High-Quality CNC Machined Parts from RuiYi
At RuiYi, we specialize in providing high-quality CNC machined parts from China. With a large fleet of CNC machining centers, we ensure fast turnaround times and competitive pricing for both prototyping and low-volume production.
CNC Machining vs. 3D Printing for Prototyping
For Western customers exploring rapid prototyping, we often recommend sourcing plastic prototypes locally due to speed and shipping logistics. However, for metal parts, especially those made via 3D printing technologies like SLA, SLS, or DMLS, it’s important to understand both the advantages and limitations.
Pros of 3D Printing:
- Ideal for complex geometries and fast iterations
- No tooling required — parts can be printed overnight with just 3D CAD files
- Useful for artists and concept designers needing abstract shapes
Limitations of 3D Printing:
- Size restrictions on larger parts
- Material limitations — printed materials often simulate rather than replicate real properties
- For instance, SLA “ABS-like” or SLS “nylon-like” materials may not be reliable for functional testing
Why Choose CNC Machining?
CNC machining remains the most reliable solution for functional prototypes, especially when real materials are needed. At RuiYi, we leverage China’s cost-effective labor market to deliver top-tier results.
Key Advantages:
- Supports a wide range of materials: aluminum, steel, ABS, PC, PMMA, POM, and more
- No compromise on mechanical properties
- Greater dimensional accuracy and surface quality compared to 3D printing
Extensive Surface Finishes:
We offer a variety of post-processing options to meet your design and production needs:
- Sanding, texturing, matte and gloss painting
- Polished clear finishes
- Anodizing, powder coating
- Chrome/nickel plating and PTFE coating
Post-Processing Capabilities
CNC machining is also suitable for post-processing other manufacturing methods:
- Large plastic parts (e.g., ABS or PC/PMMA) can be bonded after machining
- Laser welding available for metal parts
- Ideal for finishing 3D printed parts: reaming, threading, polishing, or precise hole adjustment
- Delivers smoother and more refined surfaces than raw 3D prints
Cost and Quality Comparison
CNC machining typically offers:
- Up to 50% cost savings compared to 3D printing for similar parts
- Superior surface finish and material authenticity
- Reliable performance for both testing and functional use
Whether you need a one-off prototype or a small production batch, RuiYi’s CNC machining services provide the ideal balance of cost, speed, and quality.
