Pierce-Roberts Rubber

What Pierce-Roberts Rubber does

Pierce-Roberts Rubber Company Inc. is a privately held custom rubber components manufacturer founded in 1911 and headquartered at a 40,000 square foot climate-controlled facility in Trenton, New Jersey. The company produces custom molded rubber parts using compression molding, transfer molding, and injection molding processes, supported by in-house custom rubber mixing and formulating (1 lb to 100 lb batch sizes, 15 to 90 durometers), rubber-to-metal bonding, CNC machining (four milling centers and five lathes with ±.00015" accuracy), and rapid prototyping using an Objet 3D printer with 1-4 day lead times for 1-50 unit runs. Tolerances of ±.001 to ±.005 inches are quoted across product categories. The firm sells primarily to B2B customers in aerospace, medical, military, gaming, marine, electronics, hydraulic, fire protection, food processing, scientific, and air/fluid control industries, with named use cases including lottery balls (Pantone color matching, ±0.25 g weight tolerance), aircraft bumpers (MIL-DTL-16232, ASTM E1444), audiometer ear cushions, and conductive satellite gaskets. Pierce-Roberts holds ISO 9001:2015 certification (since 2001), NIST registration, and ITAR registration, and it acquired Par-Lin Precision Products Inc. in 2023 to add close-tolerance machined insert capabilities under a unified quality system. Revenue is generated through quote-based, project-priced custom manufacturing contracts with multi-year billing cadences, delivered direct-to-customer globally.
