We own the production environment with one hundred thousand grade purification and also have the matched cleaning room. The well air supply exhaust system guarantees the quartz products free from environmental pollution. So the products will have a good appearance for customers. For the product size control, we developed a variety of high-purity graphite mold to ensure the accuracy of product size.
