How to Optimize the Dispensing Process E


By Dr. Karin Steinmetzer, Marketing Manager, Scheugenpflug


ffective and reliable dis- pensing requires that process technology be set


up specifically for the applica- tion. Anyone tasked with plan- ning dispensing systems and responsible for the processes should know the principles and key factors involved so that the dispensing processes can be suc- cessfully implemented in cooper- ation with system and material partners.


Examining Process Technology


Examining process technolo-


gy from many different perspec- tives will save time and money. It will also improve product qual- ity. Examining process technolo- gy along the value chain of a product will have a considerable impact on the effectiveness of the dispensing process. As current trends progress,


the demands on process technol- ogy (materials, cycle times, etc.) may increase depending on the project. In such cases, conflicts between time, costs, quality, and flexible production can be solved with customized systems. As a rule, however, system solutions are generally sufficient. Liquid sealants, adhesives


and potting materials are used today for a wide variety of tasks and the applied material often performs several functions. Process technology is flexi- ble enough to handle any materi-


es often make it difficult to specify an exact solution. For example, many e-mobility components are being developed and, in most cases, produced with materials that must be dispensed.


pensing is always based on the same sub-processes or sub-sys- tems. A partial element that has not been properly implemented will damage the entire process and lead to higher costs, time lost and possible loss of quality.


Material Preparation Material preparation ensures


that the material has and retains the desired homogeneity, is opti- mally tempered, and is protected against moisture. Many materials are filled as standard. Fillers tend to settle. The material becomes inho-


mogeneous, which affects not only subsequent processes but also the quality of a seal or bond. The effects of temperature on the sedimentation process must also be considered. The thinner the medium, the faster the fillers settle.

becomes “project-related docu- mentation.” In these projects, it is important to engage everyone involved in the process chain at an early stage, in order to ensure the best results. Effective and reliable dis-

ants, adhesives and potting materials get into the dispenser, they may falsify the amount dis- pensed and the mix ratio and cause malfunctions in the prod- uct. If the task requires bubble-
