Quality Considerations
What to Inspect
- Repeatability test — Run 100 cycles to the same point, measure deviation
- Path accuracy — Trace a known path (circle, line) and measure deviation
- Thermal stability — Run for 4 hours and re-check repeatability
- Cable dress pack — Check routing quality and strain relief
- Controller quality — UI responsiveness, programming language capabilities
Red Flags
- Manufacturers refusing to share MTBF data
- No CE or ISO certification
- Controller using outdated Windows CE or proprietary OS only
- No English documentation or support
Sourcing Process
Step 1: Define Requirements
- Payload, reach, repeatability, speed, IP rating, environment (clean/harsh)
- Application type (welding, assembly, palletizing, etc.)
- Integration needs (vision, force sensing, conveyor tracking)
Step 2: Get Multi-Brand Quotes
- Contact 3-5 manufacturers or use a sourcing agent like GrabaRobot
- Request FOB pricing, delivery time, warranty terms
- Ask for reference customers in your industry
Step 3: Factory Audit (Recommended)
- Visit the factory or arrange a third-party audit
- Check production capacity, quality control processes
- Request sample or demo unit if possible
Step 4: Order and Logistics
- Standard lead time: 4-8 weeks for stock models, 8-12 weeks for custom
- Shipping: Sea freight ($800-$2,000 per unit), air freight ($3,000-$8,000)
- Import duties vary by country (0-8% typically)
Frequently Asked Questions
How much cheaper are Chinese robot arms compared to FANUC or ABB?
Typically 50-70% cheaper for equivalent specifications. A 6 kg 6-axis robot from Estun costs $10,000-$15,000 FOB vs $30,000-$45,000 for a FANUC LR Mate.
Are Chinese robot arms suitable for precision applications?
Top Chinese brands achieve ±0.02-0.05 mm repeatability, suitable for most industrial applications. For ultra-precision needs (±0.01 mm), FANUC and ABB still hold an edge.
What warranty do Chinese robot manufacturers offer?
Standard warranty is 1-2 years. Estun and EFORT offer 18-month warranties. Extended warranties (3-5 years) are available for an additional 5-10% of the robot price.
