Our Quality Assurance Framework

Strict Quality Objectives

≥95% customer satisfaction

≥99% finished product qualification

≥95% on-time delivery, zero fire/safety accidents

Rigorous Inspection Processes

IQC for raw materials, IPQC during manufacturing,
FQC for finished products, and OQC before shipment.

IQC – Incoming Quality Control

Visual appearance, structural dimensions, function, and performance of raw materials (profiles, wires, LED chips, PCBs, electronic components, etc.).

Raw materials are moved to warehousing upon approval.

IPQC – In-Process Quality Control

1. Dielectric Strength Test (Hi-Pot Test).

2. Power Output (after illumination).

3. Semi-finished Product Aging Test.

4. Waterproof Test.

5. Performance Test.

FQC – Final Quality Control

1. Finished Product Aging Test.

2. Finished Product Insulation Test.

3. Grounding Performance Test.

4. Finished Product Performance Test.

OQC – Outgoing Quality Control

1. Label Content Confirmation.

2. Photometric Testing (light color, voltage, power).

3. Performance Test.

Products are released for outbound shipment after approval.

RMA Processing Flow

Customer submits application
