A kupondaponda kufa, yomwe nthawi zambiri imatchedwa "kufa," ndi chida chapadera chomwe chimagwiritsidwa ntchito popanga zinthu, makamaka pa ntchito yopangira zitsulo ndi mapepala.Amagwiritsidwa ntchito popanga, kudula, kapena kupanga mapepala azitsulo m'mawonekedwe ndi makulidwe osiyanasiyana.Kupondaponda kufandi gawo lofunikira kwambiri pakupondaponda kwachitsulo, komwe kumagwiritsidwa ntchito kwambiri m'mafakitale monga magalimoto, ndege, zamagetsi, ndi kupanga zida.

Nayi kulongosola kwazinthu zazikulu za kufa kwa stamping ndi gawo lake popanga:

1. Mitundu Yakufa:
   • Blanking Die: Amagwiritsidwa ntchito podula kachidutswa kakang'ono kuchokera papepala lalikulu, kusiya mawonekedwe omwe akufuna.
   • Kuboola Imfa: Mofanana ndi kufa kosalemba kanthu, koma kumapanga dzenje kapena mabowo muzinthu m'malo modula chidutswa chonse.
   • Kupanga Die: Amagwiritsidwa ntchito kupindika, kupindika, kapena kukonzanso zinthuzo kukhala mawonekedwe kapena mawonekedwe enaake.
   • Drawing Die: Amagwiritsidwa ntchito kukoka pepala lathyathyathya kudzera pabowo kuti apange mawonekedwe atatu-dimensional, monga chikho kapena chipolopolo.
2. Zigawo za Stamping Die:
   • Die Block: Gawo lalikulu la kufa lomwe limapereka chithandizo komanso kuuma.
   • Punch: Chigawo chapamwamba chomwe chimagwiritsa ntchito mphamvu kuti chidule, kuchiumba, kapena kuchipanga.
   • Die Cavity: Chigawo chapansi chomwe chimasunga zinthuzo ndikutanthauzira mawonekedwe omaliza.
   • Ma Strippers: Zida zomwe zimathandiza kumasula gawo lomwe lamalizidwa pankhonya pambuyo pa sitiroko iliyonse.
   • Zikhomo Zowongolera ndi Zomera: Onetsetsani kuti pali kulumikizana koyenera pakati pa nkhonya ndi mphuno.

   • Mphamvu ikagwiritsidwa ntchito pa nkhonya, imatsika pansi ndikuyika mphamvu pa chinthucho, kuchititsa kuti chidulidwe, kupangidwa, kapena kupangidwa molingana ndi kapangidwe kake.
   • Njirayi nthawi zambiri imachitidwa mu makina osindikizira, omwe amapereka mphamvu yofunikira ndikuwongolera kayendetsedwe ka nkhonya.
4. Die Material:
   • Mafa amapangidwa kuchokera ku chitsulo chachitsulo kuti athe kupirira mphamvu ndi kuvala komwe kumakhudzana ndi kupondaponda.
   • Kusankhidwa kwa zinthu zakufa kumatengera zinthu monga mtundu wazinthu zomwe zikusindikizidwa, zovuta za gawolo, komanso kuchuluka komwe kukuyembekezeka.

Stamping kufa kumagwira ntchito yofunika kwambiri pakupanga zinthu zambiri, chifukwa amalola opanga kupanga zida zofananira, zapamwamba komanso zosinthika pang'ono.Mapangidwe ndi uinjiniya wa masitampu amafa ndizofunikira kuti mukwaniritse miyeso yolondola, kulolerana, ndi kumaliza kwapamwamba pazigawo zosindikizidwa.Mapangidwe othandizira makompyuta (CAD) ndi zida zoyeserera nthawi zambiri zimagwiritsidwa ntchito kukhathamiritsa mapangidwe akufa asanapangidwe.

Ponseponse, masitampu amafa ndi chida chofunikira kwambiri pakupanga kwamakono, komwe kumathandizira kupanga bwino kwazinthu zosiyanasiyana kuchokera kumitundu yosiyanasiyana yazitsulo ndi zida zina.
