Castings have excellent mechanical and physical properties,it can have a variety of different strength,hardness,toughness with comprehensive performance,can also with one or more special performance,such as wear resistance,high temperature and low temperature resistance,corrosion resistance,etc.
Vacuum impregnation were solved by use of hot water solidified porous sealant technology in foundry industry has long vexed problem. Less equipment investment,simple operation,quick,high reliability (an impregnation rate more than 98%). The can make the design of thin-walled parts,and can withstand high pressure parts to burst,it need to rework the recasting of the scale to zero,comprehensive comparison,than use other process greatly reduces the production cost. At home,especially a motor vehicle manufacturing industry of T88,T90 demand increased rapidly,mainly for the regulator,carburetor,automatic gearbox shell,motor vehicle cylinder block,cylinder head,crankcase,the compressor shell,etc.
With the development and application of the technology,is widely applied to various fields of industrial production.
