International trade and international cooperation


For more than a century, the cooperation between Nan Guang and the world has never been interrupted. Since 1877, Nan Guang has been growing by learning advanced Western technologies; in the 1950s, the company quickly established a solid technical foundation for a modern industrial enterprise by learning and exchanging with the former Soviet Union; after the reform and opening up, Nan Guang opened its arms to the world, not only exporting some of its products to Japan, South Korea, the United States, North Korea, Poland, India, Australia, Pakistan, Singapore and other countries, but also conducting technical cooperation with Japanese companies such as Toshiba, Asahi Glass, NEG, American Corning, Swiss Balczars, and Hong Kong Kangda, providing domestic and foreign users with process equipment of international standards.


国际贸易与国际合作


一个多世纪以来,南光和世界的合作从未中断过。从1877年开始,南光一直在学习西方先进科学技术中成长;20世纪五十年代, 公司通过向前苏联学习和交流,迅速奠定了现代化工业企业的坚实技术基础;改革开放后的南光更向世界敞开了怀抱,不仅部分产品出口到日本、韩国、美国、朝鲜、波兰、印度、澳大利亚、巴基斯坦、新加坡等国,还和日本东芝、旭硝子、NEG、美国康宁、 瑞士巴尔采斯、香港康大等公司进行技术合作,为国内外用户提供具有国际水平的工艺设备。 


Develop in sync with the world


Since the company obtained the right to handle imports and exports independently in 1997, the communication between Nan Guang and the world has become even closer.


The company has carried out multiple technological collaborations.
