Li-castings tsa Lehlabathe la Resin tse koahetsoeng esale pele bakeng sa Likoloi
Lintho tse bonahalang
Lisebelisoa tse tloaelehileng tse sebelisoang ho li-castings tse koahetsoeng esale pele indastering ea likoloi ke:
• Aine e Bohlooho: E fana ka castability e ntle, machinability, 'me e sebelisoa likarolong tse fapaneng tsa enjene hammoho le likarolo tsa sebopeho.
• Aene ea Ductile: E thata e nang le matla a phahameng, e sebelisoang likarolong tse sa ameng feela ka tlhaho empa hape li thata.
• Lisebelisoa tsa Aluminium: E bobebe ka boima ba 'mele ebile e hanela mafome, aluminium e sebelisoa libolokong tsa enjine le matlong a phetiso.
• Lisebelisoa tsa tšepe: E sebelisoa ka mokhoa o tsitsitseng o phahameng le oa tlhokahalo ea matla a phahameng, ke hore, likarolo tsa sebopeho hammoho le karolo ea bohlokoa ea polokeho.
Litlhaloso
• Boima ba 'mele: Likarolo tse nyane, tsa metsotso e nang le ligrama tse 'maloa ka boima ba' mele ho li-bulky, likarolo tse kholo tse nang le lik'hilograma tse makholo a seng makae.
• Mamello: Li-castings li entsoe ka mamello e phahameng, hangata lipakeng tsa ± 0.5mm molemong oa ho fihlela litlhoko tse nepahetseng tsa liindasteri tsa likoloi.
• Surface Finish: Li-resin tsa pre-coat li etsa hore ho be le sepakapaka se setle se sieang sebaka se senyenyane bakeng sa machining a post-cast.
• Matla a Mechini: Li-castings li entsoe ka ho khetheha ho fihlela litlhoko tse thata tsa likoloi, tse mamellang mocheso o phahameng, khatello e phahameng, hammoho le ho phunya ho tsoelang pele.
Mekhoa ea Tlhahiso
1. Pōpo ea Paterone: Sebopeho se nepahetseng se bōptjoa ho tloha sebopeho sa karolo e reriloeng. Hangata mohlala o entsoe ka tšepe kapa resin e le hore o tla tsitsa ka mokhoa oa ho lahla.
2. Ho roala: Mohlala o koahetsoe ka lehlabathe le fatše le resin. Sehlahisoa sena se thatafalitsoe ke resin, e leng se etsang hore ho be le hlobo e thata e khonang ho mamella mocheso oa tšepe e qhibilihisitsoeng.
3. Ho Bopa: Mokhoa ona o pota-potiloe ka lehlabathe le koahetsoeng ka resin e le ho etsa hlobo e tiileng.
4. Ho phekola: Hlobo e phekoloa ka mokhoa o e thatafatsang, ho e lokisetsa bakeng sa mocheso o phahameng oa tšepe e qhibilihisitsoeng.
5. Tšebeliso ea tšepe: Tšepe e qhibilihisitsoeng e tšeloa ka har'a hlobo, e tlatsang sekoti ebe e nka sebopeho ho latela mohlala.
6. Ho pholisa le ho sa Bopeha: Tšepe e lumelloa ho pholile pele e senya hlobo.
7. Qetella: Sebapali sea hloekisoa, se tlosoa, 'me se etsoa ka mochine ka mokhoa o nepahetseng e le ho finyella litlhoko tse boletsoeng.
Tlhahlobo ea Boleng le Tlhahlobo
• Tlhahlobo ea Pono: E etsa bonnete ba hore ha ho na likoli tse kang crack kapa void tse teng ho casting.
• Tlhahlobo ea Boemo: The casting e lekanyetsoa ka lisebelisoa tse nepahetseng ho ba litekanyo tse se nang sekoli.
• Teko ea Mechini: E kenyelletsa ho thatafala, ho tsitsipana, le liteko tsa tšusumetso ho netefatsa hore mochini o ka mamella khatello ea ts'ebetso ea koloi.
• Teko e sa Senyeheng (NDT): Ultrasonics kapa X-rays li sebelisoa ho lemoha mefokolo ea ka hare e le mohato o lebisang ho boleng ba boleng.
Likarolo tsa Bohlokoa
• Matlafatso e Matlafalitsoeng: Li-pre-coat castings tse tsoang lehlabatheng la resin li entsoe ka litlhoko tse phahameng tsa ts'ebetso ea lienjineri tsa likoloi joalo ka ha ho nahanoa ka likarolo.
• Boleng bo Phahameng ka ho Fetisisa: Sephetho sa boleng ba boleng bo phahameng ho tloha ho roala ka resin se theola boemo ba litlhoko tsa bobeli tsa machining.
• Nepahetseng e Phahameng: E fana ka mamello e fokolang hammoho le moralo oa ka tlung bakeng sa karolo ea likoloi tsa maemo a holimo.
• Corrosion Resistance: Lintho tse ling tsa alloying, ke hore, aluminium le tšepe e sa hloekang, li na le khanyetso e phahameng mabapi le ho bola, e lelefatsang bophelo ba karolo.
• Likhetho tse bobebe: Alloy e bobebe e boloka boima ba koloi bo le teng, e ntlafatsa moruo oa mafura ntle le ho tela boima.
Lisebelisoa tsa indasteri
Lits'oants'o tsa lehlabathe tsa resin tse koahetsoeng esale pele li sebelisoa haholo makaleng a fapaneng a likoloi, ho kenyelletsa:
• Likarolo tsa Enjine: Lihlooho tsa li-cylinder, mefuta e mengata ea ho noa, le lipane tsa oli.
• Likarolo tsa Phetiso: Shafting, li-gearbox le matlo.
• Suspension and Chassis: Joalo ka matsoho a emisitsoeng le masakaneng a emisitsoeng.
• Litsamaiso tsa Braking: Likarolo tsa likarolo tsa braking ke hore li-rotor tsa brake, brake calipers.
• Exhaust Systems: ke hore, turbocharger le exhaust manifolds.
Ho paka le ho Boloka
Ntho e 'ngoe le e' ngoe ea ho lahla e tletse ka hloko e kholo hore e se ke ea senyeha ha e tsamaea. Li boetse li behiloe ka kamoreng e nang le maemo hore li se ke tsa kopana ka kotloloho le likarolo tsa tikoloho tse ka amang boleng ba eona.
Thomello
Hang ha li-castings li fetile litlhahlobo tsohle, li pakiloe ka mokhoa o sireletsehileng 'me li romelloa lefatšeng ka bophara. Thomello e kenyelletsa litokomane tsohle tse hlokahalang, ho kenyeletsoa litifikeiti tsa boleng le litlaleho tsa tlhahlobo, ho netefatsa hore ho latela maemo a indasteri.
