Isostatic graphite blocks yog tsim los siv cov txheej txheem txias isostatic pressing (CIP) uas siv cov hydraulic siab los ntawm tag nrho cov lus qhia rau cov pa roj carbon feedstock. This production method eliminates the density gradients and structural anisotropy typical of conventional extruded or molded graphite, yielding high structural homogeneity, isotropic mechanical strength, and fine microstructures.
Cov khoom muaj qib muaj xws li zoo -grain general engineering specifications mus rau siab - ntom, ultra- ntshiab variants tailored rau rhiab siab - kub thiab siab -precision ib puag ncig.

Daim ntawv thov -Kev xaiv qib tshwj xeeb
EDM Electrodes & Precision Tooling:Lub zog flexural siab, nplua nplej loj, thiab cov hluav taws xob tsis tshua muaj hluav taws xob ua kom cov khoom siv hluav taws xob tsawg tsawg, cov khoom siv siab tshem tawm, thiab cov khoom zoo tshaj plaws ua tiav ntawm cov geometries thiab nqaim tav.
Nqus Furnaces & Hot Zones:Xaiv rau cov khoom cua sov, rwb thaiv tsev thaiv, thiab cov qauv kev txhawb nqa. Kev ntsuam xyuas yuav tsum suav rau qhov ntsuas kub siab tshaj plaws, kev ua haujlwm huab cua (nqus lossis inert gas), thiab thermal poob siab.
Semiconductor & Crystal Loj hlob:Cov qib siab -purity qib (BTD-20/22) muaj cov hmoov tshauv nruj thiab cov kaus mom hlau. Nws yog ib qho tseem ceeb rau cov khoom rhiab rau metallic paug nyob rau hauv silicon crystal rub los yog epitaxial systems.
Kub Pressing & Sintering Tuag:Siab compressive zog thiab seem stability nyob rau hauv load ntawm siab kub rau hmoov metallurgy thiab advanced ceramic tooling.
Machining & Tolerance Guidelines
Kev yuav cov graphite nyoos blocks yuav tsum tau sau nyiaj rau kev tshaj tawm - sawing machining thiab ua tiav cov haujlwm.
Saw-Cut Blanks vs. Precision Sawn:Standard blocks yog muab nrog saws - txiav los yog npaj nto. Ib txwm ntxiv qhov tsawg kawg nkaus machining nyiaj pub dawb (feem ntau 1 hli mus rau 3 hli ib sab nyob ntawm qhov ntsuas qhov ntsuas) txhawm rau ntxuav cov cuab yeej cim thiab ua tiav qhov kev kos duab kawg.
Isotropic Stability:Vim tias isostatic graphite nthuav tawm cov thermal thiab mechanical zog nyob rau hauv tag nrho cov lus qhia, distortion thaum lub sij hawm siab -ceev CNC milling los yog sib sib zog nqus- qhov EDMing yog ho txo qis piv rau extruded lwm txoj.
Plua plav & tuav:Isostatic graphite tsim cov plua plav zoo thaum lub sijhawm ua haujlwm. Xyuas kom tsim nyog cov dej lim dej thiab cov plua plav tshem tawm cov txheej txheem raug tsim nyob rau hauv koj lub khw muag khoom.
Quality Assurance & Material Traceability
Rau kev tswj hwm kev lag luam kev lag luam, txhais koj cov ntaub ntawv xav tau pob ua ntej xaj xaj:
Material Test Reports (MTR)
Batch-Kev txheeb xyuas tshwj xeeb ntawm qhov ntom ntom, lub zog flexural, thiab hluav taws xob tiv taus.

Cov lus nug nquag
Q: Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm isostatic nias tshaj cov tshuaj molding?
A: Isostatic nias siv lub siab sib npaug los ntawm txhua qhov kev qhia, tshem tawm qhov sib txawv ntawm qhov sib txawv thiab kev taw qhia anisotropy. Qhov no ua rau muaj zog mechanical superior thiab kwv yees machinability.
Q: Cov blocks nyoos puas tuaj yeem txiav mus rau qhov loj me los txo cov khib nyiab?
A: Yog. Blocks tuaj yeem pom- txiav los ze zog rau koj cov khoom tiav qhov ntev raws li kev kos duab engineering, txo cov khoom siv raw khoom pov tseg thiab hnyav hnyav- lub sijhawm milling.
Q: Yuav ua li cas cov hmoov tshauv txwv cov ntsiab lus tseeb rau qib siab -purity?
A: High- qib purity tau txais cov txheej txheem purification tshwj xeeb. Cov kab hlau tsis huv thiab cov hmoov tshauv tau raug txheeb xyuas los ntawm kev tshuaj xyuas cov ntaub ntawv raws li kev pom zoo.
