About Plastic Design International Inc
Plastic Design International (PDI Molding) operates from Middletown, Connecticut, where it was founded in 1977 as a short-run prototype R&D business. The company has since evolved into a full-service injection molding resource center with two facilities totaling 55,000 square feet. PDI runs 21 injection molding machines ranging from 35 to 385 tons of clamping force, producing custom plastic parts, overmolded assemblies, and precision molds in-house. Its capabilities span plastic injection molding, insert molding, mold making and tooling, and value-added services such as design assistance, mold flow analysis, and coordinate measuring machine (CMM) inspection. The shop supports advanced quality frameworks including APQP and PPAP, and uses robotic sprue pickers, automated conveyors, and a central MRP system for scheduling and inventory control. The company serves automotive, communications, defense, fire protection, and telecommunications sectors. Past projects include a glass-filled nylon filter housing for an automotive application, a 14-inch thermoplastic antenna housing for communications, an over-molded handheld antenna for defense, a pump housing molded in carbon- and glass-reinforced polyamide for hydraulic filtration, and an inner chamber for a fire protection system. PDI emphasizes its ability to act as a single source from concept through molding and assembly, citing nearly five decades of experience, critical-tolerance expertise, and a documented quality system certified to ISO 9001:2015, ITAR, and RoHS standards.
