Makina opukutira m'chipinda cham'mwamba-ozizira kwambiri anayamba kupangidwa ndi kupangidwa m'ma 1920; pofika lero, zasintha pafupifupi zaka zana limodzi. M'nthawi yamakono, mapangidwe awo adakhwima komanso okhazikika, ndipo tsopano akugwiritsidwa ntchito kwambiri padziko lonse lapansi. Ngakhale makinawa amatha kupanga zitsulo zokhala ndi malo osungunuka kwambiri-monga ma aloyi amkuwa-makasitomala amayenera kusankhabe magawo enaake a kagwiridwe kake malinga ndi zomwe akufuna kupanga{6}}zigawo zotayira. Mwanjira ina, magwiridwe antchito a zida zonse, kulondola, kutulutsa mphamvu, ndi zina zotere ziyenera kutsatiridwa ndi miyezo yoyenera yaukadaulo ndi zomwe zidanenedwa.
Lero, tifotokoza njira zingapo zofunika posankha zida zotere.
1. Dziwani bwino za mitundu yosiyanasiyana ndi mawonekedwe a zida zomwe zilipo.
2. Ganizirani za mtundu wachitsulo chomwe chidzagwiritsidwe ntchito-zigawo zotayira{2}}kaya ndi chitsulo chosapanga dzimbiri, aluminiyamu, kapena zinthu zina.
3. Zipangizo zomwe zasankhidwa ziyenera kukwaniritsa zofunikira zonse zaukadaulo komanso zofunikira pakugwiritsa ntchito magawo a die-zoponya.
4. Mosasamala kanthu za mtundu wa mtundu womwe wasankhidwa, makina oponya zinthu ayenera kukhala ndi malire okwanira-potengera zinthu zofunika kwambiri, luso la kagwiridwe ka ntchito, chitetezo, ndi kagwiridwe kake ka ntchito-kuonetsetsa kuti makinawo ndi abwino komanso amapangidwa-zigawo zotayira.
5. Monga chofunikira kwambiri, kuganizira mozama za kudalirika kwa chipangizocho, chitetezo chake, komanso mtengo wake-wogwira ntchito bwino.
6. Ngati kasitomala akupanga mitundu yosiyanasiyana-yotayidwa, koma kuchuluka kwa zinthu zimene apanga pamtundu uliwonse n'kochepa, ayenera-kukwaniritsabe zomwe zalongosoledwa mu Mfundo 4-kusankhiratu makina ogwirizana ndi mfundo zake. Cholinga chake ndikusankha makina amodzi omwe angathe kukwaniritsa zofunikira zopangira magawo ambiri, potero kuchepetsa ndalama zogulira zida.
7. Pakati pazigawo zosiyanasiyana zogwirira ntchito ndi zizindikiro zaumisiri za zipangizo, chofunika kwambiri chiyenera kuperekedwa ku ntchito ya jekeseni ya makina. Poyerekeza makina amtundu wofanana kapena wofanana ndi kukula kwake, ndikofunikira kusankha mtundu womwe umapereka ntchito yayikulu kwambiri pamagawo ake a jakisoni.
Izi zikumaliza mawu athu oyamba ofunikira kusankha makina opukutira m'chipinda chozizira{0}}chamber die casting. Popeza mtundu wa zida zogulira umakhudza mwachindunji ntchito yopangira, makasitomala ayenera kuchita khama komanso kusamala posankha.
