Nqus casting- nchuav polyurethane resin rau hauv ibsilicone cuab tam nyob rau hauv lub tshuab nqus tsev- tau dhau los ua kev hloov pauv ntawm 3D- cov qauv luam tawm thiab cov khoom siv yas ntau lawm. Tab sis nws puas tuaj yeem ua raws li qhov zoo ntawm cov khoom siv hluav taws xob xws li ABS, polycarbonate, lossis nylon? Kab lus no tshuaj xyuas qhov zoo uas lub tshuab nqus tsev casting captures zoo; yuav ua li cas nws lub zog piv rau engineering thermoplastics; yuav ua li cas cua sov tus cwj pwm thiab shrinkage cuam tshuam qhov tseeb; thiab kev xaiv cov khoom siv zoo li cas ua rau muaj kev ua tau zoo tshaj plaws.
Cov khoom siv twg tuaj yeem nqus tau Casting Reproduce tseeb?
Shore Hardness thiab Flexibility
Qhov zoo tshaj plaws repeatability ntawm lub tshuab nqus tsev casting yog nyob rau hauv hardness. Cov txheej txheem polyurethane niaj hnub no tuaj yeem tsim los ntawm cov roj hmab mos- zoo li qib ntawm 30 Shore A mus rau cov khoom sib xyaw ua ke ze ze ntawm 85 Shore D, ua rau cov kws ua choj rov ua dua ib yam dab tsi los ntawm TPE grips mus rau ABS cov vaj tse nyuaj. Lub hardness yog ib feem ntawm cov resin chemistry nws tus kheej; Yog li ntawd, txhua tus duplicate coj los ntawm tib lub cuab yeej silicone muaj qhov ruaj khov thiab rov ua dua tus nqi hardness.
Nto Finish thiab Optical Clarity
Silicone pwm ntes txhua yam ntawm tus qauv tsim yog li ntawdlub tshuab nqus tsev- nrum qhov chawnquag muaj qhov chaw uas tsis tas yuav ua kom tiav tag nrho: siab gloss, zoo nkauj, engraved sau, los yog xim -matched pigmentation ncaj qha los ntawm lub cuab yeej. Nrog cov pob tshab thiab xim xim, txoj kev tuaj yeem ua tiav duplicate PMMA thiab polycarbonate optics, ua kom nws zoo meej rau lub lens npog, tso saib qhov rais, thiab qhia- cov qauv zoo uas yuav tsum tshwm sim raws li qhov kawg.
Elasticity thiab elongation
Lub tshuab nqus tsev casting tuaj yeem txuas ntxiv los tsim cov khoom siv tau yooj yim siv elastomeric polymers. Roj hmab-zoo li polyurethanes muaj elongation ntawm kev tawg deb tshaj li ib puas feem pua thiab rov qab coj tus cwj pwm zoo li kev txhaj tshuaj- pwm TPE thiab TPU, uas ua raucov ntsaws ruaj ruaj, gaskets, hauv qab, thiabdhau -moulded soft- kov gripsyuav tsum tau tshuaj xyuas qhov tseeb ua ntej yuav txiav cov cuab yeej nyuaj. Qhov loyalty rau manufacturing elastomers yog lub zog tiag tiag ntawm cov txheej txheem.
Yuav Ua Li Cas Hardness thiab Strength piv nrog Engineering Plastics?
Tensile Strength Benchmarks
Cam khwb cia polyurethanes rau kev siv dav dav tuaj yeem ua tiav lub zog tensile ntawm ib ncig ntawm 45 txog 70 MPa. Qhov no yog nyob rau hauv tib lub ballpark li ABS ntawm txog 45 MPa thiab ze rau ntau lub iav - puv nylons rau prototyping. Rau feem ntau cov kev xeem ua haujlwm, clips, vaj tse, thiab brackets,nqus castingmuab cov ntaub ntawv muaj zog txaus kom paub meej tias tus qauv tsim ntev ua ntej cog lus rau kev txhaj tshuaj pwm raug nqi.
Impact Resistance thiab Toughness
Cov qib toughened polyurethane tau tsim los muab kev poob siab thiab ua rau muaj kev cuam tshuam tus cwj pwm tsim nyog rau kev sim poob, kev sim sib dhos, thiab kev soj ntsuam ntawm cov neeg siv khoom thiab cov khoom lag luam. Lub tshuab nqus tsev casting ib puag ncig kom ntseeg tau tias tsis muaj cua los yog npuas. Qhov no txhais tau tias cov khoom cam khwb cia muaj huv si, zoo ib yam hardness los ntawm thawj daim ntawv luam nyob rau hauv ib batch mus rau lub xeem kawg.
Load-Cov Kabmob thiab cov qauv tsim
Siv nruj, siab -modulus resins nyob rau hauv lub tshuab nqus tsev casting txhais tau tias koj tuaj yeem ua cov khoom siv tiag tiag, xws li cov ntaub thaiv npog, cov phaj mounting, ducting thiab sib dhos jigs, uas ua rau muaj kev ntxhov siab tiag tiag thaum kuaj. Cov neeg tsim qauv kuj tseem tuaj yeem ua ke cov thav duab nruj nrog cov mos dua- pwm nyob rau hauv ib lub rooj sib txoos, ua ntau yam - txhaj tshuaj molding sai thiab kev lag luam, txo qis kev loj hlob mus rau cov khoom siv hluav taws xob, khoom siv kho mob, thiab cov khoom siv hauv tsheb.
Lub luag hauj lwm dab tsi ua cov khoom cua sov thiab Shrinkage ua si hauv Nqus Casting?
Thaum tshav kub kub Deflection kub
Cov txheej txheem polyurethanes tuaj yeem siv tsis tu ncua ntawm 60 txog 80 degree, tab sis siab - qib kev ua tau zoo tam sim no mus txog 120℃lossis siab dua, uas suav nrog kev ua haujlwm ntawm feem ntau cov khoom siv hluav taws xob thiab cov neeg siv khoom vaj tse. Kev qhia lub siab HDT resin pem hauv ntej kom ntseeg tau tias qhov chaw nyob ruaj khov nyob rau hauv kev ntxhov siab rau lub tshuab nqus tsev casting nrog cov kev pabcuam kub.
Shrinkage thiab Dimensional raug
Polyurethane shrinks me ntsis feem ntawm ib feem pua raws li nws hla -txuas, thiab silicone cov cuab yeej yog intrinsically hloov me ntsis; Yog li ntawd, lub tshuab nqus tsev casting feem ntau ua tiav qhov siab ze rau ± 0.1 hli ntawm cov yam ntxwv ntawm microscopic. Cov kws tshaj lij tuaj yeem ntseeg siab ua kom haum- thiab- kev sim ua haujlwm txij li qhov sib txawv ntawm cov ntawv luam yog txo qis los ntawm kev tswj xyuas qhov kub thiab txias, ncuav tus nqi, thiab kho lub sijhawm, ua rau muaj qhov tseeb.
Ncej -Kho thiab khoom ruaj khov
Tshaj tawm - kho hauv qhov cub tswj tau ua tiav cov txheej txheem sib txuas - thiab teeb tsa qhov kawg hardness, lub zog, thiab thermal ua haujlwm ntawm cov resin. Cov kauj ruam no tseem ceeb hauvnqus castingvim tias ib feem uas nyob rau hauv - kho tau tuaj yeem txuas ntxiv mus rau qhov ntev rau hnub tom qab demolding. Ib qho kev tshaj tawm nruj- kev kho niaj hnub ua rau qhov thib nees nkaum zoo ib yam li qhov loj thiab tus cwj pwm zoo li thawj.
Yuav Ua Li Cas Xaiv Cov Khoom Txhim Kho Lub Nqus Casting Performance?
Matching Resin Family to the Target Plastic
Resin muab cov ntaub ntawv teev cov ntaub ntawv raws li ABS-zoo li, PC-zoo li, PP-zoo li, PMMA-zoo li, thiab roj hmab-zoo li, yog li txoj hauv kev nrawm tshaj plaws rau qhov tseeb replica yog pib los ntawm cov ntaub ntawv ntawm cov khoom siv yas thiab xaiv cov tsev neeg sib xws. Qhov kev taw qhia no tso cai rau lub tshuab nqus tsev casting coj kwv yees thaum lub sij hawm sim vim tias qhov tawv, lub zog, thiab cov lus teb saum npoo ntawm daim ntawv ua raws li cov khoom qub.
Filled thiab Specialty Systems
Rau kev thov kev thov, cov tshuab ntim tau tsa lub qab nthab ntawm qhov nqus casting tuaj yeem ua tiav. Iav- los yog ntxhia-polyurethanes ua kom muaj zog thiab qhov ruaj khov rau qhov loj dua, thaum nplaim taws- khoom noj khoom haus, khoom noj- tiv tauj, thiab cov ntawv pov thawj kho mob qhib qhov rooj hauv hluav taws xob, ntim khoom, thiab kev txhim kho cov cuab yeej. Xaiv ib qho tshwj xeeb resin thaum ntxov hauv qhov project tsis txhob raug nqi kho dua tom qab.
Txheej Txheem Kev qhuab ntuas thiab kev txhawb nqa tus khub
Txawm tias qhov zoo tshaj plaws resin xav tau kev qhuab ntuas: kev degassing tag nrho, qhov sib xyaw kom raug, tswj pwm thiab cob qhov kub thiab txias, thiab cov phab ntsa tuab tuab tag nrho cov khoom kawg. Koom tes nrog ib tus kws kho mob uas paub txog xws liWelong- uas nws cov engineers tsim hauv AutoCAD, Pro-Engineer, thiab SolidWorks thiab saib xyuas kev ua tau zoo raws li ISO 9001:2015 - tig lub tshuab nqus tsev casting los ntawm cov txheej txheem kev cob qhia rau hauv cov cuab yeej txhim kho kev vam meej.
