What Sinclair & Rush does

Sinclair & Rush, Inc. is a privately-held plastics manufacturer founded in 1950 and headquartered in Arnold, Missouri. The company operates as a multi-processor of plastic components, offering five complementary manufacturing processes — vinyl dip molding, thermoplastic extrusion, thermoforming, injection molding, and foam extrusion — supported by proprietary VynaFlex® plastisol formulations. It is organized around four operating divisions (StockCap for product protection caps, plugs and covers; VisiPak for clear packaging, tubes and clamshells; GripWorks for hand grips and foam sleeves; and Indepak for precision thermoformed trays and containers), each retaining its own brand identity, sales channel and dedicated website.

The company runs manufacturing operations on four continents through eight facilities in the United States (Arnold MO, Fenton MO, Portland OR), the United Kingdom (Maidstone, Rochester), China (Changzhou), and Australia (Riverstone NSW, Campbellfield Victoria). It processes over 30,000 orders and 60,000+ line items annually, producing hundreds of millions of parts per year for more than 20,000 B2B customers across industrial manufacturing, automotive, medical and consumer product verticals. Sinclair & Rush holds ISO 9001:2015 and ISO 14001:2015 certifications valid through June 8, 2028, and is led by President & CEO Brad Philip.

The business model is B2B direct sales through divisional sales teams with quote-based pricing on custom and standard components. Revenue is generated primarily from hardware sales of plastic components for product protection, packaging, and comfort applications. The company demonstrated rapid-response capability when its VisiPak division launched VisiGuard® thermoformed face shields during the COVID-19 pandemic. Ownership remains private with no disclosed institutional investors or parent company.
