Custom Rapid Prototyping Services

Accelerate your product development with Kaiao's one-stop prototyping facility in China. From conceptual models to functional testing parts, we combine advanced CNC machining, SLA/SLS technologies, and rapid injection molding to meet your specific project requirements. Our streamlined in-house production cuts traditional lead times down to 1-3 days, offering up to a 30% cost reduction for both high-precision metals and engineering plastics—all backed by rigorous quality inspection.

Core Prototyping & Low-Volume Manufacturing Capabilities

At Kaiao-RPRT, we replace guesswork with precision. Our in-house manufacturing facility is equipped to transition your design from early-stage concepts to functional, production-grade parts. By integrating advanced machining, additive manufacturing, and rapid tooling under one roof, we guarantee tight tolerances and rapid turnarounds for any project scale. 
 

1. Custom CNC Machining (Milling & Turning) 

Engineered for durability and exact specifications. We machine functional metal (Aluminum, Steel) and engineering plastics (ABS, PC) in as fast as 1 day. 
  • Tolerance: Extreme precision down to ±0.001 inches. 
  • Capacity: Large-format milling up to 4000 × 1500 × 600 mm, and turning up to 200 × 500 mm. 
 

2. Industrial 3D Printing (SLA, SLS, FDM) 

The fastest route for complex geometries and presentation models. We produce high-fidelity parts with a standard lead time of 4-6 days. 
  • Tolerance: ±0.2 mm (adding just 0.15% for parts over 100mm). 
  • Capacity: Massive single-piece build volumes up to 1400 × 700 × 500 mm. 
 

3. Vacuum Casting (Polyurethane Casting)

The ultimate cost-effective solution for small batch validation. Achieve injection-molded aesthetic and mechanical quality for up to 20 parts in 15 days or less. 
  • Tolerance: Strict control at ±0.05 mm.
  • Materials: A wide range of resins mimicking production-grade plastics. 
 

4. Rapid Injection Molding & Tooling

Bridge the gap to full-scale production. Ideal for rigorous testing in medical, automotive, and consumer electronics. We offer expedited lead times as short as 5 days. 
  • Tolerance: Mold cavity precision of ±0.05 mm. 
  • Capacity: Accommodating large components up to 1200 × 1000 × 500 mm. 
 

5. Precision Sheet Metal Fabrication

Streamlined fabrication for flat parts and enclosures, ready for testing in just 1-2 business days. Working with aluminum, stainless steel, and copper alloys. 
  • Tolerance: Cutting ±0.2 mm, Bend Angle ±1.0°.
 

6. Finishing & Quality Assurance

A prototype isn't complete without the right finish. We provide comprehensive post-production finishing (painting, anodizing, polishing) backed by rigorous Quality Control (QC) to ensure your parts look and perform exactly as specified.
