Thermoforming feem ntau suav nrog ob hom kev ua haujlwm tseem ceeb: lub tshuab nqus tsev thiab lub siab ua haujlwm. Cov txheej txheem no txawv ntawm txoj kev uas lawv siv quab yuam los ua cov khoom siv yas rhuab. Nov yog ib qho piv txwv ntawm txhua tus:

Vacuum forming:

Txheej txheem:Nyob rau hauv lub tshuab nqus tsev tsim, ib daim ntawv rhuab ntawm cov khoom siv thermoplastic yog draped hla lub pwm. Cov huab cua ces khiav tawm ntawm qhov chaw nruab nrab ntawm daim ntawv thiab cov pwm, tsim kom muaj lub tshuab nqus tsev. Lub atmospheric siab yuam cov ntawv yas rhuab kom ua raws li cov qauv ntawm cov pwm.

Daim ntawv thov:Kev tsim lub tshuab nqus tsev feem ntau yog siv los ua cov khoom loj, qhov ntiav nrog qhov yooj yim lossis tsis yooj yim, xws li ntim cov tais, ntim cov thawv ntim, thiab qee hom ntim khoom pov tseg.

Kev Ua Haujlwm Siab:

Txheej txheem:Kev sib sau siab, tseem hu ua qhov zoo siab tsim, suav nrog kev siv cov huab cua zoo rau saum npoo ntawm cov ntawv yas rhuab kom yuam nws tawm tsam pwm. Qhov no ua rau cov duab ntxaws dua thiab txhais tau tias piv rau lub tshuab nqus tsev.

Daim ntawv thov:Kev sib sau siab yog tsim rau tsim cov khoom nrog cov ntsiab lus ntse dua, sib sib zog nqus nqus, thiab cov duab zoo nkauj dua. Nws feem ntau yog siv los tsim cov khoom lag luam xws li cov khoom siv tsheb, cov khoom siv hluav taws xob, thiab cov khoom vaj huam sib luag.

Thaum cov no yog ob hom txheej txheem thermoforming, kev hloov pauv thiab kev sib txuas ntawm cov txheej txheem no kuj tuaj yeem ua haujlwm nyob ntawm qhov tshwj xeeb ntawm cov khoom tsim. Tsis tas li ntawd, muaj qhov sib txawv hu ua ntxaib-daim ntawv sib sau, qhov twg ob daim ntawv yas raug tsim ib txhij thiab fused ua ke los tsim ib qho hollow nrog ob-walled kev tsim kho.
