Vacuum castinginoreva kushandisa template yepakutanga kugadzira silicone mold mune vacuum state, uye nekuidururira nePU zvinhu muvacuum state, kuitira kutevedzera yakafanana neyekutanga template.Nekuda kwekumhanya kwayo uye mutengo wakaderera, tekinoroji iyi inoderedza zvakanyanya mutengo wekuvandudza chigadzirwa, kutenderera uye njodzi.
Zvinhu zvekugadzira silicone molds ndezvi: silicone yepamba, silicone inotengeswa kunze kwenyika, transparent silicone, uye yakakosha silicone.
Zvishandiso zvinoshandiswa muzvigadzirwa zvekubereka ndezvi: zvemumba PU, kunze kwenyika PU, pachena PU, yakapfava PU, Saigang, ABS, PP, PC, yakakwirira tembiricha inodzivirira ABS, nezvimwe.
Nzira yekugadzira yevacuum casting:
Usati wagadzira silicone mold, unofanirwa kugadzira ndiro yepakutanga, iyo inogona kugadzirwa ne cnc processing kana 3D kudhinda, uye wozotanga kugadzira silicone mold.Iyo silicone uye inoporesa mumiriri inosanganiswa zvakaenzana.Kuonekwa kweiyo mold silicone imvura inoyerera, uye iyo A chikamu chiri silicone, B chikamu chiri kurapa mumiririri.
Vacuuminguye kubvisa mabhuru emhepo: Mushure mekunge silica gel uye mumiririri wekurapa zvasangana zvakaenzana, vacuum uye bvisa mabhuru emhepo.Nguva yekutsvaira haifaniri kunge yakareba.Mumamiriro ezvinhu akajairika, haifaniri kudarika maminitsi gumi.Kana iyo nguva yekutsvaira yakarebesa, iyo silica gel inorapwa nekukurumidza.A cross-linking reaction inoitika, ichiita silicone chidimbu-ne-chidimbu, isingakwanisi kupendwa kana kudururwa.
Kubhurasha kana kuvhiya maitiro: durura silica gel yakabviswa kubva kumhepo mabhubhu pachigadzirwa nekukwesha kana kudira (Cherechedza: chigadzirwa kana modhi ichakopwa usati wadira silica gel inofanira kuburitswa nemumiriri wekuburitsa kana mumiriri wekuburitsa) , Zvadaro shandisa silica gel pane chigadzirwa.Iyo yekupfeka inofanira kunge yakaenzana.Mushure memaminitsi makumi matatu, namira chidimbu chegauze fiber weft jira kuti uwedzere kusimba uye kusimba kweiyo silica gel.
Kugadzirwa kwekunze kwekunze: nzira yakajairika uye zvinhu zvinoshandiswa ndezvekukomberedza mold nemapuranga epurasitiki kana mapuranga emapuranga, uye kuzadza mold cabinet nepurasita.Ingoisa jira regirazi fiber jira, wozopenda uye unamate, uye dzokorora maviri kana matatu akaturikidzana kuti apedze kuumbwa kwekunze kwe mold.
Nzira yekushanda yekudira kana kudira mold: kudira kana kudurura mold inoshandiswa kune zvigadzirwa zvakapfava kana zviri nyore.Iko hakuna mutsara wekuumba kuchengetedza basa uye nguva, ndiko kuti, isa chigadzirwa kana modhi yaunoda kutevedzera, uye isa vacuumed silica gel zvakananga.Dururira pamusoro pechigadzirwa, mirira kuti silica gel iome uye mold, uye wozotora chigadzirwa.(Cherechedza: Iyo perfusion mold inowanzo gadzirwa ne silica gel nekuomarara kwakapfava, kuitira kuti zvive nyore kudhiza uye kusakuvadza chigadzirwa musilicone mold).
Kana uchida kudaVacuum CastingZvikamu, tapota taura nesu zvakasununguka.
