Manufacturing process optimization of sensor for the automotive industry

Diplomsko delo obravnava specifične probleme pri izdelavi senzorjev. Ker je kupec sprožil reklamacijo, in sicer s tezo, da naj bi prenehanje vrtenja ležaja v končnem sestavu povzročilo izhlapevanje aktivatorja kot komponente pri tehnologiji lepljenja, smo bili prisiljeni spremeniti interni proces. Na podlagi zahtev internega procesa in predhodnih testiranj smo izbrali peskanje kot dodatno tehnologijo. Novo izbrano tehnologijo je bilo potrebno najprej implementirati ter ob sprostitvi delovnega mesta tudi validirati. Z uvedbo optimizacije peskanja smo pridobili tako na ponovljivosti in stabilnosti kot tudi racionalizaciji. Po neuspeli optimizaciji tehnologije lepljenja, ki je zaradi nestabilnosti botrovala nedopustno velikemu odstotku izmeta in je povezana s predhodno tehnologijo peskanja, smo slednjo nadgradili z inovativno rešitvijo, in sicer z bakrom v prašni obliki kot dodatek k peskalnem mediju.Diploma thesis deals with specific problems in sensors`. Since the buyer has field a complaint, namely that the cessation of rotation of the bearing assembly in the final product resulted in evaporation of Activator as a component of bonding technology, we were forced to change the internal process. Based on the requirments of internal process and pre-tests, we selected an additional blasting technology. New technology that has been selected should firstly be implemented and, after that validated. With the introduction of blasting optimization, we obtained the repeatability and stability of the process, as well as streamlining. After unsuccessful bonding optimization technology, which is inadmissible because of the instability and which brought about a large percentage of scrap which is associated with pre-blasting, we have upgraded the latter with an innovative solution, with copper in powder form as a supplement to the blasting medium
