1: Kutheni iimveliso zokubumba ngenaliti zinethambeka elitshintshayo?
Ngokubanzi, iimveliso ezibunjiweyo ngenaliti zicutshungulwa ziimolds ezifanelekileyo. Emva kokuba imveliso ebunjiweyo ngenaliti ibunjiwe kwaye inyangiwe, ikhutshwa kwi-mold cavity okanye i-core, eyaziwa ngokuba yi-demolding. Ngenxa yokuncipha kokubumba kunye nezinye izizathu, iindawo zeplastiki zihlala zibotshelelwa ngokuqinileyo kwi-core okanye zivaleleke kwi-mold cavity, njl. Emva kokuba i-mold ivuliwe, i-mold ayinakukhululwa ngokuzenzekelayo, nto leyo elula ukuba imveliso ebunjiweyo ngenaliti ikhutshwe kwi-mold kwaye ithintele umphezulu wemveliso ebunjiweyo ngenaliti ukuba ungakrweleki ngexesha lokubola. Xa uyila i-injection mold, iindawo zangaphakathi nezangaphandle zemveliso ebunjiweyo ngenaliti kufuneka zibe ne-engile efanelekileyo yokubola ecaleni kwendlela yokubola.
2: Izinto ezichaphazela ukuthambeka kokunciphisa imveliso yokubumba ngenaliti
1) Ubungakanani be-engile yokudiliza buxhomekeke ekusebenzeni kwemveliso ebunjiweyo ngenaliti, ijiyometri yemveliso, umzekelo, ukuphakama okanye ubunzulu bemveliso, ubukhulu bodonga kunye nemeko yomphezulu womngxuma, njengobunzima bomphezulu, imigca yokucubungula, njl.njl.
2) I-engile ye-draft yeplastiki eqinileyo inkulu kuneyeplastiki ethambileyo;
3) Imilo yemveliso eza kubumba ngenaliti iyinkimbinkimbi ngakumbi, okanye inxalenye yeplastiki enemingxuma emininzi yokubumba ifuna ithambeka elikhulu lokuyisusa;
4) Ukuba ukuphakama kwemveliso yokubumba ngenaliti kukhulu kwaye umngxuma unzulu, kwamkelwa ithambeka elincinci elinciphayo;
5) Ubukhulu bodonga lwemveliso yokubumba ngenaliti buyanda, amandla omngxuma ongaphakathi wokusonga umbindi mkhulu, kwaye i-engile yedrafti nayo kufuneka ibe nkulu.
