Rapid Prototyping CNC in China — From Drawing to Part in Days

Prototypes from 1 piece · 3–7 day lead times · ±0.005 mm CMM-verified

Rapid prototyping CNC in China: metal and plastic prototypes from 1 piece, 3-7 day lead times, ±0.005 mm CMM-verified. 220 CNC machines. ISO 9001. Operations are certified to ISO 9001:2015 and ISO 14001:2015, with CMM inspection on every batch.

When a design has to be in your hands this week, CHX Metal machines prototypes directly from your CAD file in Shenzhen. We run 220 CNC machines — turning, milling, 5-axis and Swiss-type — so a single part can be cut, finished and inspected in-house without waiting on subcontractors.

Why prototype on a CNC machine

A CNC prototype is made with the same process that will later make the production part. That means real material properties, real tolerances and no tooling cost — and a direct, repeatable path from one piece to a full production batch.

Unlike 3D-printed models, a machined prototype can be tested mechanically, anodized or plated, and used for fit checks and customer approval.

Materials and finishes for prototypes

  • Aluminium 6061 / 7075, stainless 303 / 304 / 316, carbon and free-cutting steel
  • Brass C3604, titanium TC4, PEEK and other engineering plastics
  • Tolerance ±0.005mm, verified on a CMM
  • In-house finishing: anodizing, zinc / nickel plating, passivation, black oxide, powder coating, laser marking

Prototype lead times

Most metal prototypes ship in 3–7 days from drawing approval; parts that need surface treatment add about 5–10 days. We reply with a quotation and DFM feedback — manufacturability notes, suggested tolerances and cost drivers — within 24 hours of receiving your files.

Express and weekend slots are available on request; tell us your deadline with the enquiry.

From prototype straight to production

The prototype and the production run are made in the same plant on the same machine park. That removes re-qualification, keeps the process repeatable, and lets us scale to as much as 5,000,000 PCS per month in a 5,000 m² facility with 100+ staff.

Every order ships with first-article inspection, CMM dimensional reports and, where required, EN 10204 3.1 material certificates.

Files and information we need

Send a 3D model (STEP, IGES, X_T) or 2D drawing (DXF, DWG, PDF) together with material, quantity, critical tolerances and finish. If your drawings are confidential, we sign a mutual NDA before we receive the files.

Frequently Asked Questions

How fast can you make a CNC prototype? Most metal prototypes ship 3–7 days after drawing approval; parts needing surface finishing add about 5–10 days.

Do you have a minimum order quantity? No. A single prototype is fine, and the same process scales to volume production.

What file formats do you accept? STEP, IGES, X_T, DXF, DWG and PDF drawings.

Can you sign an NDA? Yes — we sign a mutual NDA before receiving your files.

Can the same supplier run the production order? Yes. Prototypes and production come from the same Shenzhen plant, up to 5,000,000 PCS per month.
