Polyurethane Casting Applications hauv Kev Kho Mob Kev Lag Luam

Puas tau sim kom tau txais cov qauv kev kho mob npaj rau kev sim lossis kev tswj xyuas ntxov hauv ob lub lis piam?

Feem ntau pawg muaj. Koj xav tau ib pawg me me ntawm cov vaj tsev ua haujlwm, tuav, lossis cov khoom sib txuas. Kev txhaj tshuaj molding txhais tau hais tias tos yim mus rau kaum ob lub lis piam thiab them nyiaj rau cov cuab yeej nyuaj uas yuav dhau los ua tsis siv tom qab kev hloov kho tom ntej . 3D luam ntawv nrawm, tab sis qhov zoo thiab cov khoom sib xws feem ntau poob qis ntawm cov kws kho mob lossis pawg pov thawj xav tau.

Qhov sib txawv no yog qhov chaw nqus casting-tseem hu ua polyurethane casting- tau dhau los ua qhov tseem ceeb rau kev txhim kho cov cuab yeej kho mob. Nws muab ntau lawm -zoo liNqus Casting Prototypeshauv cov ntim tsawg, nrog cov ntaub ntawv uas tuaj yeem txhawb nqa biocompatibility yuav tsum tau rau ntau yam sab nraud thiab txwv -hu rau daim ntawv thov.

Cov kev pab cuam kho mob tsis tshua txav mus rau hauv txoj kab ncaj nraim. Feem ntau cov phiaj xwm mus dhau ob mus rau plaub qhov kev ua piv txwv. Txhua qhov kev hloov kho tshuab tuaj yeem siv sijhawm peb mus rau rau lub lis piam thaum koj tso siab rau CNC lossis cov cuab yeej ib txwm siv. Rau cov khoom siv hauv chav kawm II, lub sijhawm tag nrho feem ntau ncav ib mus rau peb xyoos. Kev hloov pauv tsim lig ua rau ob lub sijhawm thiab nyiaj txiag.

Kev txhaj tshuaj molding tseem yog tus qauv kub rau siab - ntim ntau lawm, tab sis tus nqi siv thiab lub sijhawm ua haujlwm ua rau nws tsis zoo rau kev sim ua haujlwm thaum ntxov. Pure additive manufacturing ua hauj lwm zoo rau cov tswv yim qauv, tsis tau muaj ntau engineers tseem nyiam qhov chaw uas xav tias ze rau qhov kawg molded khoom thaum lawv muab cov cuab yeej rau cov kws kho mob los yog khiav cov kev ntsuam xyuas.

Polyurethane Cast Prototypessau qhov nruab nrab hauv av. Silicone tooling yog pheej yig. Lub sij hawm txhuas feem ntau ntsuas nyob rau hauv hnub ntau dua li lub lis piam. Nto tiav thiab qhov sib xws ntawm qhov sib xws yog siab txaus rau ntau yam kev siv tau thiab tsim kev txheeb xyuas cov haujlwm. Rau cov pab pawg uas xav tau 15-40 feem ntau dua li ntau txhiab, qhov kev sib xyaw ua ke no feem ntau ua rau muaj kev nkag siab ntau dua li kev yuam ua ntej rau cov hlau los yog txhuas pwm.

Biocompatibility & Khoom Khoom

Tsis yog txhua txhua polyurethane haum rau kev siv kho mob. Kev kho mob- qib resins siv hauv lub tshuab nqus tsev casting feem ntau yog xaiv rau cytotoxicity qis thiab tuaj yeem nrog ISO 10993 cov ntaub ntawv xeem uas twb muaj lawm rau cov ntsiab lus kawg xws li cytotoxicity, rhiab heev, thiab khaus. Kev tsim nyog tseem nyob ntawm qhov xwm txheej thiab lub sijhawm ntawm tus neeg mob sib cuag. Daim tawv nqaij -cov vaj tsev sib cuag siv rau lub sijhawm txwv tsis pub muaj qhov xav tau sib txawv dua li cov mucosal ntev ntev -cov khoom tiv thaiv. Cov chaw tsim khoom lag luam tseem muaj lub luag haujlwm rau qhov kev ntsuam xyuas biocompatibility zaum kawg ntawm cov khoom tiav.

Cov khoom muaj xws li:

Hardness xws li soft elastomers (Shore A) mus rau cov ntaub ntawv nruj (Shore D)

Cov qib ntshiab thiab translucent pab tau rau lub qhov rais lossis lub teeb qhia

Tsim nyog tsis kam rau cov tshuaj tua kab mob hauv tsev kho mob thiab cov tshuaj ntxuav

Cov kev xaiv uas zoo dua tuaj yeem tiv thaiv UV los yog kub nruab nrab

Cov yam ntxwv no tso caiUrethane Casting Partslos ua haujlwm ua haujlwm sawv cev-ins rau ntau yam khoom siv sab nraud thaum txhim kho.

Common Medical Use Cases

Pab pawg tsis tu ncua siv lub tshuab nqus tsev- nrum polyurethane rau:

Cov khoom siv vaj tse thiab cov ntaub thaiv npog

Ergonomic kov thiab tuav

Cov khoom sib txuas, clips, thiab cov kua dej yooj yim -txoj kev cuam tshuam

Npog thiab panels rau cov cuab yeej kuaj mob

Cov qauv kev cob qhia rau kev siv kho hniav thiab orthopedic

Mos-kov grips lossis overmolded nta ntawm cov khoom siv tes

Kev muaj peev xwm ua kom haum cov xim, kev ntxhib los mos, thiab kev xav ntawm lub tshuab ua kom pom zoo ua rau cov khoom no muaj txiaj ntsig zoo hauv cov kws kho mob cov lus pom zoo dua li feem ntau yog - cov qauv luam tawm.

Lub siab - tus tswv raug tsim, feem ntau yog SLA lossis CNC.

Liquid silicone is poured around the master under vacuum and cured to form the mold.

Ob-ib feem polyurethane resin yog tov, degassed, thiab cam khwb cia rau hauv pwm nyob rau hauv lub tshuab nqus tsev.

Qhov seem kho, ces yog demolded.

Kev ua haujlwm thib ob-trimming, painting, silk-kev tshuaj ntsuam, EMI txheej, lossis lub teeb sib dhos- tau ua tiav raws li xav tau.

Ib qho pwm silicone yields 20-30 qhov zoo. Cov geometries yooj yim thiab ceev faj cov txheej txheem tswj tau qee zaum thawb qhov siab dua. Hauv kev xyaum, ntau txoj haujlwm kho mob tau txais 20-25 cov qauv ua haujlwm nyob rau hauv kwv yees li ob lub lis piam ntawm kev pom zoo tus tswv. Qhov kev ceev ntawd tseem ceeb thaum qhov kev tshuaj xyuas tus qauv tom ntej lossis tus kws kho mob tau teem sijhawm.

Ib daim ntawv qhia ua haujlwm: aggressive resins lossis complex undercuts luv pwm lub neej. Cov neeg muag khoom uas muaj kev paub dhau los yuav chij qhov no thaum ntxov thiab tuaj yeem pom zoo rau ntau lub pwm yog tias koj qhov ntau nyob ze ntawm qhov kawg ntawm qhov ua tau zoo.

Ib pab neeg tsim cov cuab yeej kuaj mob nqa tau xav tau 28 qhov chaw ua haujlwm rau kev tshuaj xyuas tus kws kho mob thiab kev txheeb xyuas tus qauv tsim sab hauv. Yav dhau los CNC batch tau siv ze li tsib lub lis piam thiab nqa ib qho siab ntawm - tus nqi ib feem . 3D- cov ntawv luam tawm tau muaj sai sai tab sis ua tsis tau raws li qhov zoo ntawm qhov chaw thiab qhov kev cia siab ntawm pawg soj ntsuam.

Lawv tsiv mus rau lub tshuab nqus tsev casting nrog kev kho mob - qib polyurethane. Thawj cov ntawv tuaj txog hauv cuaj hnub ua haujlwm. Tag nrho cov nqi rau cov batch yog kwv yees li 40% qis dua qhov CNC khiav dhau los. Nto tiav thiab xim sib phim cov khoom tsim tawm zoo li zoo txaus uas pab pawg kho mob tau kho cov khoom ua tus sawv cev. Cov ntaub thaiv npog kuj tau dhau qhov kev sim poob sab hauv thiab rov ua tshuaj so-downs yam tsis muaj teeb meem.

Vim tias qhov iteration tau nrawm dua thiab tsis tshua kim, pab pawg tau muab cov lus qhia los ntawm cov kev ntsuam xyuas ua ntej khov cov qauv tsim rau cov cuab yeej nyuaj. Tus neeg muag khoom tau muab cov ntaub ntawv pov thawj thiab ua haujlwm raws li tus neeg tau txais kev cia siab zoo, suav nrog NDA thiab cov kev cai yooj yim traceability.

Rau ntau pab pawg kho mob, qhov kev txiav txim siab tsawg dua ntawm cov txheej txheem twg yog "zoo tshaj" thiab ntau ntxiv txog qhov twg yog qhov sib tw rau theem tam sim no thiab ntau. Thaum koj xav tauUrethane Casting Partsuas saib thiab xav tias ze rau ntau lawm thaum tseem nyob twj ywm saj zawg zog ntawm kev tsim, nqus casting nquag yeej.

Saib tshaj tus nqi thiab lub sijhawm ua khoom. Cov lus nug tseem ceeb muaj xws li:

Lawv puas muaj kev txhawb nqa ISO 13485 ib puag ncig lossis ua haujlwm raws li cov neeg siv khoom zoo?

Lawv puas tuaj yeem muab cov ntaub ntawv pov thawj thiab cov ntaub ntawv pov thawj yooj yim?

Lawv puas kam kos npe rau NDA ntxov?

Puas yog lawv muab cov lus qhia ncaj ncees rau pwm lub neej thiab kev pheej hmoo geometry, lossis lawv puas tsuas hais txog tus lej zoo tshaj plaws?

Lawv ua li cas rau kev tshaj tawm - ua thiab cov ntaub ntawv?

Ib tus neeg muag khoom uas tus chij muaj peev xwm muaj teeb meem nrog undercuts lossis resin aggressiveness ua ntej koj cog lus yog feem ntau muaj nqis tshaj ib qho uas tsuas yog cog lus ceev.

Tso tseg tos lub lis piam rau cov cuab yeej uas yuav xav tau kev kho dua tshiab. Tau txais cov qauv kev kho mob ua haujlwm zoo uas saib thiab xav tias ze dua rau cov khoom tsim khoom- yam tsis muaj lub sijhawm ua haujlwm ntev lossis cov cuab yeej siv siab. Qhia koj cov ntaub ntawv rau DFM tshuaj xyuas thiab nqe lus. Txawm koj xav tauNqus Casting Prototypesrau kev ntsuam xyuas tus kws kho mob lossis kev ua haujlwm luv luvUrethane Casting Partsrau kev txheeb xyuas, cov txheej txheem tsim nyog tuaj yeem khaws ob lub sijhawm thiab kev siv nyiaj hauv kev tswj hwm zoo dua.
