|Longevity of the Mold|
|Thermoplastic Resin||Number of Shots|
|Investment Casting Wax||1000-10000|
|Nylon (filled with glass fiber)||300-3000|
Since the consistency of the mold is hard, it cannot be distorted to ensure part release. Therefore, elimination of undercuts and the implementation of draft is necessary, as shown in the figure below. As can be seen in the figure, much detail is lost because of the need to make a non-distorting tool that releases the part.

The following figure shows the completed lay up assembly for the top half of the mold.
