I-Gray cast iron investment castings iwukubunjwa okunembayo okukhiqizwa inqubo yokusakazwa kwe-wax elahlekile eyenziwe ngensimbi empunga. Kwa-RMC Foundry, singahlinzeka ngezinsizakalo ezenziwe ngokwezifiso ezenziwe ngomthungi kanye nezinsizakalo zemishini ye-CNC ngokwemidwebo yakho, ukusetshenziswa kanye nezidingo.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-Grey cast iron casting imvamisa ikhiqizwa inqubo yokusakazwa kwesihlabathi, nokho, kwezinye izinto ezidinga ukunemba okunembayo kanye nesakhiwo esiyinkimbinkimbi,inqubo yokutshala imalifuthi kuyisinqumo esihle.

Lapho siphonsa insimbi empunga, silandela ngokuqinile ukwakheka kwamakhemikhali kanye nezakhiwo zemishini ngokuya nge-stardards noma izidingo ezivela kumakhasimende. Ngaphandle kwalokho, sinekhono nemishini yokuhlola ukuthi kukhona yini ukonakala kokuphonsa ngaphakathi kwezihlabathi ezimpunga zensimbi.

Nakuba izinsimbi ezisansimbi zingaba nephesenti lekhabhoni phakathi kuka-2 kuya ku-6.67, umkhawulo osebenzayo uvamise ukuba phakathi kuka-2 no-4%. Lezi zibalulekile ikakhulukazi ngenxa yezimfanelo zazo ezinhle kakhulu zokulingisa. I-iron empunga ishibhile kune-iron ductile, kodwa inamandla aphansi kakhulu okuqina kanye ne-ductility kune-ductile iron. I-iron empunga ayikwazi ukuthatha indawo yensimbi ye-carbon, kuyilapho i-iron ductile ingase ithathele insimbi ye-carbon esimweni esithile ngenxa yamandla aphezulu aqinile, amandla okukhiqiza kanye nokwelula kwe-iron ductile.

Ukutshala imali (i-wax elahlekile) kuyindlela yokunemba yokuphonsa imininingwane yomumo we-net-net usebenzisa ukuphindaphinda kwamaphethini we-wax. Ukufakwa kwe-investimenti noma i-wax elahlekile kuyinqubo yokuphonsa kwensimbi ngokuvamile esebenzisa iphethini ye-wax ezungezwe igobolondo le-ceramic ukwenza isikhunta se-ceramic. Lapho igobolondo loma, ingcina iyancibilika, kusale isikhunta kuphela. Khona-ke ingxenye yokuphonsa ikhiwa ngokuthululela insimbi encibilikisiwe esikhunjini se-ceramic.

I-silica sol casting process iyinqubo eyinhloko yokufaka utshalomali ye-RMC investing Foundry. Besilokhu sakha ubuchwepheshe obusha bezinto zokunamathela ukuze sifinyelele izinto zokunamathela ezinokonga kakhulu futhi ezisebenzayo ukuze kwakhiwe igobolondo le-slurry. Kuwumkhuba omangalisayo ukuthi inqubo ye-Silica sol casting ingena esikhundleni senqubo yengilazi yamanzi esezingeni eliphansi, ikakhulukazi yokusakazwa kwensimbi engagqwali kanye nokusakazwa kwensimbi yengxubevange. Ngaphandle kwempahla yokubumba esunguliwe, inqubo ye-silica sol casting nayo iye yasungulwa ukuze izinze futhi ikhulise ukushisa okuncane.
