About Indiana Rubber & Plastic, LLC
Indiana Rubber & Plastic, LLC was founded in 1936 in Indianapolis, Indiana, and has operated continuously for three generations. The company began as a specialist in custom molded plastics and rubber and has expanded its capabilities while remaining focused on its core expertise. The company provides turnkey service from prototyping through high-volume production. Its processes include rubber molding (compression, transfer, injection, and LSR/LIM), plastic injection molding, extrusion of both plastics and rubber, die cutting, lathe-cut rubber, machined plastics, and bonded rubber-to-metal components. Prototyping uses 3D printing, SLA, rapid molding, and silicone molds. Production volumes span prototype runs of 1–50 pieces, short runs of 1–5,000 pieces, medium runs of 5,000–25,000 pieces, and high-volume orders exceeding 25,000 pieces. The facility operates high-tonnage presses with large platens for oversized parts and maintains on-site tooling to match mold size to demand. Indiana Rubber & Plastic serves customers requiring custom molded rubber and plastic components, including those needing food-grade and military-specification materials. Its product portfolio includes grommets, gaskets, seals, bumpers, diaphragms, bushings, extrusions, mounts, formed hoses, boots, and washers or spacers. The company differentiates itself through competitive pricing driven by innovation, an in-house technical team of designers, CAD drafters, chemists, and laboratory resources, plus access to custom compounders. It emphasizes a "plastics and rubber" breadth—adding urethane, silicone, and thermoplastic elastomers—and a commitment to staying within its three generations of core knowledge. Transparent communication throughout the supply cycle and proprietary Amazing Tool$aver® low-cost tooling methods further define its approach.
