What Macfab does

Macfab Manufacturing Inc. is a Canadian precision CNC machining job shop headquartered in Mississauga, Ontario, operating a single 42,000+ square foot facility equipped with 53 CNC machines (including 3-, 4-, and 5-axis mills, Swiss-style lathes up to 9-axis, turn-mill combinations, and surface grinding) and an ISO Class 7 cleanroom. The company produces complex, tight-tolerance metal and plastic components for five primary verticals—medical devices, aerospace, space/satellite manufacturing, security and defence, and energy/environment—holding AS9100:D, ISO 9001:2015, ISO 13485, RoHS, REACH, and Canadian Controlled Goods Program certifications to qualify as a supplier to those regulated industries. Differentiated technical capabilities include automated First Article Inspection, helium mass spectrometry leak testing, off-gas testing to NASA-STD-6001, precision rotor balancing, micro machining to 10 µm tolerances, and full back-to-birth ERP traceability, with advertised tolerances down to ±0.0025 mm on critical space-grade features.

Macfab's go-to-market is direct enterprise field sales: quote-based engagements with engineering collaboration from design-for-manufacturability through prototype and high-volume production, plus recurring Vendor Managed Inventory (VMI) and Kanban programs that include a proprietary AI layer for dynamic inventory replenishment. Revenue is generated through per-part/quote pricing on custom machining work and managed-services recurring revenue on VMI/Kanban accounts; the customer base is enterprise-led, with named logos including Smiths Detection, Rocket Lab, Standard BioTools, and Perkins across North America, the UK, Europe, Australia, and Asia. Since 2022 Macfab has operated as a wholly-owned subsidiary of Exchange Income Corporation (TSX), grouped with sister Ben Machine entities under EIC's diversified industrial portfolio.
