Impro CGI Sand Casting capabilities
CGI stands for Compacted Graphite Iron, also known as vermicular graphite iron in non-English-speaking countries. It is a metal widely used in applications that require either greater strength or lower weight than cast iron. CGI has been used for brake discs on high-speed rail trains, diesel engine blocks, cylinder heads, turbo housings, and exhaust manifolds.
Impro supply CGI sand castings mainly for engine cylinder heads on marine vessels, with weights ranging from 40kgs to 300kgs.
CGI Grade: CGI-350; CGI-400; CGI-450
Impro CGI Equipment and Technology: SinterCast System 3000 and SinterCast System 4000.
We can steadily achieve over 90% vermicular graphite.
