About M.A.R.'s Engineering Company
M.A.R.'s Engineering Company has operated from San Leandro, California since 1964. The family-owned business began as a precision screw machining shop and has remained under family stewardship for nearly six decades. The company specializes in high-accuracy turned components, running 35 Brown & Sharpe single-spindle screw machines capable of up to five simultaneous operations. Its capabilities extend to multi-spindle screw machining, centerless grinding, CNC milling and water jetting, CNC turning, wire EDM, and in-house finishing — including plating (hard chrome, zinc, black oxide, nickel, gold, Teflon), polishing, and light assembly. A workforce of 50–99 employees handles prototype through production volumes in a single facility. M.A.R.'s serves aerospace, medical, electronics, automotive, chip manufacturing, food processing, heating and cooling, transportation, electrical/utilities, and music industries. Customers range from OEMs requiring complex prototypes to those needing large production runs of precision parts. The company emphasizes a quality system built on dual order review, first-article inspection of five to eight pieces per setup, and a three-stage in-process monitoring method where operators batch parts for dimensional verification. Inspectors walk the line twice daily to confirm conformance.
