“…S. C. Chen et al [2][3][4][5][6][7] have investigated induction heating with experiments and simulations on weld lines and their strengths, micro-features with high aspect ratio, comparing with electrical heaters, and pulsed cooling. Overall conclusions were induction heating had faster heating, using multiturn coil gives better temperature uniformity and that induction heating does improve the filling of micro features/cavities and weld lines strength, as well as their visual appearance.…”

Rapid mold heating has been recent issue to enable the injection molding of thin-walled parts or micro/nano structures. High-frequency induction is an efficient way to heat mold surface by electromagnetic induction in a noncontact manner, and has been recently applied to the injection molding due to its capability of rapid heating and cooling of mold surface. The present study covers a three-dimensional finite element analysis to investigate heating efficiency and structural safety of the induction heating process of an injection mold. To simulate the induction heating process, an integrated simulation method is proposed by effectively connecting an electromagnetic field analysis, a transient heat transfer analysis and a thermal stress analysis. The estimated temperature changes are compared with experimental measurements for various types of induction coil, from which heating efficiency according to the coil shape is discussed. The resulting thermal stress distributions of the mold plate for various types of induction coils are also evaluated and discussed in terms of the structural safety.

“…Meanwhile, only a few studies on plate forming with the induction heating process have ever been reported. The 2-dimensional temperature distribution during high-frequency induction heating has been the main subject in most of these studies [2][3][4][5][6], and the 3-dimensional deformation behavior of a steel plate has been modeled by an analytical method [7]. Nevertheless, the previous study gives finite element method (FEM) models for analysis of the heat-flux, heat-flow, and thermo-mechanical behaviors in the steel forming process with induction heating [8].…”

To control a heat source easily in the forming process of steel plate with heating, the electro-magnetic induction process has been used as a substitute of the flame heating process. However, only few studies have analyzed the deformation of a workpiece in the induction heating process by using a mathematical model. This is mainly due to the difficulty of modeling the heat flux from the inductor traveling on the conductive plate during the induction process. In this study, the heat flux distribution over a steel plate during the induction process is first analyzed by a numerical method with the assumption that the process is in a quasi-stationary state around the inductor and also that the heat flux itself greatly depends on the temperature of the workpiece. With the heat flux, heat flow and thermo-mechanical analyses on the plate to obtain deformations during the heating process are then performed with a commercial FEM program for 34 combinations of heating parameters. An artificial neural network is proposed to build a simplified relationship between deformations and heating parameters that can be easily utilized to predict deformations of steel plate with a wide range of heating parameters in the heating process. After its architecture is optimized, the artificial neural network is trained with the deformations obtained from the FEM analyses as outputs and the related heating parameters as inputs. The predicted outputs from the neural network are compared with those of the experiments and the numerical results. They are in good agreement.
