Tsis tshua muaj siab ntiv nplhaib yog ib txoj kev ua kom muaj kab noj hniav ua rau muaj hlau nyob hauv siab los ua tus casting. Vim hais tias siv qis dua, nws hu ua low pressure casting.
Cov cua compressed qhuav yog maj mam ua tswvcuab rau hauv qhov cub tawg. Cov kua hlau yog ua rau cov pa roj paug, thiab cov kab noj hniav tau ntim hauv qab mus nrog cov kua nce thiab cov kab roj rov qab. Cov pwm yog qhib, thiab txhuas hlau txhuas casting yog coj tawm.
Nta
1. Lub siab thiab kev kub ceev thaum lub caij qhwv tawm yuav tsum kho, yog li nws tuaj yeem siv rau ntau hom pwm txawv (xws li hom hlau, hom xuab zeb, thiab lwm yam), muab ntau yam phom ntau thiab castings ntau ntau.
2. Kev siv cov kua dej hauv qab, cov roj ua kua puv npo, tsis muaj txaws qhov muag, kom tsis txhob muaj cov pa roj nyob hauv cov hluav taws xob thiab lub hauv paus, thiab ua kom zoo dua.
3. Aluminium alloy castings yog crystallized hauv siab. Lub castings muaj ib cov qauv siv compact, ib tus qauv qhia meej, ib qhov chaw saum npoo, thiab cov khoom vaj khoom tsev siab, uas yog qhov tshwj xeeb yog qhov tseem ceeb rau txoj kev pov tseg ntawm cov khoom loj nyias.
4. Tshem tawm qhov kev xav tau los noj cov ris tsho, cov nqi siv hlau tau nce mus txog 90 mus rau 98%.
5. Ua haujlwm tsawg, ua haujlwm zoo, khoom siv yooj yim, yooj yim rau kev siv tshuab thiab kev sib koom tes.
