Abstract

A cold flake suppression method is provided. A molding device includes a sleeve, a tip, a sprue guide portion, a molding die, a sprue ring, a distributer, and a control device. The sprue guide portion includes a stamp portion, a runner portion, and a gate portion. The control device drives a supply device to slide the tip for molten metal to flow through the sleeve; sequentially calculates an amount of heat transfer changing continuously from the start of supply of molten metal until the tip slides to the position in FIG., and calculates a total of the amounts as a total amount of heat transfer; and calculates a volume of the sprue guide portion based on information about the sprue guide portion input by an operator. Shapes of the sleeve and the sprue guide portion are determined to set a cold flake index equal to or less than 0.842.
