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.
Ukadaulo wotayira thovu wotayika ndikumangirira ndikuphatikiza mitundu ya pulasitiki ya thovu yofanana kukula kwake ndi mawonekedwe ake kumagulu amitundu. Pambuyo potsuka ndi zokutira ndi kuyanika, amayikidwa mumchenga wouma wa quartz ndikugwedezeka kuti awoneke, ndipo zitsulo zamadzimadzi zimatsanuliridwa pansi pazifukwa zina. , njira ya gasifying chitsanzo ndi accupying chitsanzo udindo, kulimbitsa ndi kuziziritsa kupanga kuponyera chofunika. Pali mayina ambiri osiyanasiyana otaya thovu. Mayina akuluakulu apakhomo ndi "kuponya mchenga wouma" ndi "kuponyera kolimba kolimba", komwe kumatchedwa EPC kuponyera. Mayina akuluakulu akunja ndi awa: Njira Yotayika ya Foam (USA), P0licast Process (Italy), etc.
Poyerekeza ndi luso kuponyera chikhalidwe, anataya thovu kuponya luso ali ndi ubwino wosayerekezeka, choncho akutamandidwa monga "teknolojia kuponyera m'zaka za m'ma 21" ndi "zobiriwira kusintha makampani foundry" ndi mabwalo zoweta ndi akunja kuponyera.
Onani komwe mayankho athu angakufikitseni.
