Tus txheej txheem tseem ceeb ntawm kev tuag castting yog kom sai tau txhaj kua rau hauv cov pob zeb ntawm cov hlau loj, thiab tom qab ntawd txias thiab khov kho nws kom muaj lub zog. Cov txheej txheem tuag casting tsuas yog suav nrog cov kauj ruam hauv qab no:
Pwm npaj: ua ntej, preheat mould kom paub tseeb tias cov pwm ua kom muaj kev ua haujlwm sai sai ntawm cov hlau ua haujlwm sai sai, uas cuam tshuam rau qhov zoo ntawm cov casting. Nyob rau tib lub sijhawm, cov roj nqus hniav ntub dej ntawm cov pwm kom txo qis kev sib txhuam ntawm cov hlau thiab cov hlau molten, uas yooj yim rau kev ua kom pom kev.
Hlau SMELTING: Raws li kev xav tau kev ua tau zoo, xaiv cov khoom siv hlau uas yuav tsum tau, thiab lwm yam), thiab ua kom sov thiab ua kom sov thiab ua kom sov. Nruj me ntsis tswj lub smelting kub kom ntseeg tau tias cov hlau molten muaj cov tshuaj zoo.
Kev ntsuam xyuas hluav taws xob siab: lub smelted molten hlau tau sai sai rau hauv cov pwm kab noj hniav nyob rau hauv kev txhaj tshuaj ntawm lub tshuab tuag casting lub cev. Kev kub siab tuaj yeem ua rau cov hlau molten kom sai tau sau txhua lub ces kaum ntawm cov pwm, kom pom qhov tseeb ntawm qhov tseeb thiab qhov chaw zoo ntawm cov casting.
Siab tuav thiab txias: Tom qab cov molten hlau ua rau cov kab noj hniav, ib qho siab yog tswj kom ntseeg tau tias cov txheej txheem sib xws thiab txo qhov tsis xws luag xws li shrinkage thiab shrinkage. Sij hawm dhau mus, Molten cov hlau maj txias txias thiab solidifies hauv pwm, tsim cov duab ua ntu zus nrog cov pwm kab noj hniav. Txhim kho: Thaum lub Casting yog ua tiav, lub casting yog thawb tawm ntawm cov pwm los ntawm lub ejector ntawm cov tuag-casting tshuab compting. Tom qab ntawd, qhov ntau dhau xws li lub rooj vag, khiav, thiab nyem rau ntawm lub casting raug tshem tawm.
