Uniformity analysis of Temperature Distribution in the grating embossing mold by Induction Heating

摘要：

　　In order to obtain uniform temperature distribution in an embossing mold heated by induction used for replica of plastic gratings,temperature fields in the mold are analzed by using electromagnetic-thermal coupling field of ANSYS software.The results indicate that the air gap between the induction heating coils and heating element,and the coils current density,have a great influence on the temperature distribution,while the exciting frequency had little.When an exciting current of 1636A*N,frequency 25KHz and heating time as 70 seconds,the optimal air gap width is of 4 to 5 mm.At the same time,reduce the exciting current densities can improve temperature uniformity on mold surface.
