Stopcock mold ndi chida chomwe chimagwiritsidwa ntchito popanga kupanga ma stopcocks, omwe ndi ma valve omwe amagwiritsidwa ntchito kuwongolera kutuluka kwa zakumwa kapena mpweya pakugwiritsa ntchito zosiyanasiyana, monga zida zamankhwala kapena zida za labotale.Nazi njira zitatu zomwe nkhungu ya stopcock imagwirira ntchito: Kupanga kwa Nkhungu ndi Kupanga Kwa Cavity: Nkhungu ya stopcock idapangidwa kuti ipange mawonekedwe ofunikira ndi magwiridwe antchito a stopcock.Amakhala ndi matheka awiri kapena kuposerapo, omwe nthawi zambiri amapangidwa ndi chitsulo, omwe amasonkhana pamodzi kuti apange phawo limodzi kapena angapo pomwe jekeseni yosungunukayo imapangidwa.Mapangidwe a nkhungu amaphatikizapo zinthu zofunika, monga madoko olowera ndi kutuluka, malo osindikizira, ndi njira zowongolera, kuti zitsimikizire kuti stopcock ikugwira ntchito bwino.Injection ya zinthu zosungunula: Chikombolechi chikakhazikitsidwa ndikutsekedwa bwino, zinthu zosungunuka, zomwe zimakhala ndi Thermoplastic kapena elastomeric material, amabayidwa m'mabowo pansi pa kupsyinjika kwakukulu.Jakisoniyo amapangidwa pogwiritsa ntchito makina apadera, monga makina opangira jakisoni, omwe amakakamiza zinthuzo kudzera munjira ndi kulowa m'miyendo ya nkhungu.Zinthuzo zimadzaza zibowo, kutenga mawonekedwe a kamangidwe ka stopcock. Kuzizira ndi Kutulutsa: Zinthu zosungunula zikatha kubayidwa mu nkhungu, zimasiyidwa kuti zizizizira ndi kulimba.Kuziziritsa kumatha kuthandizidwa pozungulira choziziritsa kukhosi kudzera mu nkhungu kapena kugwiritsa ntchito mbale zozizirira.Zinthuzo zikalimba, nkhungu imatsegulidwa, ndipo stopcock yomalizidwa imatulutsidwa m'mabowo.Kutulutsa kumatha kutheka kudzera m'njira zosiyanasiyana, monga ma ejector pin kapena kuthamanga kwa mpweya.Njira zoyendetsera khalidwe labwino, kuphatikizapo kuyendera zolakwika ndi kulondola kwazithunzi, zikhoza kuchitika panthawiyi kuti zitsimikizire kuti stopcock ikukwaniritsa zofunikira.Nkhungu imalola kupanga koyenera komanso kosasinthasintha kwa stopcocks, zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana pakugwiritsa ntchito kuwongolera madzimadzi.
