Abstract
A method of manufacturing a multicolor shoe material includes the following steps. Step S1: blank molds are provided, and a mold chamber of each of the blank molds is injected by one of the foamed materials in different colors to form unfoamed semi-finished products in different colors. Step S2: the semi-finished products are put into a foaming mold, when the foaming mold is preheated and completely closed, a ratio of a total volume of the semi-finished products to a volume of the mold chamber of the foaming mold is ranged between 0.96 and 1.04. Thus, the semi-finished products could be evenly foamed. After foaming, adjacent two of the semi-finished products could be connected by heat fusion to obtain the multicolor shoe material. Additionally, a semi-finished product and a multicolor shoe material are provided in the present invention.
