secondary operations (hot stamping, assembly, robotic removal, insert molding), tooling maintenance, supply chain and logistics, and quality assurance via Brown and Sharpe CMM (±0.0001 inch) with SPC monitoring.
The business serves six primary industry verticals — Automotive, Construction & Infrastructure, Medical & Healthcare, Agricultural & Irrigation, Consumer & Retail Products, and Storage & Distribution — with vertical-specific qualifications including USP Class VI material handling, batch traceability for medical components, Cpk ≥ 1.33 capability for automotive, and California building-code compliance for construction. Customer count is approximately 120, and pricing is quote-based and project-specific, with DFM feedback bundled in at no additional charge.
Go-to-market is relationship-driven B2B sales targeting Southern California manufacturers across Los Angeles, Riverside, Orange County, San Bernardino, and San Diego counties, supported by a website quote-request system with 24–48 business-hour response. Ownership remains under the founding Williams family, with second-generation leadership (John Williams as CEO, Jack Williams as CFO), and there are no disclosed funding rounds, acquisitions, or plans for public offering.
