Abstract

In the assembly processes of mechanical parts from semifinished parts and finished parts there are different levels of roughness and different types of defects. This is mainly affecting the final surface of the finished parts. The founded defects can be from different categories like: irregular shape and surface, deformed edge, processing defects, little particles that combined with high pressures can make the parts crack. In the end this affects the sealing and the tightness of the assembled goods. After assembly it can also influence the performance of the resistance, the cycle life of the parts, the dullness and also the precision of final power packs. In this paper it is going to be established what are the parameters and the conditions for a stable sealing process that could survive to different environmental pressures. This results are presented after observation of various mechanical assemblies and their guidelines in which were determined the circumstance for a proper sealing. The main functions of the adhesion are the fixation and the sealing with a mechanical connection. In order to perform on maximum capacity this connection must be stable and strong and capable to hold to every impediment and test submitted. The following application used for gluing and sealing of electronic and mechanical components can be put it on single parts or in assembled parts and also for complex circuits, having a various applicability and utility in automotive industry.
