Yuav ua li cas txheeb xyuas yog tias ib yam khoom yog tsim los ntawm kev txhaj tshuaj molding?

1, Saib xyuas cov tsos mob
1. Pwm kab cim
Thaum lub sij hawm txhaj tshuaj molding txheej txheem, yas yaj yog txhaj rau hauv lub pwm kab noj hniav los ntawm lub sprue ntawm pwm thiab ua cov khoom tom qab txias. Thaum lub sij hawm tus txheej txheem no, cov pwm kaw kab yuav tawm cov cim ntawm cov khoom, hu ua "pwm kab cim" los yog "parting kab". Cov kab no feem ntau yog nyob ntawm cov khoom sib txuas, xws li ob sab ntawm cov xov tooj, hauv qab ntawm lub rooj zaum, thiab lwm yam. Los ntawm kev ua tib zoo saib cov kab no, peb tuaj yeem txiav txim siab ua ntej seb cov khoom puas yog los ntawm kev txhaj tshuaj molding.
2. Cov cim rooj vag
Lub sprue yog ib qho channel uas txuas lub nozzle ntawm lub tshuab txhaj tshuaj molding mus rau lub pwm kab noj hniav, siv los txhaj cov yas yaj rau hauv pwm. Tom qab txhaj tshuaj molding tiav lawm, ib lub qhov me me los yog protrusion yuav raug tso rau ntawm lub qhov rooj, uas yog hu ua "gate mark". Txawm hais tias qee cov khoom lag luam raug tshem tawm lub rooj vag hauv cov txheej txheem tom ntej, cov kab zoo tseem tuaj yeem pom hauv qee qhov chaw thaum ua tib zoo saib. Cov cim no yog ib qho ntawm cov cim tseem ceeb ntawm kev txhaj tshuaj molded khoom.
3. Uniformity thiab glossiness
Txhaj tshuaj molded khoom feem ntau muaj cov phab ntsa tuab thiab du glossiness. Vim yog cov yas yaj sau cov pwm kab noj hniav nyob rau hauv lub siab thiab ceev ceev txias thiab solidifying, cov tsos ntawm cov khoom yog feem ntau zoo huv si thiab zoo ib yam. Piv txwv li, cov khoom uas tsis yog txhaj tshuaj molded (xws li tshuab moulded, lub tshuab nqus tsev tsim, thiab lwm yam) tuaj yeem pom ntau qhov tsis sib xws thiab qhov tsis xws luag.
2, Tshawb xyuas cov ntaub ntawv thiab cov qauv
1. Kev xaiv cov khoom siv
Kev txhaj tshuaj molding tshuab siv tau rau ntau yam ntaub ntawv yas, suav nrog polypropylene (PP), polystyrene (PS), polycarbonate (PC), thiab lwm yam. Yog li ntawd, thaum peb pom cov khoom yas, peb tuaj yeem txiav txim siab ua ntej seb nws cov khoom puas haum rau kev txhaj tshuaj molding. Tau kawg, qhov no yuav tsum muaj kev paub txog cov ntaub ntawv yas ua lub hauv paus.
2. Internal qauv
Cov qauv sab hauv ntawm kev txhaj tshuaj molded cov khoom yog feem ntau ze rau lawv cov tsos. Piv txwv li, sab hauv qhov cuab lub zog ribs, inserts, thiab lwm yam qauv ntawm cov khoom yog tsim los kom tau raws li cov kev xav tau kev pab. Los ntawm kev tshem tawm lossis saib xyuas cov qauv sab hauv ntawm cov khoom los ntawm kev pom, peb tuaj yeem paub meej ntxiv seb nws puas tau ua los ntawm kev txhaj tshuaj molding. Tsis tas li ntawd, sab hauv ntawm kev txhaj tshuaj molded cov khoom feem ntau nthuav tawm cov yam ntxwv thiab cov qauv ntom ntom.
3, nkag siab txog cov txheej txheem tsim khoom
1. Kev txhaj tshuaj molding txheej txheem
Nkag siab txog cov txheej txheem tseem ceeb ntawm kev txhaj tshuaj molding pab peb txheeb xyuas cov khoom txhaj tshuaj molded zoo dua. Kev txhaj tshuaj molding feem ntau suav nrog cov kauj ruam xws li yas melting, txhaj tshuaj molding, txias thiab solidification, thiab demolding. Thaum lub sijhawm txheej txheem no, cov yas yaj tau nrawm nrawm rau hauv cov pwm kab noj hniav nyob rau hauv siab siab thiab puv tag nrho qhov chaw. Los ntawm kev soj ntsuam cov txheej txheem ntau lawm ntawm cov khoom lossis kev sab laj nrog cov chaw tsim khoom, peb tuaj yeem tau txais cov ntaub ntawv ntau ntxiv txog seb cov khoom puas tsim los ntawm kev txhaj tshuaj molding.
2. Pwm tsim thiab tsim khoom
Kev tsim pwm thiab kev tsim cov khoom txhaj tshuaj molded yog ib qho tseem ceeb ntawm kev txiav txim siab cov khoom zoo. Qhov tseeb, lub zog, thiab durability ntawm cov pwm ncaj qha cuam tshuam rau cov tsos, qhov loj me, thiab kev ua haujlwm ntawm cov khoom. Yog li ntawd, los ntawm kev soj ntsuam cov pwm tsim ntawm cov khoom lossis nkag siab nws cov pwm tsim pwm, peb tuaj yeem txiav txim siab ncaj qha seb cov khoom puas tsim los ntawm kev txhaj tshuaj molding.
4, Kev sib xyaw ua ke nrog cov txheej txheem siv tswv yim
1. Cov khoom siv hauv tsev thiab txhua hnub
Hauv cov khoom siv hauv tsev, ntau yam khoom yas xws li lub raj mis dej, cov tais diav, cov thawv ntim khoom, thiab lwm yam yog tsim los ntawm kev txhaj tshuaj molding. Cov khoom no feem ntau muaj cov yam ntxwv xws li cov phab ntsa tuab, du nto, thiab pom tseeb pwm kab. Los ntawm kev soj ntsuam cov yam ntxwv no thiab sib txuas nrog cov ntaub ntawv siv tiag tiag thiab cov ntaub ntawv ntawm cov khoom, peb tuaj yeem yooj yim txheeb xyuas cov khoom txhaj tshuaj molded.
2. Kev lag luam thiab cov khoom siv tsheb
Txhaj tshuaj molding tshuab kuj tau siv dav hauv kev lag luam thiab kev tsim tsheb. Ntau yam khoom siv yas xws li iav, bearings, connectors, thiab lwm yam yog tsim los ntawm kev txhaj tshuaj molding. Cov khoom no feem ntau muaj cov txheej txheem nyuaj thiab cov kev xav tau loj. Los ntawm kev soj ntsuam cov yam ntxwv ntawm cov qauv, xaiv cov khoom siv, thiab cov txheej txheem tsim khoom ntawm cov khoom, peb tuaj yeem paub meej ntxiv seb nws puas yog los ntawm kev txhaj tshuaj molding.
