We support DHL, FedEx, TNT, sea freight, and can do DDP / DAP terms.
- Is there a minimum order quantity (MOQ)?
We have no strict MOQ. We accept prototype trial orders as low as 1 piece. - How can I get an accurate quotation?
Please send us your 3D STEP/IGES file, 2D drawing with tolerance, material requirement, quantity and surface finish. - Can you help with DFM optimization?
Yes. Our engineers provide free DFM suggestions to reduce machining cost and improve manufacturability. - How long is the quotation valid?
Quotation is normally valid for 30 days, subject to raw material price fluctuation.
Pricing depends on material, dimensions, tolerance, quantity and surface finish. Please send your drawings (PDF/DWG/STEP/IGES) and we will provide an exact quote, usually within 24 hours.
The price is based on material cost + machining time + surface treatment + tooling (if any) + packaging and freight.
Our standard quotes are FOB Shenzhen/Dongguan unless otherwise stated. Air or sea freight can be quoted separately according to your destination.
Our price reflects the material grade, tolerance level, full inspection and finishing quality. If needed, we can suggest cost-saving design changes (e.g. relaxing non-critical tolerances) to reduce the cost.
Yes. We provide tiered pricing — the unit price decreases as the quantity increases. Please tell us your target quantity for the best price.
