Kugwetsazingwe zopukutirandi zomangira zapadera zomwe zimagwiritsidwa ntchito poteteza ndikuthetsa malekezero a zingwe zamawaya kapena zingwe. Izi tatifupi amapangidwa kudzera zitsulo ndondomeko amatchedwa dontho forging, imene mkangano zitsulo ndi mokakamiza anaumbidwa mu mawonekedwe ankafuna ntchito kufa kapena nkhungu pansi pa kuthamanga kwambiri.
Zotsatirazi zimakhala ndi zigawo zingapo zofunika: aShackle yooneka ngati Ukapena bawuti yokhala ndi ulusi, chishalo chomwe chimagwirizana ndi mawonekedwe a chingwe chawaya, ndi nati yomwe imamangitsa bawuti ku chishalo kuti amangirire bwino chingwe cha waya pamalo ake. Chishalocho chimapangidwa makamaka kuti chigwirizane bwino ndi chingwe cha waya, kupereka mgwirizano wamphamvu ndi wodalirika.
Kugwetsazingwe zopukutirandizofunikira m'mafakitale ambiri, zomangamanga, ndi ntchito zam'madzi momwe zingwe zamawaya zimagwiritsidwa ntchito pothandizira kapena kukweza katundu wolemetsa. Amawonetsetsa kuti chingwe cha waya chikhalabe chomangika bwino ndikuchiteteza kuti chitha kutsetsereka kapena kutsekedwa, motero kusunga chitetezo ndi kukhulupirika kwa dongosolo.
Makanemawa amapangidwa kuchokera ku zinthu zamphamvu kwambiri monga chitsulo kapena chitsulo chosapanga dzimbiri, zomwe zimatsimikizira kulimba komanso kukana kuvala ndi dzimbiri. Amapezekanso mumitundu yosiyanasiyana ndi mapangidwe kuti athe kutengera ma diameter osiyanasiyana ndi mitundu ya zingwe zamawaya.
