So you're looking at custom CNC parts with that ±0.01mm tolerance, and honestly that's where most of teh real-world problems show up—when you need a bracket or a shaft to fit without any slop, and the surface finish has to be 0.8 or better, which we can dial in further if needed.
We've worked with guys building motorcycle brake calipers who just couldn't get the piston bore consistent enough form their previous supplier, and what it does is let us hold that tolerance through the whole run of a few hundred or so parts, using aluminum, steel, or brass—whatever your drawing calls for.
Actually, the EDM capability is something a lot of buyers don't think to ask about, but if you've got internal corners or intricate cavities that a mill can't reach, that's where it saves you, though we usually recommend confirming lead time for that step since it's slower than straight milling or turning.
Most of the automotive accessory guys we deal with go with the mass production option rather than prototypes, but our company can do small batches too—roughly 20 units or so if you're testing a new design, and we'll run the full inspection on every piece before it ships.
It's not suited for anything that needs sub-micron precision or optical-grade surfaces, as the ±0.01mm is tight for general machining but won't hit what a lapping or polishing shop would do, and the 0.8 roughness is pretty much standard for your typical hardware tool or machinery compnent.
Anyway, we usually have stock on common alloys like 6061 aluminum and 12L14 steel, but for brass or copper we'd need a week or so to source it, and the packaging is whatever you need—just tell us if it's going on a shelf or straight into assembly.
We hold ±0.01mm on all specified dimensions in your drawing. If some features can be looser, just note that on the print and we'll adjust accordingly.
Yes, we can issue mill test reports for metals like aluminum and steel. Just request it with your order and we'll include the certs with shipment.
For a run of 5000 parts, expect around 3-4 weeks from approval of the final drawing. That includes CNC milling, turning, and any surface treatment you need.
No strict MOQ for plastics—we can do as low as 50 pieces for prototyping. For mass production, we prefer at least 500 to keep unit costs reasonable.
We pack each part individually in foam or bubble wrap, then into sturdy cartons or crates. For larger runs, we can also do custom labeling or barcoding per your instructions.
