FactoryBest-fit scenarioMain mismatch
Ningbo LiyangMotorized blinds bundled supplyPure motor or very large fabric-only sourcing
Ningbo DooyaStandalone curtain motorsFinished blinds or blind fabric
Shandong YumaLarge-scale blind fabricSmall tests or motorized bundles
The decision shortcut
Need the motor and blind delivered as one coordinated product? Start with Liyang. Need motors only and care heavily about IP exposure? Start with Dooya. Need large volumes of blind fabric and value public-company compliance signals? Start with Yuma.
Do not combine contradictory priorities
If your answers point in different directions, the product scope should be clarified before contacting a factory. A buyer requesting both a small test and large-scale fabric economics is not ready for a reliable verdict.
