Abstract
The invention relates to a method for manufacturing a shoe part by injection molding a material into a mold where an insert is placed. The insert comprises at least two separable insert parts, an upper insert part and a lower insert part, providing an injection channel in the region of the separation area between the two parts. The insert is placed in the chamber and the injection material is injected through a sprue channel in the mold into the injection channel and into a cavity, whereby the shoe part is formed. The mold is opened after the injection material has cured and the insert is separated into the upper and lower insert parts, thereby exposing the cured material in the injection channel.
