Internal sliders

Internal undercuts can be found when the inside of the molded part has projections which will hinder the part to get removed from the mold. Internal splits (Figure 1.19), internal sliders which are externally operated and inclined segments (which are used in collapsing cores. Figure 1.19 on the right) can be used.

Figure 6.70 shows choosing system of units in Mathcad Prime. Only three of them are now available international system of units (SI), the system of units customary in the US (USCS) and centimeter-gram-second system (CGS), conventional for a number of physical calculations. It is impossible to disable units in Mathcad Prime (see slider None in Fig. 6.69)...
