Tasks and Modes of Operation

To clarify the tasks and functions of an injection mold, it is best to follow the path of the material within the injection molding machine aU the way to the development of the finished article. The material has been conveyed into the injection chamber during the course of the plasticating phase. Along the way it has been melted and homogenized. 

The prepared, flowable material is transported from the injection chamber of the plasticating and injection unit into the mold. In other words, it is injection molded.  

The impression space into which the molding compound is injected-known as cavity-is located within the mold. The material solidifies by cooling within the cavity, thus forming the molding. With thermosets/elastomers, the article is produced by chemical crosshnking reaction. 

Each cycle of the injection molding process often produces only one molding. 

In this case, we speak of a single-impression mold .
