Supplier Information
Chengdu Nanguang Machinery Co., Ltd. is one of the manufacturers in China's vacuum equipment industry and special equipment for the electronics industry. Its predecessor can be traced back to the Sichuan Machinery Bureau founded in 1877. After a century of vicissitudes, the company has now developed into a high-tech enterprise dedicated to the research, development, production, and sales of vacuum equipment.
The company's products mainly cover two categories: vacuum acquisition equipment represented by vacuum pumps and vacuum systems, and vacuum application equipment represented by vacuum coating machines and vacuum industrial furnaces.
In 1958, the company entered the field of vacuum equipment and began to develop vacuum acquisition equipment; in 1964, the company successfully developed China's first vacuum coating machine; after more than 60 years of development, it has become one of the enterprises with a long history, complete varieties, and a comprehensive technical system in the domestic vacuum equipment field. It is also a vacuum technology solution provider with comprehensive research and development capabilities for both vacuum acquisition equipment and vacuum application equipment in China.
