Uma i-wax isetshenziselwa ukwenza iphethini, ukubunjwa kwe-investimenti kubuye kubizwe ngokuthi "i-wax casting elahlekile".Ukukhishwa kwe-investment ngokuvamile kubhekisela ohlelweni lokubunjwa lapho ijamo lenziwa khona ngezinto ezi-fusible, ubuso bomumo bumbozwe ngezendlalelo eziningana zezinto eziphikisayo ukwenza igobolondo lesikhunta, bese isikhunta sincibilika ngaphandle kwegobolondo lesikhunta, njengokuthola isikhunta ngaphandle kokuhlukanisa indawo, engagcwaliswa ngesihlabathi futhi ithululwe ngemva kokugazinga okuphezulu kokushisa.Ukutshala imali kuvame ukubizwa ngokuthi "i-wax casting elahlekile" ngenxa yokusetshenziswa kakhulu kwezinto ze-waxy ukwenza iphethini.

Izinhlobo ze-alloy ezikhiqizwa ukutshala izimali ziyi-carbon steel, i-alloy steel, i-alloy ukumelana nokushisa, insimbi engagqwali, i-precision alloy, i-alloy magnetic unomphela, i-bearing alloy, i-alloy yethusi, i-aluminium alloy, i-titanium alloy ne-nodular cast iron, njll.

Ngokuvamile, ukwakheka kokutshala izimali kuyinkimbinkimbi.Ububanzi obuncane bembobo yokuphonsa bungafinyelela ku-0.5mm, futhi ubukhulu bodonga obuncane bokubunjwa bungu-0.3mm.Ekukhiqizeni, ezinye izingxenye ekuqaleni ezakhiwe izingxenye eziningana zingaklanywa zibe ingxenye yonke futhi ziphonswe ngokuqondile ngokufaka utshalomali ngokushintsha ukwakheka kwezingxenye, ukuze kongiwe amahora okucubungula nokusetshenziswa kwezinto zensimbi, ukuze ukwakheka kwezingxenye kunengqondo kakhudlwana.

Isisindo esiningi se-investimenti yokutshala izimali sisuka ku-zero siye kunqwaba yama-newtons (kusuka kumagremu ambalwa kuya kumakhilogremu ayishumi nambili, ngokuvamile angabi ngaphezu kwamakhilogremu angu-25).Kunzima ukusebenzisa i-investment casting ukukhiqiza ukulingisa okusindayo.

Inqubo yokutshala izimali iyinkimbinkimbi, futhi akulula ukuyilawula, futhi izinto ezisetshenziswayo nezisetshenziswayo zibiza kakhulu.Ngakho-ke, ilungele ukukhiqizwa kwezingxenye ezincane ezinobunjwa obuyinkimbinkimbi, izidingo zokunemba okuphezulu, noma obunye ubunzima bokucubungula, njengama-blade enjini yomoya.
