About Plastic Injection Molding | Norco Plastics, Inc.
Norco Plastics, Inc. operates from an 88,000-square-foot facility in Chino, California. The company was founded in 1974 by the Williams family in nearby Norco, California, starting with just two machines. Today, the second generation of the Williams family continues to own and manage the business, maintaining its roots as a family-owned manufacturer. The company specializes in custom plastic injection molding with a clamping force range of 30 to 2,800 tons across 25 presses. Its capabilities include insert molding, multi-material molding, and a suite of secondary operations such as hot stamping, robotic part removal, assembly, and surface finishing. The facility runs 24/7 and employs approximately 60 people, offering end-to-end services that extend to mold maintenance, supply chain management, inventory control, and logistics distribution throughout Southern California. Norco Plastics serves a diverse set of industries, including construction (weather-resistant barriers and structural supports), storage and logistics (impact-resistant totes and stackable containers), consumer products (food-grade, BPA-free housewares), agriculture (irrigation components), automotive (tight-tolerance components), and medical (non-invasive devices with cleanroom-capable production). Its customer base spans Los Angeles, Orange, Riverside, San Bernardino, and San Diego counties. The company differentiates itself through its large-tonnage capacity—highlighted by the 2023 installation of a 2,800-ton press—round-the-clock production, and ISO 9001:2015-compliant quality systems with coordinate measuring machine capability to ±0.0001 inch. Its five-decade history and continued investment in equipment position it as a single-source partner for both precision components and large-scale molded parts.
