Ixesha Elifunekayo Ukwenza I-Silicone Mold

Ixesha Elifunekayo Ukwenza I-Silicone Mold
Ukubumba i-silicone yinkqubo eguquguqukayo nesebenzayo esetyenziswa kumashishini ahlukeneyo ukwenza iimveliso ezikumgangatho ophezulu ezineenkcukacha ezintsonkothileyo. Ixesha elifunekayo ukwenza i-silicone mold linokuchatshazelwa zizinto ezininzi, kubandakanya uhlobo lwe-silicone esetyenzisiweyo, ubunzima boyilo, kunye nendlela ethile yokubumba esetyenziswayo. Kule posi yebhlog, siza kuhlola iinkqubo ezahlukeneyo zokubumba i-silicone kunye nexesha ekufuneka liqwalaselwe kuyo nganye.

Ukubumba kweSilicone yoBushushu obuPhezulu (HTV)
I-High-temperature vulcanization (HTV) yinkqubo esetyenziselwa ukuvelisa iirabha ze-silicone ezinamandla aphezulu ezifanelekileyo kwizicelo zoshishino. Le nkqubo yenziwa ngomatshini wokushisa kwaye idla ngokuthatha imizuzu embalwa ukugqiba inkqubo ye-vulcanization. Ixesha elikhawulezayo lokunyanga le-HTV lenza ukuba ibe lukhetho olufanelekileyo kwimijikelo yemveliso ekhawulezayo.

Ubushushu beGumbi Ukubumba iSilicone (RTV)
Ukucoca ubushushu begumbi (i-RTV) yinkqubo ecothayo xa ithelekiswa ne-HTV, kusetyenziswa i-platinum catalyst ethatha malunga neeyure ezingama-24 ukunyanga nokwenza iimveliso zerabha ze-silicone ezithambileyo nezithambileyo. Le ndlela ifanelekile ukusetyenziswa apho kufuneka ukuguquguquka nokuthamba.

Indlela yokuGumba yokuDlulisa iSilicone
Ukubumba i-silicone transfer molding yindlela echanekileyo enika amaxesha omjikelo akhawulezayo xa kuthelekiswa nezinye iindlela zokubumba. Igqiba umjikelo malunga nemizuzwana engama-30-45, okukhawuleza kakhulu kunobumba boxinzelelo, okuthatha malunga nemizuzu emi-2-3 ngomjikelo ngamnye. Ukusebenza kakuhle kokubumba i-silicone transfer molding kuvela kuyilo lwayo olulodwa lokucinezela kunye noyilo lwangaphambi kokwakheka, olunciphisa kakhulu amaxesha omjikelo.

Ukuthelekiswa nezinye iindlela zokubumba
Ukubumba ngenaliti: Ukubumba kwe-silicone transfer kusebenza kwiingcinezelo eziphantsi (1,500-2,500 PSI) xa kuthelekiswa nokubumba ngenaliti (10,000-30,000 PSI), nto leyo ebangela ukuba izixhobo zingagugi kakhulu kwaye zikrazuke kwaye zingcono kwizixhobo ezibuthathaka kwiingcinezelo eziphezulu.

Ukubumba Ngesivuthuvuthu: Ukubumba kwe-silicone kwahlukile ekubumbeni ngokubhoboza ngokusebenzisa inkqubo yegumbi ukuhambisa i-silicone eshushu kwangaphambili kwindawo yokubumba, okwenza ukuba ilungele iindawo ezineenkcukacha nezichanekileyo.

Ukubumba okujikelezayo: Ngelixa ukubumba okujikelezayo kujikeleza ukubumba ukuze kusasazwe izinto ngokulinganayo, ukubumba okutshintshiselwayo kwe-silicone kusebenzisa uxinzelelo ukutyhala izinto ezifudunyezwe kwangaphambili kwi-mold, kufezekisa ukuchaneka okuphezulu kunye namaxesha okujikeleza akhawulezayo.

Ukulungisa i-thermoforming: Ukubumba kwe-silicone kulungele iindawo ze-3D ezineenkcukacha ezintsonkothileyo, ngokungafaniyo ne-thermoforming, efudumeza iphepha leplastiki ize ilibumbe phezu kwesikhunta.

Ukubumba i-Extrusion: Ukubumba kwe-silicone kudala iindawo ze-3D, ngelixa ukubumba kwe-extrusion kwenza iimilo ezinde neziqhubekayo ze-2D

Ukubumba okuncinci: Ukubumba okudluliswa kwesilicone kuphatha iindawo ezinkulu kwaye kukhawuleza, okwenza kube yeyona nto ifanelekileyo kwimveliso ephezulu, ngokungafaniyo nokubumba okuncinci, okugxile kwiindawo ezincinci.

Ukubumba Inaliti Yempendulo (RIM): Ngokungafaniyo ne-RIM, exhomekeke kwiimpendulo zeekhemikhali ukuze zenze iindawo, i-silicone transfer molding ifudumeza i-silicone emile okwexeshana ize iyityhalele kwi-mold, nto leyo ekhokelela kutshintsho kumandla, iinkcukacha, kunye nesantya sokuvelisa.

Isiphelo
Ixesha elifunekayo ukwenza i-silicone mold lixhomekeke kwinkqubo ethile kunye nokusetyenziswa kwayo. I-silicone transfer molding, ngokukodwa, inika indlela ekhawulezayo nefanelekileyo yokwenza iindawo ze-silicone ezichanekileyo. Ukuqonda umahluko phakathi kweendlela zokubumba ze-silicone kunye neemfuno zazo zexesha kunokunceda abavelisi ukuba baphucule iinkqubo zabo zemveliso ukuze zisebenze kakuhle kwaye zibe semgangathweni.
