Clamping daylight opening

Stack mold also features two or more daylights in the open position. Two daylights are the normal form (Figure 17.5) but up to four are also used more could be used. The purpose of the stack mold is to increase the number of cavities in the mold without increasing the projected area so the clamp force required from the IMM remains the same. Similar cavities and cores between each of the daylights are normally used.
