New Manufacturing Process Enables Design-conforming Components

However, the company is also constantly testing and utilising new procedures and technologies, ensuring that Vauth-Sagel is always expanding its competencies and working in accordance with the very latest technological standards. For the SCF mixer front panel of an anaesthetic device, Vauth-Sagel acquired skills and know-how in the area of UV adhesion procedures.

Wellknown brands utilise special shapes and colours to increase their recognition value among end consumers. This process is meanwhile also establishing itself in other areas: medical devices, for example, are increasingly subject to stringent design requirements – with the remit that the colours of the devices, in particular, now have to comply with strict parameters of the customer’s corporate design. Vauth-Sagel’s know-how and expertise acquired over the course of decades in design-oriented furniture and automobile industries, for example, also help the company take on these challenges with ease.

Device front panel with highend design

The SCF mixer front panel is the decorative front panel of an anaesthetic device designed for metering and mixing anaesthetic gases, whereby the fascia perfectly hugs the shape of the housing. The outstanding quality of the lacquered surface and of the multi-coloured print (metallic-lacquered and eight-step printed) underline the highend appearance of the device.

Precision adhesion using photo-reactive adhesives

The special challenge was to integrate a two-window display in the front panel of the SCF mixer. To this end, the requirements in terms of surface thickness as well as the strength of the connection demanded the implementation of UV-adhesion, a process that had never been used by Vauth-Sagel up until that point. To this end, the existing robot metering system is used with a precision, triaxial CNC-controlled line and the adhesive accurately applied to the reverse side of the window cut-out. In the next work step, the window is accurately positioned with an even gap all the way around. During the entire UV-LED expo-sure period, the window is fixed to the front panel by means of a vacuum. Only once the component has hardened can it be removed from the tools and access is only permitted once an electromechanical release has been activated. While making the tools, Vauth-Sagel drew on standard components from its own fittings’ program, integrating a control unit into the manufacturing procedure.
