4M Sigma

We are a veteran-owned, small business having resided at this location since 1990. All design, electrical/electronic fabrication, assembly, calibration, and functional test are performed at Interbay. We also currently use 15 Boeing D1-4426-approved and mil-spec approved specialty processors within a 20-mile radius of Interbay. These sub-contractors have been carefully audited and selected by our Operations Management. All outside process work is consistently monitored via on-site visits and facility inspections. Approximately 175 piece part and raw material manufacturers & distributers round out our supply chain.
