For over 30 years, Walter Exeron GmbH has been one of the most important German manufacturers of mold cavity plants for tool and mold manufacture. In the Fluorn-Winzeln manufacturing plant, about 90 km south-west of Stuttgart, 75 employees make EDEM systems for reputable customers such as Bosch, BMW and Mercedes-Benz.
Such complex, state-of-the-art machines can only be produced cost-effectively by using ingenious and easy to install automation technology. Walter Exeron has solved this problem by consistently using PHOENIX CONTACT Interface products.
All the mold cavity plants made by Walter Exeron work on the principle of spark erosion. Here, the material carrying effect of electrical discharge between two conducting electrodes. The workpiece forms the first electrode, the tool forms the second.
EDEM technology is often used
for making
injection-mould
tools
Tool and workpiece are advanced towards each other in an insulated, dielectric fluid until the pulsating direct voltage applied initiates a discharge. This discharge causes a layer of molten metal to form on the workpiece, which is rinsed away by the dielectric fluid. Repeated discharges cause the outersurface of the workpiece to be continuously eroded.
The accurately controlled movement of the electrode allows a very precise volume of any shape to be formed from any workpiece which can conduct electricity.
To control the signal sequences, a multitude of measurement, control and regulation values are necessary. For this purpose, the electrical values are transmitted to the central control via the INTERBUS-IP65 local bus, where they are evaluated and then sent on to the appropriate actuator.
QUINT POWER withstands the harshest
environments
A centrally-installed three-phase QUINT POWER 20 A power supply takes over all the
active consumers. This module is particularly suitable for the rough daily use in
industry. Even continuous overloading does not cause the equipment to switch off, but
makes the full 22 A supply available with reduced output voltage. In this way, sufficient
reserves are available to supply INTERBUS, the most varied relays and the complete
24 V periphery.
The efficiency of over 90% limits the
heat loss. This prevents the switch cabinet from heating up. The wide input voltage range
of 320-350 and the full capacity of QUINT POWER, even if one phase fails, guarantee a
steady supply to this innovative technology, even during serious mains interruptions.
