Casting yog qhov pib ntawm aluminium profile npaj txheej txheem. Yuav tsum tau nqa tawm cov khoom xyaw ua ntej, saib hom thiab cov yam ntxwv ntawmaluminium profiles, thiaj li txiav txim siab tus nqi ntawm ntau yam hlau Cheebtsam ntxiv, tsim nyog configuration ntawm ntau yam raw khoom. Qhov thib ob, nws yog melted, thiab cov khoom tiav yog melted nyob rau hauv lub melting rauv. Cov kauj ruam no yuav tsum tau ua raws li cov kev cai. Cov impurities xws li slag thiab roj nyob rau hauv lub yaj yog tshem tawm los ntawm lub essence technology. Tom qab cov kauj ruam saum toj no tiav lawm, casting yog nqa tawm. Cov ntaub ntawv melted yog ua tiav los ntawm kev siv tshuab casting thiab txias los ua ib puag ncig casting rods ntawm ntau yam specifications.
Kneading yog kauj ruam thib ob hauv kev ua aluminium profiles. Kneading ua rau qhov profile dhau los ua cov duab peb xav tau. Ua ntej, raws li cov duab ntawm cov khoom, cov pwm yog tsim. Lub rhuab puag ncig casting pas nrig yog nyem los ntawm pwm los ntawm lub tshuab kneading. Hauv kneading, cua txias quenching tshuab thiab cov txheej txheem kev laus kuj tseem xav tau los ua kom tiav cov kev kho cua sov thiab ntxiv dag zog. Cov txheej txheem pov tseg thermal ntawm cov khoom siv ntxiv nrog cov qauv sib txawv yog txawv.
Qhov thib peb theem ntawm aluminium profile yog xim. Ua ntej, qhov saum npoo yog muab pov tseg ua ntej, thiab qhov saum npoo yog ntxuav los ntawm kev siv tshuaj lom neeg lossis lub cev, thiaj li ua kom muaj qhov zoo thiab tsis muaj qhov tsis zoo ntawm cov oxide zaj duab xis. Nws tuaj yeem ua tau mechanically ua rau hauv daim iav saum npoo lossis matte xeev. Tom qab ntawd anodized, qhov saum npoo ntawm cov ntawv pov tseg ua ntej, nyob rau hauv qee yam kev mob, lub matrix nto ntawm anodized, tiam ntawm ib zaj duab xis txheej. Thaum kawg, lub pore sealing yog siv los kaw lub pore ntawm cov ntxeem tau oxide zaj duab xis tsim tom qab anodic oxidation, thiaj li txhim khu kev ua tau zoo ntawm oxide zaj duab xis. Cov oxide zaj duab xis yog pob tshab, siv nws cov adsorption muaj zog, adsorption thiab tsub zuj zuj ntawm qee cov khoom siv hlau hauv lub qhov membrane, tuaj yeem ua rau aluminium nto ntxiv rau cov nyiaj, tab sis kuj tuaj yeem pom cov xim dub, bronze, kub thiab ntau lwm yam xim.
