Yuav ua li cas xaiv ntawm thermoforming thiab txhaj tshuaj molding?

Kev tsim cov txheej txheem ntawm ntau txoj kev tsim feem ntau yog siv lub zog los khoov thiab ncab preheated ntawv hlau raws li qhov yuav tsum tau ua. Qhov tseem ceeb tshaj plaws ntawm kev sib sau yog los xyuas kom meej tias cov phab ntsa thickness ntawm cov khoom yog sib xws li qhov ua tau. Cov laj thawj tseem ceeb ntawm cov phab ntsa tsis sib xws yog: ua ntej, qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov ntawv tsim; thiab qhov thib ob, qhov loj ntawm qhov nrawm nrawm, piv txwv li, cov pa roj ntws thaum lub sij hawm rho tawm thiab nce nqi, lossis qhov txav nrawm ntawm pwm, pwm clamping thav duab, thiab ua ntej -stretching plunger. Kev sib sau yog lwm cov txheej txheem tseem ceeb tom qab daim ntawv (daim ntawv) yog rhuab, nrog rau kev tswj cov txheej txheem tseem ceeb xws li kev tsim kub, kev sib sau siab, thiab kev sib sau ceev.

① Kev Kub Kub: Tom qab cov ntaub ntawv, cov txheej txheem, thiab cov cuab yeej raug txiav txim siab, qhov ntsuas kub yog qhov tseem ceeb cuam tshuam rau cov khoom lag luam zoo, cuam tshuam ncaj qha rau qhov tsawg kawg nkaus thickness, thickness tis, thiab qhov me me yuam kev ntawm cov khoom. Nws tseem cuam tshuam rau elongation thiab tensile lub zog ntawm cov khoom, thiab txawm tias qhov sib sau ceev. Yog li ntawd, nws yuav tsum tau ua tib zoo xav.

② Kev Ua Siab Siab: Siab ua rau cov ntawv hlau deform, tab sis cov khoom muaj peev xwm tiv taus deformation; nws elastic modulus txo nrog nce kub. Ntawm qhov kub ntawm qhov tsim, cov khoom tuaj yeem tsuas yog deform thaum qhov kev ntxhov siab tsim los ntawm lub siab nyob rau hauv cov khoom ntau tshaj qhov elastic modulus ntawm cov khoom ntawm qhov kub. Yog hais tias lub siab thov ntawm ib tug tej yam kub tsis txaus los tsim elongation txaus nyob rau hauv cov ntaub ntawv, tsuas yog nce lub molding siab los yog kub yuav cia rau kev vam meej molding. Txij li cov khoom sib txawv muaj qhov sib txawv elastic moduli thiab qhov sib txawv ntawm qhov kub thiab txias, qhov molding siab txawv nyob ntawm seb hom polymer (xws li tus txheeb ze molecular hnyav), daim ntawv thickness, thiab molding kub.

③ Moulding Ceev Lub ntsiab yog vim li cas rau qhov tsis sib xws ntawm phab ntsa thickness nyob rau hauv cov khoom yog: firstly, qhov sib txawv degrees ntawm stretching nyob rau hauv ntau qhov chaw ntawm daim ntawv molded; thiab qhov thib ob, qhov loj ntawm qhov nrawm nrawm, piv txwv li, cov pa roj ntws thaum lub sij hawm rho tawm thiab nce nqi, lossis qhov txav nrawm ntawm pwm, pwm clamping thav duab, thiab ua ntej -stretching plunger. Moulding ceev yog hais txog qhov nrawm nrawm ntawm cov ntaub ntawv. Ua kom lub molding ceev tuaj yeem ua rau lub voj voog molding thiab txhim kho cov khoom tsim tau. Txawm li cas los xij, kev kub siab molding ntau dhau tuaj yeem cuam tshuam cov khoom zoo.

Peb nkag siab tob tob tias cov ntsiab lus txiav txim siab ua tiav lossis tsis ua tiav; Yog li ntawd, peb kho txhua yam khoom nrog kev saib xyuas zoo, sib zog ua kom tiav.
