The design starts in a CAD environment with the modeling of the components to be embedded and the design of the part.
A technique used to embed components involves the use of “spacers” or fixtures. These are manufactured with the same interface. The spacers are used to locate the components in the part and to selectively encase different parts of the components in different materials by acting as a dam or separator.
Figure 2. Close up of design of embedded components (above). A technique used to embed components involves the use of spacer or fixtures (below). The picture (below left) shows the spacers for the pneumatic piston. The spacers are used to locate the part and to separate different materials. For example, we want to cast part material around the body of the piston, but we want to cast support (sacrificial) material at either end of it.
