"I-Dent" ibangelwa ukushwabana kwangaphakathi kwendawo emva kokutywinwa kwesango okanye ukungabikho kwesitofu sezinto eziphathekayo.Ukudakumba okanye ukudakumba okuncinci kumphezulu weiindawo ezibunjiweyo zesitofuyingxaki endala kwinkqubo yokubumba inaliti.
Izibonda ngokubanzi zibangelwa kukwanda kwasekhaya kwesantya sokushwabana kweemveliso zeplastiki ngenxa yokwanda kobunzima bodonga lweemveliso zeplastiki.Zinokuvela kufuphi neekona ezibukhali zangaphandle okanye ekutshintsheni ngokukhawuleza kweendonga, ezifana nomqolo we-bulges, ukuqina okanye iibheringi, kwaye ngamanye amaxesha kwiindawo ezingaqhelekanga.Oyena nobangela wezibonda kukwandiswa kwe-thermal kunye nokucutheka okubandayo kwezixhobo, kuba i-thermal coefficient yokwandisa i-thermoplastics iphezulu kakhulu.
Ubungakanani bokwandiswa kunye nokunciphisa kuxhomekeke kwizinto ezininzi, phakathi kwazo ukusebenza kweeplastiki, ubuninzi kunye nobuncinci beqondo lokushisa kunye noxinzelelo lokugcina uxinzelelo lwe-mold cavity yizona zinto zibalulekileyo.Ubungakanani kunye nokumila kweiindawo zeplastiki, kunye nesantya sokupholisa kunye nokufana zizinto ezichaphazelayo.
Ubungakanani bokwandiswa kunye nokunciphisa izinto zeplastiki kwinkqubo yokubumba ihambelana ne-coefficient yokwandisa i-thermal yeplastiki esetyenzisiweyo.I-coefficient yokwandisa i-thermal kwinkqubo yokubumba ibizwa ngokuba "i-molding shrinkage".Ngokupholisa kwe-shrinkage yecandelo elibunjiweyo, inxalenye ebunjiweyo ilahlekelwa uqhagamshelwano olusondeleyo kunye nomgangatho wokupholisa we-mold cavity.Ngeli xesha, ukusebenza kakuhle kokupholisa kuyancipha.Emva kokuba inxalenye ebunjiweyo iqhubeka ipholile, inxalenye ebunjiweyo iyaqhubeka iyancipha.Ubungakanani bokunciphisa buxhomekeke kwimpembelelo edibeneyo yezinto ezahlukeneyo.
Iikona ezibukhali kwindawo ebunjiweyo zipholile ngokukhawuleza kwaye ziqina kwangaphambili kunamanye amalungu.Indawo engqindilili ekufutshane nombindi wenxalenye ebunjiweyo ikude kakhulu kumphezulu wokupholisa womngxuma kwaye ibe yinxalenye yokugqibela yenxalenye ebunjiweyo ukukhulula ubushushu.Emva kokuba izinto ezikwiimbombo ziphilisiwe, inxalenye ebunjiweyo iya kuqhubeka iyancipha njengoko i-melted kufuphi nendawo epholileyo.Inqwelomoya phakathi kweembombo ezibukhali inokupholiswa kuphela i-unilaterally, kwaye amandla ayo angekho phezulu njengezinto eziphathekayo kwiikona ezibukhali.
Ukuphola kwemathiriyeli yeplastiki kumbindi wenxalenye kutsala umphezulu obuthathaka ngokwentelekiso phakathi kwendawo epholileyo kancinane kunye nekona ebukhali eneqondo lokupholisa elikhulu ngaphakathi.Ngale ndlela, i-dent yenziwa kumphezulu wenaliti ebunjiweyo inxalenye.
Ubukho bamazinyo bubonisa ukuba i-shrinkage yokubumba apha iphezulu kunokuncipha kweendawo ezijikelezileyo.Ukuba i-shrinkage yecandelo elibunjiweyo kwindawo enye liphezulu kunelo kwenye indawo, ke isizathu se-warpage yecandelo elibunjiweyo.Ukuxinezeleka okushiyekileyo kwi-mold kuya kunciphisa amandla empembelelo kunye nokumelana nokushisa kweendawo ezibunjiweyo.
Kwezinye iimeko, i-dent inokuphetshwa ngokulungisa iimeko zenkqubo.Ngokomzekelo, ngexesha loxinzelelo lokugcinwa kwenkqubo yecandelo elibunjiweyo, izinto zeplastiki ezongezelelweyo zifakwe kwi-mold cavity ukuhlawulela ukubunjwa kokubumba.Kwiimeko ezininzi, isango lincinci kakhulu kunezinye iindawo zenxalenye.Xa inxalenye ebunjiweyo isatshisa kakhulu kwaye iqhubeka iyancipha, isango elincinci liye laphiliswa.Emva kokunyanga, ukugcinwa koxinzelelo akunampembelelo kwinxalenye ebunjiweyo kwi-cavity.
