Xov Xwm Txog Lub Tuam Txhab

1. Vim li cas cov khoom txhaj tshuaj pwm thiaj muaj lub kaum sab xis?

Feem ntau, cov khoom txhaj tshuaj pwm yuav tsum tau ua tiav los ntawm cov pwm sib xws. Tom qab cov khoom txhaj tshuaj pwm raug pwm thiab kho, nws raug coj tawm ntawm qhov pwm qhov lossis lub hauv paus, feem ntau hu ua demolding. Vim yog qhov molding shrinkage thiab lwm yam laj thawj, cov khoom yas feem ntau raug qhwv ib ncig ntawm lub hauv paus lossis raug kaw hauv qhov pwm qhov. Tom qab pwm qhib, pwm tsis tuaj yeem raug rho tawm, uas ua rau yooj yim raukev txhaj tshuaj molding cov khoom kom tawm hauv pwm thiab tiv thaiv qhov chaw ntawm cov khoom txhaj tshuaj kom tsis txhob khawb thaum lub sijhawm demolding. Thaum tsim cov pwm txhaj tshuaj, cov nplaim sab hauv thiab sab nraud ntawm cov tshuaj txhaj tiv thaiv

cov kav dej yuav tsum muaj lub kaum sab xis demolding tsim nyog raws li qhov kev taw qhia demolding.

2.Cov yam tseem ceeb uas cuam tshuam rau qhov loj ntawm lub kaum sab xis ntawm cov khoom txhaj tshuaj molded

1) Qhov loj ntawm lub kaum sab xis demolding nyob ntawm qhov ua tau zoo ntawm cov khoom txhaj tshuaj pwm thiab cov duab ntawm cov khoom, piv txwv li, qhov siab lossis qhov tob ntawm cov khoom, phab ntsa tuab thiab qhov chaw ntawm qhov chaw, xws li qhov roughness ntawm qhov chaw, cov kab ua tiav, thiab lwm yam.

2) Yas tawv muaj lub kaum sab xis loj dua li yas mos;

3) Cov duab ntawm cov khoom uas yuav tsum tau txhaj tshuaj pwm yog qhov nyuaj dua, lossis cov khoom yas nrog ntau qhov molding xav tau lub kaum sab xis demolding loj dua;

4) Yog tias qhov siab ntawm cov khoom txhaj tshuaj pwm loj dua thiab qhov tob dua, qhov me dua lub kaum sab xis demoulding raug saws;

5) Lub phab ntsa tuab ntawm cov khoom txhaj tshuaj pwm nce ntxiv, lub zog ntawm lub qhov sab hauv kom nruj lub hauv paus loj dua, thiab lub kaum sab xis yuav tsum loj dua.
