We replace guesswork with measured parts. KAIAO's own Shenzhen floor takes your design from first concept to functional, production-grade components across six in-house processes — CNC machining, vacuum casting, reaction injection moulding, rapid injection moulding, sheet metal and finishing. Because nothing is outsourced, tolerances and lead times stay under our direct control on every project, from a single model to a 1,000-part bridge run.
1. Custom CNC Machining (Milling & Turning)
Engineered for mechanical durability and precise print specifications. We process functional metal alloys (Aluminum, Stainless Steel, Brass) and engineering plastics (ABS, PC, PEEK, POM) with rapid setups.
- Tolerance: Standard machining tolerances down to ±0.025 mm (±0.001 inches).
- Capacity: Large-format milling up to 4000 x 1500 x 600 mm; CNC turning up to 200 x 500 mm.
2. Reaction Injection Moulding / RIM
The fastest route for complex geometries and presentation models. We produce high-fidelity parts with a standard lead time of 4-6 days.
- Tolerance: Standard machining tolerances down to ±0.025 mm (±0.001 inches).
- Capacity: Large-format milling up to 4000 x 1500 x 600 mm; CNC turning up to 200 x 500 mm.
3. Vacuum Casting (Polyurethane Casting)
Our most cost-effective route to 10–2,000 near-production parts. Four vacuum casting machines replicate injection-moulded look and feel from a silicone tool in a 2000 × 1200 × 1000 mm chamber, with dimensional stability held at ±0.1 mm.
- Tolerance: ±0.1 mm
- Capacity: 4 machines; chamber 2000 × 1200 × 1000 mm; 1–2,000 parts per tool
- Materials: PU resins mimicking ABS, PC, PMMA and rubber-like elastomers
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: mould cavity ±0.05 mm
- Capacity: up to 1200 × 1000 × 500 mm; 100–10,000+ parts
- Lead time: tooling from 5 days
5. Precision Sheet Metal Fabrication
Flat parts, brackets and enclosures cut and bent in-house and ready in 1–2 business days. We work aluminium, stainless steel and copper alloys with cutting accuracy of ±0.2 mm and bend angles held to ±1.0°.
- Tolerance: cutting ±0.2 mm; bend angle ±1.0°
- Lead time: 1–2 business days
- Typical parts: enclosures, brackets, chassis, mounting plates
6. Finishing & Quality Assurance
Every part is finished and inspected before it ships. Four dedicated spray booths use coating systems from PPG, DuPont and AkzoNobel, supported by 50+ skilled hand-finishing staff for polishing, texturing and colour matching. Bead blasting, anodising, powder coating and custom paint are all done in-house, and final dimensions are verified on our Hexagon CMM and FARO arm.
- Finishing: bead blast, anodise, powder coat, colour-matched paint
- Coatings: PPG, DuPont, AkzoNobel
- Inspection: Hexagon CMM + FARO arm, report on request
