150,000 pieces annually is our full capasity, but we've pushed 180,000 in a pinch—that's turning, milling, and 5-axis all running simultaneously across shifts. Most buyers don't realize they can mix material batches within teh same run, say 200 units in aluminum then switch to stainless for the next 50 without a tooling penalty, which basically cuts their per-piece cost by about 15% if they plan it right.
We hold ±0.01mm on critical features like bearing seats but relax to ±0.05mm for cosmetic bracketry—it's not one-size-fits-all. Surface finish hits Ra 0.1 on polished steel, but for brasses with fine threads down to M1×0.25mm, you'll typically see Ra 0.8 or so because chip evacuation gets tricky at that size. 3. Lead time for a first-off prototype runs 10-14 business days from STEP or IGS file receipt, though we've done urgent 5-axis jobs in 7 days when the shop schedule allowed. The 2200mm x 1850mm x 350mm envelope handles most chassis plates and housing assemblies, but anything over 250mm in Z axis needs workholding verification first—check with engineer before ordering. 4. 1kg to 50kg is our usual shipping bracket for production orders, and we quote FOB Shanghai or EXW depending on your freight forwarder arrangement. Bulk pricing drops significantly at 500+ units, especially for simpler geometries like turned bushings or flat milled plates—some buyers combine two unrelated parts on the same PO to hit that threshold. 5. Surface treatment options matter more than people think: anodizing hides minor scratches, powder coating adds 0.05-0.1mm to dimensoins, and electroless nickel plating gives you corrosion resistnce without building up edges. We've had clients specify polished brass for decorative fixtures only to find out it's not heat-tolerant above 180°C, so check your thermal range before committing. 6. Drawing formats get sorted internally—we run STEP into CAM directly, but PDF hand sketches take an extra day for interpretation and usually cost a separate quote clarification fee. The defects in machining, not design issues or material-selection errors, so have your engineer double-check stress points on the 3D model before we cut.
For tighter tolerances like ±0.01mm, we usually need about 2-3 weeks from drawing approval, depending on complexity. Standard tolerances around ±0.05mm can be quicker, around 7-10 days.
No, we don't have a strict MOQ. We can handle single prototypes or small batches just as easily as large runs up to 150,000 pieces per year.
Yes, we can supply mill certificates for aluminum, steel, and stainless steel upon request. Just let us know which material you need docs for, and we'll include them with your shipment.
Our machines can handle parts up to 2200mm in length, 1850mm in width, and 350mm in height. If your part is larger, we might need to split the job into multiple setups.
We can combine polishing and anodizing in sequence—first polish the surface to the desired smoothness, then anodize. Just specify the order and Ra value you need, and we'll adjust accordingly.
