Production machining for repeat OEM programs.
Repeat production runs require disciplined process control, stable fixturing, and predictable inspection. Northline runs production programs with documented setups, in-process checks, and SPC for qualified parts.

Prototype Machining
Prototypes are programmed, fixtured, and inspected the same way production parts are — so the path from a first article to a qualified production program is short, predictable, and well-documented.
CNC Milling
Production milling on Haas VF-series equipment with documented setups, in-process inspection, and DFM review on every quoted program — prototype through long-running OEM production.
Inspection & Metrology
Inspection is integral to manufacturing — not a checkpoint after the fact.
FAQ
Engineering FAQs
The questions engineering and procurement teams ask most often before a first quote.
What production volumes do you support?
From small batch repeat orders to multi-thousand-piece annual programs. Volume affects equipment selection and quoting — discuss expected EAU at RFQ.
Can you handle blanket releases or scheduled production?
Yes. Scheduled releases are common for OEM programs and reviewed during contract setup.
Do you provide PPAP?
Yes — Level 3 PPAP is available for qualified production programs.
