Latest Patents

Yaekura holds a patent for a method of hot stamping galvanized steel sheets. This patent describes a process where the change in emissivity of the surface of a galvanized steel sheet is measured in a temperature range lower than the boiling point of zinc but not lower than the ferrite transformation temperature. The method utilizes an emissivity sensor with an observation wavelength of 1.4 μm or longer. The pressing and quenching process is initiated after detecting the completion of an alloying reaction based on the change in emissivity. The emissivity sensor preferably employs an InGaAs element or a thermopile as a measuring element.
