Cov yam ntxwv ntawm cov txheej txheem txhaj tshuaj molding rau ob -xim khoom yog raws li nram no.
Ob -xim txhaj tshuaj molding tshuab feem ntau yog nruab nrog ob lossis ntau txheej ntawm cov khoom siv yas txhaj tshuaj. Cov qauv ntawm lub tshuab txhaj tshuaj (xws li thaum uas tig mus thiab unidirectional, thaum uas tig mus thiab tawm tsam, L- zoo li tus, thiab lwm yam) thiab pwm clamping mechanism (xws li hom teb, rotating ncej hom, thiab lwm yam) yuav tsum tau sib phim raws li cov txheej txheem ntau lawm. [3] Lub nozzle yuav tsum muaj cov qauv tshwj xeeb raws li txoj kev tsim khoom, los yog yuav tsum tau nruab nrog ob txheej molding pwm nrog tib cov qauv uas tuaj yeem tig thiab rov ua haujlwm. Thaum lub sij hawm yas txhaj tshuaj, cov txheej txheem tsis xws li yaj kub, txhaj tshuaj, thiab txhaj tshuaj yaj ntim hauv ob pawg ntawm cov khoom siv yas txhaj tshuaj yuav tsum zoo ib yam.
Piv nrog rau cov khoom siv yas txhaj tshuaj zoo tib yam, ob- xim txhaj tshuaj molded yas cov khoom yuav tsum muaj ntau dua rau qhov kub thiab txias thaum txhaj tshuaj. Qhov laj thawj tseem ceeb yog vim li cas cov pwm ntws channel hauv ob - xim txhaj tshuaj molding yog qhov ntev thiab cov qauv yog qhov nyuaj, ua rau muaj kev tiv thaiv ntau dua rau yaj ntws.
Ob - xim txhaj tshuaj molded yas cov khoom yuav tsum siv raw cov ntaub ntawv uas muaj thermal stability thiab tsawg yaj viscosity kom tsis txhob decomposition vim kub melting kub thiab nyob ntev lub sij hawm nyob rau hauv lub ntws channel. Cov yas siv feem ntau suav nrog polyolefin resins, polystyrene, thiab ABS. Kev xaiv cov khoom siv yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm cov nplaum nplaum thiab kev ua tau zoo. Txhawm rau kom muaj kev sib raug zoo, cov khoom sib txuas nrog cov saw hlau sib txuas (xws li PC thiab TPU) feem ntau xaiv, thiab qhov sib txawv ntawm qhov sib txawv ntawm ob cov ntaub ntawv feem ntau yuav tsum muaj ntau dua lossis sib npaug li 30℃kom tsis txhob delamination.
Hauv kev txhaj tshuaj molding ntawm ob- xim yas khoom, kom ntseeg tau tias zoo fusion ntawm ob lub xim sib txawv hauv cov pwm thiab lav lub molding zoo ntawm cov khoom txhaj tshuaj molded, siab melting kub, siab pwm kub, siab txhaj tshuaj molding, thiab ntau dua txhaj tshuaj yuav tsum tau siv.
Cov kev tshawb fawb tau pom tias cov txheej txheem tseem ceeb (kwv yees, tuav lub zog, txhaj tshuaj ceev, thiab pwm kub) muaj qhov cuam tshuam loj rau cov khoom zoo (xws li ntim ntim thiab qhov shrinkage Performance index), thiab qhov kev txiav txim ntawm lawv cov cawv tau txiav txim siab ua ntej los ntawm kev sim. Tsis tas li ntawd, cov txheej txheem no muaj lub qhov rais nqaim, yuav tsum muaj kev tswj xyuas cov khoom kub thiab kev txhaj tshuaj; Piv txwv li, qhov sib txawv ntawm qhov kub ntawm ± 5℃ntawm cov ntaub ntawv mos thiab tawv tawv tuaj yeem ua rau 30% txo qis hauv kev sib khi lub zog.
Cov pwm tsim yog qhov tseeb thiab cov qauv yog tshwj xeeb, feem ntau nruab nrog siab -precision rotating los yog zawv zawg mechanisms, xws li turntable coaxiality yuav tsum tau tsawg dua los yog sib npaug rau 0.005mm. Cov yas tawv tawv feem ntau yog tsim los nrog dovetail grooves, micro- qhov arrays, thiab lwm yam kev sib cuam tshuam cov qauv, thaum lub rooj vag yas mos yuav tsum tsis txhob muaj qhov tsis muaj zog ntawm kev sib cog lus ntawm cov yas tawv thiab mos kom ua tiav cov khoom sib txuas ntawm cov khoom thiab xyuas kom muaj kev sib raug zoo.
Tsis tas li ntawd, piv rau kev txhaj tshuaj molding, ob - xim txheej txheem molding muaj qhov cuam tshuam ntau dua thiab cuam tshuam nrog kev tsis paub meej xws li kev sib txuas sib txuas, ua rau nws nyuaj rau kev siv CAE software los ua kom tiav thiab nthuav dav simulations. Cov txiaj ntsig simulation feem ntau tsuas yog siv los ua ib qho kev siv rau kev tsim khoom tiag tiag.
