Sub-K Manufacturing, developed by IRLabs, provides precision machining, fabrication, and manufacturing support for scientific, semiconductor, cryogenic, industrial, and instrumentation applications. We specialize in machining-to-print manufacturing, tight-tolerance fabrication, and repeatable short-to-mid volume production support.
Built on Advanced Engineering.
Focused on Practical Manufacturing.
Sub-K Manufacturing was developed from the engineering and fabrication environment behind IRLabs’ cryogenic, infrared, and semiconductor support systems.
IRLabs has supported projects where precision, consistency, and attention to detail are critical—from scientific instrumentation and vacuum-compatible hardware to complex mechanical assemblies used in demanding research environments. That experience shapes the way Sub-K approaches production-focused machining and fabrication services today.
Our team specializes in machining-to-print manufacturing, tight-tolerance fabrication, and repeatable production processes designed to support both prototype and ongoing manufacturing needs. Every project is approached with an emphasis on responsive communication, practical problem-solving, reliable lead times, and consistent execution.
Whether supporting instrumentation companies, semiconductor-related applications, or industrial technology teams, Sub-K Manufacturing delivers precision manufacturing solutions backed by hands-on engineering and manufacturing experience.
