Preparation of coolants and lubricants

Müller Hydraulik Combiloop CL6G

Machining processes cannot do without the permanent supply of coolants and lubricants. Due to the high process speeds and precision requirements, these circulated substances must be free of particles or other impurities. Purity is ensured by special treatment systems that remove the coolant emulsions from the processing machine, filter them, sterilize them, store them temporarily and feed them back into the production process via high-pressure pumps.

Müller Hydraulik GmbH is a specialist for such treatment systems and presents the Combiloop CL6 G, a completely redesigned unit that is more powerful and at the same time cleans much better. The industrial design by defortec visualizes this special status of the unit and also took care of the functional optimization.


Design that shapes the brand

Basically, the design of peripheral devices - including the Combiloop CL6 G - can follow two different approaches. On the one hand, there is a restrained, even neutral design language that leaves the visual dominance to the main machines. The other design strategy is based on an independent design that confidently communicates the values of the machine and the manufacturer. And Müller Hydrauliks has chosen this path - the Combiloop CL6 G is the first machine in a comprehensive design revamp.


Independent and dynamic

To show this independence, defortec developed a geometry concept that does not only consist of horizontals or verticals, but places angled lines prominently. This creates a dynamic, complex and concise appearance that unmistakably stands for the manufacturer Müller Hydraulik. This connection is emphasized by the clever inclusion of the corporate color magenta, which forms a two-dimensional accent to the businesslike tones of white and dark gray.


Maintenance optimized concept

An important factor in the design concept was the optimized accessibility of the relevant functional components, especially the filter modules. Their positioning within the machine was structurally fixed; defortec developed a multi-part, hierarchical cladding system. The two sheet metal covers at the front - one removable, the other movable - only have to allow access in the event of genuine defects. Far more often, the internal particulate filters need to be accessed - which is why they are located behind a dark glass front that can easily be slid to the side. Everything that the filters separate - and that means particles over 25 μm in diameter - ends up in the chip box, which is not provided externally, as is often the case, but is completely integrated into the machine. To empty it, it is simply moved out to the side. All other cladding elements, those of the side switch box, those of the purposefully tidy rear side, and also the ceiling parts can be removed completely and, above all, quickly.

Interface behind glass

The central display and operating interface is located behind a glass front printed on the back. The large, capacitive display is thus effectively protected against dirt and damage in the rough and tumble of everyday production. Directly above this glass panel is the obligatory signal light. On the one hand, it is integrated by inclination and proportion, and on the other, it is the only element that protrudes from the silhouette of the system - in keeping with its task of indicating the current status of the machine in a way that is visible from far away.

"Color Material Finish (CMF)"

Das Color Material Finish bezeichnet grundlegende Prinzipien von Material-, Farb- und der Oberflächenqualität. Durch die CMF wird unserer Wahrnehmung und Empfindung beeinflusst. Das Color Material Finish ist für die Haptik und Optik verantwortlich, es beeinflusst die Wahrnehmung des Produktes, sowie den gefühlten Wert bei den Konsumenten. Die Verarbeitung mit gewissen Materialien, wie zum Beispiel Soft Touch, oder High Tech Nano Material können den Wert des Produktes sehr beeinflussen und einen weiteren Kaufaspekt bringen. In der Produktentwicklung nennt man diese Eigenschaften eben die CMF – Color Material Finish. Durch die individuelle Oberflächenstruktur bekommt das jeweilige Produkt seinen „Wert“, es könnte sich wertig anfühlen, oder es macht den Anschein billig zu sein. Bedeutend dafür sind die eben die Oberfläche (Optik und Haptik). Die funktionalen Punkte des Produktes, wie auch die Ergonomik, oder eine unkomplizierte Reinigung spielen ebenfalls mit rein.

Das Color Material Finish wird in sämtliche Entwicklungen des Produktes integriert, damit die Anforderungen mit der Verwendung im Einklang sind. Diese CMF-Punkte müssen vor der Serienfertigung übermittelt werden, damit das Design und das Produkt perfekt produziert werden können.
