Mr. Chen, the R&D director of a high-end car manufacturer, once paid a heavy price due to the distortion of material testing: "The car exterior coating we developed has a weather resistance life of 15 years in laboratory tests, but it turned yellow and cracked just 8 years after actual installation, causing 12 projects across the country to have to be reworked and resulting in losses of over 120 million yuan." It was only after the fact that it was discovered that the spectrum of the traditional simulator could not match the actual outdoor light at all, especially the energy deviation in the ultraviolet band was large, and it was impossible to accurately predict the aging trend of materials, which was equivalent to making a mistake from the source.
Saifan Optoelectronics' automotive-specific solar simulator has specifically addressed this industry pain point. The device is equipped with a dedicated spectral library for automotive materials, specifically optimizing the energy proportion of the 300-400nm ultraviolet band - this band is precisely the key factor affecting the weather resistance of automotive exterior materials. The spectral matching degree has soared to 98.5%, and the consistency with the actual outdoor lighting conditions exceeds 96%. Equipped with environmental simulation modules for high and low temperatures, humidity, and rain, it can comprehensively reproduce the complex outdoor climate conditions. It can continuously conduct extreme weather resistance tests for 5,000 to 20,000 hours. The consistency between the test data and the actual outdoor service life exceeds 95%, accurately predicting the actual service life of materials and avoiding quality risks from the source.
"After introducing Saifan's simulator, the accuracy rate of our exterior material testing has increased to over 98%, and there have been no more rework issues!" " Engineer Chen stated, "The operating noise of the equipment is ≤55dB, and its energy consumption is 45% lower than that of traditional equipment, saving over 200,000 yuan in annual electricity bills." Moreover, it can simultaneously test multiple component samples, increasing the testing efficiency by three times and significantly shortening the R&D cycle. Now this device has become a must-pass inspection checkpoint for us before mass production, providing a core guarantee for the stability of product quality.
