Molds Design Introduction

In this lesson, you create a mold tooling for a telephone handset.

You start with a model of a telephone handset. Before creating the mold tooling, you add mounting bosses to the model. This demonstrates the fastening features commonly used on molded products.

Then you create the mold, which is composed of a core and cavity. The core duplicates the inner surface of the model, and the cavity duplicates the outer surface of the model. A parting surface divides the core from the cavity.

To manufacture the telephone handset, the core and cavity are joined together, and liquid plastic or metal is injected to fill the open areas between the core and the cavity. After the liquid cools and solidifies, the core and cavity are separated, and the part is ejected. Before you create the core and cavity, you prepare the model using the tools listed below, to ensure that the part will eject properly.
