Product Description
Purpose of thermal shock test
Three box-type of hot and cold impact test machine is to test thermal expansion and contraction of products caused by chemical changes or physical harm, to put the material structure or composite material in an industry under conditions like extremely high temperatures and very low temperature. It is an ideal test machines in detecting electronic components, metal, chemical materials, national defense industry, aerospace industry, BGA, PCB board, IC, semi - conductive ceramics, etc.
