(1) Amanqaku aphambili kuyilo lwendlela ehamba phambili yokuchanekaisitofu sokungunda
Ububanzi bomzila oyintloko wokuhamba buchaphazela uxinzelelo, izinga lokuhamba kunye nexesha lokuzalisa i-mold yeplastiki etyhidiweyo ngexesha lokutofa.
Ukwenzela ukuba kube lula ukusetyenzwa kokungunda okuchanekileyo kwesitofu, eyona ndlela iphambili yokuqukuqela ayenziwa ngokuthe ngqo kumngundo, kodwa kusetyenziswa umkhono we-sprue.Ngokubanzi, ubude bomkhono wesango kufuneka bube bufutshane kangangoko kunokwenzeka ukuphepha ilahleko yoxinzelelo olugqithisileyo kwiplastiki etyhidiweyo kunye nokunciphisa i-scrap kunye neendleko zokuvelisa.
(2) Amanqaku aphambili ekuyilweni kwee-manifolds zokubumba ngokuchaneka kwenaliti
Inaliti yokubumba echanekileyo ingumjelo weplastiki etyhidiweyo yokungena kumgodi wokungunda ngokutyibilikayo ngotshintsho kwicandelo elinqamlezayo kunye necala lomjelo wokuhamba.
Amanqaku aphambili oyilo oluninzi:
①Indawo enqamlezileyo ye-manifold kufuneka ibencinci kangangoko phantsi kwemeko yokuba idibana nenkqubo yokubumba inaliti yenaliti echanekileyo yokungunda.
②Umgaqo wokusasazwa kwezinto ezininzi kunye ne-cavity yilungiselelo elihlangeneyo, umgama ofanelekileyo kufuneka usetyenziswe i-axisymmetric okanye i-symmetric yeziko, ukwenzela ukuba ibhalansi yomjelo wokuhamba, kangangoko kunokwenzeka ukunciphisa indawo epheleleyo yendawo yokubumba.
③ Ngokubanzi, ubude bezinto ezininzi kufuneka bube bufutshane kangangoko.
④Inani lokujika kuyilo lwe-manifold kufuneka libembalwa kangangoko, kwaye kufuneka kubekho inguqu egudileyo ekujikeni, ngaphandle kweekona ezibukhali.
⑤Uburhabaxa bomphezulu jikelele bomphezulu wangaphakathi we-manifold kufuneka bube yi-Ra1.6.
