Order Process

How It Works — From Drawing to Delivered Parts

Six clear steps, one contact: send a drawing, get free DFM feedback and a quote in about 1 working day, approve the first article, and receive inspected parts — from a 1-piece prototype to batch production.

The Process

Six Steps From Your Drawing to Delivered Parts

What happens after you click send — who does what, and what you receive at each stage.

Send Your Drawing

Upload your 2D/3D files with quantity, material and target surface finish. Your files are kept confidential.

Confirmed receipt, same day

DFM Review & Quote

Our engineers review features, tolerances, material and finish — flagging anything risky or costly with suggested fixes. Free DFM analysis comes with every quote.

Quote + DFM feedback, about 1 working day

Confirm Order

Approve the quote and lead time. Material is prepared and the production process is set up — one price covering machining, finishing, packing and shipping.

Order & production schedule confirmation

First Article

The first part is machined and measured feature by feature against your drawing. An FAI (first article inspection) report with measured data and part photos is available before the batch runs.

FAI report + part photos

Production & In-Process Inspection

After first-article approval, the batch runs on the same machines, with in-process checks on key dimensions so tool wear never becomes a bad batch.

Progress updates on request

Final Inspection, Packing & Shipping

Final dimensional re-check and 100% visual inspection, protective packing for finished surfaces, export paperwork and shipping to your address.

Inside the Process

From Raw Material to Packed Parts

Incoming aluminum bar stock and blanks checked against material certificates

01 · Raw Material — bar stock and blanks checked against material certificates before they reach the floor.

CNC machining centers cutting part features to the drawing

02 · CNC Machining — machining centers and lathes cut features to the drawing, with in-process checks on key dimensions.

Batches running on CNC lathes in the Xinwinf workshop

03 · Batch Production — your batch runs on the same machines that made the first article, in one workshop.

Anodized CNC machined parts returned from surface finishing

04 · Surface Finishing — anodizing, plating and coating through our managed partner network, inspected on return.

Dimensional inspection on the 2.5D vision measuring instrument

05 · Quality Inspection — dimensions re-checked on the 2.5D vision measuring instrument, to the production standard.

Finished CNC machined parts packed for export

06 · Packing & Shipping — foam-separated, bagged and boxed for export, with photos before the cartons are sealed.

Quoting & Lead Time

What to Expect When You Send a Part

  • Quote in about 1 working day for straightforward parts, with free DFM analysis included. Complex parts take a little longer because an engineer actually reads the drawing.
  • No MOQ — one-piece prototype orders are normal, and unit prices come down as quantity grows. Tell us your trial quantity and target batch size; we price both.
  • Prototypes to batch — your first part and your repeat orders run on the same machines with the same inspection standard.
  • Lead time is stated in the quote, covering machining, surface finishing, packing and shipping. Samples travel by international express; batches by air or sea, door-to-door available.
Files We Accept

Send These Formats With Your RFQ

A 3D model gives the geometry; a 2D drawing gives tolerances, threads and finish notes. Send both when you have them — missing the 2D drawing? Send the model with a note on critical features and we’ll tell you what’s missing. ZIP bundles are fine for multi-file projects.

Don’t have a formal drawing yet? A sketch or photo with dimensions is enough to start a conversation — we’ll help shape it into something manufacturable.

Step One Is the Easiest — Send the File

STEP, IGES, DWG, PDF, STL or ZIP — even a photo with dimensions. We’ll confirm receipt, run the DFM review and quote in about 1 working day.
