Johnson screen surface treatment
Generally, the finished product will be polished, so that the product will appear bright.
With China’s emphasis on environmental protection, this treatment process has been banned. We independently developed a new treatment process to physically treat the product surface, which not only has a smooth appearance but also greatly improves the service life of the product.
