Mould Material Classification
Txhawm rau kom ua tau zoo thiab ua haujlwm ntev ntawm cov pwm yas, xaiv cov khoom tsim nyog yog qhov tseem ceeb. Raws li kev txiav txim siab ntawm cov pwm tsim thiab kev siv cov khoom, cov khoom siv, thiab lwm yam, peb yuav tsum ua tib zoo soj ntsuam ntau yam tseem ceeb xws li hom yas, ntim ntau lawm, thiab qhov tseeb ntawm qhov ntev. Rau ntau qhov ntau thiab tsawg, ntau yam, thiab qhov yuav tsum tau ua ntawm cov khoom yas, cov khoom xaiv rau cov pwm pwm tuaj yeem ua tiav raws li hauv qab no:
General -Lub Hom Phiaj Pwm Cov Khoom Siv
Cov ntaub ntawv no tsuas yog siv los tsim pwm rau polyethylene, polypropylene, thiab lwm yam yas. Rau cov ntim ntau lawm, siab precision yuav tsum, complex duab, los yog loj loj, alloy pwm steels xws li 20CrMnMo thiab 12CrNi4 yog nyiam. Rau cov pwm uas muaj cov ntim me me, tsis muaj qhov tshwj xeeb rau qhov roughness ntawm qhov chaw thiab qhov tseeb qhov tseeb, thiab cov ntoo khaub lig me me -sectional qhov ntev, 45 steel feem ntau siv. Yog hais tias qhov siab qhov tseeb thiab qhov yuav tsum tau muaj qhov roughness, alloy pwm steels uas tau dhau los ntawm electroslag remelting lossis nqus electrostatic electrode remelting, xws li 3Cr2Mo thiab 4Cr5MoSiV1, tej zaum yuav raug xaiv.
Pwm Cov Khoom Siv rau Corrosive Plastics
Thaum molding corrosive plastics xws li polyvinyl chloride (PVC), fluoroplastics, los yog nplaim taws -cov yas retardant, cov pwm yuav tuaj rau hauv cov xov xwm corrosive. Yog li ntawd, nws yog ib qho tsim nyog yuav tau xaiv cov yas pwm steels uas zoo heev corrosion kuj, xws li Cr18MoV, 18Ni, 9Cr18, 4Cr13, Cr14Mo4V, 1Cr17Ni2, PCR, thiab AFC-77.
Pwm Cov Khoom Siv Rau Cov Plastics Reinforced
Thaum tsim cov pwm txhaj tshuaj rau cov yas yas lossis cov pwm extrusion rau cov thermosetting yas, cov pwm ua haujlwm txias tau pom zoo los txhim kho qhov hnav tsis kam ntawm pwm kab noj hniav. Cov hlau no suav nrog Cr12MoV, Cr12Mo1V1, 9Mn2V, Cr6WV, Cr12, 7CrMn2WMo, 7CrMnNiMo, Cr2Mn2SiWMoV, CrWMn, MnCrWV, thiab GCr15. Rau kev txhim kho pwm hnav tsis kam, ua haujlwm txias pwm hlau xws li Cr12MoV raug pom zoo.
Pwm cov khoom siv rau cov khoom siv pob tshab
Rau cov pwm siv hauv kev tsim cov khoom yas pob tshab, muaj hnub nyoog- cov hlau tawv tawv nrog cov iav polishing zoo heev thiab hnav tsis kam yog pom zoo, xws li 18Ni, 06Ni, PMS, PCR, thiab SM2 steels. Cov hlau zoo li 18Ni thiab PMS, uas sib xyaw ua haujlwm polishing nrog hnav tsis kam, tshwj xeeb tshaj yog haum. Tsis tas li ntawd, ua ntej-cov pwm steels xws li SM1, Y82, thiab P20 series, nrog rau 8CrMn, 5NiSCr, thiab cua-txias 12 steel, kuj yog cov kev xaiv zoo.
