Kupanga zamkati, monga choyimira chobiriwira chobiriwira, kumakondedwa ndi eni amtundu. Popanga zinthu zopangidwa ndi zamkati, nkhungu, monga gawo lofunikira, imakhala ndi zofunikira zaukadaulo zachitukuko ndi kapangidwe, ndalama zambiri, kuzungulira kwautali, komanso chiopsezo chachikulu. Kotero, ndi mfundo zazikulu ziti ndi zodzitetezera pakupanga nkhungu zamapulasitiki? Pansipa, tikugawana zina mwazomwe mumapangira ma phukusi kuti muphunzire ndikuwunika kapangidwe ka nkhungu zamkati.
01Kupanga Mold
Kapangidwe kameneka kamakhala ndi nkhungu yopindika, chikombole cha concave, nkhungu ya mesh, mpando wa nkhungu, chiboliboli chakumbuyo, ndi chipinda cha mpweya. Chikombole cha mesh ndicho thupi lalikulu la nkhungu. Monga nkhungu ya mauna amalukidwa kuchokera ku zitsulo kapena mawaya apulasitiki okhala ndi mainchesi 0.15-0.25mm, sangathe kupangidwa paokha ndipo ayenera kumangirizidwa pamwamba pa nkhungu kuti igwire ntchito.
Patsekeke kumbuyo kwa nkhungu ndi patsekeke wapangidwa ndi makulidwe ena ndi mawonekedwe kuti kwathunthu synchronized ndi ntchito pamwamba nkhungu, wachibale ndi nkhungu mpando. Maonekedwe a convex ndi concave ndi chipolopolo chokhala ndi makulidwe akuti khoma. The ntchito pamwamba nkhungu chikugwirizana ndi patsekeke kumbuyo ndi uniformly anagawira mabowo ang'onoang'ono.
Chikombolecho chimayikidwa pa template ya makina opangira makina kupyolera mu mpando wa nkhungu, ndipo chipinda cha mpweya chimayikidwa mbali ina ya template. Chipinda cha mpweya chikugwirizana ndi patsekeke kumbuyo, ndipo palinso njira ziwiri za wothinikizidwa mpweya ndi vacuum pa izo.
02Kupanga nkhungu
Choumba nkhungu ndi nkhungu yomwe imalowa mwachindunji pamapepala onyowa opanda kanthu pambuyo popanga ndipo imakhala ndi ntchito za kutentha, kupanikizika, ndi kutaya madzi m'thupi. Zopangidwa ndi nkhungu yojambula zimakhala ndi malo osalala, miyeso yolondola, kulimba, komanso kukhazikika bwino. Tableware zotayidwa zimapangidwa pogwiritsa ntchito nkhungu iyi. M'mafakitale, zinthu zina zazing'ono, zolondola, komanso zazikulu zimayikidwa mosanjikiza ndi wosanjikiza, ndikuyikapo zinthu zomwe zimagwiritsidwa ntchito poyika pakati pa gulu lililonse. Ngati zinthu zopangidwa ndi zamkati zimagwiritsidwa ntchito, ziyenera kupangidwa pogwiritsa ntchito nkhungu.
Komabe, zinthu zambiri zamafakitale zimagwirira ntchito mbali imodzi ndipo sizifuna kutentha. Iwo akhoza mwachindunji zouma. Mapangidwe a nkhungu yopangira mawonekedwe amaphatikiza nkhungu yowoneka bwino, nkhungu ya concave, nkhungu ya mesh, ndi chinthu chotenthetsera. Chikombole cha convex kapena concave chomwe chili ndi ma mesh chimakhala ndi mabowo otulutsa madzi. Pakugwira ntchito, pepala lonyowa lopanda kanthu limafinyidwa koyamba mkati mwa nkhungu, ndipo 20% yamadzi imafinyidwa ndikutulutsidwa. Panthawiyi, madzi omwe ali mu pepala lonyowa alibe kanthu ndi 50-55%, zomwe zimapangitsa madzi otsala pambuyo pa pepala lonyowa lopanda kanthu litenthedwa mkati mwa nkhungu kuti likhale vaporized ndi kutulutsidwa. Pepala lonyowa lopanda kanthu amalipondereza, lowumitsidwa, ndikulipanga kuti lipange chinthu.
Chikombole cha mauna mu nkhungu chimatha kuyambitsa ma mesh pamwamba pa chinthucho, ndipo nkhungu ya mauna imatha kuwonongeka mwachangu pakutulutsa pafupipafupi. Kuti athetse vutoli, wopanga nkhungu wapanga nkhungu yopanda mauna, yomwe imapangidwa pogwiritsa ntchito zitsulo zamkuwa zozungulira. Pazaka ziwiri zapitazi, patatha kusintha kwapangidwe kambiri ndikusankha kukula kwa tinthu tating'ono koyenera, moyo wa ma mesh opangidwa mwaulere amapangidwa ndi nthawi 10 kuposa nkhungu ya mauna, ndikuchepetsa mtengo wa 50%. Mapepala opangidwa amakhala olondola kwambiri komanso osalala mkati ndi kunja.
03Hot Pressing Mold
Pambuyo kuyanika, pepala lonyowa lopanda kanthu limakhala lopindika. Ziwalo zina zikasintha kwambiri kapena zimafuna kulondola kwambiri pamawonekedwe a chinthucho, chinthucho chimapangidwa ndi mawonekedwe, ndipo nkhungu yomwe imagwiritsidwa ntchito imatchedwa kuumba nkhungu. Chikombole ichi chimafunanso zinthu zotenthetsera, koma chitha kuchitika popanda nkhungu ya mauna. Zinthu zomwe zimafunikira kuumbidwa ziyenera kukhala ndi chinyezi cha 25-30% panthawi yowumitsa kuti zipangike bwino.
Pochita kupanga, zimakhala zovuta kulamulira madzi, zomwe zimapangitsa kuti zikhale zovuta kuti mankhwalawa akwaniritse zofunikira za khalidwe. Wopanga wapanga nkhungu yopangira utsi, ndipo mabowo opopera amapangidwa pa nkhungu yolingana ndi magawo omwe amafunikira kupangidwa. Pogwira ntchito, zinthuzo zimayikidwa mu nkhungu yojambula pambuyo pouma bwino. Nthawi yomweyo, dzenje lopopera pa nkhungu limagwiritsidwa ntchito popopera kutentha kukakamiza zinthu. Chikombole ichi ndi chofanana ndi chitsulo chopopera mumsika wa zovala.
04Kusamutsa Nkhungu
Kutengerako nkhungu ndiye njira yomaliza yogwirira ntchito yonseyo, ndipo ntchito yake yayikulu ndikusamutsa chinthucho mosamala kuchokera pachikombole chothandizira kupita ku thireyi yolandila. Kwa nkhungu yosamutsira, kapangidwe kake kapangidwe kake kamayenera kukhala kosavuta momwe kungathekere, kokhala ndi mabowo okokera ofananirako kuti zitsimikizire kuti chinthucho chingathe kutsatsa bwino pa nkhungu.
05Kudula Mold
Pofuna kupanga zinthu zopangidwa ndi mapepala kukhala zaukhondo komanso zokongola, zopangidwa ndi mapepala zokhala ndi mawonekedwe apamwamba zimakhala ndi njira zodulira m'mphepete. Kufa kudula nkhungu amagwiritsidwa ntchito chepetsa m'mphepete mwa zinthu zopangidwa ndi pepala, zomwe zimadziwikanso kuti zisamere m'mphepete.
