Quality Assurance
CMS ensures every prototype meets production-level quality standards through a strict, ISO-certified inspection process. Our quality system includes first-article inspection, in-process checks, and final dimensional verification using CMM, optical measurement, surface testers, and hardness analyzers. Each prototype is reviewed for accuracy, surface quality, material consistency, and assembly fit, ensuring reliable performance during testing and validation. Inspection reports and material certificates are available upon request.
Advantage of Prototype machining
1 Low cost，no MOQ
If you only need to make 1-20 prototypes, CNC machining is the best option for the price. Unlike injection molding and 3D printing methods, CNC prototyping does not require a lot of time to prepare molds, as long as you have 3D drawings, you can start processing immediately, with high precision, fast speed and low price
2 High Tolerance
CNC machined prototypes have high precision, depending on the precision of the machine tool, CNC Machining Shops maximum prototype tolerance can reach 0.01mm, which is very helpful for functional prototype manufacturing and functional testing.
3 From prototype to production
In most cases, prototyping is the last step in mass production. Prototypes help test product functionality and product pre-sale releases, and when everything is ready, prototypes can be replicated in batches to speed up production.
What is rapid prototype machining?
Rapid prototyping technology is a comprehensive technology that integrates material forming, CAD design, CNC machining, laser cutting and other technologies, and is a system technology that realizes the integration from part design to three-dimensional solid prototype manufacturing.
The basic principle of rapid prototyping is to use CNC machining, 3D printing, injection molding, casting and other processing techniques to quickly manufacture product prototypes or parts of any complexity based on 3D CAD models, the final product accuracy and manufacturing cost and delivery cycle. Depends on the processing method you choose.
