Apple MacBook Housings: Ultra-thin aluminium tuag casting ua ke nrog CNC xov ua kom lub zog thiab lub teeb yuag.
Kev daws teeb meem
Nqus tuag casting thiab siab -frequency vibration filling txo porosity.
Txoj kev loj hlob ntawm Al-Mg alloys nrog ntau dua ductility txhim kho kev tawg tsis kam.
2. Loj-Scale Tuag Casting: Tsav kev sib xyaw ua ke
Kev Sib Tw
Tshuab Peev Xwm: Cov txheej txheem loj loj yuav tsum tau nias nrog lub zog clamping ntawm 6,000-9,000 tons lossis ntau dua, feem ntau muab los ntawm IDRA (Ltalis) thiab LK Group (Tuam Tshoj).
Residual Stress thiab Warpage: Cov cua txias tsis sib xws tuaj yeem ua rau muaj kev cuam tshuam loj, cuam tshuam rau kev sib txuas hauv qab thiab kev sib koom ua ke.
Kev lag luam Case
Tesla Model Y Tsheb Hauv Qab Hauv Qab Casting: Ua los ntawm IDRA's 9,000-tuj Giga Xovxwm, hloov ntau dua 70 qhov chaw thiab txo qis dua 300 cov ntsiab lus vuam, nrog qhov hnyav ntawm ~ 10%.
XPeng G6 Integrated Subframe: Ua nrog Suav LK cov cuab yeej, ua kom loj - nplai lub cev kev koom ua ke.
Kev daws teeb meem
Muab faib cov cua txias raws nrog - sijhawm saib xyuas kom txo qis kev ntxhov siab.
Thaum ntxov -theem CAE simulations rau deformation kwv yees thiab tsim optimization.
3. Ntau-Cavity Moulds: Kev Sib Tw hauv Siab-Volume Production
Kev Sib Tw
Gating Balance: Ntau-kab kab noj hniav pwm yuav tsum xyuas kom meej ib txhij sau thoob cov kab noj hniav. Tsis tas li ntawd, qhov sib txawv ntawm qhov sib txawv thiab qhov tsis zoo tshwm sim.
Pwm Lub Neej: Ntau dua thermal loads ua kom tawg thiab hnav, nce nqi kho.
Kev lag luam Case
Bosch Sensor Housings: 8-kab kab noj hniav pwm nrog txhua xyoo tsim nyob rau hauv ntau lab, vam khom rau precision gating tsim thiab lub tshuab nqus tsev pab.
Denso Automotive Cov Me Me: Cov pwm txuas ntxiv lub neej dhau los ntawm nitriding thiab PVD-coated tool steels, txo qis sijhawm thiab nqi.
Kev daws teeb meem
Digital simulation kom optimize qhov sib npaug ntawm qhov rooj.
Kev siv cov cuab yeej siv siab tshaj plaws (kho H13) thiab 3D- luam tawm pwm ntxig los txhim kho cov kav ntev.
4. Txoj Kev Nyuaj Siab thiab Kev Qhia Txog Yav Tom Ntej
Kev simulation-Tsav Tsim
OEMs vam khom rau software xws li MAGMA thiab ProCAST los kwv yees sau, cua sov ntws, thiab kev ntxhov siab seem.
Ntse Casting Cells
Hauv Suav teb, qee qhov chaw tsim khoom siv "casting Islands," sib koom ua ke cov xovxwm, cov neeg hlau, pwm kub chav tsev, thiab cov tshuab tshuaj xyuas rau lub sijhawm tiag tiag - xyuas cov txheej txheem sijhawm.
Tshiab Alloy Development
High-ductility Al-Mg-RE alloys thiab tshav kub-resistant aluminium alloys tau tshwm sim rau kev nyab xeeb-tseem ceeb thiab siab- daim ntawv thov kub.
Sustainability thiab Circular Economy
Lub EU xav kom 30% rov ua dua txhuas hauv tsheb los ntawm 2030, ua kom lub zog ntsuab tuag casting pib.
Xaus
Nyias-phab ntsa, loj- nplai, thiab ntau- kab noj hniav tuag casting sawv cev peb lub ntsiab lus qhia rau kev sib sib zog nqus thiab kev ua haujlwm hauv kev tsim khoom siab heev. Thaum cov txheej txheem no ua rau muaj kev tsim kho tshiab hauv NEVs thiab hluav taws xob, lawv kuj nce bar rau cov txheej txheem, khoom siv, thiab khoom siv. Nyob rau hauv lub neej yav tom ntej, cov neeg uas ua nyob rau hauv ntse manufacturing, alloy innovation, thiab sustainable ntau lawm yuav coj cov kev sib tw nyob rau hauv complex tuag casting.
