Manufacturing Capacity

We’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 choose 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.

Production Capabilities for CNC Machining

Tolerances

Shop tolerance = +/- 0.005
Able to hold +/- 0.002 for reamed holes (print required)
Up to +/- 0.002 feature location on the same side (print required)

Surface Roughness

Flat and perpendicular surfaces = 63 µ in
Curved surfaces = 125 µ in

Surface Finish Options

Multiple surface finishes are available for production machined parts.

Anodizing

This process is typically used on machined aluminum parts. Your anodizing options at Protolabs:

Type II
ROHS compliant
Class 1 (Clear)
Class 2 (Black)

Anodizing applies a thin, protective coat to metal parts, forming a protective oxide layer to create a barrier against corrosion.

Chromate Plating

Your chromate plating options at Protolabs:

Type I, Non-ROHS (Yellow)
Type II, ROHS (Clear)
Class 1A: for maximum protection against corrosion, painted or unpainted
Class 3: For maximum protection against corrosion where low electrical resistance is required

Plating applies a thin metal coating to machined parts for corrosion resistance and improved cosmetic appearance.
