Daily Inspections Empower the Pursuit of Premium Quality

Each batch on every production line undergoes a rigorous series of daily inspections, covering full-process quality monitoring from raw material incoming to finished product delivery. The tests are performed using our advanced testing equipment, including Enameled Wire Thermal Endurance Class Precision Tester, Voltage Breakdown Tester, Enameled Wire Outer Diameter (OD) Tester, Enameled Wire DC Resistance Tester, Computerized Universal Testing Machine, ZGQ-16B Automatic High-Voltage Enamel Continuity Tester, ZHX-L Solderability Tester, ZDG-25 Intelligent Unidirectional Paint Scraping Tester, and QJ57 Type DC Resistance Bridge.

The detection process follows a strict three-stage protocol: first, 100% incoming inspection of copper and Aluminum Wire raw materials to verify purity and dimensional accuracy; second, in-process sampling tests every 2 hours during enameled wire production, focusing on enamel thickness, continuity, and solderability; third, final batch inspection for each finished product, which includes thermal endurance class verification, dielectric loss measurement, wire diameter precision calibration, and tensile strength testing. Our Enameled Wire Thermal Endurance Class Precision Tester, recognized as the most accurate in the industry, ensures thermal performance data meets IEC 60317 and ASTM D230 standards. Meanwhile, the high-precision Enameled Wire OD Tester guarantees wire diameter tolerance within ±0.001mm, exceeding customer-specific requirements.

At our factory, quality is not just a standard but an uncompromising commitment. We implement a zero-defect quality control system, where every test result is digitally recorded and traceable for 5 years. Our quality team consists of certified engineers with over 10 years of experience in enameled wire testing, and all equipment undergoes annual calibration by authorized third-party institutions to maintain measurement accuracy. We also proactively exceed international standards by incorporating additional tests such as solvent resistance, rebound angle measurement, and sudden tensile break testing, ensuring our products withstand the most demanding industrial applications. For us, precision in every detail and dedication to quality excellence are the foundations of our long-term partnerships with global clients.
