The best supplier filter is a short list of pointed questions. A capable factory answers them with data and documents; a risky one answers with vague reassurances.
Motor and electronics
- Which motor brand do you use, and can you provide test data?
- What is the duty cycle, noise level, and rated load?
- How do you source and test the control box and wiring?
Frame and durability
- What material and wall thickness is the frame?
- Do you weld on jigs or freehand?
- What load and cycle testing do you run, and can I see reports?
Compliance and documentation
- Which certifications do you hold, and for which models and markets?
- Will I receive test reports and certificates with my order?
- Who handles certification if I need a new market?
Commercial terms
- What is the MOQ, sample cost, and sample lead time?
- What are production and re-order lead times?
- What are the payment terms and Incoterms?
- What is the warranty and spare-part policy?
How KCAI approaches this
KCAI answers these directly: dual-motor frames with single/triple options and a quiet domestic motor (OKIN optional on select frames), carbon steel jig-welded frames rated at 250 kg, 110–240V wide-voltage electronics, and a low MOQ with refundable samples, 30-day lead time, and a defined motor and frame warranty.
Frequently asked questions
What is the one question that separates good factories?+
Ask for load-test and cycle-test reports for the exact model you are buying. Factories that test properly can produce them; others stall.
Should I ask for references?+
Yes, but treat them as one signal. Ask specifically about on-time delivery and how they handle non-conforming product, not just whether the product worked.
