Pankhani ya nkhungu, nthawi zambiri anthu amagwirizanitsa nkhungu zoponyedwa ndi kufajekeseni nkhungu, koma kwenikweni kusiyana pakati pawo kudakali kwakukulu kwambiri. Monga kuponyera kufa ndi njira yodzaza nkhungu ndi chitsulo chamadzimadzi kapena theka-lamadzi pamlingo wokwera kwambiri ndikulilimbitsa mokakamizidwa kuti mupeze kuponyera kufa. Nthawi zambiri amagwiritsidwa ntchito muzitsulo, pamene jekeseni ndi kuumba jekeseni, njira yaikulu yopangira thermoplastic, thermoplastic imapangidwa ndi utomoni wa thermoplastic, womwe ukhoza kutenthedwa mobwerezabwereza kuti ufewetse ndi kukhazikika kuti ukhale wolimba, ndondomeko ya thupi, yosinthika, kutanthauza kuti ikhoza kukhala amagwiritsidwa ntchito ngati pulasitiki yobwezerezedwanso.
Kusiyana pakati pa nkhungu zoponya kufa ndi pulasitiki.
1. Kuthamanga kwa jekeseni wa nkhungu zoponyera kufa ndipamwamba, kotero zofunikira za template zimakhala zokhuthala kuti zisawonongeke.
2.Chipata cha nkhungu zoponyera kufa ndizosiyana ndi zowonongeka za jekeseni, zomwe zimafuna kupanikizika kwakukulu kuti achite chododometsa kuti awononge kutuluka kwa zinthu.
3.Kufa-kuponyera nkhungu sikuyenera kuzimitsa kernel yakufa, chifukwa kutentha mkati mwa nkhungu kumapitirira madigiri 700 pamene kufa-kuponyedwa, kotero kuumba kulikonse kumakhala kofanana ndi kuzimitsa kamodzi, nkhungu imakhala yovuta kwambiri, pamene jekeseni wamba ayenera kuzimitsidwa ku HRC52 kapena kuposa.
4.Die-casting nkhungu kawirikawiri patsekeke kuti mankhwala nitriding, kuteteza aloyi zomata pabowo.
5.Kawirikawiri kufa-kuponya nkhungu ndi zikuwononga kwambiri, pamwamba pamwamba zambiri buluu mankhwala.
6.Poyerekeza ndi nkhungu za jekeseni, zojambulajambula zakufa zimakhala ndi chilolezo chokulirapo cha magawo osunthika (monga slider core), chifukwa kutentha kwakukulu kwa njira yopangira kufa kudzachititsa kuti kutentha kuwonongeke. Ngati chilolezocho chili chaching'ono kwambiri, chimapangitsa nkhungu kugwidwa.
7. Polekanitsa nkhungu yakufa yokhala ndi zofunikira zina zapamwamba, chifukwa madzi a aloyi ndi abwino kwambiri kuposa pulasitiki, kutentha kwambiri komanso kuthamanga kwa zinthu kuchokera pamalo olekanitsa kumawulukira koopsa kwambiri.
8. jekeseni nkhungu zambiri zimadalira zikhomo ejector, malo olekanitsa, etc. akhoza kutopa, nkhungu kufa-ponyera ayenera kutsegula utsi grooves ndi kutolera matumba slag (kusonkhanitsa ozizira zinthu mutu).
9. Kuumba mosagwirizana, kufa-kuponya nkhungu jekeseni liwiro, gawo la jekeseni kuthamanga. Mbewu za pulasitiki nthawi zambiri zimabayidwa m'magawo angapo, kugwira ntchito.
10. Die-ponyera zisamere nkhungu awiri mbale nkhungu kamodzi lotseguka nkhungu, pulasitiki nkhungu osiyana mankhwala dongosolo si chimodzimodzi.
Komanso, zisamere pachakudya pulasitiki ndi kufa-kuponya zisamere pakupanga zitsulo ndi osiyana; nkhungu za pulasitiki zimagwiritsidwa ntchito S136 718 NAK80, T8, T10 ndi zitsulo zina, pamene nkhungu zoponyera ufa zimagwiritsidwa ntchito makamaka 3Cr2, SKD61, H13 zitsulo zosagwira kutentha.
