The Plasticoid Company

What The Plasticoid Company does

The Plasticoid Company is a privately held, veteran-owned custom rubber molder founded in 1946 and headquartered in Elkton, Maryland. The company designs and manufactures custom-molded rubber and thermoplastic components using compression molding (up to 20 million pieces annually for smaller diameters from 0.2 to 8 inches), transfer molding, and thermoplastic injection molding, supported by in-house material mixing that formulates proprietary rubber compounds held as trade secrets. Standard product lines include rubber stoppers and plugs (sleeve, serum, tapered, Twistit®, and expansion/freeze configurations), medicine droppers and assemblies, Class VI implantable-grade bending rubbers for flexible endoscopes, and laboratory accessories.

The company's revenue model combines custom RFQ-driven project work with off-the-shelf standard catalog sales. Custom orders are priced via a Request for Quote system with no public list pricing, while standard products are available for immediate shipment and also distributed through McMaster-Carr. A dedicated government services division pursues federal contracts with published capability statements and a credit application process for qualified buyers. Marketing and customer acquisition rely on a direct-sales website, downloadable technical documents, social media presence, and phone-based sales representatives rather than field sales automation.

Customer segments span medical and pharmaceutical (closures, syringe and IV components, diagnostic parts), industrial and manufacturing (machinery, appliances, automotive, plumbing), laboratory and research, federal government, and consumer goods and cosmetics. The facility operates under CFR 21 guidelines for food and pharmaceutical products and maintains an FDA Drug Master File, supporting qualification as a supplier for regulated end markets. The company has 11-50 employees, no disclosed external investment, no subsidiaries, and no parent company, and operates exclusively within the United States.
