Zowonongeka zodziwika bwino zimaphatikizapo kung'anima kopitilira muyeso, kufooka kapena kudulidwa, makulidwe a khoma, ngodya zopyapyala, zopindika za parison, zopindika, ming'alu, mabala akuda, mizere yakufa, kuwomba kosakwanira, kuwomba, kuphulika, kutha kwa nkhondo ndi kutayikira.
Nchiyani chimayambitsa makulidwe a khoma losafanana pakuwumba nkhonya?
Zomwe zingayambitse zimaphatikizapo malo a mbiri, kufa centering, sag ya parison, kutuluka kosasunthika kapena kukula kwa kuwombera, kuyanjanitsa nkhungu, kuzizira kosiyana komanso kuchuluka kwa kutambasula komwe kumafunidwa ndi gawo la geometry.
Kodi mumachepetsa bwanji kung'anima mu kuumba kwa extrusion?
Yang'anani koyamba komwe kung'anima kumapezeka, kulemera kwa gawo, kuyika kwa parison, kumaliza kutsekeka kwa nkhungu, kuwongolera, kuwongolera ndi kutsitsa. Konzani cholakwika chotseka kapena zida musanasinthe kulemera kwapadziko lonse lapansi.
Chifukwa chiyani pali thovu mu gawo lowumbidwa nkhonya?
Zomwe zingayambitse ndi monga condensation kapena chinyezi, gasi wotsekeka, kusakwanira kusungunula kufanana, kutayikira kwazinthu, zinthu zowonongeka ndi kuipitsidwa. Yang'anani zofunikira za utomoni ndi njira yakuthupi musanasinthe ndondomekoyi.
Kodi mapulogalamu a parison angakonze vuto lililonse la khoma?
