SCHEUGENPFLUG AG METERING AND DISPENSING TECHNOLOGY Atmospheric-Pressure Production and Dispensing Proven systems for Atmospheric-Pressure Dispensing and Processing The determining factors for quality dispensing are the used dispensing medium and the dispensing process itself. But dispensing is not the only demanding task. Bonding, sealing, conformal coating and the application of thermoconductive media all must be carried out economically, at top quality and with ultimate process reliability as well. For most of these tasks, atmospheric pressure dispensing is preferred over the more complex vacuum dispensing method. A range of highly efficient systems – from the manual work station to fully automated lines – are available for this purpose. When gluing, sealing, applying thermo conducting dispensing media, or sealing and conformal coating – simple dispensing tasks can be carried out under atmospheric pressure. An example would be isolation, increasing the mechanical endurance, protection against external influences, bonding, sealing or dissipation of heat from electronic assemblies. Most components – for example in aircraft or wind turbines – are required to have a long service life and very high reliability, since replacement of parts can be complicated and/or costly. (The page references refer to the general catalogue.) A dispensing process which is perfectly tailored to the task at hand positively influences the service life of the produced parts. Irregularities in the process or inhomogeneous dispensing material, however, cause parts to fail prematurely. Even if these shortcomings are already identified during the quality control phase at the end of the production process, they can result in significant losses, because bonding and dispensing are among the final steps of the production process. Poorly bonded components, however, can usually not be used as intended. As a result, not only the metering and mixing process, material preparation and feeding are essential, but also the actual process of applying the resin to the substrate. The core criteria here are quality of dispensing and application as well as process reliability. An ideal solution is available for all requirements and every budget. And if atmospheric-pressure dispensing reaches its limits for a specific task, vacuum dispensing presents an effective alternative see page 71.

Manual Work Stations – the easy, economic and reliable Entry-Level Solution that offers more The Dos manual work stations consist of modules of various performance scopes, which can be easily adapted to the process requirements and can be flexibly extended. Combining material preparation units and feeding systems with metering and dispensing systems is possible without limitations. The result is always an integrated high-performance dispensing work station. A perfectly tuned system is more efficient than stand-alone solutions, because in this case material preparation, mixing, metering and...

Systems which include a dispenser and material preparation/feeding units are generally highly flexible. They are not only available as manual work stations with a table stand. They can be easily modified into an automated stand-alone system. Integration in existing production systems or assembly lines is also easy. Standardised, documented interfaces...

Compact and optimised for simple Gluing and Dispensing Tasks The DesktopCell is a compact, integrated solution for small to medium-sized batches and for prototype production. It unites all the advantages of a fully fledged dispensing cell and a small footprint. The functionalities of the SCP 200+ control unit see page 81 are extensive, allowing to intuitively control the cell via touch screen. All information about the different metering and dispensing programs is directly programmed on the unit and stored there as well. The control unit communicates with the material feeding unit and...
