The advantage of the cube technology over other mold technologies is that the number of cavities for the same machine size can be doubled. Or in other words: for the same production lot, the size of the machine is almost halved.
In the stack turning technology, the mold rotation is performed with a horizontal rotary device in the form of a center plate. Plastic parts are produced in the first parting plane. When the mold is opened, they remain on the side of the moving center plate. For a fully opened mold, the center plate is rotated 180° and placed in the second parting plane. After closing again, the second component is injected in the second cavity where the parts are located on the center block.
When using stack-turning molds with 4 × 90° rotation, stations 2 (operator side) and 4 (non-operator side) can be simultaneously used for further production steps.
For example, station 2 can be used for cooling the molded parts and station 4 can be used for removal by a robotic system. Both functions take place without affecting the cycle time. Alternatively, station 2 can also be used for mounting (in-mold assembly) inside and outside the system.
