Zipangizo zomwe zimagwiritsidwa ntchito popangama dies opondapondakuphatikizapo chitsulo, carbide yopangidwa ndi simenti yachitsulo, carbide, zinc alloys, zinthu za polima, aluminiyamu bronze, ma high and low melting point alloys ndi zina zotero. Zipangizo zambiri zomwe zimagwiritsidwa ntchito popanga ma stamping dies makamaka ndi chitsulo. Mitundu yodziwika bwino ya zipangizo zomwe zimagwiritsidwa ntchito pazinthu zogwirira ntchito za ma dies ndi: chitsulo cha carbon tool, chitsulo cha low alloy tool, chitsulo cha chromium cha carbon high kapena medium tool, chitsulo cha carbon alloy cha medium, chitsulo chothamanga kwambiri, chitsulo cha matrix ndi carbide, chitsulo cha cemented carbide, ndi zina zotero.

1. Chitsulo chopanda zida zambiri

Chitsulo cha zida zotsika mtengo chimachokera ku chitsulo cha zida za kaboni chomwe chimawonjezera kuchuluka koyenera kwa zinthu zosakaniza. Poyerekeza ndi chitsulo cha zida za kaboni, chimachepetsa chizolowezi cha kusweka ndi kuzima, chimawonjezera kulimba kwa chitsulo, komanso kukana kuwonongeka ndikwabwino. Chitsulo chotsika mtengo chomwe chimagwiritsidwa ntchito popanga nkhungu ndi CrWMn, 9Mn2V, 7CrSiMnMoV (code CH-1), 6CrNiSiMnMoV (code GD) ndi zina zotero.

2. Chitsulo cha kaboni

Kugwiritsa ntchito kwambiri mu chikombole cha chitsulo cha kaboni cha T8A, T10A, ndi zina zotero, ubwino wa ntchito yabwino yokonza, wotsika mtengo. Koma kuuma kwake ndi kufiira kwake n'koipa, kusintha kwa kutentha, komanso mphamvu yake yonyamula katundu ndi yochepa.

3. Chitsulo chothamanga kwambiri

Chitsulo chothamanga kwambiri chili ndi kuuma kwakukulu, kukana kuwonongeka ndi mphamvu yopondereza ya chitsulo cha nkhungu, mphamvu yonyamula katundu wambiri. Zomwe zimagwiritsidwa ntchito kwambiri mu nkhungu ndi W18Cr4V (khodi 8-4-1) ndi tungsten yochepa W6Mo5Cr4V2 (khodi 6-5-4-2, mtundu wa United States M2) komanso kukonza kulimba kwa chitukuko cha chitsulo chochepetsedwa cha carbon vanadium chitsulo chothamanga kwambiri 6W6Mo5Cr4V (khodi 6W6 kapena kaboni wotsika M2). Zitsulo zothamanga kwambiri zimafunikanso kupangidwanso kuti ziwongolere kufalikira kwa carbide.

4. Zitsulo za zida zapakati-chromium zokhala ndi mpweya wambiri

Zitsulo za zida zapakati-chromium zokhala ndi kaboni wambiri zomwe zimagwiritsidwa ntchito popanga nkhungu ndi Cr4W2MoV, Cr6WV, Cr5MoV, ndi zina zotero, kuchuluka kwa chromium m'thupi lawo ndi kochepa, carbide yochepa ya eutectic, kugawa kwa carbide, kusintha kwa kutentha ndi kochepa, ndi kuuma bwino komanso kukhazikika kwa mawonekedwe. Poyerekeza ndi kugawa kwa carbide, chitsulo cha chromium chokhala ndi kaboni wambiri chakhala chachikulu, magwiridwe antchito ake asintha.

5. Chitsulo cha zida chokhala ndi chromium yambiri chokhala ndi mpweya wambiri

Chitsulo cha zida cha chromium chokhala ndi kaboni wambiri chomwe chimagwiritsidwa ntchito kwambiri ndi Cr12 ndi Cr12MoV, Cr12Mo1V1 (code D2), chili ndi kulimba bwino, kulimba komansokukana kuvala, kusintha kwa kutentha kwa mankhwala ndi kochepa kwambiri, chifukwa cha chitsulo cha nkhungu cholimba kwambiri, chomwe chili ndi mphamvu yonyamula katundu yachiwiri kuposa chitsulo champhamvu kwambiri. Koma kusiyanitsa kwa carbide ndi kwakukulu, kuyenera kusinthidwa mobwerezabwereza (kusokoneza kwa axial, kujambula kwa radial) kuti musinthe forging, kuti muchepetse kusalingana kwa carbide, ndikuwongolera magwiridwe antchito.

6. Carbide yopangidwa ndi simenti ndi carbide yopangidwa ndi simenti yachitsulo

Kulimba ndi kukana kwa carbide yopangidwa ndi simenti ndi kwakukulu kuposa kwa chitsulo china chilichonse cha nkhungu, koma mphamvu yopindika ndi kulimba kwake ndi kochepa. Carbide yopangidwa ndi simenti yomwe imagwiritsidwa ntchito popanga nkhungu ndi tungsten ndi cobalt, ndipo popanga nkhungu zomwe zimakhala ndi mphamvu zochepa komanso zosafunika kwambiri, mungagwiritse ntchito carbide yopangidwa ndi simenti yochepa. Pa nkhungu zomwe zimakhala ndi mphamvu zambiri, carbide yokhala ndi cobalt yambiri ingagwiritsidwe ntchito.
