Northern Iron & Machine

What Northern Iron & Machine does

Northern Iron & Machine is a full-service iron foundry and machine shop operating as the St. Paul, Minnesota location of The Lawton Standard Co. The company produces grey, ductile, and austempered ductile iron (ADI) castings up to 250 lbs in a five-furnace foundry, using two automated green-sand molding lines — an Osborne 30 (30"×30"×12" flasks) and a DISA Match 130 capable of up to 130 molds per hour — fed by three 1500kw coreless induction furnaces producing 35–45 tons per shift at approximately 4,500+ tons of annual output. Roughly 80% of production is higher-value ductile and ADI iron, with the balance in gray iron.

The castings flow into an in-house machine shop with 14+ CNC machines (horizontal, vertical, turning, and automated four-axis systems) capable of tolerances to ±0.0005 inches, supported by CMM inspection (8-micron volumetric accuracy) under Statistical Process Control targeting Cpk ≥1.33. An on-site metallurgical lab performs elemental analysis via optical emission spectrometry, nodularity testing, tensile testing, and Brinell hardness, while computerized solidification modeling is used to optimize casting designs before production. Value-added services — paint, subassembly, and shipping — are delivered in-house, making the facility a single-source supplier of machined castings ready to assemble.

The company sells exclusively through direct enterprise field sales to heavy industrial OEMs in locomotive, construction, agricultural, trucking, and oilfield equipment markets, with audited/certified supplier status at Caterpillar, WABTEC, GE Transportation Systems, Case Corp., and Fairmont Tamper. Pricing is quote-based, contract-driven, and not publicly disclosed. Certifications include ISO 9001:2015 (renewed April 2023), ISO 14001, ISO 45001, and TPG Casting accreditation from the Performance Review Institute (audit closed September 10, 2024; 18-month term). The company has 51–100 employees, was founded in its current form in 1906 (with predecessor activity dating to 1892), and was acquired by Lawton Standard in August 2022.
