Our R&D center drives innovation through bespoke formulas, precision color matching, and reverse engineering. We meet your exact specifications while guaranteeing peak performance and consistent quality, even under extreme conditions.
Our advanced lab delivers precise color synchronization across hundreds of hues. From metallic and matte to unique custom shades, we provide high-fidelity samples with a rapid turnaround.
We offer end-to-end R&D—from raw material selection to lab validation. We help partners develop "exclusive formulas" tailored for specific performance and extreme durability.
Using high-precision analysis, we deconstruct and replicate existing market products. We help you achieve technical breakthroughs and cost optimization with equivalent or superior performance.
Equipped with a multi-axis loading system, it can conduct various mechanical tests such as tension and compression. The measurement range covers from 0.01 MPa to 10 GPa, with an accuracy of ±5%.
Standardized testing methods and millisecond-level timing accuracy provide reliable data support for the operational time and extrusion performance of the product.
A controlled ageing environment with three-dimensional regulation of temperature, humidity and light exposure, capable of simulating over ten years of natural ageing processes to evaluate materials’ resistance to ultraviolet radiation, oxidation and hydrolysis.
Achieving temperatures ranging from 150°C to 1300°C and beyond, meeting the high-temperature testing requirements for diverse products to evaluate material performance changes following exposure to elevated temperatures.
Temperature range from -40°C to +150°C, humidity from 0% to 100% RH, accuracy ±1°C/±0.5% RH, supporting extended environmental cycling ageing.
Accelerates chemical and physical ageing processes, enabling natural ageing that would typically take thousands of hours to be completed within tens to hundreds of hours, thereby shortening research and development and testing cycles.
We ensure superior quality stability and batch-to-batch consistency through our automated production systems, stringent multi-stage quality control, and continuous post-delivery performance monitoring.
