Lost Foam Casting amatanthauza njira yoponyera yomwe imaphatikiza mawonekedwe a thovu ndi mchenga wowuma. Chitsulo chosungunuka chimadzaza mwachindunji ndikulowetsa malo omwe amapangidwa ndi nkhungu yoyambirira ya pulasitiki, ndipo amapeza mwachindunji kuponyedwa kofunikira pambuyo pozizira. The thovu chitsanzo mwachindunji vaporized pa ndondomeko zitsulo kuponyera, kotero otayika thovu kuponya sikutanthauza kuchotsedwa nkhungu. Koposa zonsezida zotayira thovu zotayika, zomwe zimagwiritsidwa ntchito kwambiri ndi polystyrene.
Masitepe aKutaya Chithovu Chotayika:
1- Gwiritsani ntchito nkhungu za thovu kuti mupange mawonekedwe a thovu ndi makina oponyera mageti
2- Gwirizanitsani mapatani ndi othamanga kuti apange moduli ya nkhungu
3- Ikirani utoto pa module
4- Yanikani utoto
5- Ikani gawolo mu bokosi la mchenga ndikudzaza ndi mchenga wouma
6- Kugwedezeka ndikugwedezeka kuti mudzaze mchenga wowuma ndikugwedeza mchengawo
7- Kuthira chitsulo chosungunula kuti chisungunuke thovu kenako ndikupanga zoponya zomwe mukufuna
8- Zoponya zikazizira, yeretsani zoponya. Mchenga wouma ukhoza kubwezeretsedwanso
Ubwino Wotaya Foam Casting:
1- Kutaya thovu ndi njira yoponyera pafupi ndi ukonde. Kulekerera kwapang'onopang'ono kwa kuponyera kumatha kufika ku CT6 ~ CT9, ndipo kuuma kwapamwamba ndi Ra = 6.3 ~ 50 μm. Maonekedwe a matope otayika amatha kufananizidwa ndi mchenga wa resin.
2- Kutayika kwa thovu kumatha kutulutsazoponyaokhala ndi mawonekedwe ovuta komanso mabowo ovuta. Poyerekeza ndi kachitidwe ka mchenga wa resin, mikangano yamchenga ikasinthidwa, m'pamenenso phindu la kutayika kwa thovu lotayika. Kupikisana pachimake cha otayika thovu kuponya ndi kupanga castings zovuta ndi cavities zovuta mkati, monga injini chipika, injini mutu ndi bokosi, etc. kuponya molondola.
3- Kutaya chithovu chotayika sikufuna kuchotsedwa kwa nkhungu, komwe kumapereka ufulu wokulirapo pakupanga mapangidwe ndi kuponya. Pankhani ya kapangidwe kake, njira yotayira thovu yotayika imayamba kugawika m'zigawo zingapo kenako ndikugawikana, kenako njira yotayika ya thovu imagwiritsidwa ntchito poponya kophatikizana, kotero kuti kuponya chithovu chotayika kumakhala ndi mwayi wopikisana ndi chikhalidwe. kuponya mchenga.
4- Kugwiritsa ntchito njira yotaya thovu yotayika kumatha kuchepetsa kuchuluka kwa ntchito, kuchepetsa kutulutsa zinyalala zolimba, ndipo mchenga wowuma womwe wagwiritsidwa ntchito utha kubwezeretsedwanso. Izi zimakwaniritsa zofunikira pakupulumutsa mphamvu ndi kuchepetsa umuna, ndipo zasintha malo ovuta omwe amaponya mchenga.
