Ngati mukuganiza kuti njira yotsika mtengo kwambiri yopangira prototype ndi iti?Ndiye muyenera kuyesa vacuum casting.Mu vacuum casting, mumayenera kukhala ndi kutentha koyenera pochiritsa zinthuzo.
Kwa utomoni, mufunika madigiri 30 Celsius kuti muchepetse kutsika pa nthawi ya vacuum ya mphindi 5 ndi kutentha kwa nkhungu 60 digiri Celsius.
Kuponyera vacuum ndikofanana ndi kubwereza pogwiritsa ntchito nkhungu ya silicon.Kuponyera vacuum pulasitiki pogwiritsa ntchito nkhungu za silicon kudapangidwa m'ma 1960 m'mayunivesite aku Germany.
Kodi kuponya vacuum kumapindulitsa bwanji kampani yanu?Pitirizani kuwerenga nkhaniyi kuti mudziwe.
1. Kodi Vacuum Casting N'chiyani?
Iyi ndi njira yoponyera ma elastomers omwe amagwiritsa ntchito vacuum kukokera zinthu zilizonse zamadzimadzi mu nkhungu.Kuponyera vacuum kumagwiritsidwa ntchito pamene mpweya uli ndi vuto ndi nkhungu.
Kuonjezera apo, ndondomekoyi ingagwiritsidwe ntchito ngati pali tsatanetsatane womveka komanso mafupipafupi pa nkhungu.Komanso, amagwiritsidwa ntchito ngati zinthu zomwe zimagwiritsidwa ntchito popanga nkhungu ndi fiber kapena waya wolimbikitsidwa.
Njirayi nthawi zina imatchedwa thermoforming chifukwa ntchito yopanga imaphatikizapo kufotokoza mofulumira kumene mapepala apulasitiki amatenthedwa.Zidazi zimatenthedwa mu makina opangira vacuum mpaka zitakhala zofewa komanso zomveka.
2. Kodi Vacuum Casting Imagwira Ntchito Motani?
Kuponyera vacuum kumatsatira njira yomwe imagwiritsidwa ntchito popanga chomaliza.
• Khalani ndi Chitsanzo Chabwino Kwambiri
Njira yopangira vacuum imafuna kuti mukhale ndi mtundu wapamwamba kwambiri.Mphunzitsi wapamwamba kwambiri akhoza kukhala gawo la mafakitale palokha.Kuphatikiza apo, mutha kugwiritsa ntchito fanizo lopangidwa pogwiritsa ntchito stereolithography, yomwe ndizochitika zamapulogalamu a prototyping.
Nthawi zonse muyenera kuwonetsetsa kuti master model yomwe ikugwiritsidwa ntchito ndi yolondola komanso yowoneka bwino.Izi ndikuwonetsetsa kuti palibe zolakwika zomwe zimasamutsidwa ku chitsanzo chachitsanzo mukamaliza ndondomekoyi.
• Kuchiza Njira
Chitsanzo cha master chimakutidwa mu nkhungu ya rabara ya silicone yokhala ndi magawo awiri.Nkhungu imachiritsidwa pansi pa kutentha kwambiri kuti zitsimikizidwe kuti zigawo ziwirizo zimagwirizana.Izi zimagwiritsidwa ntchito kulimbikitsa nkhungu ndikupangitsa kuti ikhale yolimba.
Nkhungu ikachiritsidwa, imadulidwa kuti iwonetsere malo opanda kanthu pakati, omwe ali ndi miyeso yeniyeni ya chitsanzo cha master.Chikombolechi chikadulidwa pawiri, chimayikidwa m'chipinda cha vacuum.Kenako, pambuyo pake, nkhunguyo imadzazidwa ndi zinthu zomwe zasankhidwa kuti zipange chinthu.
• Kudzaza Utomoni
Muyenera kudzaza nkhungu ndi zinthu zomwe mwasankha.Utotowo umatengera mawonekedwe azinthu zamafakitale.Zinthu za utomoni nthawi zambiri zimasakanizidwa ndi ufa wachitsulo kapena utoto uliwonse kuti ukwaniritse zokongoletsa kapena zinazake zogwira ntchito.
Chikombolechi chikadzadzazidwa ndi zinthu za utomoni, chimayikidwa m'chipinda cha vacuum.Amayikidwa mu chipinda chopumulirako kuti atsimikizire kuti palibe thovu la mpweya mu nkhungu.Izi ndikuwonetsetsa kuti chomaliza sichikuwonongeka kapena kuwonongeka.
• Njira Yochiritsira Yomaliza
The utomoni amaikidwa mu uvuni kwa gawo lomaliza kuchiritsidwa.Nkhungu imachiritsidwa kutentha kwambiri kuti zitsimikizire kuti zinthuzo ndi zamphamvu komanso zolimba.Silicone nkhungu imachotsedwa mu nkhungu kuti igwiritsidwe ntchito popanga ma prototypes ambiri.
Pambuyo pochotsa chithunzicho mu nkhungu, amapaka utoto ndi kukongoletsedwa.Zojambulazo ndi zojambula zimagwiritsidwa ntchito kuti zitsimikizire kuti chinthucho chili ndi mawonekedwe omaliza.
3. Ubwino Woponya Vuto
Zotsatirazi ndi zabwino kugwiritsa ntchito vacuum casting pazinthu zobwereza.
• Kulondola Kwambiri Ndi Tsatanetsatane Wabwino Pazinthu Zomaliza
Mukamagwiritsa ntchito silicone ngati nkhungu pazinthu zanu.Zimatsimikizira kuti chomalizacho chimakhala ndi chidwi chachikulu pazambiri.Chomaliza chimatha kuwoneka ngati choyambirira.
Kusamalira tsatanetsatane kumaganiziridwa ndikuganiziridwa.Ngakhale pamene mankhwala oyambirira ali ndi geometry yovuta kwambiri, chomaliza chimawoneka ngati choyambirira.
• Ubwino Wapamwamba Wazinthu
Zopangidwa pogwiritsa ntchito vacuum casting ndi zapamwamba kwambiri.Komanso, kugwiritsa ntchito utomoni kumakupatsani mwayi wosankha zinthu zoyenera kuti mugwiritse ntchito popanga chomaliza.
Izi zimakupatsani mwayi wosankha kusinthasintha, kuuma komanso kusasunthika komwe mukufuna pazogulitsa zanu.Komanso, izi zimakhudza kwambiri mawonekedwe omaliza a chinthucho popeza zinthu zomwe zimagwiritsidwa ntchito zimakhala ndi gawo lalikulu.
• Amachepetsa Mtengo Wopanga
Kugwiritsa ntchito vacuum kuponyera kupanga mankhwala ndikosavuta.Izi ndichifukwa choti njirayo imagwiritsa ntchito silicon kupanga nkhungu.Silicone ndi yotsika mtengo poyerekeza ndi aluminiyamu kapena chitsulo ndipo imapanga zinthu zabwino zomaliza.
Kuphatikiza apo, zinthuzo zimakupatsani mwayi wopanga zinthu zambiri kuchokera ku nkhungu.Izi zimapangitsa kuti ntchitoyi ikhale yotsika mtengo poyerekeza ndi kugwiritsa ntchito makina osindikizira a 3D.
• Njira Yabwino Pamene Mukufuna Kukumana ndi Tsiku Lomaliza
Njirayi ndiyofulumira, ndipo zimatengera nthawi yochepa kuti mumalize kupanga zomaliza.Mutha kutenga masiku asanu ndi awiri kapena khumi kuti mupange pafupifupi magawo 50 ogwira ntchito.
Njirayi ndi yodabwitsa pamene mukupanga zinthu zambiri.Kuonjezera apo, ndi bwino pamene mukuyesetsa kukwaniritsa tsiku lomaliza.
4. Ntchito Za Vacuum Casting
Vacuum casting imagwiritsidwa ntchito m'makampani azakudya ndi zakumwa kupanga mabotolo ndi malata.Amagwiritsidwanso ntchito pazinthu zamalonda ndi zapakhomo.
• Chakudya ndi Zakumwa
Makampani opanga zakudya ndi zakumwa amagwiritsa ntchito mankhwalawa polemba zinthu zawo zomaliza.Kuponyera vacuum kungagwiritsidwe ntchito popanga mabotolo apulasitiki ndi malata.
Popeza njirayi ingagwiritsidwe ntchito kupanga zinthu mwachangu komanso pamlingo waukulu, imakondedwa m'mafakitale ambiriwa.
• Zamalonda
Njirayi imagwiritsidwa ntchito popanga zinthu zamalonda zomwe zingagwiritsidwe ntchito pakuyika.Zambiri mwazinthu zomwe zimapangidwa pogwiritsa ntchito njirayi ndi monga magalasi adzuwa, zikwama zam'manja, zopangira zakudya ndi zakumwa, ndi zolembera.Njira imeneyi imapanga ntchito kwa anthu omwe akufuna kuyamba kugulitsa zina mwazinthuzi.
• Zinthu Zapakhomo
Zinthu zina zapakhomo zimapangidwa pogwiritsa ntchito vacuum casting process.Zinthu zatsiku ndi tsiku monga zotsukira, kukonza chakudya, ndi zodzoladzola zimapangidwa pogwiritsa ntchito njirayi.
Ngati mutenga katundu wanu kuchokera kumakampani apamwamba, pali mwayi waukulu woti amagwiritsa ntchito njira yopangira vacuum kuti apange zinthuzo.
Pansi pa Vacuum Casting
Kuponyera vacuum ndikokwera mtengo kwambiri poyerekeza ndi kusindikiza kwa 3D kapena jekeseni woumba.Izi zimakupatsani mwayi wopanga zinthu zambiri pamtengo wotsika.
