Vacuum Casting Processing Conditions
• Shandisa muchina wekukanda vacuum.
• Pisa mold pa 70 ° C (zvichida polyaddition silicon mold).
• Pisa zvikamu zvose pa 20 ° C kuitira kuchengetedza pane imwe tembiricha yakaderera.
• Weresa chikamu A mukapu yepamusoro (usakanganwa kubvumira kusara kwemarara emukombe).
Wera chikamu B mukapu yepasi (kapu yekusanganisa).
• Mushure mekuchenesa kwemaminetsi gumi pasi pekutsvaira durura chikamu A muchikamu B uye sanganisa kweminiti imwe 30 kusvika kumaminitsi maviri.
• Kanda musilicone mold, yaimbodziiswa pa70°C.
• Isa muchoto pa70°C zvishoma.
• Bvisa mushure memaminitsi makumi mana nemashanu pa70°C.
• Ita zvinotevera : 3 hr pa 70°C + 2 hr pa80°C uye 2hr pa100°C.
• Nguva dzose paunenge uchirapa, isa chikamu pachigadziko.
Kubata Chengetedzo
Hwakajairwa hutano uye kuchengetedza kunofanirwa kucherechedzwa kana uchibata izvi zvigadzirwa:
• chengetedza mhepo yakanaka
• pfeka magirovhosi uye magirazi ekuchengetedza
Kuti uwane rumwe ruzivo, ndapota tarisa kune chigadzirwa chekuchengetedza data sheet.
