About Anfinsen Plastic Molding Inc.
Anfinsen Plastic Molding operates from Oswego, Illinois, where it was founded in 1935. The company began by molding small parts constrained by the technical limitations of the era and has since expanded into large-scale, complex-geometry molding alongside a full assembly warehouse that manages customer-supplied hardware, metal, custom packaging, and other polymer goods. The shop runs 31 injection molding presses ranging from 40 to 1,000 tons, producing millions of thermoplastic parts annually from materials such as ABS, polycarbonate, HIPS, acetal, and acrylic. A 100,000-square-foot assembly facility provides discrete assembly, riveting, sonic welding, heat bending, and barcode-driven inventory management for customer-supplied components. In-house decorating capabilities include painting, custom masking, pad printing, hot stamping, and color matching. Tooling engineering, quality control, and logistics fulfillment with ERP-backed warehousing and drop shipping round out the service offering. Anfinsen has maintained a decades-long presence in the point-of-purchase display industry, serving retail channels that include Walmart, Walgreens, Target, gas stations, and convenience stores. The company works closely with the marketing and design firms behind those brands and cites customers such as Edge Products, Kirkland Foods, and Global Brands. Projects typically involve time-sensitive retail rollouts where speed and on-the-fly problem solving are critical. Leadership emphasizes a culture of urgency developed in fast-paced, competitive markets. The company states it quotes custom projects quickly, provides a detailed roadmap, and excels when pressure is highest, aiming to deliver without sacrificing quality.
