Tsom xam seb yog vim li cas rau cov xim tsis sib xws ntawm kev txhaj tshuaj molding cov khoom tseem ceeb rau cov xim tsis ncaj ntawm kev txhaj tshuaj molding khoom thiab cov kev daws muaj raws li hauv qab no:
(1) cov xim diffusion tsis zoo, qhov teeb meem no feem ntau ua rau sprue ze ntawm tus qauv.
(2) thermal stability los yog xim tha xim tsis zoo, kom tswj tau qhov chaw ntawm cov xim, yuav tsum tau ua kom ruaj khov, tsis hais cov khoom kub, cov khoom siv ntau thiab cov voj voog ntau lawm.
(3) Rau cov yas crystallized, sim ua qhov ntawm cov cua txias npaum li cas, rau phab ntsa thickness sib txawv ntawm qhov chaw, siv tau cov xim kom npog xim txawv, rau phab ntsa thickness yog ntau yam nrawm rau kho cov khoom siv thiab pwm kub.
(4) Daim ntawv molding thiab tshuaj pleev ntawm lub chaw ua haujlwm, qhov chaw muaj feem xyuam rau qhov filling qhov teeb meem, ua rau qee qhov ntawm cov khoom ua haujlwm ua xim txawv, nws yuav tsum muab kho yog tsim nyog.
Kev soj ntsuam ntawm cov laj thawj ntawm cov xim thiab gloss ntawm txhaj tshuaj molded khoom feem ntau, cov gloss ntawm qhov ntawm cov tshuaj moulded cov khoom yog tsuas yog txiav txim siab los ntawm hom yas, xim thiab qhov kawg tag. Tab sis feem ntau kuj yog vim muaj ntau qhov laj thawj ntawm cov xim ntawm cov khoom thiab cov teeb meem tsis sib xws, qhov tsaus nti ntawm qhov tsaus ntuj.
Qhov ua rau thiab cov kev daws teeb meem yog raws li nram no:
(1) cov pluag pwm pluaj, pwm txheej xeb, pwm pa ua tsis zoo.
(2) Yog tias lub kaw lus ntawm lub pwm muaj qhov tsis xws, qhov txias txias yuav tsum raug nce, thiab qhov kev tso tawm ntawm cov kabmob, kev sibtshaj kev sibcais, kev nkag mus rau lub cev thiab lub qhovrooj yuavtsum tau nce.
(3) cov khoom kub thiab pwm kub tsawg tsawg, yog tias tsim nyog, qhov chaw siv cua sov ntawm lub qhov rooj tuaj yeem siv tau.
(4) Kev ua haujlwm tsis tshua muaj siab, qeeb qeeb, tsis txaus sijhawm, tsis txaus rov qab, ua rau qhov tsis zoo thiab tsaus nti.
(5) Cov yas kom haum, tab sis kom tsis txhob degradation ntawm cov khoom, cov cua sov yuav tsum ruaj khov, txias kom txaus, tshwj xeeb tshaj yog tuab phab ntsa.
(6) Tiv thaiv txias khoom rau hauv qhov chaw, yog tias tsim nyog, siv lub caij nplooj ntoos hlav thaiv tus kheej los yog lub ntsuas kub tsawg dua.
(7) Khoom siv ntau dhau los, cov khoom tsis zoo los sis cov xim tsis zoo, sib xyaw nrog dej pa los yog lwm cov impurities, tsis zoo roj nplua nyeem.
(8) Lub clamping force yuav tsum txaus.
