Technology / product information

We specialize in lost foam casting to manufacture complex-shaped components made from gray cast iron (FC) and ductile cast iron (FCD) with high precision and consistent quality. Some parts achieve such accuracy that secondary machining becomes unnecessary, significantly improving productivity and reducing costs.
Lost foam casting is a technique that uses foam patterns to accurately cast even the most intricate shapes. By utilizing equipment from Taiyo Machinery and foam patterns from Taniguchi Chemical Industry, we achieve high-quality casting for both gray and ductile iron. With its smooth surface finish, lost foam casting minimizes the need for secondary processing, contributing to cost savings.
