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 to strengthen quality control and responsiveness. Today, M.A.R.'s Engineering continues to serve manufacturers that need close-tolerance turned components, dependable repeatability, and streamlined production support from one source. Our vision is to help customers simplify sourcing by combining prototyping, machining, finishing, and light assembly in a single facility while maintaining the craftsmanship, accountability, and service mindset that have defined the company for nearly 60 years.
M.A.R.'s Engineering manufactures a wide range of precision turned parts used in renewable energy equipment, including shafts, pins, bushings, sleeves, fittings, connectors, threaded components, couplings, and custom miniature parts. These components can be produced with secondary features such as grooves, threads, cross-holes, milled flats, and fine surface finishes to meet demanding assembly and performance requirements.
