Urethane Nqus Plua Plav Casting

CreateProto, nyob ntawm ntug kev nqus ntawm lub tshuab nqus tsev casting tshuab, tuaj yeem tsim cov roj hmab silicone pwm ua cov txheej txheem urethane cam khwb cia qhov nrawm thiab nrawm. Cam khwb cia urethane los ntawm cov txheej txheem no yog qhov zoo tshaj plaws los kuaj ua ntej ntu khoom, kev ua haujlwm, thiab kev tsim pov thawj.

Kev Yoo Qiv-Cov Qiv Ntau Lawm Xaiv: Cov Khoom Siv Me Me Txhaws Yas

CreateProto lub tshuab nqus tsev casting tshuab muaj ntau yam khoom siv los pab txhawb kev tsim cov cam urethane qhov chaw, feem ntau rau kev kuaj xyuas qhov ntsuas, kev ntsuas ua ntej kev tsim khoom thiab cov ntim qis. Cov nplai urethane seem tau nrawm thiab pheej yig yam tsis tas yuav tsum nqis peev cov khoom siv hlau thaum cov khoom tsuas yog ntau lub sijhawm luv luv, thiab tuaj yeem xa tawm nyob rau hauv ntau lub sijhawm.

Lub tshuab nqus tsev casting (tseem hu ua polyurethane casting) tuaj yeem siv kom ze rau kev sim txhaj tshuaj moulded qhov kawg lossis cov khoom tiav. Feem ntau, cov pwm no yog tsim los ntawm roj hmab silicone thiab siv CNC los yog SLA ntu ua qauv qauv. Cov pwm no theej tawm cov ntsiab lus thiab ntxaij thiab muab cov ua tiav zoo ib yam los ntawm ib ntu mus rau lwm qhov. Koj tuaj yeem tau cov txiaj ntsig zoo li kev tsim tawm nrog rau cov neeg kho tshuab, xim, thiab ua kom tiav.

Nrog 20 xyoo kev paub, Createproto cov kws tshaj lij pab neeg muab kev pabcuam lub tshuab nqus tsev zoo rau ntim ntim yas ua ntej, thiab pab koj ua kom muaj qhov sib txig sib luag ntawm cov khoom zoo, qhov kawg siv thiab cov khoom siv txhuas lub sijhawm. Nrhiav cov ntaub ntawv ntxiv txog peb cov txheej txheem nqus casting, koj tuaj yeem thov cov lus sau rau ntawd.

Ua Xib Hwb Pattens rau Urethane Casting

Qhov zoo ntawm cov qhov chaw casting yog txiav txim siab los ntawm qhov zoo ntawm tus qauv, thiab feem ntau ntawm cov masters feem ntau yog machined los ntawm CNC thaum koj xav tuav nruj thev taus ntev xws li +/- 0.05mm. Ib qho ntxiv, peb tseem yuav txiav txim siab ua tus tswv los ntawm SLA rau cov ntu ntawd nrog cov qauv sib xyaw. Lub tshuab CNC siv sijhawm ntev dua thiab siv nyiaj ntau dua los ua tus tswv, thaum lub SLA tuaj yeem tsim cov masters sai dua, thiab tuaj yeem ua kom cov qauv sib dhos ua kom tau raws li qhov raug thiab raug.

Qhov ntau npaum li cas ntawm tus masters yog raws li tag nrho cov khoom siv ntawm qhov ua tiav casting xav tau thaum kawg. Yog tias qhov casting ntau yog tsuas yog ob peb daim xwb, tom qab ntawd ib tus tswv yuav txaus, thaum yog tias qhov ntau yog dhau 30 daim, hauv kev xav txog lub sijhawm khoom xa tuaj, peb yuav ua tiav 1-2 tus tswv kom peb tuaj yeem ua ntau silicone pwm ua qhov casting qhov chaw sai dua.

Thaum qhov yuav tsum tau ntawm tus neeg tau txais txiaj ntsig siab, siab dhau qhov chaw tiav lossis txawm tias qhov chaw tsis pom tseeb, tus qauv tsim yuav raug tsim nrog CNC tshuab uas yog cim nrog siab specification precision machining thiab zoo nto tiav.

Qhov kev tshaj lij polished qhov chaw yuav ci tiav thiab kho qhov muag pom tseeb. Lub caij no, peb kuj tuaj yeem pleev xim xim sab nrauv rau kev ntxhib los mos los yog satin nyhuv rau simulate pwm kawg kev ntxhib los mos ntawm cov khoom. Cov pwm pwm yuav luam tawm cov ntsiab lus thiab cov qauv ntawm tus tswv qub, yog li ntawd cov seem casting yuav tawm tuaj tib yam li tus tswv tsis muaj qhov ua tiav ntawm qhov chaw.

Silicone Roj Hmab Ua

Cov silicone pwm pwm (tseem hu ua RTV pwm) yog tsim raws cov qauv qauv. Tshuaj lom neeg ruaj khov, cov khoom tso tawm ntawm tus kheej thiab qhov yooj yim ntawm silicone roj hmab yog zoo heev uas nws muab tsawg kawg shrinkage thiab nqa cov ntsiab lus zoo tau txais txiaj ntsig los ntawm cov tswv rau pwm.

Lub neej siv ntawm silicone pwm yog ncaj qha cuam tshuam rau qhov nyuaj ntawm qhov nrum qhov. Feem ntau, nws tawm 12-15 daim ua ntej ua rau tsis zoo. Yog tias cov qauv ntawm ntu yog yooj yim, ib qho pwm tuaj yeem tuaj yeem 20 qhov; thaum yog tias ib feem yuav tsum tau ua kom zoo xws li cov tshooj tsis meej uas tsis yooj yim, ib qho pwm tsuas tuaj yeem ua 12 lossis txawm tias 10 casting seem.

Cov kauj ruam los ua Cov Silicone Roj Hmab Tuaj pwm

  • Tus tswv yuav tsum tau daig nrog qee zaj yeeb yaj kiab kom ua kom cov pwm yooj yim kom txiav, uas yuav ua yeeb yam rau lub npoo rau cov pwm kawg.
  • Tus qauv ntawm cov tub ntxhais raug muab tshem tawm hauv ib lub thawv uas muaj lub rooj vag thiab lub raj xa nrog; cov risers tau muab tso rau ntawm ntu kom cov huab cua khiav tawm ntawm cov pwm kawg.
  • Silicone tau nchuav thoob plaws tus tswv thiab lub tshuab nqus tsev yog siv los tshem tag nrho cov huab cua. Qhov no ces yog kho rau hauv qhov cub, qhov kub ntawm 40 ℃. Nws feem ntau siv sijhawm 8-16 teev nyob ntawm seb qhov ntim ntawm qhov pwm.
  • Thaum cov roj hmab silicone tau kho, lub thawv thiab cov ris tau tshem tawm; raws li tus tswv tshem tawm los ntawm silicone los tsim kab noj hniav, silicone roj hmab pwm yog tsim.

Polyurethane Casting Txheej Txheem Nthuav Qhia

Polyurethane casting tuaj yeem ua tau raws cov neeg tau txais kev pom zoo, tsis muaj teeb meem hauv cov xim, kev ntxhib los mos thiab ci tiav, ntxig thiab dhau molding, lossis txawm tias tsis muaj qhov pom tseeb.

Cov txheej txheem tsim cov qauv kev ua haujlwm raug cai ua kom paub tseeb qhov tseeb ntawm qhov seem ntawm tus qauv thiab cov khoom txhua yam. Peb cov kws kho tshuab casting tswj txhua qhov kev ua haujlwm: sib xyaw, de-gassing, nplawm, preheating, casting thiab de-molding, tso cai rau cov ntawv luam ze ntawm qhov qauv ntawm tus qauv tsim, thiab muab cov qauv kev zam rau ± 0.15mm / 100mm, nrog lub siab zoo tshaj plaws muaj peev xwm ncav cuag ± 0.05 hli.

Cov kauj ruam rau Urethane Casting Txheej Txheem

  • Kev npaj ua ntej-theem, cov pwm silicone tso rau hauv qhov cub thiab rhaub kom kub li 60 ° C-70 ° C.
  • Muab cov pwm ua ntej nrum cov polyurethane. Xaiv txoj cai pwm-tso tus neeg sawv cev (thiab siv nws kom raug) yog qhov tseem ceeb heev uas yuav tsum ua kom tsis txhob lo nplaum thiab qhov chaw tsis zoo.
  • Npaj cov polyurethane resins rau preheat nws txog li 40 ° C ua ntej siv. Sib tov ob-xaim hluav taws xob hauv qhov sib npaug kiag, thiab tom qab ntawd kom tag nrho do thiab degas rau 50-60 vib nas this hauv qab nqus tsev.
  • Cov dej nplaum tau nchuav mus rau hauv cov pwm hauv chav nqus tsev hauv qab tswj hwm lub computer, thiab kho dua hauv qhov cub. Qhov sij hawm kho mob nruab nrab: 1-3 teev rau qhov chaw me me thiab 3-6 teev rau qhov loj.
  • Tshem tawm cov khoom siv tawv ib sab ntawm silicone pwm tom qab kho. Tshem tawm cov rooj vag thiab qhov cua; tawm qhov tseeb luam ntawm daim tseem.
  • Npaj kom rov ua lub voj voog no.
