Integrated Production System at KOBAYASHI CASTING
In-House Post-Casting Machining
We not only specialize in lost wax casting but are also fully equipped for high-precision post-casting machining on-site. With machines such as vertical milling, horizontal milling, surface grinding, and CNC machining centers, we can meet tight tolerances up to ±0.01mm. Even thin-walled or complex-shaped parts can be handled flexibly and efficiently thanks to our integrated system, ensuring stable quality and prompt delivery.
