What CNC Prototyping Services do We Offer?
Our prototyping services offer a wide range of processes to help your parts achieve tight tolerances. Whether you need CNC milling, precision machining, or bulky machining, we can provide it.
Our rapid prototyping services can quickly turn your digital designs into physical models, allowing you to verify mechanical performance and identify design flaws early.We are not only processing parts, but also accelerating your product iteration cycle.
Our CNC milling process is capable of manufacturing prototype parts with various complex geometric designs and can meet your rapid production requirements. CNC machining tolerance can be controlled within a tight tolerance of ±0.01 mm.
For prototype parts with extremely high symmetry and roundness requirements, our CNC Turning service delivers excellent surface finish and dimensional accuracy.
When your design is extremely difficult to process, our 5-axis CNC Prototype service can handle it well. The process is capable of machining highly complex organic curved surfaces and deep cavities in a single setup.
Traditional cutting tools are difficult to machine sharp internal corners or extremely hard materials. At this time, we will use EDM to machine prototype parts. This process also ensures extremely high precision, typically maintaining tolerances stricter than ±0.005mm.
Our CNC Swiss machining can process microscopic parts or parts with extremely high aspect ratios and also ensures components with micron-level precision.
The fastest and lowest cost. 3D printing allows your prototype components to be manufactured and delivered in the shortest time through additive manufacturing, and there is no need to consider the complexity of the parts.
Our injection molding services are suitable for small to medium volume production, ensuring that your parts have perfect mechanical properties, color, and surface texture. And the cost of a single piece is still low.
Prototype Parts We Manufacture
Over the years, our CNC prototyping services have produced more than 300 types of prototype parts, each with a unique structure. And we will formulate a reasonable manufacturing plan based on the drawings to ensure that the parts meet your specifications.

We offer a complete solution from 3D printing (proof of concept), CNC machining (functional testing) to rapid injection molding (low-volume pilot production).
Surface Finishes for Your Prototypes
Our CNC prototyping services can make your prototypes look, feel and perform as you require.
The process is suitable for prototype components that urgently need to verify the internal structure and also does not have any coatings or chemical treatments to change part dimensions.
This process can significantly improve the fatigue strength and wear resistance of prototype parts, and the protective layer is very thin, almost without affecting the original precise tolerances.
We alter the internal microstructure of the metal through a precisely controlled heating and cooling process. This process significantly increases the core strength and hardness of the prototype component.
Unlike traditional electroplating, electroless nickel plating does not cause coating accumulation problems and can perfectly cover the surface of prototype parts. Moreover, this process can also greatly improve the corrosion resistance of parts.
We use bead blasting process to eliminate the knife patterns left by CNC machining on the prototype surface, resulting in a uniform matte texture, and the process is cost-effective.
The anodizing process uses an electrochemical reaction to create a dense, corrosion-resistant oxide film on the surface of the prototype component. The process is well suited for consumer electronics and high-end products.
After powder coating surface treatment, the surface of the prototype will form a tough protective layer, which is very suitable for outdoor equipment casings, automotive parts, etc.

For custom machining prototype parts, our standard lead time is typically between 3 to 7 working days, depending on the complexity of the parts, material machinability, and required surface treatment processes.
The cost typically ranges from $10 to $60, depending on the geometric complexity, tolerance requirements, and surface finish demands of the prototype part.
In prototype CNC machining, the most commonly used metal materials are aluminum alloys, and the most commonly used plastic materials are ABS and POM.
Typically, prototypes are divided into four key types: proof-of-concept prototype, visual Ppototype, working prototype and engineering prototype.
The most commonly used tools are high-precision CNC machines, especially three-axis, four-axis, and five-axis milling machines and lathes.
A Prototype Machinist is a highly specialized manufacturing expert who is not only proficient in CNC programming (CAM software) and multi-axis machine tool operation, but also transform designers’ 3D CAD models into physical, fully functional parts.
