光陽鋳造所 Company Profile

For pure copper, copper alloy casting, and machining, please leave it to Koyo Casting Co., Ltd.!

At Koyo Casting Co., we primarily engage in casting copper products. In particular, our pure copper casting technology is one of the few in Japan and is highly valued by various manufacturers. We handle everything from casting to machining, and, if necessary, pressure testing as well. In recent years, we have been focusing on casting (with processing) in China to respond to globalization.
