MDC PRECISION LLC

MDC PRECISION LLC specializes in the design, fabrication, and replacement of high-precision optical components for aerospace and scientific instrumentation, with demonstrated expertise in custom viewport manufacturing for extreme environments. Their technical capabilities center on precision machining of optical-grade materials, vacuum-compatible sealing technologies, and optical alignment systems tailored for mission-critical applications. The contractor delivers engineered solutions that maintain optical clarity under thermal cycling, radiation exposure, and high-vacuum conditions—key requirements in space-based sensor systems. Their work on replacement optical viewports for HYMETS systems indicates deep familiarity with spacecraft instrument housings, hermetic sealing protocols, and stringent contamination control standards required for NASA payloads. The company’s primary agency relationship is with the National Aeronautics and Space Administration, where it supports the maintenance and upgrade of scientific instrumentation aboard orbital and planetary missions. This engagement reflects a focused partnership in sustaining legacy space hardware through precision component replacement, suggesting a niche role in long-duration mission sustainment rather than large-scale system integration. MDC PRECISION LLC operates within NAICS 333242, which encompasses the manufacturing of semiconductor processing equipment—though their awarded work aligns more closely with precision optical subsystems used in space instrumentation. This positions them as a specialized supplier within the aerospace supply chain, serving missions requiring ultra-clean, high-stability optical interfaces. Their market presence is defined by technical precision rather than volume, serving high-reliability applications where material selection, surface finish, and dimensional tolerances are mission-critical. As a small business structured as a 2L entity based in Hayward, California, MDC PRECISION LLC operates without federal certifications but leverages localized engineering talent and advanced machining capabilities to meet stringent government requirements. Their geographic proximity to major aerospace R&D hubs enhances responsiveness to mission-critical procurement needs.
