In the past twenty or thirty years, the progress of iron sand technology and the development trend of the future are mainly as follows:  

1. The optimization of conventional sand blasting process iron sand process, keep the original process principle unchanged, by improving the process premise, optimize the process parameters to achieve.  

2. The development of new processing methods, the introduction of new energy, the application of new materials, and the requirements of special functions of products all promote the formation and development of new processing methods, such as laser processing technology, electromagnetic processing technology, superplastic processing technology and composite processing technology.  

3 professional, disciplinary boundaries gradually fade, disappear, in the sandblasting process iron sand technology internal hot and cold processing, processing process, testing process, logistics process, assembly process, design, material application, processing sand blasting process iron sand, its boundaries are gradually fade, gradually toward integration.
