Who we are

Founded in 1979 with five employees, SPMF has grown into a 70-person team dedicated to high-reliability metal finishing and nondestructive testing. Operating from our modern 70,000-sq-ft facility in Sullivan, Missouri, we support complex programs from prototype through production with stable processes, documented work instructions, and lot-level traceability.

Our integrated services include fluorescent penetrant inspection (FPI), magnetic particle inspection (MPI), precision blending and rework, masking, paint, etching, passivation, hardness and conductivity testing, conversion coating, anodizing, fuel-tank coating, and NDT field services. Industry leaders—including Boeing, Lockheed Martin, Cessna, Honda, and Northrop Grumman—rely on SPMF for consistent quality, responsive lead times, and a team that stands behind every part.

Security and compliance are core to how we operate: SPMF is NIST SP 800-171 / DFARS 252.204-7012, and ITAR compliant.
