Kev txhaj tshuaj molding yog ib qho tseem ceeb ntawm cov txheej txheem tsim khoom uas tsim ntau lab ntawm cov khoom uas peb siv hauv peb lub neej txhua hnub. Cov txheej txheem yuav tsum tau yaj cov yas pellets thiab txhaj rau hauv pwm los ua cov khoom tiav. Cov yas txhaj tshuaj molding tsis ua lub luag haujlwm tseem ceeb hauv qhov zoo ntawm cov khoom kawg. Nov yog qee qhov tseem ceeb ntawm cov txheej txheem uas txiav txim siab qhov ua tiav ntawm cov txheej txheem:
1. Kev txhaj tshuaj siab: Lub siab siv rau cov yas molten los sau cov pwm yog qhov tseem ceeb uas cuam tshuam rau cov khoom zoo. Lub siab yuav tsum yog qhov tseeb thiab zoo ib yam thoob plaws hauv cov txheej txheem txhaj tshuaj kom ntseeg tau tias homogeneity thiab conformity ntawm cov khoom kawg.
2. Kev txhaj tshuaj ceev: Qhov kev txhaj tshuaj ceev txiav txim siab sai npaum li cas cov khoom txhaj tshuaj rau hauv pwm. Qhov ceev yuav tsum tau ua kom zoo dua kom ntseeg tau tias cov pwm puv sib npaug thiab cov khoom tsis puas.
3. chim kub: Qhov kub ntawm cov yas yaj yuav tsum yog qhov tseeb kom cov khoom ntws tau yooj yim thiab sib npaug rau hauv pwm. Qhov kub thiab txias yuav tsum tau khaws cia thoob plaws hauv cov txheej txheem, thiab txhua qhov kev hloov pauv tuaj yeem ua rau muaj qhov tsis xws luag thiab tsis sib xws hauv cov khoom tiav.
4. Lub sijhawm txias: Lub sijhawm txias ntawm cov khoom molded yog qhov tseem ceeb hauv kev txiav txim siab qhov kawg. Lub sij hawm txias yuav tsum yog qhov tseeb kom ntseeg tau tias cov khoom tsis ntsws los yog deform.
5. Pwm tsim: Cov pwm tsim ua lub luag haujlwm tseem ceeb hauv qhov zoo ntawm cov khoom kawg. Lub pwm tsim tau zoo ua kom cov khoom tsim tau raug thiab tsis tu ncua.
Hauv kev xaus, yas txhaj tshuaj molding yog txheej txheem meej uas yuav tsum tau ua tib zoo xav txog qhov tsis zoo uas cuam tshuam rau cov khoom zoo. Nws yog ib qho tseem ceeb uas yuav tau ua hauj lwm nrog cov kws tshaj lij uas paub txog qhov tseem ceeb ntawm cov kev txwv no los tsim cov khoom zoo. Nrog rau qhov tsis zoo thiab kev txawj ntse, yas txhaj tshuaj molding tuaj yeem tsim cov khoom lag luam zoo thiab muaj txiaj ntsig zoo.
