When you're running a tight prototype run and need that first batch of surgical instrument parts turned around in under a week, we've got bandwidth—3 to 7 days for samples is pretty standard, but confirm lead time if you're pushing teh 2200mm length limit.

Tolerance sits at ±0.01mm to ±0.05mm depending on geometry, which is better than most standard ISO 2768 M work, and surface roughness can go form Ra 0.1 up to 3.2—usually we see buyers specifying Ra 0.8 for implantable parts. Material options cover alumnum, brass, bronze, steel, stainles, titanium, and plastic; we're running about 150,000 pieces a month across 5-axis centers, CNC lathes, and mill-turn machines.

It handles M1×0.25mm threads no problem, and for medical stuff like diagnostic equiment or implantable parts, it's solid—though it's not suited for anything requiring sub-micron tolerances or exotic alloys like Inconel (that's a different setup). Surface treatments include anodizing, powder coating, electropolishing, and plating, but you'll want to specify early if you need electropolishing because of that it adds roughly 5 days or so.

Anyway, you send a STEP or IGS file, we quote in a day or two, and bulk orders run 20 to 30 days typically. It basically works for both one-off prototypes and mass production—just don't expect miracles on lead time if you're ordering 50,000 units overnight.
We don't have a strict MOQ for prototypes—we can handle as few as 1 piece for sampling. For bulk production, we typically start at 100 pieces, but we can flex based on your project needs.
Yes, we can hit that tolerance in titanium within the standard 3-7 day window for samples, as long as the part size stays under 2200×1800×150mm. The 5-axis setup lets us hold tight tolerances even on harder materials.
We ship ISO 2768 M compliance documentation standard with every bulk order. If you need a specific tolerance class or custom spec—like for medical implantables—we can certify to that too, just note it in your file upload.
Absolutely. Our 5-axis machines can reach Ra 0.1 on complex geometries, and electropolishing works well on internal features in stainless steel. Just make sure your STEP or IGS file clearly defines those surfaces.
We custom-pack each part based on its dimensions and finish—think foam-lined crates for large aluminum pieces and anti-corrosion wrapping for machined surfaces. For bulk orders over 500 pieces, we use standardized cartons with internal dividers.
