Cube-mold technology at its best: inject two components and then rotate the cube halves in opposite directions like a Rubik's Cube. Then assemble 24 components simultaneously in the mold: Foboha's Reverse Cube system for the ALLROUNDER CUBE, automated with a six-axis robot, can do just that.
Sophisticated cube-mold technology: up to 40% less cycle time than with two separate injection molding machines and assembly.
The turnkey system with ALLROUNDER CUBE 2900 and six-axis robot produces ready-to-install lower basket rollers for dishwashers.
A single cube machine replaces three machines including assembly systems, saving a huge amount of money and space.
“By exchanging ideas with competent partners, we always find fantastic technical solutions, such as the Reverse Cube cube-mold technology.”
Rainer Armbruster, Managing Director of Foboha
Hermann Hauff was already producing two-component rollers for the lower baskets of BSH dishwashers. Each molded part consists of a socket made of PP and rollers made of POM. A new product variant and the expansion of the annual volume by around 20% meant that a new, more efficient solution had to be found.
The Reverse Cube system with a 24+24-cavity mold and the ALLROUNDER CUBE with a clamping force of 2,900 kN are precisely coordinated with and adapted to each other in terms of software, automation and QA evaluation, for example. While the PP bushings are molded on the lower half of the cube, the corresponding POM rollers are created opposite on the top. The cube halves then rotate 90° in opposing directions. On the passive cube sides, the molded parts cool down to such an extent that the individual parts can be assembled directly in the mold. This task is performed by a six-axis robot integrated into the control system at the rear of the machine without affecting cycle time. Process monitoring and 100 percent parts inspection are automated.
“Together we have shown how an extraordinary tool idea from Foboha translates into commercial success. ”
Jörg Vetter, Technical Director at Hermann Hauff
Originally, cube-mold technology was mainly used in the packaging sector, but it is now finding its way into more and more new areas of application. This is because high volumes are also sometimes achieved in areas such as medical technology, health care and technical parts. An automated packaging station can be added to the existing turnkey system for lower basket rollers, and the entire process up to the deliverable product can be carried out automatically.
From building technology to mechanical engineering: a broad spectrum – and ARBURG is always your partner. Because you want to produce economically, effectively and flawlessly. And fast.
