Izisombululo

Ukubumba iplatinum kwenziwa kusetyenziswa inkqubo enamanyathelo amaninzi equka izixhobo ezikhethekileyo kunye nolwazi olubanzi malunga nendlela izinyithi ezixabisekileyo, ezifana neplatinum, ezinyibilika ngayo. Inkqubo yokubumba iplatinum ibandakanya la manyathelo alandelayo: Imodeli yewax kunye nokulungiselela ukubumba.

Ukuphosa ubucwebe bePlatinum

Iivenkile zezacholo kunye nabanye abayili bezacholo bafuna ukukwazi ukuguqula ngokukhawuleza uyilo lwabo lube zizinto ezibonakalayo ezinokuthengiswa. Iinkampani zokusika iplatinum, ezifana neCasting House, zinganceda la mashishini kunye nabayili ukuba benze iziqwenga ngazinye okanye iimveliso ezinkulu ngokubonelela ngokufikelela kwiinkonzo zokusika eziphambili.

Ukuqonda Inkqubo yokuCandwa kwePlatinum

Ukubumba iplatinum kwenziwa kusetyenziswa inkqubo enamanyathelo amaninzi equka izixhobo ezikhethekileyo kunye nolwazi olubanzi malunga nendlela izinyithi ezixabisekileyo, ezifana neplatinum, ezinyibilika ngayo.

Inkqubo yokubumba iplatinum ibandakanya la manyathelo alandelayo:

Inkqubo yokwenza ubucwebe beplatinum ifana neyokwenza ubucwebe begolide nesilivere. Umahluko omkhulu kuphela kukuba ubushushu bokunyibilika kweplatinum buphezulu kakhulu obufunekayo, obumalunga ne-1800 degrees celsius, oku kufuneka kwenziwe yiHasung Tilting Vacuum Pressure Casting Machine.

Imodeli yewax kunye nokulungiswa kokubumba. Iqhekeza lezinto zokuhombisa zeplatinum liqala ngokudala imodeli yewax yokuba isiqwenga esigqityiweyo siza kujongeka njani. Le modeli incamathiselwe kwisiqu sewax nge-sprue eya kwenza umjelo apho iplatinum enyibilikisiweyo igcwalisa khona kwimold. Ngamanye amaxesha iimodeli ezininzi zewax ziya kuncamathiselwa kwisiqu esinye ukuze kwenziwe izinto ezininzi zokubumba.
Utyalo-mali. Nje ukuba imodeli yewax ibekwe kwisiqu, ifakwa kwiflaski kwaye kugalelwe izinto zotyalo-mali ezijikeleze yona. Emva kokuba izixhobo zotyalo-mali zisetiwe, iba yimold apho iplatinum engamanzi iza kugalelwa khona. Ukusetyenziswa kwezinto zotyalo-mali ezifanelekileyo ekubunjweni kweplatinum kubaluleke kakhulu ngenxa yobushushu obuphezulu apho iplatinum inyibilika khona. Nangona kunjalo, ngaphambi kokuba iplatinum igalelwe kwimold, imodeli yewax yokuqala kufuneka itshiswe kwi-oven ekhethekileyo. Xa yonke iwax inyibilikisiwe kwaye itshisiwe, ishiya umngxuma kwizinto zotyalo-mali ezisebenza njengemold.
Ukunyibilika. Kukho ii-alloy ezininzi eziqhelekileyo ezisetyenziswa rhoqo kwi-platinum casting. Ezona zixhaphakileyo yiPlatinum 900 Iridium, enyibilika kwi-3,250 degrees Fahrenheit; Platinum 950 Iridium, enyibilika kwi-3,236 degrees Fahrenheit; Platinum 950 Ruthenium, enyibilika kwi-3,245 degrees Fahrenheit; kunye nePlatinum 950 Cobalt, enyibilika kwi-3,182 degrees Fahrenheit. Nje ukuba i-alloy inyibilike, ingagalelwa kwi-mold okanye inyanzeliswe ukuba isetyenziswe enye yeendlela ezahlukeneyo.
Ukuphosa. Nangona isinyithi esilulwelo sinokugalelwa nje kwisikhunta, iindlela ezahlukeneyo zibonelela ngokuphosa okusemgangathweni ophezulu ngokulawula ukuhamba kwesinyithi kwisikhunta. Ukuphosa i-centrifugal kusebenzisa i-centrifuge ukujikelezisa iflaski kwaye kusebenzise amandla e-centrifugal ukusasaza isinyithi ngokulinganayo kuyo yonke isikhunta. Ukuphosa okuncediswa yi-vacuum kutsala isinyithi kwisikhunta ngokusebenzisa ukufunxa. Ukuphosa isinyithi ngokuxinzelela kubeka iflaski ngaphakathi kwigumbi elinoxinzelelo. I-Casting House isebenzisa zonke ezi ndlela zintathu kunye nokuphosa ithoshi, esebenzisa ithoshi ukunyibilikisa inani elincinci kakhulu lesinyithi eligalelwa kwisikhunta.
Ukuhlutha Oku kuquka ukususa ukuthungwa kutyalo-mali, nokuba kungeendlela zomzimba okanye zeekhemikhali. Utyalo-mali lunokubethelwa ngesando, luqhunyiswe ngejethi yamanzi okanye ludlidlizwe, okanye abavelisi bangasebenzisa isisombululo sokuyinyibilikisa. I-sprue kwisiqwenga ngasinye iyanqunyulwa kwaye isetyenziselwe ukuthungwa kwixesha elizayo, kwaye isiqwenga esigqityiweyo siyacocwa ukuze kususwe naziphi na iziphene.
Imfuneko yokudityaniswa kolwazi olukhethekileyo kunye nokufikelela kwizixhobo ezithile ithetha ukuba uninzi lweevenkile zobucwebe kunye nabayili baxhomekeke kwiinkampani zokusika iplatinum ukuze benze le nkonzo. Iingcali ezisebenza kwezi nkampani zokusika iplatinum zinamava afunekayo okwenza iziqwenga zobucwebe ezikumgangatho ophezulu. Zikwanokufikelela kwiteknoloji yokubumba esemgangathweni kunye ne-photopolymer.
