Abavelisi bokuphosa ngokuchanekileyo bachaza inkqubo ye-silica sol cast ngokweenkcukacha!

Inkqubo yotyalo-mali echanekileyo yangoku ikhula ngokukhawuleza, kwaye iyathandwa ngenxa yenkangeleko yayo entle kwaye ecocekileyo.Ngokwendlela yangoku, iimveliso zamalungu eziveliswe ngokuchaneka ngokusasazwa kwixesha elizayo ziya kuba zikhulu ngakumbi.Itekhnoloji yendabuko engenanto ngoku Ngaphantsi kophuhliso lweemarike, iyancipha ngokuthe ngcembe.Kule mihla, iimfuno zomgangatho kunye neemfuno zenkqubo yokuphosa iimveliso kwimarike ziya zinyuka ngokunyuka, amandla obugcisa afunekayo nawo aya enyuka ngokunyuka, kwaye imfuno yentsebenziswano yobuchwephesha iya kuba phezulu kuphela.

Kubenzi bokuphosa ngokuchanekileyo, inkqubo yangoku ethandwayo kufuneka ibe yeyenkqubo ye-silica sol echanekileyo yokuphosa.Ke yintoni inkqubo yale nkqubo?Inkqubo esisiseko yile ilandelayo :

1. Ngundo

Ukwenza iicastings, abavelisi bokuphosa ngokuchanekileyo kufuneka baqale benze imibundo.Ngaphambi kokuphunyezwa kweenkqubo ezithile, abavelisi baya kuyila kwaye bakhe iiprototypes ngokwemizobo ebonelelwe ngumsebenzisi, kwaye emva koko benze i-molds esekelwe kwimidwebo.

2. Umthwebeba

Nyibilikisa i-wax yokubumba ibe yimeko engamanzi, uze uyigalele kwisixhobo sokugcina ubushushu.Masime ukususa amanzi kunye nokungcola okuseleyo, emva koko wongeze i-wax entsha de umthamo wangaphakathi ufezekise iimfuno zomngundo esiwufunayo, uze ugalele i-wax kwi-mold yangaphambili, ulinde ukuba i-wax iphole kwaye iqine, kwaye uyikhuphe. .Yenza ukucheba ukuze ubone ukuba iyahambelana nomgangatho.Ukuba ayihambisani nomgangatho, iya kuphathwa njengenkunkuma, kwaye inyathelo lokunyuka liza kuqala kwakhona.

3. Ukwenza iqokobhe

Dlulisa uhlobo lwe-wax oluhlangabezana neemfuno ngodaka olungaphezulu, ukomisa, ukutywina, kunye nokoma.

4. Ukuphosa

Igobolondo elungiselelwe kwinqanaba langaphambili igalelwe kwaye inokwahlulwa ibe ngamacandelo amabini: isisombululo esiqinileyo kunye nesigqubuthelo se-buckle sokugalela.Emva kokuba ezi nxalenye zimbini zigqityiwe, iqokobhe liyapholiswa lize lisuswe, lize liphakanyiswe lize lisikwe ngaphambi kokuba libuyele ezikweni.

5. Coca kwaye ulungise

Beka izinto zentsimbi kwi-hydrofluoric acid kwaye uyicwilise, kwaye emva koko uhambe ngamanyathelo e-sandblasting, ukususwa okungundoqo kunye nokudutyulwa kokudubula, kwaye emva koko uqhube uhlolo lwesibini.Ukuba kukho imveliso yenkunkuma, inyathelo lokuthulula liphinda liphindwe.
