Temperature Control Thaum Txhaj Molding

Lub tog raj kheej kub: Qhov kub uas yuav tsum tau tswj thaum lub sij hawm txhaj tshuaj molding txheej txheem muaj xws li lub tog raj kheej kub, nozzle kub thiab pwm kub. Thawj ob qhov kub thiab txias feem ntau cuam tshuam rau plasticization thiab ntws ntawm plastics, thiab tom kawg kub feem ntau cuam tshuam rau cov dej ntws thiab txias ntawm plastics. Txhua hom yas muaj qhov sib txawv ntawm qhov kub thiab txias, tib hom yas, vim qhov chaw los yog qib sib txawv, nws qhov kub thiab txias decomposition sib txawv, qhov no yog vim qhov nruab nrab molecular hnyav thiab molecular hnyav faib yog txawv, yas nyob rau hauv ntau hom kev txhaj tshuaj tshuab plasticization txheej txheem kuj txawv, yog li kev xaiv ntawm lub tog raj kheej kub tsis zoo ib yam.
Lub nozzle kub: Lub nozzle kub feem ntau yog me ntsis qis dua qhov kub siab tshaj plaws ntawm lub thoob, uas yog los tiv thaiv "salivation tshwm sim" uas yuav tshwm sim nyob rau hauv lub ncaj-los ntawm nozzle. Qhov kub ntawm lub nozzle tsis tuaj yeem qis dhau, txwv tsis pub nws yuav ua rau cov khoom tawg thaum ntxov thiab lub nozzle yuav raug thaiv, lossis qhov kev ua tau zoo ntawm cov khoom yuav raug cuam tshuam vim yog txhaj tshuaj ntawm cov khoom siv thaum ntxov rau hauv pwm. kab noj hniav.
Pwm kub: Pwm kub muaj qhov cuam tshuam zoo rau kev ua haujlwm sab hauv thiab pom zoo ntawm cov khoom. Cov pwm kub nyob ntawm seb cov yas yog crystalline, qhov loj thiab cov qauv ntawm cov khoom, cov kev xav tau ntawm kev ua haujlwm, thiab lwm yam txheej txheem (kua kub, kev txhaj tshuaj ceev thiab txhaj tshuaj siab, pwm pwm, thiab lwm yam).
