Izisombululo

Ukuphosa iplatinam kwenziwa kusetyenziswa inkqubo enamanyathelo amaninzi ebandakanya izixhobo ezikhethekileyo kunye nolwazi oluninzi ngendlela iintsimbi ezixabisekileyo, njengeplatinam, zinyibilika ngayo. Inkqubo yokuphosa iplatinam ibandakanya la manyathelo alandelayo: Imodeli yewax kunye nokulungiswa kokuphosa.

Platinum Jewelry Casting

Iivenkile zobucwebe kunye nabaqulunqi abathile bobucwebe bafuna ukukwazi ukuguqula ngokukhawuleza ukuyila kwabo kwizinto eziphathekayo ezinokuthengiswa. Iinkampani zokuphosa zePlatinam, njengeCasting House, zinokunceda la mashishini kunye nabayili benze iziqwenga zomntu ngamnye okanye imveliso enkulu eqhutywa ngokunikezela ukufikelela kwiinkonzo eziphambili zokuphosa.

Ukuqonda iNkqubo yePlatinam yokuCasa

Ukuphosa iplatinam kwenziwa kusetyenziswa inkqubo enamanyathelo amaninzi ebandakanya izixhobo ezikhethekileyo kunye nolwazi oluninzi ngendlela iintsimbi ezixabisekileyo, njengeplatinam, zinyibilika ngayo.

Inkqubo yokuphosa iplatinam ibandakanya la manyathelo alandelayo:

Inkqubo yokwenza izacholo zeplatinam iyafana negolide kunye nobucwebe besilivere. Umahluko ophambili kuphela liqondo lokunyibilika kweplatinam liphezulu kakhulu elifunekayo elimalunga ne-approx. I-1800 degree celsius, oku kufuneka kwenziwe ngumatshini weHasung Tilting Vacuum Pressure Casting.

Imodeli yewax kunye nokulungiswa kokuphosa. Isiqwenga sobucwebe beplatinum siqala ngokudalwa kwemodeli ye-wax yento eya kukhangeleka ngayo isiqwenga esigqityiweyo. Lo mzekelo uncanyathiselwe kwisiqu se-wax nge-sprue eya kwenza umjelo apho iplatinam etyhidiweyo igcwalisa kwi-mold. Ngamanye amaxesha iimodeli ezininzi ze-wax ziya kuncanyathiselwa kwisiqu esinye kwii-castings ezininzi.
Utyalo-mali. Emva kokuba imodeli ye-wax ibekwe kwisikhondo, ifakwe kwiflask kwaye i-investment material igalelwe ngeenxa zonke. Emva kweesethi zezinto zotyalo-mali, iba ngumbumba apho iplatinam yolwelo iya kugalelwa kuyo. Ukusetyenziswa kwezinto ezifanelekileyo zotyalo-mali kwiplatinam kubaluleke kakhulu ngenxa yobushushu obuphezulu apho iplatinam inyibilika Ukutshisa. Ngaphambi kokuba iplatinam igalelwe kumngundo, nangona kunjalo, imodeli yewax yokuqala kufuneka itshiswe kwiziko elikhethekileyo. Xa yonke i-wax inyibilika kwaye itshiswa, ishiya i-cavity kwizinto zotyalo-mali ezisebenza njenge-mold.
Ukunyibilika. Zininzi iialloyi eziqhelekileyo ezisetyenziswa kwiplatinam. Ezona zixhaphakileyo yiPlatinum 900 Iridium, enyibilika kwi-3,250 degrees Fahrenheit; iPlatinum 950 Iridium, inyibilika kwi-3,236 degrees Fahrenheit; IPlatinum 950 Ruthenium, inyibilika kwi-3,245 degrees Fahrenheit; kunye nePlatinum 950 Cobalt, enyibilika kwi-3,182 degrees Fahrenheit. Emva kokuba i-alloy inyibilikile, inokugalelwa kwi-mold okanye inyanzeliswe ekusebenziseni enye yeendlela ezininzi.
Iyaphosa. Nangona isinyithi esilulwelo sinokugalelwa nje kukungunda, iindlela ezahlukeneyo zobugcisa zibonelela ngomgangatho ophakamileyo wokujula ngokulawula ukuhamba kwesinyithi kubumba. I-Centrifugal casting isebenzisa i-centrifuge ukujikeleza iflaski kwaye isebenzise amandla aphakathi ukusasaza isinyithi ngokulinganayo kulo lonke ukungunda. Ukuphosa okuncediswa yivacuum kutsala isinyithi phezulu kumngundo ngokusetyenziswa kokufunxa. Ukuphoswa koxinzelelo kubeka iflaski ngaphakathi kwegumbi elinoxinzelelo. I-Casting House isebenzisa zontathu ezi ndlela kunye nokuphosa itotshi, esebenzisa itotshi ukunyibilikisa isixa esincinci sesinyithi esigalelwa kumngundo.
Ukuntywila Oku kubandakanya ukususa ukuphosa kutyalo-mali, nokuba kungezinto eziphathekayo okanye zekhemikhali. Utyalo-mali lunokubethelwa, luqhunyiswe ngejethi yamanzi okanye lungcangcazele, okanye abavelisi banokusebenzisa isisombululo ukuyinyibilikisa. I-sprue kwisiqwenga ngasinye siyanqunyulwa kwaye siphinde sisetyenziselwe ukuchithwa kwexesha elizayo, kwaye isiqwenga esigqityiweyo siyacocwa ukuze sisuse nakuphi na ukungafezeki.
Isidingo sokudityaniswa kolwazi olukhethekileyo kunye nokufikelela kwizixhobo ezithile kuthetha ukuba uninzi lweevenkile zobucwebe kunye nabaqulunqi baxhomekeke kwiinkampani zokuphosa iplatinam ukwenza le nkonzo. Iingcali ezisebenza kwezi nkampani zeplatinam zinamava afunekayo ukwenza iziqwenga zezacholo eziphezulu. Bayakwazi ukufikelela kwi-cut-edge molding kunye ne-photopolymer teknoloji.
