Dab tsi yog qhov txawv ntawm Lub Tshuab Nqus Tsev, Thermoforming, thiab Pressure Forming?

Thermoforming yog cov txheej txheem tsim khoom uas ib daim ntawv ntawm cov yas yog rhuab mus rau hauv cov duab hloov tau yooj yim, uas yog tom qab ntawd zoo li tus los yog tsim los ntawm cov pwm, thiab ces txiav mus rau qhov kawg los yog cov khoom. Ob qho tib si lub tshuab nqus tsev thiab lub siab sib sau yog ntau hom thermoforming txheej txheem. Qhov sib txawv tseem ceeb ntawm kev tsim lub siab thiab lub tshuab nqus tsev yog cov pwm uas siv.

Lub tshuab nqus tsev tsim yog hom yas thermoforming uas yooj yim tshaj plaws thiab siv cov pwm thiab lub tshuab nqus tsev siab kom ua tiav qhov xav tau geometry. Nws yog qhov zoo tagnrho rau qhov chaw uas tsuas yog yuav tsum tau ua kom zoo ib yam ntawm ib sab, xws li contoured ntim rau zaub mov lossis khoom siv hluav taws xob.

Muaj ob hom pwm - txiv neej los yog zoo (uas yog convex) thiab poj niam los yog tsis zoo, uas yog concave. Rau cov txiv neej pwm, ib daim ntawv yas yog muab tso rau ntawm cov pwm los ua ib qho kev nthuav dav ntawm qhov ntev ntawm cov yas. Rau cov poj niam pwm, cov nplooj ntawv thermoplastic tau muab tso rau hauv cov pwm kom meej meej rau sab nrauv ntawm qhov.

Nyob rau hauv lub siab tsim , ib daim ntawv yas rhuab yog nias ntawm ob lub pwm (li no lub npe), tsis yog rub ib ncig ntawm ib qho pwm los ntawm kev nqus. Kev ua kom siab yog qhov zoo tshaj plaws rau kev tsim cov khoom yas lossis cov khoom uas yuav tsum tau ua kom zoo nkauj ntawm ob sab thiab / los yog xav tau kev sib sib zog nqus (lawv yuav tsum tau txuas ntxiv mus / tob rau hauv pwm), xws li cov khoom siv uas yuav tsum tau saib zoo nkauj. nyob rau sab nrauv thiab snap rau hauv qhov chaw lossis haum rau qhov loj me ntawm sab hauv sab hauv.
