Vacuum kuponyera zitsulo zopangira nyumba zamagalimoto onyamula katundu m'misika yaku Russia yokhala ndi makina a CNC ndi ntchito zopangidwa mwachizolowezi. Cast aloyi zitsulo v ndondomeko castings zikutanthauza kuponya mbali opangidwa ndindondomeko ya vacuumndi zipangizo za zitsulo zotayidwa aloyi.
Kuponyedwa kwa vacuum, kumadziwikanso kuti njira yopopera yopumira, njira yosindikizira ya vacuum, kapena njira ya V mwachidule. Uwu ndi mtundu watsopano wa njira yowonetsera thupi. Njira yowonongeka yowonongeka imagwiritsa ntchito kusiyana kwapakati pakati ndi kunja kwa nkhungu kuti imangirire mchenga wouma ndi wosasunthika pamodzi kuti upeze nkhungu ndi mawonekedwe omwe amafunidwa ndi mphamvu inayake.
Ubwino wa Vacuum Casting Process
1) Ma vacuum castings amakhala olondola kwambiri, mawonekedwe omveka bwino komanso malo osalala.
Chifukwa pamwamba pa chitsanzocho yokutidwa ndi filimu pulasitiki, palibe chifukwa kunjenjemera kapena kugogoda pamene kukoka nkhungu. Kuthamanga ndi kukakamiza koyipa kumapangitsa mchenga wowumba kukhala wophatikizika, ndipo kuuma kwa nkhungu yamchenga kumakhala kwakukulu komanso kofanana. Pansi pa kutentha kwachitsulo chosungunula, patsekeke sikophweka kupunduka. Kuphatikiza apo, kukhalapo kwa kukakamizidwa koyipa kumathandizira kudzaza kwathunthu kwachitsulo chosungunuka muchitsanzo. Pamwamba roughness wa V ndondomeko castings angafikire Ra = 25 ~ 2.5μm. The dimensional kulolerana mlingo wa castings akhoza kufika CT5 ~ CT7. Mawonekedwe amtundu wa kuponderezedwa kolakwika ndiabwino, ndipo mawonekedwe amkati ndi odalirika.
2) Palibe zomangira, madzi ndi zowonjezera mumchenga woumba, zomwe zimapangitsa kuti mchenga ukhale wosavuta.
3) Ndi yosavuta kuyeretsavacuum castings. Mipweya yocheperako imapangidwa panthawi yoponya.
4) Zida zoponyera vacuum zitha kugwiritsidwa ntchito m'mafakitale osiyanasiyana. Itha kugwiritsidwa ntchito popanga gulu laling'ono lachidutswa chimodzi komanso kupanga misa, makamaka ma castings akulu ndi apakatikati ndi ma castings okhala ndi mipanda yopyapyala ndioyenera kuponya vacuum.
