The invention relates to a method for engraving heel lifts. The method comprises the following steps of: pre-embedding the heads of lift nails into a heel-lift die cavity at certain intervals; respectively successively injecting or filling two or more types of mixtures different in strength, hardness and color into the die cavity by adopting two or more injection molding machines or filling machines so as to manufacture a single blank or a whole piece of blank plate; and then, engraving lifts into required shapes and sizes by using an engraving machine. The hardness and strength of a manufactured heel lift are good, and the heel lift can be articulated with a lift nail more firmly so as to prevent the heel lift from separating from the lift nail; the bottom layer of the heel lift is made of materials which are good in anticorrosive performance and flexibility, thereby improving the abrasion resistance and comfortableness of the heel lift; and through adding pigments of different colors, heel lifts with multiple types of different color combinations can be produced, thereby increasing the aesthetic property of the heel lift, enriching heel products and satisfying the favors of women. When a small batch of many types of heel lifts are produced, the method does not need to adopt many molds; and when a large batch of heel lifts are produced, the number of molds can be increased.
