Plaub yam uas txiav txim siab qhov tseeb ntawm nyias-walled txhaj molded qhov chaw

Daim ntawv thov ntau yam ntawm cov khoom yas tau dhau los ua ntau dua, los ntawm cov khoom siv yooj yim thiab cov khoom siv hauv chav ua noj mus rau cov khoom siv tshuab, cov khoom siv hluav taws xob, thiab lwm yam khoom siv yas. Txawm li cas los xij, rau cov khoom yas uas muaj cov kev xav tau siab xws li cov khoom siv hluav taws xob, cov khoom siv hluav taws xob yuav tsum tau them rau lawv cov kev xav tau precision txij thaum pib ntawm kev tsim pwm hauv kev txhaj tshuaj molding.
Yam dab tsi txiav txim siab qhov tseeb ntawm cov yas txhaj tshuaj molding ua? Peb tuaj yeem txhim kho qhov tseeb ntawm nyias-walled txhaj molded qhov chaw?
1. Pwm kaw siab: Raws li txoj cai, nws yuav tsum siab tshaj qhov siab ntawm cov yas txhaj tshuaj rau hauv pwm, tsis muaj burrs raws li qhov ntsuas.
2. Kev sib raug zoo ntawm kev siab thiab kev ceev yog ib feem zoo ib yam. Lub hom phiaj ntawm kev siv lub siab thiab ceev rau cov pwm yog los xyuas kom meej tias cov ntaub ntawv raw tuaj yeem nkag mus rau hauv pwm tusyees, kom huv si, thiab nyob rau hauv tus nqi tsim nyog los sau tag nrho cov ces kaum. Yog tias qis dhau, nws yuav ua rau luv luv, shrinkage, thiab yog tias nws siab dhau lawm, yuav muaj burrs, oversaturation, nplaum rau pwm, hlawv, yooj yim puas rau pwm, thiab siab sab hauv.
3. Qhov ceev txiav txim siab qhov xwm txheej ntawm cov khoom siv raw hauv cov pwm khiav thiab cov khoom tiav. Yog tias muaj burrs, oversaturation, hlawv, thiab yog tias nws qeeb qeeb, yuav muaj kev txhaj tshuaj luv luv, shrinkage, kev sib txuas tsis zoo, thiab yooj yim tawg.
4. Qhov kub ntawm cov khoom siv raw sib txawv, thiab yog tias qhov kub thiab txias qis dhau, cov nplaum nplaum yuav tsis pob tshab, ua rau cov xim tsis sib xws. Kev ntxhov siab sab hauv ntawm cov khoom tiav yuav nce ntxiv. Yog hais tias qhov kub thiab txias yog siab dhau lawm, nws yuav ua rau cov ntsia hlau puas. Yog tias qhov kub thiab txias dhau lawm, cov khoom yuav muaj burrs, thiab qhov kub sib txawv yuav tshwm sim vim qhov txias, ua rau shrinkage. Cov khoom siv raw yuav decompose, tig daj, discolor, thiab yog nquag tawg. Lub sijhawm txias yuav ntev dua, thiab cov pa roj yuav tsis yooj yim tawm.
