Kenyelletso ea Vacuum Casting
Sesebediswa sa vacuum casting se sebetsang ka ho putlama ha sekoti, Theknoloji ea vacuum casting e sebelisang prototype (SLA laser rapid prototyping piece, CNC products) ho etsa hlobo ea silicone ka tlas'a vacuum, 'me e tšeloa tlas'a maemo a vacuum, joalo ka ABS,PU jj. Vacuum casting e boetse e sebelisoa ho etsisa mohlala kapa ho kopitsa sengoathoana.
E na le mefuta e fapaneng e kenyelletsang: Vacuum Mold Casting, Vacuum Pressure Casting, Vacuum Sand Casting joalo-joalo.Mokhoa ona o loketse ka ho khetheha bakeng sa tlhahiso ea lihlopha tse nyenyane.Ke tharollo e theko e tlase ho rarolla tlhahiso ea liteko le tlhahiso ea li-batch tse nyane ka nako e khuts'oane, hape e ka kopana le bopaki ba tlhahlobo ea ts'ebetso ea disampole tse ling tse rarahaneng tsa boenjiniere.
Mona ke kamoo e sebetsang kateng.
Mokhoa ona o qala ka ho beha hlobo ea silicone e nang le likarolo tse peli ka kamoreng ea vacuum.Thepa e tala e kopantsoe le degassing 'me e tšeloa ka har'a hlobo.Ka mor'a moo, khase e ntšoa hore e hloekisoe ebe hlobo e ntšoa ka phaposing.Qetellong, ho lahla ho phekoloa ka ontong 'me hlobo e tlosoa ho lokolla ho lahla ho felile.Mefuta ea silicone e ka sebelisoa hape.Ho bopa ha silicone ho fella ka likarolo tsa boleng bo holimo tse bapisoang le likarolo tse entsoeng ka ente.Sena se etsa hore mefuta ea vacuum casted e tšoanelehe ka ho khetheha bakeng sa tlhahlobo ea ho lekana le ho sebetsa, merero ea ho bapatsa kapa letoto la likarolo tsa ho qetela ka bongata bo lekanyelitsoeng.
Melemo
- Theko e tlaase, 'me potoloho ea tlhahiso ea lihlahisoa e batla e le khutšoanyane.Ho na le likhechana tse nyane mme litšenyehelo tsa mochini li tlase haholo ho feta mochini oa CNC le khatiso ea 3D.
- E loketse ho sebetsa le ho hlahisa lihlahisoa tse nyenyane tsa lihlahisoa.Ka mor'a ho etsa phetolelo ea pele, e ka kopitsoa ho latela phetolelo ea pele.Leha ho le joalo, machining CNC hloka lathes ho etsa prototypes ka bonngoe.
- Ts'ebetso e ntle ea ho bopa.Mefuta e bonolo ka mor'a ho folisa le ho bōptjoa kaofela e pepenene kapa e feto-fetoha, e na le matla a matle a tsitsitseng, a loketseng ho itšeha le ho arohana.
- Monyetla oa ho hloleha ha ts'ebetso o nyane.Ha feela ho se na bothata ka ea pele, replica ka tlhaho e ke ke ea fosa.
- Ho pheta-pheta hantle.Silicone e sebelisetsoang ho bopa e na le mokelikeli o motle pele o phekoloa, 'me ka vacuum defoaming, sebopeho se qaqileng le mokhabiso oa mohlala li ka bolokoa ka nepo.
Mefokolo
- Ho bonolo ho fokotseha le ho holofala, hobane e tla fokotseha ka mor'a hore e futhumale ka mocheso o phahameng ebe e pholile, e leng se hlahisang deformation.Phoso e akaretsang e ka ba 0.2mm.
- Ka kakaretso, prototype ea "vacuum compound" e ka mamella mocheso o phahameng oa likhato tse ka bang 60, 'me matla le boima ba eona li tlase ho feta tsa mohlala oa CNC.
Liindasteri tse nang le Vacuum Casting
● ABS: E tšoeu, e mosehla o khanyang, e ntšo, e khubelu.● PA: E tšoeu, e mosehla o khanyang, e ntšo, e putsoa, e tala.● PC: E bonaletsang, e ntšo.● PP: E tšoeu, e ntšo.● POM: E tšoeu, e ntšo, e tala, e thokoa, e tšehla, e khubelu, e putsoa, ea lamunu.
Post Processing
Kaha mehlala e hatisoa ho sebelisoa theknoloji ea MJF, e ka etsoa lehlabathe habonolo, ea penta, ea electroplated kapa skrine e hatisoang.
Lisebelisoa tsa Vacuum Casting
Bakeng sa lisebelisoa tse ngata tsa polasetiki, mona ke mekhoa ea ts'ebetso ea poso e fumanehang
JS Additive e fana ka litšebeletso tse ntle ka ho fetisisa tsa polasetiki le tšepe bakeng sa mefuta e mengata ea thepa
