Ukuba uyazibuza ukuba yeyiphi eyona ndlela inoqoqosho yokwenza nayiphi na iprototype?Emva koko kufuneka uzame ukwenza ivacuum cast.Kwi-vacuum casting, kufuneka ube namaqondo obushushu achanekileyo xa unyanga imathiriyeli.
Kwi-resin, udinga i-30 degrees Celsius ukunciphisa ukucutheka ngexesha loxinzelelo lwe-vacuum yemizuzu emi-5 kunye nobushushu bokubumba obungama-60 degrees Celsius.
Ukukhutshwa kwevacuum kuyafana nokuphindaphinda usebenzisa i-silicon mold.Iplastiki yokufunxa iplastiki kusetyenziswa ukubumba isilicon yaphuhliswa ngeminyaka yoo-1960 kwiidyunivesithi zaseJamani.
Ngaba i-vacuum casting inceda njani inkampani yakho?Qhubeka ufunda eli nqaku ukuze ufumanise.
1. Yintoni iVacuum Casting?
Le yinkqubo yokuphosa kwi-elastomers esebenzisa ivacuum ukutsala nayiphi na imathiriyeli engamanzi kumngundo.I-vacuum casting isetyenziswa xa ukuvalelwa komoya kuyingxaki ngokungunda.
Ukongezelela, inkqubo ingasetyenziselwa xa kukho iinkcukacha eziyinkimbinkimbi kunye ne-undercuts kwi-mold.Kwakhona, isetyenziswe ukuba izinto ezisetyenziselwa ukwenza isikhunta yifiber okanye ucingo oluqinisiweyo.
Inkqubo ngamanye amaxesha ibizwa ngokuba yi-thermoforming kuba inkqubo yokuvelisa ibandakanya iprototyping ekhawulezayo apho amaphepha eplastiki afudunyezwa.Izinto ezisetyenziswayo zifudunyezwa kumatshini wokugalela ivacuum ozenzekelayo de zibe zithambile kwaye zithobeke.
2. Isebenza Njani iVacuum Casting?
Ukukhupha ivacuum kulandela inkqubo esetyenziswa ukwenza imveliso yokugqibela.
• Yiba neModeli yoMgangatho oPhezulu
Inkqubo yokukhupha ivacuum ifuna ukuba ube nemodeli ekumgangatho ophezulu.Imodeli esemgangathweni ophezulu ingaba yinxalenye yoshishino ngokwayo.Ukongeza, ungasebenzisa imodeli eyenziwe usebenzisa i-stereolithography, eyimeko yezicelo zeprototyping.
Kufuneka uhlale uqinisekisa ukuba imodeli eyintloko esetyenziswayo yeyemilinganiselo echanekileyo kunye nenkangeleko.Oku kukuqinisekisa ukuba akukho ziphoso zikhutshelwa kwiprototype yemodeli emva kokugqiba inkqubo.
• Inkqubo yoNyango
Imodeli eyinkosi ke ifakwe kwi-mold ye-silicone yerabha enamacala amabini.Umngundo unyangwa phantsi kobushushu obuphezulu ukuqinisekisa ukuba la malungu mabini anamathelana.Oku kusetyenziselwa ukuqinisa ukubumba kunye nokwenza ukuba kube yinto ehlala ixesha elide.
Emva kokuba umngundo unyangekile, uyasikwa uvuleke ukuze kuvele indawo enomgongxo embindini, enemilinganiselo echanekileyo yemodeli ebalaseleyo.Emva kokuba ukubunjwa kunqunywe kubini, kufakwe kwigumbi lokucoca.Emva koko, kamva, i-mold izaliswe ngezinto ezichongiweyo ukwenza imveliso.
• Ukuzalisa iResin
Kufuneka ugcwalise isikhunta kunye nezinto ezikhethiweyo.I-resin iphindaphinda iimpawu zezinto zoshishino.Izinto ze-resin zihlala zixutywa kunye ne-metallic powder okanye nayiphi na i-pigment yombala ukufezekisa ubuhle okanye iimpawu ezithile zokusebenza.
Emva kokuba isikhunta sigcwaliswe ngezinto ze-resin, zifakwe kwi-vacuum room.Ifakwe kwigumbi le-vacuum ukuqinisekisa ukuba akukho amaqamza omoya kwi-mold.Oku kukuqinisekisa ukuba imveliso yokugqibela ayonakaliswa okanye yonakaliswe.
• Inkqubo yokuGqibela eNyangelwe
I-resin ifakwe kwi-oven kwinqanaba lokugqibela lokuphiliswa.Isikhunta sinyangwa kumaqondo aphezulu okushisa ukuze kuqinisekiswe ukuba izinto eziphathekayo zinamandla kwaye zihlala zihlala njalo.Umngundo we-silicone uyasuswa kwi-mold ukuze isetyenziswe ekwenzeni iiprototypes ezininzi.
Emva kokuba iprototype isusiwe kwi-mold, ipeyintiwe kwaye ihonjiswe.Umzobo kunye noyilo lusetyenziselwa ukuqinisekisa ukuba imveliso inenkangeleko entle yokugqibela.
3. IiNzuzo zeVacuum Casting
Oku kulandelayo zizinto ezilungileyo zokusebenzisa i-vacuum cast kwiimveliso eziphindaphindayo.
