Special fund of the scientific research institute of the Ministry of Science and Technology of the People's Republic of China "Research on the application of high-quality automatic brazing series solder paste preparation technology".
The multiform product types, such as powder, paste, wire and sheet, meet the requirements for brazing and assembly of various complex workpieces, and are applicable to different brazing processes such as flame welding, high-frequency induction brazing and shielded atmosphere furnace welding. Over the years, the in-depth research and development and application of new materials and new processes have led to the continuous improvement of brazing technology in the industry, promoting the transformation and upgrading of industrial manufacturing technology to intelligent and green.
Mainly used in: paste solder product line
Paste solder products are a new type of welding materials independently developed on the basis of powder solder through interdisciplinary research. It has a wide range of applications and simple operation process, and can replace powder or solid solder in many fields. Its research and development cycle is long, its technology content is high, and its manufacturing process is complex, which plays a key role in the enterprise's automatic production.
