Lower rack wheels

Cube-mould technology leads to 40% cycle time savings

The new reverse cube system from FOBOHA for ARBURG's ALLROUNDER CUBE increases quality, accelerates cycle times by up to 40% compared to two separate injection moulding machines plus assembly process, and offers enormous savings in terms of costs and installation area.

An ALLROUNDER CUBE 2900 manufactures 24 sockets out of PP and 24 wheels out of POM at the same time using a 24+24-cavity cube mould, whose halves are arranged one on top of the other. The cycle time is around 9.5 seconds. The cube mould halves rotate 90° in opposite directions. While injection takes place on one side of the cube, the components on the other three sides cool down enough so that they can be assembled directly in the mould. A six-axis robotic system takes charge of assembling the individual parts into lower rack wheels for dishwashers.

Highlights

  • Functional integration: in-mould lamination of preformed 3D films with integrated electronic module and LEDs
  • Smart component surfaces: touch functions for digitalisation in vehicle interiors in demand
  • Automated clean room cell: controlled production conditions for a reliable process
  • Quality in high volumes: 100% inspection of electrical functions

Technology

Machine
The lower rack wheels are produced on an ALLROUNDER CUBE 2900 cube-mould machine with a clamping force of 2900 kN. The servo-electric toggle-type clamping unit and the integrated 24+24-cavity mould with servo-electric cube rotation enable fast cycles combined with reduced energy consumption.

Robotic system
A multi-axis robotic system takes charge of handling individual components and finished parts using a two-part gripper. Its mobility provides a basis for reducing the complexity and costs of grippers and peripheral equipment.

Process and know-how

Multi-component injection moulding
The two independently moveable injection units are horizontally positioned and travel above the moveable mould mounting platen. The pre-moulded parts are transferred precisely and rapidly via servo-electric cube rotation. The production sequence can be reliably optimised with the central machine controller.

Industry

Technical injection moulding
In technical injection moulding, extremely precise components can be manufactured out of various plastics for all kinds of applications. For example, insulating rails made of thermoset are used in irons. In order to manufacture products like this quickly, reliably and in a cost-effective way, we can offer you special machine technology and extensive expertise.
