Kev txhaj tshuaj molding yog dab tsi?
Kev txhaj tshuaj molding yog txheej txheem tsim khoom uas koom nrog kev txhaj tshuaj thermoplastic lossis thermosetting plastics nyob rau hauv qhov siab siab rau hauv cov pwm kab noj hniav, qhov chaw uas lawv txias thiab khov kho kom tsim tau cov khoom ntawm cov duab tshwj xeeb.
Los ntawm kev tswj qhov kub thiab txias thiab kev tswj xyuas qhov siab, cov yas ntws ntws yog molded rau hauv cov duab geometric complex uas yuav tsum tau los ntawm tus tsim nyob rau hauv ib lub sij hawm luv luv.
Granular raw cov ntaub ntawv yog pub rau hauv lub hopper, thiab los ntawm kev sib hloov shearing ntawm cov ntsia hlau thiab maj mam cua sov ntawm cov cua kub chim, cov khoom undergoes ib tug transformation ntawm ib tug glassy lub xeev mus rau lub viscous flow xeev. Tom qab ntawd, nyob rau hauv lub thrust ntawm kev txhaj tshuaj mechanism, cov yaj nyob rau txhua lub ces kaum ntawm cov pwm, thiab tom qab ntawd, los ntawm ib tug precisely tswj qhov system txias, cov khoom tiav crystallization thiab solidification nyob rau hauv ib lub sij hawm luv luv.
Kev txhaj tshuaj molding tsis tsuas yog muaj cov yam ntxwv ua tau zoo ntawm "ib- kauj ruam molding," ua rau cov khoom loj ntawm cov qauv tsim tau, tab sis nws kuj tau siv dav hauv ntau yam kev lag luam xws li tsheb, khoom siv hluav taws xob, khoom siv kho mob, qhov chaw teeb pom kev zoo, thiab cov khoom siv tshuab.
