Phab ntsa thickness ntawmyas qhov chawmuaj kev cuam tshuam zoo rau qhov zoo. Thaum cov phab ntsa thickness me me dhau lawm, qhov kev khiav hauj lwm siab yog siab, thiab nws yog ib qho nyuaj rau cov yas loj thiab cov khoom siv los sau cov kab noj hniav. Qhov ntev ntawm phab ntsa thickness ntawm cov khoom yas yuav tsum ua tau raws li cov hauv qab no:
1. Muaj lub zog txaus thiab rigidity;
2. tuaj yeem tiv taus qhov cuam tshuam thiab kev co ntawm lub tshuab demolding thaum demoulding;
3. tuaj yeem tiv taus lub zog nruj thaum sib dhos.
Yog hais tias cov phab ntsa thickness tsis zoo xav nyob rau hauv lub tsim theem ntawm kev txhaj tshuaj molded qhov chaw, yuav muaj teeb meem loj tom qab ntawm cov khoom.
Kab lus no tsom mus rau kev tsim khoom ntawm cov thermoplastic txhaj molded qhov chaw, xav txog cov nyhuv ntawm cov phab ntsa thickness ntawm lub sij hawm voj voog, cov khoom shrinkage thiab warpage, thiab nto zoo.
Nce phab ntsa thickness ua rau kom lub sij hawm voj voog
Txhaj molded yas qhov chaw yuav tsum tau txias txaus ua ntej yuav ejection ntawm pwm kom tsis txhob deformation ntawm cov khoom vim ejection. Thicker qhov chaw ntawm cov khoom yas yuav tsum tau txias lub sij hawm ntev dua vim qhov qis dua cov cua sov hloov, yuav tsum tau siv sij hawm ntxiv.
Nyob rau hauv txoj kev xav, lub sij hawm txias ntawm ib qho kev txhaj tshuaj molded yog proportional rau lub square ntawm phab ntsa thickness ntawm lub thickness ntawm ib feem. Yog li ntawd, cov phab ntsa tuab tuab yuav txuas ntxiv lub voj voog txhaj tshuaj, txo cov naj npawb ntawm cov khoom tsim tawm ib lub sijhawm, thiab nce tus nqi ib feem.
Thicker seem muaj ntau dua rau warping
Thaum lub sij hawm txhaj tshuaj molding txheej txheem, nrog rau qhov txias, lub shrinkage ntawm txhaj molded qhov chaw yuav inevitably tshwm sim. Tus nqi ntawm shrinkage ntawm cov khoom yog ncaj qha ntsig txog phab ntsa thickness ntawm cov khoom. Uas yog hais, qhov twg phab ntsa thickness yog thicker, lub shrinkage yuav ntau dua; qhov twg phab ntsa thickness yog thinner, lub shrinkage yuav me me. Lub warpage ntawm kev txhaj tshuaj molded qhov chaw feem ntau tshwm sim los ntawm qhov sib txawv ntawm qhov shrinkage ntawm ob qhov chaw.
Nyias, cov khoom sib xws txhim kho qhov zoo
Kev sib xyaw ua ke ntawm cov ntu nyias thiab tuab yog qhov ua rau muaj kev sib tw sib tw vim tias cov yaj ntws nrawm dua ntawm ntu tuab. Cov nyhuv sib tw tuaj yeem tsim cov hnab tshos huab cua thiab cov kab txuas ntawm qhov chaw, ua rau cov khoom tsis zoo. Tsis tas li ntawd, cov khoom tuab kuj tseem ua rau dents thiab voids yam tsis muaj sijhawm txaus nyob thiab siab.
Txo qhov thickness
Txhawm rau ua kom lub sijhawm luv luv, txhim kho qhov kev ruaj ntseg, thiab tshem tawm qhov tsis xws luag, txoj cai yooj yim ntawm tus ntiv tes xoo rau ib feem thickness tsim yog kom lub thickness ntawm nyias nyias thiab zoo li ua tau. Kev siv cov stiffeners yog ib txoj hauv kev zoo kom ua tiav qhov yuav tsum tau muaj zog thiab lub zog thaum tsis txhob muaj cov khoom tuab heev.
Ntxiv rau qhov no, qhov ntev ntawm ib feem yuav tsum coj mus rau hauv tus account cov khoom siv ntawm cov yas siv, hom kev thauj khoom thiab kev ua haujlwm ntawm qhov yuav raug; thiab cov kev cai sib dhos zaum kawg yuav tsum tau txiav txim siab.
Cov saum toj no yog qee qhov sib koom ntawm phab ntsa tuab ntawm kev txhaj tshuaj molded qhov chaw.
