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

Feem ntau, txhaj tshuaj molded cov khoom yuav tsum tau ua tiav los ntawm cov pwm sib thooj.Tom qab kev txhaj tshuaj molded khoom yog molded thiab kho, nws raug tshem tawm ntawm pwm kab noj hniav los yog core, feem ntau hu ua demolding.Vim yog molding shrinkage thiab lwm yam yog vim li cas, cov khoom yas feem ntau qhwv ib ncig ntawm lub hauv paus los yog daig rau hauv cov pwm kab noj hniav.Tom qab cov pwm qhib, cov pwm tsis tuaj yeem raug tshem tawm, uas pab txhawb rautxhaj tshuaj molding cov khoom tawm ntawm cov pwm thiab tiv thaiv qhov chaw ntawm cov khoom txhaj tshuaj molded los ntawm khawb thaum lub sij hawm demolding.Thaum tsim ib qho kev txhaj tshuaj pwm, sab hauv thiab sab nrauv ntawm qhov txhaj tshuaj pro

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

2.Cov yam ntxwv cuam tshuam qhov loj ntawm lub demolding lub kaum sab xis ntawm txhaj tshuaj molded khoom

1) Qhov loj ntawm lub demolding lub kaum sab xis nyob ntawm qhov kev ua tau zoo ntawm cov khoom txhaj tshuaj molded thiab cov geometry ntawm cov khoom, piv txwv li, qhov siab lossis qhov tob ntawm cov khoom, phab ntsa thickness thiab kab noj hniav ntawm lub xeev, xws li deg roughness, ua kab, thiab lwm yam.

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

3) Cov duab ntawm cov khoom yuav tsum tau txhaj tshuaj molded yog qhov nyuaj, los yog cov yas nrog ntau molding qhov xav tau ib tug loj demolding lub kaum sab xis;

4) Yog tias qhov siab ntawm kev txhaj tshuaj molded cov khoom loj dua thiab lub qhov tob dua, qhov me dua lub demoulding lub kaum sab xis tau txais yuav;

5) Lub phab ntsa tuab ntawm cov khoom txhaj tshuaj molded yog nce, lub zog ntawm lub puab lub qhov kom nruj rau cov tub ntxhais yog ntau dua, thiab lub kaum sab xis yuav tsum loj dua.
