This mold is built for a machine specially equipped for stack molds. The side of the center section has provisions to mount the center section to the machine supports. Cycle time 6 s no MO time productivity 9 600 pieces h. Notable advantages of stack molds are as follows For the same output there is only about one half of the plant space required compared with two machines making the same product on single-level molds. The same clamp size can be used for twice the number of cavities. In fact it is required to have about 10 more clamping force than for a similar one-level mold as explained 5 . However it is important that the machine has at least twice the shot capacity than that required for a single 148 4 Mold Selection Figure .
