1. Kutheni iimveliso ezibunjiweyo ngenaliti zine-engile ejikelezayo?
Ngokubanzi, iimveliso ezibunjiweyo ngenaliti kufuneka zicutshungulwe ngee-molds ezifanelekileyo. Emva kokuba imveliso ebunjiweyo ngenaliti ibunjiwe kwaye inyangiwe, ikhutshwa kwi-mold cavity okanye i-core, eyaziwa ngokuba yi-demolding. Ngenxa yokuncipha kwe-molding kunye nezinye izizathu, iindawo zeplastiki zihlala zijikelezwe kwi-core okanye zivaleleke kwi-mold cavity. Emva kokuba i-mold ivuliwe, i-mold ayinakukhutshwa ngokuzenzekelayo, nto leyo eyenza kube lulaukubumba ngenaliti imveliso ukuba iphume kwisikhunta kwaye ithintele umphezulu wemveliso efakwe kwi-injection ukuba ungakrweleki ngexesha lokuyila. Xa uyila isikhunta se-injection, umphezulu wangaphakathi nowangaphandle we-injection pro
umbhobho kufuneka ube ne-engile efanelekileyo yokudiliza kwicala lokudiliza.
2.Izinto ezichaphazela ubungakanani be-engile yokudiliza yeemveliso ezibunjiweyo ngenaliti
1) Ubungakanani be-engile yokudiliza buxhomekeke ekusebenzeni kwemveliso ebunjiweyo ngenaliti kunye nejometri yemveliso, umzekelo, ukuphakama okanye ubunzulu bemveliso, ubukhulu bodonga kunye nemeko yomphezulu womngxuma, njengobunzima bomphezulu, imigca yokucubungula, njl.njl.
2) Iplastiki eqinileyo ine-engile enkulu kuneplastiki ethambileyo;
3) Imilo yemveliso eza kubumba ngenaliti iyinkimbinkimbi ngakumbi, okanye inxalenye yeplastiki enemingxuma emininzi yokubumba ifuna i-engile enkulu yokuyisusa;
4) Ukuba ukuphakama kwemveliso ebunjiweyo ngenaliti kukhulu kwaye umngxuma unzulu, kokukhona i-engile yokususa i-demoulding incinci;
5) Ubukhulu bodonga lwemveliso ebunjiweyo ngenaliti buyandiswa, amandla omngxuma ongaphakathi wokuqinisa umbindi mkhulu, kwaye i-engile yedrafti kufuneka ibe nkulu.
