Proto Manufacturing, Inc.

Proto Manufacturing, Inc., headquartered in Taylor, Michigan, manufactures and delivers x-ray diffraction systems and analytical scientific instrumentation to federal research, development, and defense agencies as a prime contractor (98% of recent awards), competing predominantly in full-and-open procurements without set-aside designations. The company operates across both small-business set-asides and unrestricted competitions, with recent prime work spanning the Department of the Navy, Department of the Army, the Air Force Academy, NASA, and the National Institute of Standards and Technology.

Proto's customer base is concentrated in defense and civilian research agencies. The top five customer organizations by award count account for 61% of recent awards: the Naval Air Systems Command places eight awards valued at $107 thousand combined; the National Institute of Standards and Technology places seven awards valued at $305 thousand combined; Naval Air Warfare Center places six awards valued at $2.8 million combined; the Army's Research Development and Engineering Command places three awards valued at $96 thousand combined; and the Air Force Materiel Command Research Laboratory places three awards valued at $116 thousand combined. By potential value, Naval Air Warfare Center dominates at $2.8 million across six awards, followed by the Defense Logistics Agency Troop Support with a single $1 million award. Recent representative work includes a $182,025 Total Small Business purchase order from the National Institute of Standards and Technology for a field-deployable x-ray diffraction system (awarded September 4, 2026, completing February 12, 2027), a $123,450 Total Small Business order from Naval Information Warfare Systems Command for an x-ray diffractometer system (July 7, 2023), and a $104,996 full-and-open Air Force Academy purchase order for a tabletop powder diffractometer (September 30, 2024).

Proto's capability portfolio is tightly specialized in x-ray diffraction instrumentation, stress measurement systems, and analytical laboratory equipment. The vendor delivers equipment procurement, on-site installation, training, calibration, preventive maintenance, and warranty support. Top NAICS categories reflect this focus: Research and Development in Physical, Engineering, and Life Sciences (11 awards), Analytical Laboratory Instrument Manufacturing (9 awards), and Instruments and Related Products Manufacturing for Measuring and Controlling Industrial Process Variables (8 awards). Top PSC codes are Laboratory Equipment and Supplies (12 awards), Physical Properties Testing and Inspection (5 awards), and Maintenance/Repair/Rebuild of Laboratory Equipment (5 awards).

Activity has declined substantially over the past five years—from two awards in 2022 to one in each of 2024, 2025, and 2026—reflecting the project-based, low-volume nature of specialized instrumentation sales. Only one award faces recompete in the next twenty-four months (combined potential value $182 thousand). Proto carries minimal subcontract exposure: one sub-award to the University of Dayton as prime in April 2025 for SUSTAINMENT AND COMBAT READINESS CAPABILITIES (SABR-C) XRD Services. Total combined potential value across the forty-four awards in the recent portfolio is $5.8 million, with $5.7 million already obligated.
