Ntau ntxiv txog kev tso cov rooj vag thiab txhaj tshuaj molding sprue thiab cov khoom ntws

Muab cov rooj vag thiab txhaj tshuaj molding sprue yog ib feem tseem ceeb ntawm cov txheej txheem txhaj tshuaj molding.Kev tso kawm ntawm cov khoom no tuaj yeem cuam tshuam qhov zoo ntawm cov khoom kawg, nrog rau kev ua haujlwm ntawm cov txheej txheem.Hauv tsab xov xwm no, peb yuav tshawb nrhiav ntau ntxiv txog kev tso cov rooj vag thiab kev txhaj tshuaj molding sprue, nrog rau cov khoom ntws thiab yuav ua li cas tso cua kom nyab xeeb.

Ua ntej, cia peb nkag siab tias lub rooj vag thiab kev txhaj tshuaj molding sprue yog dab tsi.Lub rooj vag yog qhov qhib me me hauv pwm los ntawm cov yas molten yog txhaj.Qhov loj thiab qhov chaw ntawm lub rooj vag tuaj yeem cuam tshuam cov khoom ntws thiab qhov kawg ntawm cov khoom zoo.Kev txhaj tshuaj molding sprue yog cov channel uas cov yas molten nkag mus rau hauv pwm kab noj hniav.

Qhov chaw ntawm lub rooj vag thiab txhaj tshuaj molding sprue yog qhov tseem ceeb hauv kev txhaj tshuaj molding txheej txheem.Qhov chaw ntawm lub rooj vag yuav tsum tau ua tib zoo xaiv los xyuas kom meej tias cov yas ntws sib npaug thoob plaws hauv cov pwm kab noj hniav, thiab qhov seem puv tag.Yog tias lub qhov rooj me me dhau lawm, cov yas yuav tsis ntws zoo, ua rau tsis tiav ntawm cov pwm kab noj hniav, ua rau muaj qhov tsis xws luag hauv cov khoom kawg.Yog tias lub rooj vag loj dhau lawm, nws tuaj yeem tso cov cim pom ntawm cov khoom kawg, hu ua gate vestiges.

Cov khoom ntws yog lwm qhov tseem ceeb hauv kev txhaj tshuaj molding txheej txheem.Cov yas molten yuav tsum tau ntws tusyees thoob plaws hauv cov pwm kab noj hniav kom paub meej tias cov khoom ntim tag nrho.Yuav kom ua tiav qhov no, kev txhaj tshuaj molding sprue yuav tsum tau muab tso rau hauv qhov chaw uas tso cai rau cov yas ntws sib npaug thoob plaws hauv cov pwm kab noj hniav.Lub sprue kuj yuav tsum muaj qhov loj txaus kom tso cai rau cov yas ntws yooj yim.

Txhawm rau kom ntseeg tau tias cov yas ntws sib npaug thoob plaws hauv cov pwm kab noj hniav, cov pwm tsim yuav tsum tau ua kom zoo dua.Cov qauv tsim yuav tsum muaj cov yam ntxwv xws li cov phab ntsa tuab, uas yuav pab xyuas kom cov yas ntws sib npaug thoob plaws hauv cov pwm kab noj hniav.Cov pwm kuj tseem yuav muaj lub kaum sab xis txaus, uas yuav pab xyuas kom meej tias cov pwm tuaj yeem yooj yim tshem tawm ntawm pwm.

Cua tso tawm yog lwm qhov tseem ceeb hauv kev txhaj tshuaj molding txheej txheem.Cua daig hauv pwm tuaj yeem ua rau muaj qhov tsis xws luag hauv cov khoom kawg.Txhawm rau tso cua kom nyab xeeb, cov pwm yuav tsum muaj cov pa tawm uas tso cai rau huab cua kom dim.Cov venting channel yuav tsum tau muab tso rau hauv lub tswv yim los xyuas kom meej tias huab cua tuaj yeem khiav tawm yam tsis muaj kev cuam tshuam rau qhov kawg ntawm cov khoom zoo.

Hauv kev xaus, tso cov rooj vag thiab txhaj tshuaj molding sprue yog ib feem tseem ceeb ntawm txoj kev txhaj tshuaj molding.Lub rooj vag qhov chaw thiab qhov loj me, nrog rau kev txhaj tshuaj molding sprue qhov kev tso kawm, tuaj yeem cuam tshuam cov khoom ntws thiab cov khoom kawg qhov zoo.Cov pwm tsim yuav tsum tau ua kom zoo dua los xyuas kom meej tias cov yas ntws sib npaug thoob plaws hauv cov pwm kab noj hniav, thiab cov pwm yuav tsum muaj cov cua tso tawm kom zoo.Los ntawm kev xyuam xim rau cov xwm txheej no, tuaj yeem tsim cov khoom txhaj tshuaj molded zoo.
