The next stage in stack turning technology is the use of a cube system. The mold core rotating in 90° steps enables several production steps to be performed simultaneously. The extreme flexibility of this process results in higher production performance with significantly shorter cycle times.

A special version of stack cube technology is In-Mold-Assembling (IMA). In this process the four stations of the cube are utilized in a specific sequence. Two different parts are molded simultaneously in Station #1. Very high-precision assembly, both inside and outside the system, can be performed in Station #2. The parts are overmolded in Station #3, and removed or ejected at Station #4.
