OEM partners across the Midwest and North America.
Headquartered in Elk Grove Village, Illinois, Northline regularly supports OEMs and industrial manufacturers throughout the Midwest and across North America — with documented quality, tolerance control, and repeatable process.
Built for regulated, high-reliability programs.
Aerospace
Tight-tolerance milling and turning in aluminum, titanium, and nickel alloys — with AS9102-format First Article Inspection, mill-certified material traceability, and setups that repeat from first article into scheduled releases.
Defense
Domestic, single-facility manufacturing with controlled technical data handling, certified material traceability, and documented inspection on the characteristics your program flows down — from first article through years of repeat support.
Medical Device
Small, feature-dense instrument and equipment components held to tight diametral tolerances and controlled surface finishes, with material lot traceability and documented inspection that carries from first article into scheduled releases.
Robotics & Automation
Structural housings, drive components, and end-of-arm tooling where bore-to-bore and feature-to-feature relationships decide assembly fit — with DFM feedback on every quote and setups that carry from prototype into qualified production.
Industrial Equipment
Repeat-production parts released against blanket POs and kanban schedules, held to controlled setups with inspection documentation sized to your quality system rather than to the maximum available paperwork.
Battery Manufacturing
Electrode handling fixtures, cell assembly tooling, and structural components held to tolerances that have to add up across an assembly — with fast turns on revisions during commissioning and consistent duplicates as lines are replicated.
Electronics
Housings, heat-spreader bodies, connector hardware, and test fixturing where board and connector fits, sealing-surface finish, and hole-pattern position determine whether an assembly closes — with outside finishing coordinated through qualified processors.
Packaging & Food Processing
Stainless and engineering-plastic components built for caustic washdown and high-cycle service, with cleanable geometry reviewed at DFM, certified material on request, and change parts remade quickly when a line is down.
Rooted in Chicagoland. Shipping nationwide.
Operating from the Elk Grove Village industrial corridor keeps Northline within a day's freight of most Midwest OEM plants, with nationwide shipping from the Chicago area for programs beyond the region.
