Dab tsi yog vim li cas rau qhov tawg ntawm cov khoom lub taub hau thaum lub sij hawm tsim cov yas pwm?

Nrog rau txoj kev loj hlob sai ntawm kev lag luam yas thiab kev txhim kho txuas ntxiv ntawm lub zog hauv kev dav dav thiab engineering plastics, daim ntawv thov ntau yam ntawm cov khoom yas kuj nthuav dav, thiab kev siv cov khoom siv yas kuj nce ntxiv. Plastic pwm yog ib qho cuab yeej los tsim cov khoom yas. Nws muaj ob peb pawg ntawm cov khoom, txhua tus nrog molding kab noj hniav hauv. Thaum lub sij hawm txhaj tshuaj molding, cov pwm yog clamped mus rau lub tshuab txhaj tshuaj molding, thiab cov yas molten yog txhaj rau hauv pwm kab noj hniav, txias thiab zoo li hauv cov kab noj hniav. Tom qab ntawd, cov pwm sab saud thiab sab qis yog sib cais, thiab cov khoom raug tshem tawm los ntawm cov pwm kab noj hniav los ntawm cov txheej txheem ejection. Tom qab ntawd cov pwm raug kaw rau kev txhaj tshuaj molding tom ntej, thiab tag nrho cov txheej txheem txhaj tshuaj molding yog cyclic.
Lub pwm yas dav dav muaj ob ntu: pwm txav thiab pwm ruaj khov. Cov pwm txav tau nruab rau ntawm cov qauv txav ntawm lub tshuab txhaj tshuaj molding, thiab cov pwm ruaj khov yog nruab rau ntawm cov qauv ruaj khov ntawm lub tshuab txhaj tshuaj molding. Thaum lub sij hawm txhaj tshuaj molding, cov pwm txav tau thiab ruaj khov raug kaw los tsim cov txheej txheem pouring thiab kab noj hniav. Thaum qhib pwm, cov pwm txav tau thiab ruaj khov yog sib cais kom tshem tawm cov khoom yas.
Cov qauv ntawm cov pwm tuaj yeem sib txawv heev vim qhov sib txawv ntawm ntau yam thiab kev ua tau zoo ntawm cov yas, cov duab thiab cov qauv ntawm cov khoom yas, thiab hom kev txhaj tshuaj tshuab, tab sis cov qauv yooj yim zoo ib yam. Cov pwm feem ntau muaj cov txheej txheem pouring, tswj qhov kub thiab txias, tsim qhov chaw, thiab cov khoom siv. Cov txheej txheem pouring thiab tsim qhov chaw yog cov khoom uas tuaj rau hauv kev sib cuag nrog cov yas thiab sib txawv nrog cov yas thiab cov khoom. Lawv yog cov complex thiab sib txawv heev qhov chaw nyob rau hauv yas pwm uas yuav tsum tau ua kom smoothness thiab raug.
