Cov yam ntxwv thiab daim ntawv thov Scope ntawm yas pwm ua

Vim yog cov kev txwv ntawm cov pwm yas, qhov kaw ntawm pwm yog ceev, uas ua rau cov khoom siv ntau dhau. Txawm li cas los xij, siv cov pwm zoo li no los txwv qhov ceev thiab lub zog ntawm cov khoom yas tsis siab, thiab cov ntaub ntawv ntau dua yog nkim. Tab sis yog tias nws tau npaj ua cov pwm yas qhib, nws tsis tsuas yog muaj cov qauv yooj yim, siv tau zoo, thiab tus nqi qis.
Yog tias qhib cov pwm yas siv los txwv, tsis yog tsuas yog cov khoom yooj yim tshem tawm xwb, tab sis kuj tseem txwv rau qhov chaw tiaj tus, qhov chaw ntawm lub koom haum thawb raug tshem tawm, ua rau cov pwm pwm yooj yim dua thiab tag nrho cov txheej txheem kev txwv yooj yim dua thiab ua tau.
Cov pwm yas kuj tseem siv tau rau cov yas uas muaj cov ntim tshwj xeeb, siab tshwj xeeb, thiab tshwj xeeb tshaj yog cov dej fluidity. Thaum lub sij hawm txhaj tshuaj molding, lub hardening thiab shaping kub ntawm cov khoom yog siab, thiab ib tug kuj uniform degree ntawm hardening yuav tau txais nyob rau hauv lub rooj khoom. Tsis tas li ntawd, cov thermal rigidity ntawm cov khoom kuj tseem siab, uas tuaj yeem siv los tsim cov khoom siv phab ntsa tuab uas nyuaj rau xaiv rau compression molding.
