Rapid Prototyping & CNC Prototype Machining
Turn a CAD file into a functional prototype in days. Ginwate makes CNC-machined, 3D-printed and sheet-metal prototypes in Dongguan, China, to tolerances as tight as ±0.005 mm, with no minimum order quantity and most CNC prototypes shipping in 3 to 7 working days.

Rapid prototyping is the fast manufacture of a physical part directly from a CAD model, so you can test form, fit and function before investing in production tooling. We prototype with the same processes and materials we use for production, CNC machining, 3D printing and sheet metal fabrication, so your prototype behaves like the real part, not an approximation.
Three Ways We Prototype
CNC Prototype Machining
Functional metal and plastic prototypes in production-grade materials, milled and turned to ±0.005 mm. The closest match to your final part.
Learn more3D Printing
SLA, SLS and metal printing for fast-form and fit checks, complex geometry and low-cost early iterations, often overnight.
Learn moreSheet Metal Prototypes
Laser-cut, bent and welded enclosures, brackets and panels, prototyped in the same process used for production.

Frequently Asked Questions
What is rapid prototyping?+
Rapid prototyping is the fast manufacture of a physical part from a CAD file so you can test form, fit and function before committing to production tooling. We use CNC machining, 3D printing and sheet metal fabrication to make prototypes in days, in the same materials as your final part.
How fast can you make a CNC prototype?+
Most CNC machined prototypes ship in 3 to 7 working days. 3D-printed parts are often faster. You receive a detailed quote with a free DFM review within 1 to 12 hours of uploading your CAD.
Is there a minimum order quantity for prototypes?+
No. There is no minimum order quantity. A single prototype is welcome, and the same setup scales straight into low-volume and full production.
What materials can you prototype in?+
Aluminum, stainless steel, titanium, brass, copper and tool steels, plus engineering plastics such as PEEK, POM, ABS and nylon. Prototyping in the production material gives the most accurate functional test.
What tolerances do you hold on prototypes?+
Standard tolerances of ±0.005 mm, with tighter tolerances down to ±0.001 mm on critical features. Prototypes are inspected to the same standard as production parts, with CMM reports on request.
