Moulded Variuos Silicone Roj Hmab O Nplhaib Sealing

Material Properties thiab Compound Selection

Cov qauv molecular ntawm silicone (polysiloxane) muab kev sib xyaw ua ke ntawm thermal stability thiab qis -kub yooj. Peb cov txheej txheem silicone tebchaw ua haujlwm tsis tu ncua los ntawm -60℃mus rau +220 degree, nrog rau cov qauv tshwj xeeb txuas ntxiv mus dhau qhov no. Qhov no thermal resilience ua rau silicone lub neej ntawd kev xaiv rau daim ntaub ntawv uas muaj high-temperature curing cycles, engine compartments, los yog cryogenic ib puag ncig.

Tshaj li qhov kub thiab txias, silicone muaj kev tiv thaiv zoo rau ozone, UV hluav taws xob, thiab huab cua, ua rau nws haum rau sab nraum zoov thiab ntev - lub neej zoo li qub sealing daim ntaub ntawv. Cov khoom siv no tsis yog- tshuaj lom thiab tsis muaj ntxhiab, tso cai rau peb muab cov khoom sib xyaw ua raws li FDA 21 CFR 177.2600, USP Class VI, thiab NSF/3-A cov qauv kev huv rau zaub mov, dej haus, thiab cov khoom siv kho mob.

Txawm li cas los xij, silicone tsis yog cov khoom siv sib khi thoob ntiaj teb. Nws muaj lub zog nruab nrab ntawm lub zog thiab ua haujlwm tsis zoo rau cov kua qaub, alkalis, thiab roj av-raws li roj. Thaum lub sijhawm hais lus thiab kev tshuaj xyuas engineering, peb ntsuas tus neeg siv khoom cov kev xav tau tshaj tawm kom paub meej tias silicone yog qhov tsim nyog elastomer rau daim ntawv thov. Rau siab -siab lossis roj- qhov chaw raug, peb tuaj yeem pom zoo lwm cov ntaub ntawv xws li FKM lossis HNBR.

Moulded Manufacturing txheej txheem

Moulded silicone O-rings yog tsim los ntawm compression molding los yog hloov molding txheej txheem, xaiv raws li ib feem geometry, ntim yuav tsum tau, thiab qhov ntev kam rau ua. Hauv compression molding, ua ntej- hnyav silicone blanks yog muab tso rau hauv cov pwm kab noj hniav thiab kho nyob rau hauv siab. Cov txheej txheem no yog tus nqi- siv tau rau cov khoom nruab nrab mus rau qhov siab thiab cov qauv ntoo khaub lig- ntu.

Rau qhov uas yuav tsum tau nruj dua flash tswj, complex geometries, los yog ntau dua dimensional repeatability, peb siv kua txhaj molding (LIM). LIM koom nrog kev txhaj tshuaj catalyzed kua silicone ncaj qha rau hauv cov kab noj hniav uas muaj cua sov, uas ua rau muaj qhov flash tsawg, lub sij hawm voj voog sai dua, thiab kev sib raug zoo hauv qhov loj me. Cov txheej txheem no muaj txiaj ntsig tshwj xeeb rau cov me me -inch O-rings, nyias cross-sections, thiab siab- ntim ntau lawm.

Tom qab-moulding, tag nrho O-rings undergo deflashing thiab lwm yam haujlwm raws li qhov yuav tsum tau ua. Cryogenic deflashing yog ua hauj lwm rau siab - ntim txheem qhov chaw kom tshem tawm flash yam tsis ua puas lub sealing nto. Rau kev cai los yog tsawg- ntim qhov chaw, phau ntawv trimming kom meej meej txhais. Kev tshaj tawm kom raug- kho kom zoo yog siv rau txhua qhov silicone O-rings kom ruaj khov ntawm cov khoom, txo cov txheej txheem compression, thiab ua kom zoo ib yam ntev - lub sijhawm ua haujlwm.

Dimensional Control thiab Quality Verification

Sealing kev ua tau zoo yog ncaj qha nyob ntawm qhov raug qhov tseeb. Ib qho O- nplhaib uas sib txawv ntawm qhov tshwj xeeb tuaj yeem ua rau tsis txaus compression, extrusion rau hauv caj pas, lossis ua tsis tiav ntxov. Peb cov txheej txheem tsim khoom suav nrog hauv - txheej txheem kev kuaj xyuas qhov ntev thiab kev tswj xyuas cov txheej txheem txheeb cais (SPC) txhawm rau saib xyuas qhov tsis tseem ceeb suav nrog txoj kab nruab nrab sab hauv, hla -section txoj kab uas hla, thiab concentricity.

Peb tuav cov qauv kev lag luam kam rau ua raws li ISO 3601-3 thiab AS568, nrog rau kev muaj peev xwm tswj tau nruj dua rau cov ntawv thov raug. Thawj tsab xov xwm tshuaj xyuas yog ua rau tag nrho cov cuab yeej tshiab, thiab kev tshuaj xyuas ib ntus txheeb xyuas cov txheej txheem tsis tu ncua. Cov khoom siv xws li durometer, tensile lub zog, elongation ntawm so, thiab compression teeb raug kuaj raws li ASTM cov qauv raws li ib feem ntawm peb cov txheej txheem tso tawm batch.

Customization thiab Engineering Support

Txawm hais tias qhov ntau thiab tsawg tus qauv npog ntau daim ntawv thov, cov tshuab ua haujlwm feem ntau yuav tsum tsis yog -tus qauv O-rings. Peb qhov chaw txhawb nqa kev tsim khoom los ntawm cov qauv los ntawm kev tsim khoom, suav nrog:

Tsis yog -txoj kab uas hla sab hauv thiab hla- ntu kom phim cov caj pas muaj tswv

Kev cai compound formulations rau tej xim coding, conductivity, los yog raws li txoj cai

Tsawg- compression- teeb tsa cov khoom sib txuas rau cov ntawv thov sealing tseem ceeb

Prototype tooling rau tsim validation ua ntej cog lus rau ntau lawm pwm

Peb tshuaj xyuas cov neeg siv khoom kos duab thiab cov qauv tsim qauv los muab DFM (Design for Manufacturability) tawm tswv yim, txheeb xyuas cov teeb meem uas muaj feem cuam tshuam nrog kev sib piv, zawj sau, lossis kev teeb tsa tshem tawm ua ntej kev tsim khoom.

Kev muab khoom thiab cov ntaub ntawv

Raws li tus neeg muag khoom OEM, peb muab cov ntaub ntawv taug qab thiab ua raws li cov ntaub ntawv los txhawb cov kev cai hauv qab. REACH, RoHS, thiab FDA cov lus ua raws cai muaj rau cov qauv sib xyaw, thiab cov qauv kev cai tuaj yeem tsim nyog tau raws li cov qauv kev lag luam tshwj xeeb.

Peb tuav raw cov ntaub ntawv cov khoom lag luam rau cov nquag teev cov ntsiab lus los txhawb kev tsim cov sijhawm ua haujlwm. Rau cov kev pab cuam ntev -, daim pam txiav txim nrog cov sij hawm tso tawm tso cai rau cov neeg siv khoom los tswj cov khoom muag thaum muaj peev xwm tsim khoom.

Pab pawg kws tshaj lij tau txais tos xa cov lus qhia tshwj xeeb, cov qauv, lossis cov ntawv thov tsis raug rau kev ntsuas. Peb muab cov ntaub ntawv thiab cov txheej txheem cov lus pom zoo raws li cov kev ua haujlwm tiag tiag es tsis yog cov khoom muaj nyob hauv phau ntawv, kom ntseeg tau tias cov khoom siv foob ua tau zoo hauv kev sib dhos zaum kawg.
