Russia-this is a customer with a long history. In the former Soviet Union, they were Russian manufacturers of silicon carbide heaters. After the disintegration of the Soviet Union, production could not be resumed for a long time, but the demand for silicon carbide heaters was great. In 2010, they came to China to find suppliers. After many inquiries, they chose to use our products. Customers are very interested in our products. After conducting a series of tests in Russia, they finally decided to cooperate with us. For ten years, we have always put forward higher requirements for quality!
