Tuag casting pwm tsim yog tsim nyog los yog tsis yuav ncaj qha mus rau cov yas shrinkage tus nqi, vim cov pwm kab noj hniav dimension yog tau los ntawm kev kwv yees ntawm qhov khoom loj ntawm cov khoom thiab qhov ntswg, thiab lub shrinkage yog los ntawm phau ntawv cov khoom siv ntawm cov khoom siv raws li pom zoo los ntawm cov chaw tsim khoom yas ntawm qhov ntau ntawm qhov tseem ceeb, nws tsis tsuas yog nrog lub rooj vag pwm, qhov rooj qhov chaw thiab kev faib khoom, thiab cov khoom siv hlau lead ua ntawm engineering.
Cov txheej txheem ntawm kev txhaj tshuaj yog cov txheej txheem ntawm kev hloov cov yas ntawm cov khoom hauv lub xeev los yog cov khoom ua kua ua kua thiab ua cov khoom ua haujlwm.Xaiv lub suab ntawm cov qoob loo, rov los ntawm cov yaj, cov chaw nruab nrab, teb, hauv thaj av, nyob rau hauv kev sib koom tes ntawm cov thermosetting ntau thermoset lossis thermoplastic, crystalline los yog non-crystalline, enhanced lossis tsis zoo nrog cov qauv polymer txawv xws li morphology thiab rheological zog.
Cov xwm txheej uas cuam tshuam rau saum toj no yuav tsis cuam tshuam rau lub cev thiab cov khoom siv dag zog, qhov loj, cov duab, ua kom zoo thiab qhov muag zoo ntawm cov khoom yas. Nyob rau hauv no txoj kev, qhov sib txuas ntawm tus txheej txheem ntawm tus txheej txheem thiab qhov polymer qhov kev ua tau zoo, qauv ntawv thiab cov khoom yas yuav tsum tau los ntawm cov khoom yas. Nws yog ib qho tseem ceeb ntawm kev txheeb xyuas cov kev sib raug zoo, thiab tsim kev tsim cov tshuaj molding txheej txheem, qhov tsim thiab tsim pwm raws li cov duab, thiab tseem xaiv cov tshuaj txhaj tshuaj molding. yog txawv ntawm kev txhaj tshuaj molding siab thiab kev txhaj tshuaj. Ntshav siab los yog siab ultra-siab txhaj tshuaj thiab kev siab ceev txhaj tshuaj yog siv los txo tus nqi me me.
Txuas ntxiv los mus xav txog cov txheej txheem tsim ntawm cov pwm txhuam, cov ntsiab lus hauv qab no yuav tsum raug xam tau tias yog tsim los ntawm kev tsim cov tshuaj txhaj muaj pwm ntau dua.Ua kom tsis txhob muaj qhov yuam kev hloov; ; Txhawm rau tiv thaiv qhov yuam kev ntawm pwm precision; Khaws lub suab pwm.
