One-Stop Solution: From rapid prototyping to small-batch production—CNC, casting, sheet-metal, and 3D printing under one roof.
Ultra-Low MOQ: Prototype with just a single piece; scale up seamlessly to hundreds.
Tight Tolerances & Fine Finishes: Achieve ±0.01 mm accuracy and Ra 0.8 µm smoothness in metal parts.
Material Flexibility: Standard alloys (6061/7075 aluminum, stainless steel, brass, iron) or custom materials on request.
Fast Turnaround: Prototype parts in as little as 24 hours; small runs delivered within one week.
Quality Assurance: 100% inspection (CMM reports, surface-roughness tests) before shipping.
Smart Machining & Industry 4.0: Integration of IoT sensors and real-time monitoring is driving predictive maintenance and zero-defect yields.
Hybrid Manufacturing: Combining additive (3D printing) with subtractive (CNC) techniques for complex geometries and internal channels.
Advanced Materials: Growth in high-strength, lightweight alloys (e.g., Al–Li, titanium) and metal-matrix composites for aerospace and EV applications.

Q1: What is the minimum order quantity?
A: We accept orders starting from 1 piece for prototypes, with no upper limit for batch runs.
Q2: Which CAD file formats do you support?
A: STEP, IGES, STL, DWG and DXF are all supported. For other formats, please contact our engineers.
Q3: How soon can I get my prototype?
A: Standard lead time is 1–3 working days; expedited service (24 h) is available for urgent projects.
Q4: What tolerance and surface finish can you guarantee?
A: Standard tolerance is ±0.01 mm (±0.005 mm on request). Surface roughness: Ra 0.8 µm (Ra 0.4 µm achievable).
Q5: Do you provide inspection reports?
A: Yes. Parts are 100% inspected via CMM, and we can include detailed inspection reports and photos.
Q6: Can you handle volume production?
A: Absolutely. After prototyping, we can scale to small-batch (dozens to hundreds) or full production runs.
