Vim tias qhov sib txawv molding tuag tau siv rau hauv ntau qhov chaw, ua ke nrog kev tsim cov pwm tsim tshuab hauv xyoo no, muaj qee qhov kev hloov pauv thiab kev tsim kho.
Yog li ntawd, nyob rau hauv seem no, cov kev cai dav dav tsim ntawm lub tshuab nqus tsev nqus molding tuag tau sau tseg.Kev tsim ntawm lub tshuab nqus tsev molding pwm suav nrog batch loj, cov khoom siv molding, precision tej yam kev mob, geometric duab tsim, qhov ntev stability thiab nto zoo.
1. Rau batch loj thwmsim, cov pwm tso zis yog me me, thiab nws yuav ua tau los ntawm ntoo los yog resin.Txawm li cas los xij, yog tias qhov kev sim pwm yog kom tau txais cov ntaub ntawv hais txog qhov shrinkage, qhov ruaj khov, thiab lub sij hawm voj voog ntawm cov khoom, ib kab noj hniav pwm yuav tsum tau siv rau qhov kev sim, thiab nws tuaj yeem lav tau siv raws li kev tsim khoom.Pwm feem ntau yog ua los ntawm gypsum, tooj liab, txhuas, lossis txhuas-steel alloys, thiab aluminium-resin tsis tshua siv.
2. Geometric duab tsim.Thaum tsim, nco ntsoov xav txog qhov ruaj khov thiab qhov zoo ntawm qhov chaw.Piv txwv li, cov khoom tsim thiab qhov kev ruaj ntseg yuav tsum tau siv cov poj niam pwm (concave pwm), tab sis cov khoom uas muaj ntau dua nto gloss yuav tsum tau siv cov txiv neej pwm (convex pwm).Nyob rau hauv txoj kev no, tus neeg yuav khoom yas yuav txiav txim siab ob qho tib si Point kom cov khoom tuaj yeem tsim nyob rau hauv qhov kev pom zoo.Kev paub dhau los tau ua pov thawj tias cov qauv tsim uas tsis ua raws li kev ua haujlwm tiag tiag feem ntau ua tsis tiav.
3. Dimensional stability.Thaum lub sij hawm molding txheej txheem, kev sib cuag nto ntawm cov yas nrog pwm yog zoo dua li qhov seem stability ntawm qhov seem tawm hauv pwm.Yog hais tias lub thickness ntawm cov khoom yuav tsum tau hloov nyob rau hauv lub neej yav tom ntej vim lub rigidity ntawm cov khoom, cov txiv neej pwm yuav hloov mus rau hauv ib tug poj niam pwm.Qhov ntev ntev ntawm cov khoom yas yuav tsum tsis pub tsawg tshaj 10% ntawm qhov shrinkage.
4. Qhov saum npoo ntawm cov yas, kom deb li deb ntawm cov khoom siv molding tuaj yeem npog, cov qauv ntawm qhov pom ntawm cov yas yuav tsum tau tsim nyob rau hauv kev sib cuag nrog pwm.Yog tias ua tau, tsis txhob kov lub npoo du ntawm cov yas nrog cov pwm nto.Nws zoo li rooj plaub ntawm kev ua cov dab da dej thiab ntxhua khaub ncaws nrog cov pwm tsis zoo.
5. Kev hloov kho.Yog hais tias lub clamping ntug ntawm cov yas yog saws tawm nrog ib tug neeg kho tshuab kab rov tav saw, yuav tsum muaj tsawg kawg yog 6 mus rau 8 hli nyob rau hauv qhov siab kev taw qhia.Lwm yam kev hnav khaub ncaws ua haujlwm, xws li kev sib tsoo, laser txiav, lossis jetting, yuav tsum tso cai rau cov npoo.Qhov sib txawv ntawm qhov txiav ntawm qhov txiav ntug tuag yog qhov tsawg tshaj plaws, thiab qhov dav ntawm qhov xuas nrig ntaus tuag thaum trimming kuj yog me me.Cov no yuav tsum tau them nyiaj rau.
6. shrinkage thiab deformation.Cov yas yog yooj yim rau shrinkage (xws li PE).Qee qhov khoom yas yog yooj yim rau deform.Txawm hais tias yuav tiv thaiv lawv li cas, cov khoom yas yuav deform thaum lub caij txias.Nyob rau hauv cov xwm txheej no, nws yog ib qho tsim nyog yuav tsum tau hloov cov duab ntawm kev tsim pwm kom hloov mus rau qhov sib txawv ntawm qhov geometric ntawm cov yas.Piv txwv li: Txawm hais tias cov phab ntsa ntawm cov yas yog khaws cia ncaj, nws qhov chaw siv tau deviated los ntawm 10mm;pwm puag tuaj yeem raug tsa los kho qhov shrinkage ntawm no deformation.
7.Shrinkage, cov nram qab no shrinkage yam yuav tsum tau coj mus rau hauv tus account thaum tsim cov yas forming pwm.
①Cov khoom molded shrinks.Yog hais tias lub shrinkage ntawm cov yas tsis tuaj yeem paub meej, nws yuav tsum tau kuaj los yog tau los ntawm kev sim nrog cov pwm zoo sib xws.Nco tseg: Tsuas yog shrinkage tuaj yeem tau los ntawm txoj kev no, thiab deformation loj tsis tuaj yeem tau.
②Shrinkage tshwm sim los ntawm qhov tsis zoo ntawm cov xov xwm nruab nrab, xws li ceramics, silicone roj hmab, thiab lwm yam.
③Lub shrinkage ntawm cov ntaub ntawv siv hauv pwm, xws li shrinkage thaum casting txhuas.
