A Method of Controlling MTC Solidification Process by Cooling Threshold
A method of controlling Mold Temperature Control (MTC) solidification process by cooling threshold was presented based on Finite Element Method (FEM) simulation and experiments research. The outcome provides a basis for selecting MTC parameters. The 3D transient heat transfer analysis was done in various conditions which include the cooling threshold of 500, 20, 400, 440, and 300℃ respectively. The study results indicated that the cooling thresholds influence the forming process greatly for directly controlling the opening of channels. If the threshold is big beyond the mold preheated temperature, all channels will be opened at the beginning of the process, and the workpiece will be solidified rapidly, but the forming quality is worsened because of the shrinkage cavity. Contrarily, when the threshold is small extremely, cooling channels cant be opened in time, the forming efficiency will be decreased.
