Research and Development
Gonda Metal is not only making efforts to the improvement of the present products but also to the development of a new product for the next generation. We are dealing with the research and development of the next product by the theoretical proof with co-research with universities and laboratories.
Introduction of the research result
Results of "Development of Copper Deformed Bar by Conform Extruder"
Gonda Metal has succeeded in developing a continuous extrusion molding process for copper deformed bars, thereby making them commercialized. Extrusion by Conform has, in theory, no limitation to extrusion length and can produce shapes that are very close to those of final products. Even deformed shapes as shown in the photo can be extruded in one operation, and fine microstructure and high workability can also be obtained.
Result of the development of mass-production for magnesium alloy sheet by the hi-speed twin-roll casting system and hot rolling
Magnesium and its alloy are the lightest metal in all metals of practical use and have various useful properties. We have begun to study a new twin-roll casting system which can cast the magnesium alloy sheet directly cooperating with professors of universities since 2002.
As the result, we have successfully developed a new hi-speed twin-roll casting system named "Gonda Twin-roll Casting System" (GTC) and obtained the patent. Various magnesium alloy sheets, which have generally been recognized it is difficult to manufacture magnesium alloy sheets excepting AZ31, can be manufactured by GTRC. GTRC can manufacture various magnesium alloys
such as AZ31, AZ61, AZ91, AM50, AM60 and so on. We are going to study other magnesium alloys except them in the future. In 2008, the mass-production for AZ61 which is excellent in press workability, strength and surface treatment has been started.
Explation on Gonda Twin-roll Casting（GTRC)
Gonda Metal has developed a new twin-roll casting system(GTRC: Gonda Twin-roll Casting System) to manufacture the magnesium alloy sheet. Not only AZ31 sheet, but magnesium alloy sheets made from AZ61, AZ91, AM50, AM60 and so on can be manufactured of which it has been recognized as difficult to manufacture, by combinig this system GTRC and rolling process.
