Cov txheej txheem ntawm casting

Casting yog txheej txheem tsim khoom uas muaj cov kua lossis cov khoom molten xws li hlau, yas, lossis ceramic yog nchuav rau hauv pwm los tsim ib qho khoom ntawm cov duab thiab loj. Ntawm no yog ib tug step-by-step txheej txheem ntawm casting:

1. Tsim: Thawj kauj ruam hauv casting yog tsim los yog tau txais kev tsim lossis qauv ntawm qhov yuav tsum tau cam khwb cia. Qhov no tuaj yeem ua los ntawm CAD software lossis los ntawm tes.

2. Pwm ua: Ib qho pwm yog tsim los tuav cov khoom ua kua thaum lub sij hawm casting txheej txheem. Cov pwm tuaj yeem tsim los ntawm ntau yam ntaub ntawv xws li xuab zeb, plaster, lossis hlau, nyob ntawm seb cov khoom raug cam khwb cia. Cov pwm yuav tsum tau tsim los tso cai kom yooj yim tshem tawm ntawm qhov ua tiav.

3. Melting: Cov khoom ua kua yog yaj hauv lub cub tawg lossis lwm yam khoom siv cua sov. Qhov kub yuav tsum siab txaus kom yaj cov khoom tab sis tsis siab heev uas ua rau puas pwm.

4. Pouring: Cov khoom ua kua yog nchuav rau hauv pwm thaum tseem kub. Cov pwm feem ntau yog preheated los tiv thaiv qhov kub thiab txias uas tuaj yeem ua rau muaj qhov tsis zoo hauv cov khoom tiav.

5. Txias: Cov khoom tso cai kom txias thiab khov rau hauv pwm. Nyob ntawm cov khoom thiab qhov loj ntawm cov pwm, cov txheej txheem no tuaj yeem siv sijhawm ntau teev lossis hnub.

6. Kev tshem tawm: Thaum cov khoom tau txias thiab tawv, cov pwm raug tshem tawm, thiab cov khoom tiav raug tso tawm. Feem ntau, ntxiv tom qab ua tiav, xws li kev sib tsoo lossis polishing, yuav tsum ua kom tiav qhov xav tau ntawm qhov chaw tiav.

7. Kev tshuaj xyuas: Cov khoom tiav yog kuaj xyuas qhov zoo thiab qhov tsis zoo. Yog tias pom muaj qhov tsis xws luag, qhov yuav tsum tau rov ua dua lossis muab pov tseg.

Casting yog txheej txheem ntau yam uas tuaj yeem siv los tsim ntau qhov chaw, los ntawm me me thiab yooj yim mus rau loj thiab complex. Cov txheej txheem kuj tseem siv tau los tsim ntau qhov chaw zoo ib yam, ua kom muaj txiaj ntsig zoo thiab raug nqi tsim khoom.
