Dab tsi yog cov khoom siv feem ntau siv hauv lub tshuab nqus tsev?
Vacuum forming yog txheej txheem tsim khoom uas suav nrog cua sov cov ntawv thermoplastic thiab ncab nws hla lub pwm. Cov txheej txheem no tso siab rau ntau qhov kev xaiv ntawm cov khoom siv, vim nws yuav tsum ua kom ruaj khov, hloov tau, thiab muaj peev xwm ua tau raws li qhov xav tau yam tsis poob nws txoj kev ncaj ncees. Hauv tsab xov xwm no, peb yuav tshawb txog cov khoom siv feem ntau siv hauv lub tshuab nqus tsev thiab sib tham txog lawv cov khoom, qhov zoo, thiab kev siv.
Introduction to Vacuum Forming
Lub tshuab nqus tsev tsim, tseem hu ua thermoforming lossis vacuforming, yog cov txheej txheem nrov siv hauv ntau yam lag luam xws li tsheb, ntim, aerospace, thiab txawm nyob rau hauv kev tsim khoom txhua hnub xws li tais, ntim, thiab khob pov tseg. Nws yog tus nqi-zoo thiab cov txheej txheem ua haujlwm tau zoo uas tso cai rau cov tuam txhab tsim cov duab nyuaj nrog cov txheeb ze yooj yim.
Lub tshuab nqus tsev txheej txheem pib nrog ib daim ntawv tiaj tus ntawm cov khoom siv thermoplastic, uas yog clamped rau hauv ib lub thav duab. Daim ntawv yog ces rhuab kom txog thaum nws ua pliable, thaum lub sij hawm nws yog stretched tshaj ib tug pwm siv lub tshuab nqus tsev vacuum. Lub tshuab nqus tsev tshem tawm cov huab cua ntawm daim ntawv thiab cov pwm, thawb cov khoom nruj nreem tiv thaiv pwm nto, yog li muab nws cov duab kawg. Thaum cov khoom txias thiab solidifies, cov pwm raug tshem tawm, tawm hauv qab cov khoom tsim.
Cov khoom siv hauv tshuab nqus tsev
Ntau cov ntaub ntawv feem ntau yog siv los ua lub tshuab nqus tsev. Qhov kev xaiv ntawm cov khoom yog nyob ntawm seb yam xws li daim ntawv thov, tus nqi, muaj, thiab cov kev cai tshwj xeeb ntawm cov khoom. Cia peb tshawb txog qee yam ntawm cov khoom siv feem ntau siv hauv lub tshuab nqus tsev.
