We support both small and large batch orders, and the MOQ is usually one piece.
The delivery cycle depends on the complexity and quantity of the parts. Generally, it takes 5 to 15 working days. Urgent orders can be expedited.
We ensure it through strict quality control processes and quality inspection standards. We also promise to rework all unqualified products. If you receive unqualified products, we will refund the customer.
We support standard 3D file formats, such as STEP, IGES, STL, DXF, and DWG.
The accuracy of CNC machining can usually reach ±0.01mm, and high-precision machining can even reach ±0.005mm.
The price depends on the materials, processing time, process complexity, and surface treatment requirements. We will provide a detailed quotation according to the customer's needs.
Yes, we do and offer various logistics options, such as air freight, sea freight, and express delivery, to meet our customers' needs.
