Waliwo ebika bingi eby'ebyuma ebifa-, nga byawulwamu ebika by'ebisenge ebibuguma-ebinyogovu n'ebinyogovu-okusinziira ku nkola zaabyo-okusuula. Ebyuma ebikuba ebinyogovu (Cold-Camber Die-Ebyuma ebisala ebimera byettanira nnyo bakasitoma olw'engeri gye bakozesaamu emirimu egy'enjawulo n'okukola obulungi. Bakasitoma bangi basanga emiguwa gya ffeeza nga girabika mu bitundu ebisuuliddwa mu kiseera ky’okufa-ekizisobera. Bino wammanga bye binnyonnyola ensonga.
Ebyuma ebikuba ebinyonyi ebinyogovu-ebifa-Ebitundu by’ebintu birina ebitundu bingi, ebikoleddwa mu bintu eby’enjawulo. Mu kiseera ky’okussaako, abakola ebyuma balina okulowooza ku ngeri y’ebyuma okutwalira awamu. Ebitundu ebirina obuziyiza bw’ebbugumu obubi bitera okukwatibwa ensonga z’omutindo mu kiseera ky’okufa-okusuula, kale ebitundu bino ebitali ku mutindo birina okukyusibwa naddala mu bintu, kubanga obuveera bwe businga ebbugumu-okugumira.
Silver streaks nazo zisobola okubaawo singa ekiveera ekiyingira mu kitundu kino kiba kinene nnyo oba kitono nnyo. Ensonga zino zeetaaga okulongoosa mu kiseera ky’okukuŋŋaanya, era enkola esinga obulungi kwe kutereeza okulungamya kw’omulyango oguyingira mu pulasitiika. Singa wabaawo amazzi mu kintu, ebitundu byonna eby’ekisenge ekinyogovu bifa-ekyuma ekikuba ebisale kiteekwa okukalizibwa.
Ekyuma bwe kiba nga kidduka mangu nnyo, kiteekwa okukendeezebwa. Singa wabaawo ggaasi mu ppipa, omuwendo gw’amazzi agakulukuta mu koloyidi gulina okukendeezebwa mpola.
Singa ekisenge ekinyogovu kifa-Okufulumya empewo mu kyuma ekikuba ebyuma kibeera kibi, kisaana okulongoosebwa mu ssaayansi. Singa omuwendo omunene ogw’ebintu ebiwedde byeyolekera mu kiseera ky’okukola, birina okukendeezebwa. Singa ebbugumu ku kifo ekigguka liba ddene nnyo, ebyuma bya firiigi birina okukozesebwa okukendeeza ku bbugumu.
Waliwo ensonga nnyingi eziviirako emiguwa gya ffeeza mu bitundu ebisuuliddwa ebyuma ebinyogovu ebifa-ebyuma ebikuba ebisale. Mu kukola ddala, ebizibu bino bwe bibaawo, birina okutunulwamu mu bya ssaayansi okulongoosa omutindo gw’ebitundu ebifa-Ebitundu ebibuuziddwa.
