Quality Policy
TEST CENTER
PRODUCT TESTING LABORATORY
Our state-of-the-art laboratory is the heart of our quality assurance. We conduct a wide range of evaluations, including product weathering tests, mechanical performance analysis, and physical/chemical experiments . These tests ensure that every component we produce can withstand the most challenging environments, such as industrial enclosures and control panels.
TEST EQUIPMENT
INSPECTION EQUIPMENT
To maintain uncompromising standards, we utilize a comprehensive suite of professional instruments:
- Environmental Simulation : Using our Salt Spray Test Machine, UV Weathering Chamber, and Waterproof Testing Machine, we simulate extreme weather conditions to ensure hardware durability in outdoor or harsh industrial environments.
- Precision Measurement & Analysis : Equipped with Image Measuring Instruments and Hardness Testers, we maintain strict dimensional accuracy and material integrity for every component.
- Safety & Performance Verification : Our High Voltage Testers and Impact Testing Machines verify the electrical safety and mechanical strength required for critical equipment housings and control panels.
- Automated Durability Testing : Through our Lock Life Test Machines, we perform rigorous repeated-cycle evaluations to guarantee the long-term reliability of hinges and latches.

Composition Analysis of material
Quality starts with the right foundation. Our quality management department uses professional spectrometers and high-speed analyzers to perform scientific analysis on all raw materials . This ensures that every batch meets our strict performance standards and material specifications before production begins.
Life Cycle Test
We verify the long-term durability and consistent performance of our products through rigorous life cycle testing . By simulating thousands of repeated operation cycles, we ensure that our hardware—such as the MS-719 series and custom paddle latches—maintains smooth operation and stable mechanical performance throughout its extended service life, even in demanding applications like EV chargers and energy storage systems (ESS).
