Kuponyera thovu lotayika (komwe kumadziwikanso kuti kuponya nkhungu kwenikweni) kumapangidwa ndi pulasitiki ya thovu (EPS, STMMA kapena EPMMA) polima zinthu kukhala nkhungu yeniyeni yofanana ndendende ndi kukula kwake monga zigawo zomwe ziyenera kupangidwa ndikuponyedwa, ndipo zimakutidwa. ndi zokutira zotsutsa (zolimbitsa), zosalala komanso zopumira) ndi zouma, zimakwiriridwa mumchenga wowuma wa quartz ndikutsatiridwa ndi mawonekedwe amitundu itatu. Chitsulo chosungunuka chimatsanuliridwa mubokosi la mchenga pansi pa kupanikizika koipa, kotero kuti chitsanzo cha polima chimatenthedwa ndi kusungunuka, ndiyeno chimachotsedwa. Njira yatsopano yoponyera yomwe imagwiritsa ntchito zitsulo zamadzimadzi m'malo mwa nthawi imodzi yopangira nkhungu yomwe idapangidwa pambuyo pozizira komanso kulimba kuti ipange zoponya. Kuponyera thovu kotayika kuli ndi makhalidwe awa: 1. Kuponyera ndi khalidwe labwino komanso lotsika mtengo; 2. Zida sizili zochepa komanso zoyenera kukula kwake; 3. Kulondola kwambiri, kusalala pamwamba, kuyeretsa pang'ono, ndi makina ochepa; 4. Zowonongeka zamkati zimachepetsedwa kwambiri ndipo mawonekedwe a kuponyera amakhala bwino. Zokhuthala; 5. Ikhoza kuzindikira kupanga kwakukulu komanso kochuluka; 6. Ndikoyenera kupanga misala yoponyera ma castings omwewo; 7. Ndi oyenera ntchito Buku ndi yodzichitira msonkhano mzere kupanga ndi ulamuliro ntchito; 8. Mkhalidwe wopangira mzere wopanga umakwaniritsa zofunikira zachitetezo cha chilengedwe. ; 9. Ikhoza kusintha kwambiri malo ogwirira ntchito ndi kupanga mapangidwe a mzere wopangira, kuchepetsa mphamvu ya ntchito, ndi kuchepetsa kugwiritsa ntchito mphamvu.

1. Vacuum otsika kuthamanga anataya thovu kuponya luso. Zimaphatikiza ubwino waukadaulo wa kuponyera kocheperako komanso kuponyera thovu lotayirira, kumamaliza kudzaza pansi pamphamvu ya mpweya wowongolera, ndikuwongolera kwambiri kuthekera kodzaza kwa alloy. Poyerekeza ndi kuponyera kufa, ndalama zopangira zida ndizochepa, mtengo wake ndi wochepa, ndipo ma castings amatha kulimbikitsidwa ndi chithandizo cha kutentha; Poyerekeza ndi kuponya mchenga, ma castings amakhala olondola kwambiri, osalimba kwambiri, amakhala ndi zokolola zambiri komanso amagwira ntchito bwino. Pansi pa anti-gravity, sprue imakhala njira yofupikitsa, ndipo kutaya kwa kutentha kwa kuthira kumakhala kochepa. Njira yothira ya alloy castings ndi yosavuta komanso yothandiza, yokhala ndi zokolola zambiri komanso kapangidwe kake. The chofunika kuthira kutentha ndi otsika ndi oyenera kuthira ndi kupanga aloyi zosiyanasiyana sanali ferrous. .
2.Pressure anataya thovu kuponya luso. Zimaphatikiza ukadaulo wotayira chithovu wotayika ndiukadaulo waukadaulo wolimbitsa kristalo. Mfundo yake ndikuthira zitsulo zosungunuka mu thanki yoponderezedwa ndi bokosi la mchenga kuti nkhungu ya thovu iwonongeke ndikuzimiririka, ndiyeno mwamsanga musindikize thanki yokakamiza ndikuyambitsa mpweya pazovuta zina. , kuchititsa chitsulo chosungunula kulimba ndi kunyezimira pansi pa kupanikizika. Makhalidwe a ukadaulo uwu ndikuti amatha kuchepetsa kwambiri zilema zoponya, monga shrinkage cavities, shrinkage porosity, ndi pores mu castings, kuonjezera kachulukidwe ka castings, ndikuwongolera magwiridwe antchito amawotchi. Kukhazikika pansi pa kupanikizika kwakunja kungayambitse mapindikidwe ang'onoang'ono a ma dendrites olimba, kupititsa patsogolo mphamvu ya chakudya chokwera ndikuwongolera kuchepa kwamkati kwa kuponyera. Panthawi imodzimodziyo, kupanikizika kumawonjezera kusungunuka kwa gasi muzitsulo zolimba, zomwe zimapangitsa kuti zikhale zotheka. The thovu kuchepetsedwa.
