Ngexesha lokulungiswa kokungunda
Ukunyangwa kobushushu obungafanelekanga kuya kukhokelela ekuqhekekeni komngundo kunye nokukrazulwa kwangaphambi kwexesha, ngakumbi ukuba kuphela ukucima kunye nokutshisa kusetyenziswa, ngaphandle kokucinywa, kwaye emva koko inkqubo ye-nitriding yomhlaba, ukuqhekeka komphezulu kunye nokuqhekeka kuya kwenzeka emva kwamawakawaka amaxesha okufa.
Uxinzelelo olwenziwa xa isinyithi sicinywa sisiphumo se-superposition yoxinzelelo lwe-thermal ngexesha lokupholisa kunye noxinzelelo lwesakhiwo ngexesha lokuguqulwa kwesigaba. Ukucima uxinzelelo luyimbangela yokuguqulwa kunye nokuqhekeka, kwaye kufuneka kuthotywe ukuphelisa uxinzelelo.
ngexesha lemveliso yokufa
Umngundo kufuneka ufudunyezwe kwiqondo lokushisa elithile ngaphambi kokuveliswa, ngaphandle koko, xa ubushushu obuphezulu bentsimbi etyhidiweyo buzaliswe, ukubunjwa kuya kubanda, okubangele ukwanda kweqondo lokushisa kwimigangatho yangaphakathi nangaphandle yokubumba, okukhokelela ekubeni uxinzelelo lwe-thermal, ukuqhekeka okanye ukuqhekeka kumphezulu wokubumba.
Ngexesha lenkqubo yemveliso, ubushushu bomngundo buhlala bunyuka. Xa ubushushu besikhunta bugqithisekile, kulula ukuvelisa izibonda ezinamathele, kwaye iindawo ezihambayo zihluleka ukwenza umonakalo kwi-mold surface.
Inkqubo yokulawula ubushushu bokupholisa kufuneka imiselwe ukugcina ubushushu bokusebenza kokungunda ngaphakathi koluhlu oluthile.Yintoni ukuchaneka okuphezulu
isiseko sokungunda
