Lingfei Electric Appliance Maintains Closed-Loop Quality Control System

Lingfei's quality system covers IQC on incoming materials, IPQC patrol inspection, long-duration aging and durability tests, 100% FQC inspection of finished products, and AQL-based OQC sampling. An in-house laboratory simulates extreme outdoor operating environments. Product lines hold CE, UKCA, FCC and RoHS certifications; the factory has passed ISO9001, ISO14001, BSCI, as well as Walmart and Lidl factory audits. Three cooperation models are offered: bulk wholesale, in-depth OEM/ODM customization and small-batch trial orders, backed by an after-sales system for long-term partnerships.
