Abstract: CGI cylinder block and cylinder head foundry process was introduced in this paper. The CGI production process which combine wire feed technology and thermal analysis was studied in this paper. This process has the advantage of wire feed's precise control and this process can give anticipation of the iron through thermal analysis which can assure the result of treatment. This process can be used in mass production of CGI cylinder block and cylinder head. The problems during CGI production were analysed meanwhile,relevant methods were given.
Keywords: CGI; cylinder block; cylinder head; foundry process
