Umbhobho wokubumba ubhedu, kwaziwa njengeTp2 umbhobho wokubumba or Umbhobho wokungunda weCuag, idlala indima ebalulekileyo kwizicelo ezahlukeneyo zemizi-mveliso.Le mibhobho yenzelwe ngokukodwa ukumelana nokushisa okuphezulu kunye noxinzelelo, okwenza kube yinto ebalulekileyo kwimveliso yeemveliso ezahlukeneyo.Ukususela ekuveliseni iimveliso zeplastiki ukuya kwimveliso ye-alloys yesinyithi, iityhubhu ze-Tp2 zobhedu zisetyenziswa kakhulu kumashishini ahlukeneyo.

Enye yeenzuzo eziphambili ze-Tp2 ityhubhu yokubumba i-copper yi-conductivity yayo egqwesileyo ye-thermal.Olu phawu luvumela ukuhanjiswa kobushushu ngexesha lokwenziwa kwemveliso, ukuqinisekisa ukuchaneka kunye nokungaguquguquki ekubunjweni kwemveliso.Nokuba ubumba isinyithi esityhidiweyo kwisingundo esithile, okanye imathiriyeli yeplastiki yokupholisa ukufikelela kwimilo efunekayo, i-thermal conductivity ye-Tp2 ityhubhu yokungunda yobhedu iyafuneka.

Ukongeza, umbhobho wokungunda wobhedu we-Tp2 unokumelana ne-corrosion eyomeleleyo, okwenza ukuba ilungele ukusetyenziswa ixesha elide kwiindawo zoshishino ezinzima.Oku kuxhathisa i-corrosion kuqinisekisa ixesha elide lombhobho wokubumba, ukunciphisa imfuno yokutshintshwa rhoqo kunye nokugcinwa.Abavelisi ke ngoko banokuthembela kwiityhubhu zokubumba ze-Tp2 zobhedu kwinkqubo yokuvelisa eqhubekayo, engaphazamisekiyo.

Ukongeza kwiipropati zayo zokumelana nobushushu kunye nokubola, umbhobho wokubumba ubhedu we-Tp2 uyaziwa ngokuba namandla awo aphezulu.La mandla avumela ityhubhu ukuba imelane noxinzelelo olunzulu kunye namandla omatshini abandakanyekayo kwinkqubo yokuvelisa.Ingaba i-injection yentsimbi etyhidiweyo okanye i-extrusion yezixhobo zeplastiki, iityhubhu ze-Tp2 ze-copper mold zibonelela ngenkxaso yesakhiwo esiyimfuneko ukugcina ingqibelelo yemveliso eveliswayo.

Ngokubanzi, i-Tp2 Copper Mold Tube licandelo eliyimfuneko kwizicelo zamashishini apho ukuchaneka, ukuqina kunye nokuthembeka kubalulekile.I-thermal conductivity yabo, ukuxhathisa ukubola kunye namandla okuqina kubenza babaluleke kakhulu kwimveliso esebenzayo yeemveliso ezahlukeneyo.Njengoko ishishini liqhubeka nokuvela kwaye lifuna iinkqubo zokwenziwa komgangatho ophezulu, iityhubhu ze-Tp2 zekristalliza zobhedu ziya kuqhubeka ziyinto ephambili ekuhlangabezaneni nezi mfuno.
