CNC
PROTOTYPING
SERVICES
From CAD to precision-machined prototype in 2–7 days. MW+ delivers engineering-grade CNC prototypes to over 50 countries — tight tolerances, real materials, zero compromise.
Engineering CNC Prototyping,
From Concept to Reality
CNC prototyping uses computer-controlled machining to create functional, dimensionally accurate parts directly from your CAD files — with material properties identical to final production components.
Definition
Computer-controlled machining removes material from solid stock to produce precise, functional components.
Why CNC?
Isotropic strength, ±0.005mm tolerances, 50+ real materials — results identical to production parts.
When to Use
Concept checks, engineering validation, regulatory testing, pre-production bridge runs.
MW+ Accuracy
In-process probing, CMM final inspection, surface roughness testing, material certifications.
MW+ was founded in 2015 in Shenzhen, China — the heart of precision manufacturing. Spanning 5,000 m² with over 70 engineers and operators, we serve 850+ engineering teams across North America, Europe, and Asia. Every prototype ships with full inspection documentation and material certificates.
The MW+ CNC Prototyping Process
Our streamlined 6-step workflow ensures full transparency, fast lead times, and certified quality — from file upload to your door, anywhere in the world.
