What PRL does

PRL, Inc. is a privately held ferrous and non-ferrous high-specification sand casting foundry headquartered in Cornwall, Pennsylvania, with a second manufacturing facility in Lebanon, Pennsylvania. Established over five decades ago and operating as a subsidiary of Nautilus Integrated Solutions since 2012, the company supplies mission-critical castings and machined components to the U.S. Navy and broader defense sector, commercial and naval nuclear power, the railroad industry, and general industrial customers where component failure is not an option. PRL's principal customers are government and large industrial buyers operating in submarine, naval nuclear, and rail applications.

PRL operates a vertically integrated manufacturing model that consolidates foundry production, AOD (Argon Oxygen Decarburization) refining up to 18,500 lbs per heat, sand casting up to 12,000 lbs per piece, heat treating, welding, full-spectrum NDT/NDE (radiography for steel thicknesses from 0.25 to 11 inches, magnetic particle, liquid penetrant, ultrasonic, hydrostatic), and CNC machining. The Lebanon facility, branded the 'Home of Precision,' spans 107,000 square feet of manufacturing space with 37 machines and is qualified to CNC machine components to tolerances of two ten-thousandths of an inch. The company maintains an in-house metallurgical laboratory and 19 Level III NDE personnel certified to ASNT-TC-1A, with 14 of those also qualified to ASME requirements.

PRL generates revenue through project-based, custom-quoted contracts covering castings, machined components, NDT/NDE testing, and finishing or upgrading services. Pricing is determined per project based on alloy, complexity, tolerances, required certifications (NAVSEA, ASME, MIL-I-45208), and volume, with multi-year contract cadences typical of defense and nuclear work. The company uses a direct enterprise sales motion, processing quote requests submitted through its website and responding with customized proposals for each project. Distribution is exclusively direct, with no resellers or third-party channels, and operations are entirely domestic within Pennsylvania.
