At Guangzhou Xinyi Photoelectric Technology Co., Ltd., quality is not just a department—it is our lifeline. As a vertically integrated manufacturer and exporter, we maintain absolute control over the entire lifecycle of our automotive lighting products, from raw material selection to final dispatch.

1. Professional QC Team & Personnel

Our Quality Assurance (QA) department is comprised of over 20 seasoned engineers and technicians with an average of 10 years of experience in the automotive lighting industry.

1. IQC (Incoming Quality Control): Rigorous screening of raw materials, including high-performance LED chips, premium polycarbonate lenses, and automotive-grade housing plastics.

2. IPQC (In-Process Quality Control): Real-time monitoring of the assembly lines. Our technicians conduct hourly spot checks to identify and rectify any deviations instantly.

3. FQC/OQC (Final/Outgoing Quality Control): A 100% comprehensive inspection before products leave our facility, ensuring that every unit meets our stringent internal standards

2. Systematic Quality Control Process

We adhere to the ISO 9001:2015 and IATF 16949 standards to ensure our workflow meets international automotive benchmarks:

1. Strict Material Sourcing: We only partner with Tier-1 suppliers for core components to ensure thermal stability and long-term durability.

2. Automated Assembly & Manual Audit: We combine high-precision robotic assembly for consistency with meticulous manual audits for aesthetic perfection.

3. Aging Test: Every headlight undergoes a mandatory 4-8 hour continuous burn-in test in our aging room to eliminate early-life failures.

4. Waterproof Vacuum Test: We utilize advanced air-leakage testing equipment to ensure every housing achieves an IP67 or IP68 waterproof rating.

3. Advanced Testing Equipment

To guarantee "Zero Defect" performance, our laboratory is equipped with state-of-the-art testing instruments that simulate the harshest road conditions:

1. Goniophotometer System: Measures light distribution, beam patterns, and luminous flux to ensure full compliance with DOT, ECE, and SAE standards.

2. Salt Spray Test Chamber: Simulates harsh coastal and winter environments to test the anti-corrosion properties of all metal and plastic components.

3. High/Low Temperature Chamber: Tests structural integrity and electronic stability under extreme thermal stress, ranging from -40°C to +105°C.

4. Waterproof & Humidity Testing Station: Validates the seal against heavy rain, high-pressure washing, and tropical humidity levels.

Our Promise: Every light that bears the name of Guangzhou Xinyi Photoelectric Technology Co., Ltd. is a beacon of safety and reliability. We don't just sell headlights; we provide peace of mind for the road ahead.
