Dalton Manufacturing

What Dalton Manufacturing does

Dalton Manufacturing Group Inc. is a privately held, American-owned precision CNC machining and metalworking company founded in 1936 and headquartered in Amesbury, Massachusetts. The company operates a single 15+ person facility equipped with CNC machining centers (DMG CMX 1100, Mori-Seiki 5100, Matsuura 510V, Fanuc Robodrill) and CNC turning centers (Mori-Seiki NL-1500, Nakamura-Tome TMC-15M/20/SC-250, Okuma L1420) supported by manual milling, grinding, finishing, and inspection equipment (Brown & Sharpe, Mitutoyo, Starrett, Sunnen bore gages). Its core capability is 4th axis machining of milled and turned parts with tolerances as tight as +/- .0002 of an inch and 100% in-process inspection. The company serves three primary verticals: US defense contractors (aerospace, naval, weapons, radar systems; titanium, cobalt chrome, nickel alloys), medical device and instrument manufacturers (surgical and electronic medical devices in stainless steel, Invar, Kovar, Inconel), and laboratory/testing equipment developers.

Dalton generates revenue through project-based, quote-driven custom CNC machining engagements, with all pricing negotiated per part specification, material, tolerance, and quantity. It supports short-run, long-run, and prototype production, and layers on supply-chain services such as Kanban, blanket orders, Just-In-Time, and Ship-to-Stock inventory systems. The go-to-market is sales-led and direct: customers reach Dalton by phone (978-388-2227), website contact form, or referral. The company positions itself as a long-term supply chain partner rather than a job shop, coordinating with customer purchasing, engineering, and production teams.

The business is differentiated less by unique technology than by accumulated certifications and tenure: ISO 9001:2015 certification (achieved 2020), active pursuit of CMMC for DoD compliance, SBA Small Business status, and registrations in SAM, DSBS, and DIBBS, plus multiple FSC and NAICS codes. It is a "Ship-to-Stock" supplier, meaning customers accept parts directly into inventory without incoming inspection — a meaningful operational endorsement. There is no public revenue disclosure, no external funding, no parent company, and no disclosed M&A activity; ownership and control appear to remain with founders/management across its 85+ year history.

Core offering

Dalton Manufacturing is a precision CNC machining and metalworking company that produces custom milled and turned parts for aerospace & defense, medical device, and laboratory equipment manufacturers. The firm operates CNC machining and turning centers with 4th axis capabilities, holding tolerances as tight as +/- .0002 of an inch, and supports short-run, long-run, and prototype production. It supplements machining with process design, outside service coordination, and supply chain programs such as Kanban, blanket orders, and Ship-to-Stock inventory systems.

Product overview

Dalton Manufacturing is a precision CNC machining and metalworking company offering services as both a single unified offering and through modular add-ons. The core service is Precision CNC Machining & Metalwork, which includes 4th axis machining of both CNC milled and turned parts, precision turning with tolerances as tight as +/-.0002, CNC milling, and rotary milling operations. Supporting the core service, Dalton offers Supply Chain Partner Services (Kanban, Just In Time, blanket orders, Ship-to-Stock inventory systems), Flexible Manufacturing Partner engagement (adding capabilities, avoiding staffing costs, or outsourcing complex manufacturing), and Process Design Services. All services are provided 100% in-house with flexible capacity to serve as a complete manufacturing partner or supplement a customer's existing operations.
