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

Thermoforming yog ib qho txheej txheem tsim khoom uas daim ntawv yas raug cua sov rau hauv ib daim duab yooj ywm, uas tom qab ntawd raug puab lossis tsim los ntawm kev siv pwm, thiab tom qab ntawd txiav kom ua tiav qhov kawg lossis khoom. Ob qho tib si kev tsim lub tshuab nqus tsev thiab kev tsim siab yog ntau hom txheej txheem thermoforming. Qhov sib txawv tseem ceeb ntawm kev tsim siab thiab kev tsim lub tshuab nqus tsev yog tus naj npawb ntawm 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 yooj yim - txiv neej lossis zoo (uas yog convex) thiab poj niam lossis tsis zoo, uas yog concave. Rau cov pwm txiv neej, ib daim ntawv yas raug muab tso rau ntawm cov pwm los tsim ib daim duab qhia txog qhov loj me sab hauv ntawm qhov yas. Rau cov pwm poj niam, cov ntawv thermoplastic raug muab tso rau hauv cov pwm kom ua tiav qhov loj me sab nraud ntawm qhov.

Nyob rau hauv lub siab tsim, ib daim ntawv yas kub raug nias ntawm ob lub pwm (yog li ntawd lub npe), es tsis txhob raug rub ncig ib lub pwm los ntawm kev nqus. Kev tsim khoom siab yog qhov zoo tagnrho rau kev tsim cov khoom yas lossis cov khoom uas xav tau kom raug dua ntawm ob sab thiab / lossis xav tau kev kos tob dua (lawv yuav tsum nthuav dav / tob dua rau hauv pwm), xws li cov khoom siv uas xav tau zoo nkauj ntawm sab nraud thiab snap rau hauv qhov chaw lossis haum rau qhov loj me ntawm sab hauv.
