Ndi njira yolumikizira wothamanga wamkulu (kapena wothamanga nthambi) ndi patsekeke.Dera lodutsa panjirayo limatha kukhala lofanana ndi njira yayikulu yolumikizira (kapena njira yanthambi), koma nthawi zambiri imachepetsedwa.Chifukwa chake ndi gawo laling'ono kwambiri pamagawo onse othamanga.Maonekedwe ndi kukula kwa chipata zimakhudza kwambiri khalidwe la mankhwala.
Ntchito ya gate ndi:
A. Sinthani kuthamanga kwa zinthu:
B. Ikhoza kuteteza kubwereranso chifukwa cha kusungunuka msanga kwa kusungunuka kosungidwa mu gawo ili panthawi ya jekeseni:
C. The kudutsa kusungunula ndi pansi amphamvu kukameta ubweya kuonjezera kutentha, potero kuchepetsa kuoneka mamasukidwe akayendedwe ndi kuwongolera fluidity:
D. Ndi yabwino kulekanitsa mankhwala ndi othamanga dongosolo.Mapangidwe a mawonekedwe a chipata, kukula ndi udindo zimadalira chikhalidwe cha pulasitiki, kukula ndi kapangidwe ka mankhwala.
Maonekedwe a Cross-Sectional of Gate:
Nthawi zambiri, mawonekedwe apachipata apachipata ndi amakona anayi kapena ozungulira, ndipo malo ozungulira ayenera kukhala ochepa komanso kutalika kwake kumakhala kochepa.Izi sizongotengera zomwe zili pamwambazi, komanso chifukwa zimakhala zosavuta kuti zipata zing'onozing'ono zikhale zazikulu, ndipo zimakhala zovuta kuti zipata zazikulu zichepetse.Malo a pachipata nthawi zambiri amayenera kusankhidwa pomwe chinthucho chimakhala chokhuthala popanda kusokoneza mawonekedwe.Mapangidwe a kukula kwa chipata ayenera kuganizira za pulasitiki yosungunuka.
Cavity ndi malo opangira zinthu zapulasitiki.Zomwe zimagwiritsidwa ntchito popanga patsekeke zimatchulidwa pamodzi kuti zigawo zoumbidwa.Mbali iliyonse yopangidwa imakhala ndi dzina lapadera.Ziwalo zoumbidwa zomwe zimapanga mawonekedwe a chinthucho zimatchedwa ma concave molds (omwe amatchedwanso ma molds achikazi), omwe amapanga mawonekedwe amkati mwazopangazo (Monga mabowo, mipata, ndi zina zotero) amatchedwa ma cores kapena nkhonya (omwe amadziwikanso kuti nkhungu zachimuna). ).Popanga magawo owumbidwa, kapangidwe kake kabowo kamayenera kutsimikiziridwa molingana ndi zomwe pulasitiki, geometry yazinthu, kulekerera kwapakatikati ndi zofunikira zogwiritsidwa ntchito.Chachiwiri ndikusankha malo olekanitsa, malo a chipata ndi dzenje lotulukira ndi njira yowonongera molingana ndi dongosolo lokhazikika.
Potsirizira pake, molingana ndi kukula kwa mankhwala olamulira, mapangidwe a gawo lililonse ndi kuphatikiza kwa gawo lililonse zimatsimikiziridwa.Pulasitiki imasungunuka imakhala ndi kupanikizika kwakukulu ikalowa m'kati mwake, kotero zigawo zowumbidwa ziyenera kusankhidwa moyenerera ndikufufuzidwa kuti zikhale zolimba komanso zolimba.Pofuna kuonetsetsa kuti pulasitiki yosalala ndi yokongola kwambiri ndi yophweka, roughness ya pamwamba pokhudzana ndi pulasitiki iyenera kukhala Ra> 0.32um, ndipo iyenera kukhala yosagwira dzimbiri.Ziwalo zopangidwa nthawi zambiri zimatenthedwa kuti ziwonjezeke kuuma, ndipo zimapangidwa ndi chitsulo chosapanga dzimbiri.
