Umgangatho wokungunda sisiseko seemveliso zeplastiki eziqeqeshiweyo.Kwaye uyilo lokungunda sisiseko sokwenziwa komgangatho ophezulu wokubumba.Nazi izinto ezi-5 ekufuneka sinikele ingqalelo kuzo xa sisenza uyilo lokungunda oluchanekileyo.

1. Khangela umzobo wenxalenye kwaye uqinisekise isikhokelo sokuvula i-mold kunye nendawo yomgca wokuhlukanisa.Imveliso yeplastiki nganye idinga ukumisela isikhokelo sayo sokuvula umngundo kunye nomgca wokwahlula ekuqaleni koyilo lokungunda ukunciphisa izilayidi okanye iziphakamisi ukwenza okona kulungileyo ukuthintela impembelelo yomphezulu wokuthambisa obangelwa yimigca yokwahlulahlula.Emva kokumisela isikhokelo sokuvula i-mold, zama okusemandleni ukwenza iimbambo zemveliso, iziqeshana, iiprotrusions kunye nezinye izakhiwo ezihambelanayo zinokuhambelana nesikhokelo sokuvula i-mold.Kule meko, kunokunceda ukuphepha ukutsalwa okungundoqo, ukunciphisa imigca edibeneyo, kunye nokwandiswa kwexesha lokubumba.Okwangoku, umgca wokuhlukana ofanelekileyo unokukhethwa ukuze ugweme i-undercut enokwenzeka kwindlela yokuvula i-mold, oku kunokuphucula ukubonakala kwenxalenye kunye nokusebenza kobumba.

2. Xa uhlola iinxalenye zomzobo, senza i-DFM kubathengi kwaye sinikeze isiphakamiso se-angle yedrafti kwinxalenye.Lungisa i-engile eyidrafti ngokufanelekileyo kuya kunceda ukunqanda iingxaki ezinokuthi zibekho njengophawu lokutsala, i-deformation kunye nokuqhekeka.Xa usenza uyilo lokungunda kunye nesakhiwo sokufaka umngxuma onzulu, i-engile eyidrafti yomphezulu wangaphandle kufuneka ibe nkulu kune-engile eyidrafti yomgangatho wangaphakathi ukunqanda ukuncamathela kumngxuma (ukugcina amalungu kwicala elingundoqo), kwaye uqinisekise ubukhulu bodonga lwemveliso efanayo, qinisekisa amandla ezinto eziphathekayo kunye nexesha lokuvula.

3. Amalungu ePlastiki ubukhulu bodonga yenye yezinto ezibalulekileyo kwizixhobo zeplastiki.Ngokuqhelekileyo, xa ubukhulu bodonga bungaphezulu kwe-4mm, kuya kubangela ingxaki yokushwabana okukhulu, ukuguqulwa kunye nomgca we-welding kwiindawo kwaye kufuna ixesha elide lokupholisa kwinkqubo yokubumba inaliti.Kule meko, kufuneka sicinge ngokutshintsha isakhiwo senxalenye yeplastiki.Ngamanye amaxesha, singongeza iimbambo ukomeleza amandla enxalenye kunye nokunciphisa ukuba nokwenzeka kokonakala.

4. Inkqubo yokupholisa ngundo yinto eyingozi kakhulu ekufuneka siyiqwalasele xa kusenziwa uyilo lokungunda.Ukupholisa kuya kuba nempembelelo enkulu yexesha lomjikelo wokubumba kunye nomngcipheko wokuguqulwa kwamalungu.Uyilo olulungileyo lwejelo lokupholisa lunokunceda ukunciphisa ixesha lomjikelo wokubumba, ukuhlehlisa ubomi bokubumba kunye nokunciphisa umngcipheko wokuguquka kwelungu elibunjiweyo.

5. Indawo yesango nayo ibaluleke kakhulu.Ichaphazela umphezulu wezinto zokuthambisa wenxalenye, umngcipheko wokuguqulwa, uxinzelelo lwenaliti, ixesha lokubumba umjikelo, kwaye ukuba umxhasi ufuna imbaleki inokunqunyulwa ngokuthe ngqo emva kokubumba ukonga iindleko zabasebenzi, isango elikhethiweyo kufuneka liqwalaselwe.
