Our Company

JI Machine Company is a woman owned Machine Shop based in San Diego, California and situated in it's own 21,000 sq. ft. facility located in the high tech Sorrento Mesa - Golden Triangle area of San Diego.

We began in 1976 with the commitment: "To offer our customers more than just compliance to their specifications." We have worked closely with our customers to meet the challenges of: extremely close tolerances, completing complex jobs on time, in budget and exceeding their quality expectations. The growth resulting from this effort has allowed us to build a stable team of expert craftsmen who specialize in precision machining for the aerospace, fiber optic, medical, subsea, and commercial industries. Components are manufactured for a wide range of applications from underwater cable connectors, space hardware, military weapons systems, and medical devices ranging from eye socket gauges to brain probes. We are experienced government contractors and subcontractors.

We provide each of our customers with the same exceptional service and personalized attention - regardless of size. Most important is our commitment to customer satisfaction and pride in workmanship.
