Xa kuthethwa ngokungunda, abantu bahlala benxulumanisa ukungunda okuphosa ukufa kunyeisitofu sokungunda, kodwa eneneni umahluko phakathi kwazo usaphawuleka kakhulu. Njengoko i-die casting yinkqubo yokuzalisa umgodi wokubumba ngolwelo okanye i-semi-liquid metal kwizinga eliphezulu kakhulu kunye nokuqiniswa phantsi koxinzelelo lokufumana i-die casting. Ngokuqhelekileyo isetyenziswa kwisinyithi, ngelixa isitofu sokubumba kukubumba, eyona ndlela iphambili yokubumba i-thermoplastic, i-thermoplastic yenziwe nge-thermoplastic resin, enokuthi ishushu ngokuphindaphindiweyo ukuze ithambe kwaye ipholile ukuze iqiniswe, inkqubo yomzimba, ibuyiselwa umva, oku kuthetha ukuba inokuba isetyenziswe njengeplastiki esetyenzisiweyo.
Umahluko phakathi kokubumba okufayo kunye nokubumba kweplastiki.
1. Uxinzelelo lwenaliti ye-die-casting molds luphezulu, ngoko ke iimfuno zetemplate zinzima kakhulu ukukhusela ukuguqulwa.
I-2.Isango le-die-casting molds lihluke kwi-injection molds, efuna uxinzelelo oluphezulu lokwenza i-cone ye-diversion ukudiliza ukuhamba kwezinto.
I-3.I-Die-casting molds ayifuni ukucima i-kernel ye-die, kuba iqondo lokushisa ngaphakathi kwi-mold cavity lingaphezulu kwama-700 degrees xa i-die-casting, ngoko ke ukubumba ngakunye kufana nokucima kanye, i-mold cavity iya kuba nzima kwaye ibe nzima, ngelixa iimolds zesitofu jikelele kufuneka zicinywe ukuya kwi-HRC52 okanye ngaphezulu.
4.I-Die-casting molds ngokubanzi kwi-cavity kunyango lwe-nitriding, ukuthintela umngxuma we-alloy sticky.
5. Ngokubanzi ii-die-casting molds zidla kakhulu, umphezulu wangaphandle ngokuqhelekileyo unyango oluluhlaza.
I-6.Xa kuthelekiswa ne-injection molds, i-die-casting molds ine- clearance enkulu kwiindawo ezihambayo (ezifana ne-slider core), kuba ukushisa okuphezulu kwenkqubo yokufa kuya kubangela ukwanda kwe-thermal. Ukuba ukucocwa kuncinci kakhulu kuya kubangela ukuba ukungunda kubambe.
7. Umphezulu wokwahlula i-die-casting mold oneemfuno eziphezulu, kuba i-alloy liquidity ingcono kakhulu kuneplastiki, ubushushu obuphezulu kunye nokuhamba kwezinto ezinoxinzelelo oluphezulu ukusuka kumphezulu wokwahlula kuya kubhabha ngaphandle kuyingozi kakhulu.
8. I-injection molds ngokubanzi ixhomekeke kwizikhonkwane ze-ejector, iindawo zokwahlula, njl.
9. Ukubumba okungahambelaniyo, isantya senaliti yokufa, icandelo loxinzelelo lwenaliti. Iimbumba zeplastiki zihlala zijojowe kumacandelo amaninzi, zibambe uxinzelelo.
10. Umngundo Die-casting for umngundo ipleyiti ezimbini kanye ukungunda evulekileyo, iplastiki ngundo ezahlukeneyo isakhiwo imveliso ayifani.
Ukongezelela, iimbumba zeplastiki kunye ne-die-casting molds kwimveliso yentsimbi yahlukile; iimbumba zeplastiki zisetyenziswa ngokubanzi S136 718 NAK80, T8, T10 kunye nezinye intsimbi, lo gama umngundo die-casting zisetyenziswa ikakhulu 3Cr2, SKD61, H13 ezifana intsimbi ukumelana nobushushu.
