■Core Competence

Lightweight, inexpensive, and clean bronze castings by a Decompressed and Frozen Mold Casting system
A thin wall and lightweight bronze casting process has succeeded by using a Decompressed and Frozen Mold Casting system for the first time in the world. This breakthrough casting technologies have reduced a 20% of the raw material cost and the melting energy and more than 90% of the casting sands and shells' industrial wastes as well as suppressing offensive odors, vibrations, noise, and dust particles. In domestic market, our manufacturing processing therefore has been changed to such that thin and lightweight complicated large bronze castings have been fabricated by a five-axis machine or machined in a machining center. Large production bronze products are cast, fabricated, and assembled in Dalian, China, in where Dalian plant has many automated and labor saving facilities, which is authenticated as a JIS Mark plant.
