MCCB Highlights
Advantages and highlights of welding process equipment for MCCB Electronic type hardware parts
1. Acereare has strong welding core competitiveness,
and uses fully automatic equipment to flexibly accept parts welding
processes from all walks of life.
2. The welding process shall be standardized. Standardized electrode processing, standardized electrode use, standardized electrode maintenance and standardized data management completely solve the problem of unstable welding process
It has a number of key process technologies. Such as indirect heating resistance brazing process, induction brazing process and automatic welding after grinding (for welding problems of different materials).
3. The infrared temperature control technology is used to precisely control the welding parameters, which ensures the welding quality and greatly improves the service life of the product by 50%.
