Built on decades of family-run machining expertise.
M.A.R.'s Engineering Company Inc. was founded in 1964 by Manuel and Reine Ambrosio and has remained a family-run precision manufacturing business ever since. Over the decades, the company expanded its capabilities through new equipment, a second operations department, multi-spindle capacity, CNC machining, and in-house Wire EDM for tooling and quality control. That steady investment allows M.A.R.'s Engineering to support customers with complete manufacturing services from prototype through high-volume production. The company’s vision is simple: deliver close-tolerance parts, dependable service, and streamlined project management through an integrated in-house workflow that saves customers time, reduces complexity, and maintains consistent quality from first run to final delivery.
M.A.R.'s Engineering manufactures a wide range of custom brass shafts, including smooth and stepped shafts, pins, grooved profiles, threaded-end shafts, and parts with cross-drilled or custom-machined features. Production can be tailored to application-specific diameter tolerances, surface finish requirements, and functional geometry for mechanical, electrical, and industrial assemblies.
