Our factory production control (FPC) system complies with ISO 9001 standards, guaranteeing full traceability.
Let's grow together
Our partnership reflects unwavering dedication to precision and excellence, embodying the core values.
Rigorous validation includes:• Sample Selection: Representative test specimens are randomly drawn from routine production in accordance with standard sampling protocols to ensure compliance with ongoing production quality.• Mechanical durability test exceeding 500,000 cycles• Closing overload test• Salt spray test• High and Low Temperature Test: Unlike non-standardized methods where samples are passively placed in refrigeration units, our testing environment actively simulates operational conditions, ensuring accuracy, repeatability, and alignment with CE, UL and ANSI testing procedures.
Additional Mechanical Testing:The test center performs supplementary evaluations using calibrated equipment, including gear engagement (teeth) testing, material hardness testing, spring performance testing, and surface roughness measurement, in accordance with applicable CE, UL and ANSI standards.
In-House Testing Laboratory
We operate an advanced in-house laboratory with testing equipment aligned with European and North American standards.
Certified Product Excellence
All products meet international certification requirements. Global certifications include CE, CERTIFIRE®, UL, and ANSI.
