Quality Control

Rigorous Quality Standards & Global Compliance

At Deoulai, we implement a comprehensive 4-stage inspection protocol throughout our manufacturing process to ensure all electronic clocks and timers meet global B2B standards.

QC Protocol

4-Stage Quality Inspection

Our quality inspection process is executed by 15 certified QC inspectors utilizing high-precision testing equipment.

01 Incoming Material Inspection (IQC)

We test all incoming electrical components, LCD/LED display screens, shell materials, and microcontrollers. Only certified components enter our SMT and injection molding lines.

02 In-Process Quality Control (IPQC)

During SMT and assembly, we run functional tests on button response, time accuracy, buzzer volume, temperature/humidity sensor calibration, and display segment completeness.

03 Finished Goods Quality Inspection (FQC)

100% of finished products undergo a 24-hour running aging test to verify long-term stability. Cosmetic audits are conducted to filter out any scratches or assembly gaps.

04 Pre-Shipment Inspection (QA/OQC)

Prior to container loading, random sampling is conducted based on AQL 1.5/4.0 standards. We verify shipping marks, barcode scanning, drop-test performance, and export carton sealing.
