1. Kunganciphisa kakhulu izindleko zokukhiqizwa kwe-prototype futhi kufinyeze isikhathi sokuthuthuka.
2. Izinga le-casting lihle futhi izindleko zokukhiqiza ziphansi. Inhlangano yokuqukethwe ye-casting ayiminyene futhi iziphambeko zangaphakathi zincishiswa kakhulu. Ukukhiqizwa okukhulu kanye nokukhiqizwa kwabantu abaningi kwe-casting kwenziwa futhi izindleko zincishiswa kakhulu.
I-3. Ukuphonsa okunokunemba okuphezulu okuphezulu kanye nobumba obushelelezi, okunganciphisa izindleko zokuhlanza okulandelayo kanye nemishini. Ilungele ikakhulukazi ukukhiqiza ama-castings ngokunemba okuphezulu okuphezulu, ukwakheka okuyinkimbinkimbi, kanye nemiklamo eyinkimbinkimbi. Akukho ukunqwabelana okungadingekile kwezinto ezibonakalayo ekushisweni, njenge-flash noma ama-angles asalungiswa, ukuqinisekisa ukuthi ukusakaza kungaqedwa ekuhambeni okukodwa ngokuya ngokunemba okudingekayo,
4. Kuqhathaniswa nezinye izindlela eziningi zokuphonsa, kulula futhi kusebenza kahle. Kuthuthukisa kakhulu indawo yokusebenza kanye nezimo zokukhiqiza zomugqa wokuphonsa, okwenza isikhundla sokukhiqiza sihlangabezane kangcono nezidingo zamapharamitha wezobuchwepheshe okuvikela imvelo. Inika amandla ukusebenza kwezandla kanye nokulawulwa komugqa wokukhiqiza okuzenzakalelayo. Kunciphisa ukuqina kwabasebenzi, kunciphisa ukufunwa kwabasebenzi kanye nokusetshenziswa kwamandla. Ngokwenza lula inqubo yokukhiqiza, isebenza ngempumelelo futhi inomnotho.
I-5. Isihlabathi esisetshenzisiwe singaphinde sisebenze kabusha, okuhambisana nenhloso yokuncishiswa kokuphuma kanye nokonga amandla, ukunciphisa imfucumfucu yezinto ezibonakalayo kanye nokunciphisa ukugcwala kwemfucuza
6. Izinto ezibonakalayo azilinganiselwe, kanti usayizi uyafaneleka. Ingaphonsa insimbi engagqwali, i-aluminium alloy, insimbi, i-cast aroy, ama-nickel alloy nezinye izinsimbi, futhi izingxenye ze-cast zisetshenziswa kabanzi e-motorobera, umkhumbi, ezempi, ezolimo kanye nezinye izimboni. Uhla lwesisindo lungakhiqizwa kabanzi, luze lufike ku-500 kg.
