Abstract

V podjetju ELTI d.o.o. izdelujejo filter UHF signala, ki ima glavno funkcijo, da filtrira TV signal (odstrani neustrezen frekvenčni pas). V podjetju so se odločili, da se bo izdeloval nov model filtra (BF4-7C250D-C), ohišje filtra pa se bo za razliko od prejšnjih modelov, ki so se izdelovali s postopkom frezanja, izdelovalo s postopkom litja. Za izdelovanje ohišja so se odločali med različnimi postopki litja, na koncu pa so izbrali litje v pesek, ki je najcenejša, ampak še vedno dovolj kakovostna rešitev. Pri zasnovi je bilo treba upoštevati določena livarska pravila in tako v tehnološkem smislu prilagoditi obliko izdelka, pri čemer pa se njegova funkcionalnost ne sme v ničemer spremeniti. Tako smo, za razliko od prejšnjih modelov, kjer je bilo ohišje filtra pokrito s pokrovom, zdaj izdelali ohišje iz dveh enakih polovic, ki se med seboj spojita z vijaki. S to rešitvijo pa smo dosegli tudi željen prihranek.

Secondary title: Design and development of UHF filter
Secondary abstract: The Company ELTI d.o.o. manufactures UHF Filter, which has a main function to filter out the TV signal (remove inappropriate frequency band). The Company has decided, that it will be produced a new model of filter (BF4-7C250D-C). The Housing will be in contrast to previous designs, which have been manufactured by the proces of Miling, manufactured by the process of Casting. For making Housing, they were deciding between different procedures of Casting, at the end they chose Sand Casting, which is cheaper but still enough quality solution. The design should meet all the requirements of the casting technology while fully maintain its functionality. Unlike in previous designs where the Filter body is covered with a Lid, we have now created a Housing of two euqal halves, which are mutually fastened by means of Screws. With this solution, we have achieved the desired savings.
