Imikhiqizo ye-OEM yokukhipha i-vacuum yangokwezifiso yensimbi empunga kanye ne-spheroidal graphite (SG) ductile nodular cast iron enokwelashwa okushisayo, ukwelashwa kwendawo kanye nensizakalo yemishini ye-CNC.
I-Vacuum Casting ibizwa nangokuthi i-Negative Pressure Sealed Casting, i-Reduced Pressure Casting noma i-V Process Casting. Ukukhishwa kwengcindezi ye-vacuum kudinga ukusetshenziswa kwemishini yokukhipha umoya ukuze kukhishwe umoya ngaphakathi kwesikhunta sokuphonsa, bese usebenzisa umehluko wengcindezi phakathi kwangaphakathi nangaphandle kwesikhunta ukumboza ifilimu yepulasitiki eshisayo kuphethini nesifanekiso. Isikhunta esibunjiwe sizoba namandla ngokwanele ukumelana nensimbi encibilikisiwe ngesikhathi sokubunjwa. Ngemuva kokuthola isikhunta se-vacuum, gcwalisa ibhokisi lesihlabathi ngesihlabathi esomile ngaphandle kwe-binder, bese uvala indawo engaphezulu yesikhunta sesihlabathi ngefilimu yepulasitiki, kulandelwa i-vacuum ukwenza isihlabathi siqine futhi siqine. Ngemuva kwalokho, susa isikhunta, ubeke ama-sand cores, uvale isikhunta ukuze wenze konke kulungele ukuthululwa. Ekugcineni, ukubunjwa kutholakala ngemva kokuba insimbi encibilikisiwe ipholile futhi iqina.

I-Ductile cast iron, ebizwa nangokuthi i-nodular cast iron, i-spheroidal graphite cast iron noma nje i-SG iron ngamafuphi, imele iqembu lensimbi ekhonjiwe. I-nodular cast iron ithola i-nodular graphite ngokusebenzisa i-spheroidization kanye nokwelashwa kwe-inoculation, okuthuthukisa ngokuphumelelayo izakhiwo zemishini yensimbi ekhonjiwe, ikakhulukazi i-plasticity nokuqina, ukuze uthole amandla aphezulu kune-carbon steel.
I-Ductile iron castings inokusebenza okungcono kokushaqeka kune-carbon steel, kuyilapho ukukhishwa kwe-carbon steel kunokushisela okungcono kakhulu. Futhi ngokwezinga elithile, i-ductile iorn castings ingaba nokudlala okuthile kokumelana nokugqwala. Ngakho-ke i-ductile iron casting ingasetshenziselwa ezinye izindlu zamaphampu noma izinhlelo zokuhlinzeka ngamanzi. Kodwa-ke, kusadingeka senze izinyathelo zokuzivikela ekugqokeni nasekugqwaleni.
I-Ductile iron ayiyona into eyodwa kodwa iyingxenye yeqoqo lezinto ezingakhiqizwa ukuze zibe nezinhlobonhlobo zezakhiwo ngokulawula i-microstructure. Isici esivamile esichazayo saleli qembu lezinto zokwakha ukuma kwegraphite. Kuma-ayina ama-ductile, i-graphite isesimweni samaqhuqhuva esikhundleni sama-flakes njengoba isensimbi empunga. Ukuma okucijile kwama-flakes e-graphite kudala amaphuzu okugxilisa ingcindezi ngaphakathi kwe-matrix yensimbi kanye nesimo esiyindilinga samaqhuqhuva sibe sincane kakhulu, ngaleyo ndlela kuvinjwe ukudalwa kwemifantu futhi kunikeze i-ductility ethuthukisiwe enikeza ingxubevange igama layo. Ngakho-ke, uma i-iron ductile ingahlangabezana nezidingo zakho, i-iron ductile ingaba yisinqumo sakho sokuqala, esikhundleni se-carbon steel for castings yakho.
