Custom Injection Molded Plastic Parts

Built for demanding production programs, from proprietary components to secondary-finished assemblies.

Kingston Plastics supports industrial, transportation, federal, medical equipment, and specialty product lines with efficient molding processes, practical engineering support, and scalable production planning.

We help customers move from part concept to dependable output while balancing tooling strategy, material selection, quality targets, and downstream finishing requirements.

Engineering support that goes beyond simple molding.

New compounds, process controls, and production methods continue to evolve. Kingston Plastics stays current so customers can adopt better manufacturing options without sacrificing consistency or delivery confidence.

We are often brought into programs to reduce part cost, improve repeatability, and raise throughput where existing setups are creating scrap, delays, or too much manual handling.

Product support can include insert molding, thin-wall production, overmolding, plastic-to-plastic, plastic-to-metal, plastic-to-rubber, and plastic-to-paper combinations, along with secondary operations such as hot stamping, sonic welding, assembly, and decoration.

Program Fit

• Short runs, repeat orders, and scale-up support for higher-volume demand.
• Application-specific engineering in put for part cost and manufacturability.
• Secondary operations available when programs need more than molded parts alone.
• Support for demanding industries with strict performance and rejection targets.
