Chinthu chofunikira kwambiri pakugwiritsa ntchito ng'anjo yotenthetsera mpweya pogwiritsa ntchito vacuum sintering ndi kugwiritsa ntchito mpweya ndi mphamvu mopanda ndalama. Malinga ndi mitundu yosiyanasiyana ya mpweya, zinthu ziwirizi zotsika mtengo pa ntchito yotenthetsera mpweya zimatha kuwerengera 50% ya ndalama zonse. Pofuna kusunga ndalama pogwiritsa ntchito mpweya, njira yosinthira mpweya wothamanga pang'ono iyenera kukhazikitsidwa kuti zitsimikizire kuti njira zochotsera mafuta ndi zotenthetsera sizikuipitsidwa. Pofuna kuchepetsa kugwiritsa ntchito mphamvu, zinthu zotenthetsera zokonzedwa bwino zimagwiritsidwa ntchito popanga madera otentha kuti achepetse kutayika kwa kutentha. Kuti akwaniritse mfundo izi zopangidwira ndikuwongolera mtengo wa R & D mkati mwa malire oyenera, ng'anjo yamakono yotenthetsera mpweya pogwiritsa ntchito vacuum sintering idzagwiritsa ntchito zida zowerengera za hydrodynamic kuti ipeze njira yoyenera yoyendera mpweya ndi njira yoyendera kutentha.
Kugwiritsa ntchito mitundu yosiyanasiyana ya uvuni
Mosasamala kanthu za dongosolo lokonzedwa bwino komanso lapadera kwambiri, ng'anjo zambiri zotentha zomwe zili pamsika zitha kugawidwa m'zigawo monga ng'anjo ya vacuum ya periodic ndi ng'anjo ya continuous atmosphere. Zigawo zofiirira pambuyo popangira jekeseni ndi catalytic / degreasing zimakhala ndi polima yotsalira. Mitundu yonse iwiri ya ng'anjo imapereka njira yochotsera polima kutentha.
Kumbali imodzi, ndikoyenera kugwiritsa ntchito mokwanira ng'anjo yopitilira mumlengalenga ngati ndi gawo lalikulu lomwe limapanga zinthu zambiri nthawi zonse kapena mawonekedwe ofanana. Pankhaniyi, ndi nthawi yochepa komanso mphamvu yayikulu yopangira zinthu, mtengo wabwino ndi phindu zitha kupezeka. Komabe, m'mizere yaying'ono komanso yapakatikati yopanga, ng'anjo yopitilira mumlengalenga iyi yokhala ndi mphamvu zochepa pachaka za 150-200t, mtengo wokwera wolowera komanso kuchuluka kwakukulu sikotsika mtengo. Kuphatikiza apo, ng'anjo yopitilira mumlengalenga imafuna nthawi yayitali yozimitsa ntchito yokonza, zomwe zimachepetsa kusinthasintha kwa kupanga.
Kumbali inayi, ng'anjo ya vacuum sintering ili ndi ukadaulo wabwino kwambiri wowongolera njira zochotsera mafuta. Zolepheretsa zomwe zatchulidwa kale, kuphatikizapo kusintha kwa geometric ndi kuwonongeka kwa mankhwala kwa ziwalo za MIM, zitha kuthetsedwa bwino. Yankho limodzi ndikutsuka zinthu zomangira zosasunthika pogwiritsa ntchito mpweya wa laminar process kudzera mu dongosolo lolondola lowongolera mpweya. Kuphatikiza apo, pochepetsa mphamvu ya malo otentha, kutentha kwa ng'anjo ya vacuum ndikwabwino kwambiri, mpaka LK. Kawirikawiri, ng'anjo ya vacuum ili ndi ukhondo wabwino wamlengalenga, magawo osinthika a njira zophikira ng'anjo ya vacuum sintering komanso kugwedezeka pang'ono, zomwe zimapangitsa kuti ikhale chisankho chaukadaulo popanga zigawo zapamwamba (monga zida zamankhwala). Makampani ambiri amakumana ndi maoda osinthasintha ndipo amafunika kupanga zigawo zokhala ndi mawonekedwe ndi zipangizo zosiyanasiyana. Kulowetsa kochepa komanso kusinthasintha kwakukulu kwa ng'anjo ya vacuum sintering kudzawapangitsa kukhala ndi mikhalidwe yabwino. Kuyendetsa gulu la ng'anjo ya vacuum sikungopereka mizere yopangira yowonjezera, komanso kumayendetsa njira zosiyanasiyana nthawi imodzi.
Komabe, ng'anjo zina zaukadaulo zotsukira vacuum zomwe zili ndi ubwino waukadaulo zomwe zili pamwambapa zimachepa chifukwa cha mphamvu yochepa yomwe ilipo. Kuipa kwawo pakuyika-kutulutsa komanso kugwiritsa ntchito mphamvu zochepa kumapangitsa kuti mtengo wotsukira wa zida ukhale wofanana ndi mtengo wosungidwa mu MIM pr zina.
