Injection molding of shoe soles with foamable and crosslinked EVA base compounds

摘要

The present invention relates to a method of injection molding shoe soles of foamable and crosslinked "EVA" based compounds, which prevents spontaneous shrinkage of the sole by means of a template consisting of a rigid plate placed on the sole during the molded sole cooling step. Characterized in that the edge of the template is connected with the raised peripheral edge on the upper surface of the sole and the sole size is no longer reduced during or after the remaining cooling stage.
