1. Aluminium alloy lub ntiajteb txawj nqus casting casting qauv yog dav siv vim nws zoo ntawm high yield yield, ntxuav chaw ua hauj lwm, kev ruaj ntseg lag luam, du casting deg thiab meej sab qauv.
2. Cov txheej txheem ntawm aluminium alloy gravity casting muaj ib tug heev nruj kev sib raug zoo nrog cov qauv ntawm cov qauv puab. Aluminium alloy gravity casting tsis tsuas yog ua kom cov dej txhuas tuaj yeem nkag rau cov pwm yas yam ntseeg tab sis kuj excludes tus nkag ntawm khib nyiab, tshem cov kab noj hniav hauv txoj kev ua tus casting. Cov huab cua, kom lub sij hawm sau ntawm castings, tuaj yeem ua rau qhov kub thiab txias ntawm lub castings thiab castings tusyees, thiab xyuas kom meej tias qhov kev txiav txim siab sib zog ntawm cov castings.
3. Aluminium alloy gravity casting casting txoj hauj lwm thaum lub sij hawm casting:
a. Lub ntsiab ntawm cov casting nyob rau hauv qis ib feem thiab tus nplaum ntu kuj nyob hauv qis dua.
b. Lub cheeb tsam casting yog loj downwards, tsis txhob tawm qhov qhov.
c. los xyuas kom meej qhov casting casting temperature.
d. Xaiv cov tub ntxhais uas tsim nyog rau kev kos.
e. Casting lub thawv. Qhov chaw ntawm casting yog tib yam li qhov chaw ntawm casting txias.
