Since we need to find new materials for our new project development, we have contacted Xinhejiu for a long time. After many communications between both parties, we have jointly confirmed the product performance requirements and developed samples for application. At the beginning, I was not satisfied with the application, and the finished products were defective. Therefore, xinhejiu sent engineers to the factory to watch the production application, and gave guidance to our company on dust removal measures on site. After that, the thickness of the product protective film was adjusted, and the product defects in the application process were successfully solved. The subsequent samples are applicable to all normal conditions, and the new product development of our company is also carried out smoothly.
