Football boot sole

Modern football boots are made almost entirely from plastic. Their high-end functional components influence e.g. the speed and shooting technique of the footballer. With this product, short product life cycles require future-proof know-how and a high level of flexibility in production.

For the development of new prototypes, ARBURG designed and implemented a special vertical three-component ALLROUNDER T rotary table machine. Together with its own moulds, framas uses this mainly to produced thin-walled moulded parts such as soles and stud systems for the football boots of all the established manufacturers.

Highlights

  • Thin-walled multi-component parts: Three size 400, 400 and 290 injection units configured for low shot weights and high pressures
  • Precise injection: ARBURG’s position-regulated screw operates with a repeat accuracy equalling that of electric machines
  • Good accessibility: Rotary table with 1,500 mm table diameter, moveable in both directions
  • Suitable for small moulds: Raised injection units with extended nozzles

Technology

Machine
The vertical ALLROUNDER T with a clamping force of 2,500 kN features a servo-electric three-station rotary table. All sequences and the three injection units are managed via the central SELOGICA machine control system. The machine is configured for small moulds and thin-walled parts.
to the vertical machines

Process

Multi-component injection moulding
The two large injection units are arranged in parallel on the rear of the machine and inject the material into the parting line. The smaller unit is arranged vertically. For extremely precise injection and holding pressure performance, all the injection units feature position-regulated screws.

Industry

Technical injection moulding
In technical injection moulding, high-precision components can be produced for a wide variety of applications. High-performance functional components for football boots are in a league of their own. Special injection moulding solutions are also used for the development of high-end products such as these.
