Low-volume CNC Machining for Production Parts
Reduce part costs with higher quantities of machined parts
Enhanced Machining Capabilities with Our Digital Network
Get anodizing, tighter tolerances, and volume pricing options through our network of manufacturing partners powered by Hubs. You'll find plating (black oxide, nickel), anodizing (Type II, Type III), and chromate coating at scale; tolerances down to ±0.001 in. (0.020mm); and cost-efficient machined parts at higher volume.
Try Digital Network at HubsWe’re not only the fastest manufacturing supplier of machined prototypes but also the most reliable source of on-demand production parts. Why is this important? You have a single-source supplier from concept validation to short-run production.
We offer more competitive pricing at higher quantities in addition to tighter tolerances, hardware assembly, first article inspection (FAI) reporting, material certifications, and additional finishing options like anodizing and chromate plating. It’s CNC machining designed around your project needs—whether prototyping or production.

4 Reasons to Turn to Protolabs for Machined Production Parts
1. Reduced Piece-Part Price with Higher Quantities
Lower your part cost when you order higher volumes of production parts.
2. Inspection Reporting and Certifications
Get added quality assurance from conventional FAI reporting, CoC documentation, and AS9100 certification.
3. More Finishing Options
Choose from anodizing and chromate plating for complete parts from one supplier.
4. Supply Chain Flexibility
Avoid warehousing fees by ordering only the amount (starting at quantity 15) you need each month.

Quality Reporting
When all of your parts are machined at Protolabs you can be assured those parts are going to be produced in one of our AS9100- and ITAR-certified facilities and never outsourced to another machine shop. All parts are inspected for cosmetic conformance to workmanship standards and dimensional conformance on at least three dimensions (typically X, Y, and Z), but with production parts for machining, we also provide conventional inspection reporting like FAIs, Certificate of Compliance (CofC) documentation, and additional certifications like ISO 9001 and AS9100.
