Cube Molds


Production of highly complex parts on a single machine

With the FOBOHA stack-turning technology, parts are processed within the turning system at different levels. So it is possible to inject parts on both levels in the same production step and eject the finished parts at the available station. The next turn (2 x 180° or 4 x 90°) moves the new substrates to the newly freed processing station.

Advantages of the stack-turning technology:

  • Highly complex parts can be produced on a single machine
  • The clamping force of the machine can be halved
  • Cavities can be doubled
  • Production cycles are significantly shorter

FOBOHA Cube technology
The core of the mold rotates in 90° steps, enabling multiple production steps to be carried out simultaneously. The high variability of this process offers higher production performance with significantly shorter cycles.

In-mold-assembly (IMA) is a special variant of the cube technology. In this technique, the four stations of the cube are used in a special sequence. Two different parts are injected at the same time at station 1. At station 2, high-precision assembly can be carried out both within and outside the system. The parts are overmolded at station 3, then removed or ejected at station 4.

FOBOHA Double Cube Technology
The innovative FOBOHA Double Cube System combines two synchronized counter-rotating cubes between the two halves of the mold. In principle, two separate molds operate within a single piece of equipment. Simultaneous work processes take place at three parting lines in 90° steps. A specially developed drive and coordinating mechanism allows the two cubes to be opened and closed within a very narrow space. Optionally, a second injection unit can ride the clamping unit. Flexible device adaptations on the ejection side round out the production options.

The FOBOHA Double Cube System offers a previously unheard of efficiency in multicomponent injection molding technology and makes a number of new
production processes possible:

  • Concurrent injection processes in the cavities of two parting lines
  • Reduced cycle times
  • Simultaneous options such as label insertion, assembly of various injection molded parts, removal and ejection of finished parts
