Industry 4.0 in practice: the example of elastic tension straps illustrates how part variants can be cost-effectively produced in high volumes. Due to the clever product and mold design, a flexible turnkey solution as well as direct process control, the products are produced individually on a shot-to-shot basis.
Length, color and the ends of the tension strap (hook or eyelet) can be freely selected and configured on a terminal according to customer requirements. The order is then transferred directly to the central SELOGICA control system via the OPC UA communication protocol. A compact turnkey system based around a vertical ALLROUNDER 375 V injection molding machine then produces the part variant on demand – without any need for conversion. In industrial practice, such an application is ideal for cable assembly in the automotive industry, for example.
- Individual production on demand: variant changes from shot-to-shot without any conversion
- Digital transformation: customer requirements are integrated into the running injection molding process online
- Clever product and mold design: combination mold for all fastening variants
- Flexible six-axis robotic system: automatic cutting to the required strap length
- Compact turnkey system: automation integrated in the machine installation area
Part weight: 13.5 / 14 g
Material: PP GF 30
Cycle time: 35 s
The tension straps are encapsulated on a vertical ALLROUNDER 375 V. The four-cavity mold has two cavities each for the hooks and eyelets. This allows hook/hook, hook/eyelet or eyelet/eyelet combinations to be produced. The cavities required in each case are filled via hot-runner nozzles.
to the vertical machines
Multi-axis robots offer highly flexible perfection in motion and feature high functionality on a small footprint. With the vertical ALLROUNDER V, the use of a robot makes it possible to enter the mold from the rear. For this purpose, the ends of the strap are placed into the cavities in accordance with the order.

Encapsulation of inserts
The tension straps are cut from the roll to the length required by the customer and the ends are spliced by means of a plasma process. The flexible inserts are handled by a six-axis robot that is compactly housed within the machine's installation area.
