    • نبذة مختصرة :
      Ideja ovog završnog rada je prikazati izradu klasičnog kalupa s jednim gnijezdom za proizvodnju gumene brtve leptir ventila. Prilikom konstrukcije i izrade kalupa potrebno je obratiti pozornost na pravilan odabir materijala, funkcionalnost, linije dijeljenja, vođenje, skupljanje gumenog proizvoda nakon hlađenja (proizvodnja se odvija na temperaturama iznad 120°C ovisno o vrsti gume), potrebni broj ciklusa koje kalup mora izdržati i potrebni vijek trajanja. Prilikom izrade potrebna je detaljna analiza nacrta, oblika kalupa, dimenzija, tolerancija i ostalih zahtjeva te u skladu s tim odabrati odgovarajući način izrade. ; This final work idea is to show production of a classic mold whit single cavity for the production of a rubber seal butterfly valve. During designing and making molds, care must be taken to properly selection of material, functionality, splitting lines, guiding, collecting the rubber product after cooling (production is done at temperatures above 120 ° C depending on the type of rubber), the required number of cycles the mold has to withstand and required lifetime. During production a detailed analysis of drafts, mold shape, dimensions, tolerances and other requirements is required, and accordingly select the appropriate way of production.
