Accurate and complex casts in one day
Koiwai has been devoted to manufacturing foundry parts for over 40 years. Until they introduced 3D printers in 2007, they mainly used wooden molds for casting. It takes about 10 days to complete the casting with this manufacturing method, because it is necessary to manufacture a sand mold after completing the wooden mold, which requires a machining tool and manual labor from a craftsman.
When customers asked for sand molds with high precision and complex shapes in a short time, Koiwai decided to incorporate 3D Printing into their casting business and as a result they greatly changed their industry practice. With 3D Printing and advanced data preparation software, Koiwai can directly form the data, so the casting is achieved without labor-intensive wooden molds. As a result, the construction period was shortened to one tenth of the time the original wood construction method took. Furthermore, by using 3D Printing, it is possible to produce sand molds of complicated shapes which were difficult to produce before.
