Indlela yokucoca i-graphite mold?

Ngokubanzi, xa inkqubo yokubumba igqityiwe, ukungcola okanye iintsalela (ezineekhemikhali ezithile kunye neempawu zomzimba) zihlala zishiywaumngundo wegrafayithi. Kwiintlobo ezahlukeneyo zeentsalela, iimfuno zokucoca nazo zahlukile. Iiresins ezifana ne-polyvinyl chloride zivelisa igesi ye-hydrogen chloride, ethi emva koko idle iintlobo ezininzi zentsimbi ye-graphite die. Ezinye iintsalela zahlulwe kwi-flame retardants kunye ne-antioxidants kwaye zinokubangela ukubola kwintsimbi. Ezinye izinto ezinombala we-pigment ziya kuyigqwala intsimbi, kwaye ukugqwala kunzima ukukususa. Kwanamanzi avaliweyo ngokubanzi, ukuba abekwe phezu komphezulu we-graphite mold enganyangwanga ixesha elide, aya kubangela nomonakalo kwi-umngundo wegrafayithi.
Ngoko ke, i-graphite mold kufuneka icocwe ngokomjikelo wemveliso omiselweyo. Emva kokuba i-graphite mold ikhutshwe kwi-press rhoqo, qala uvule umngxuma womoya we-graphite mold ukuze ususe lonke ukungcola kunye ne-oxidation kwiindawo ezingezizo ezibalulekileyo ze-graphite mold kunye ne-template, ukuze uthintele ukuba ingangcolisi kancinci umphezulu wentsimbi kunye nomphetho. Kwiimeko ezininzi, nokuba emva kokucoca, ezinye ii-graphite molds ezingagqunywanga okanye ezirhabaxa ziya kuphinda zibonise i-rust kwakhona. Ke ngoko, nokuba kuthatha ixesha elide ukuhlamba i-graphite mold engakhuselekanga, i-rust ebonakalayo ayinakuthintelwa ngokupheleleyo.
Ngokubanzi, xa iiplastiki eziqinileyo, iiglasi, amaqokobhe e-walnut kunye namasuntswana e-aluminium zisetyenziswa njengezinto zokurhawuzelelauxinzelelo oluphezuluUkutyumza nokucocwa komphezulu we-graphite mold, ukuba ezi zinto zokukrala zisetyenziswa rhoqo okanye ngendlela engafanelekanga, le ndlela yokusila iya kwenza iimbobo kumphezulu we-graphite mold kwaye kube lula ukuba iintsalela zinamathele kuyo, nto leyo ebangela ukuba iintsalela ezininzi ziguge, Oku kunokukhokelela ekuqhekekeni kwangaphambi kwexesha okanye ekuqhekekeni kwe-graphite mold, nto leyo engathandekiyo ekucoceni i-graphite mold.
Ngoku, uninzi lwee-mold ze-graphite zinemigca yokukhupha umoya "eyazicocayo", ene-gloss ephezulu. Emva kokucoca nokupolisha umngxuma wokukhupha umoya ukuze ufikelele kwinqanaba lokupolisha le-spi#a3, okanye ukugaya okanye ukugaya, khupha intsalela kwindawo yenkunkuma yombhobho wokukhupha umoya ukuze uthintele intsalela ukuba inamathele kumphezulu wesiseko se-roughing mill. Nangona kunjalo, ukuba umqhubi ukhetha i-gasket yokufunxa erhabaxa, ilaphu le-emery, iphepha lesanti, ilitye lokusila okanye ibrashi ene-nylon bristle, ithusi okanye intsimbi ukuze kugaywe i-graphite mold ngesandla, kuya kubangela "ukucocwa" okugqithisileyo kwe-graphite mold.
Ngoko ke, ngokukhangela izixhobo zokucoca ezifanelekileyo kwi-graphite mold kunye netekhnoloji yokucubungula kunye nokubhekisa kwiindlela zokucoca kunye nemijikelo yokucoca ebhalwe kumaxwebhu agciniweyo, ngaphezulu kwe-50% yexesha lokulungisa linokulondolozwa kwaye ukuguguleka kwe-graphite mold kunokunciphisa ngempumelelo.
