Dab tsi yog qee yam khoom siv pwm rau pwm mus tas li?

1, Cov khoom siv hlau
Cov ntaub ntawv hlau yog ib qho ntawm feem ntau siv pwm cov ntaub ntawv nyob rau hauv tas mus li casting, nrog siab hardness, zoo kub kuj, thiab siab zog, uas yuav ua tau raws li cov kev xav tau ntawm feem ntau casting txheej txheem.
Txias ua hauj lwm pwm steel: Nws muaj zoo hnav tsis kam thiab toughness, thiab yog haum rau manufacturing pwm nrog complex duab thiab siab precision yuav tsum tau. Cov ntaub ntawv xws li Cr12MoV thiab Cr12, tom qab kev kho cua sov, muaj qhov tawv ntawm ntau dua 60HRC thiab txhim kho kev hnav tsis kam, tab sis lawv cov tawv tawv tau txo qis. Yog li ntawd, nws yog ib qho tsim nyog los tswj cov txheej txheem kev kho cua sov kom tsim nyog.
Kub ua hauj lwm tuag steel: feem ntau yog siv rau kev tsim pwm uas ua hauj lwm kub, xws li tuag-casting pwm, kub forging tuag, thiab lwm yam. Cov khoom no muaj zoo thermal stability thiab thermal qaug zog, xws li 5CrNiMo, 5CrMnMo, thiab lwm yam. , uas muaj peev xwm tswj tau siab hardness thiab lub zog ntawm qhov kub thiab txias, txo thermal deformation thiab tawg ntawm pwm.
Hard alloy steel: Nws yog cov khoom siv pwm ua haujlwm siab nrog cov yam ntxwv xws li siab hardness, siab zog, siab hnav tsis kam, thiab siab corrosion kuj. Haum rau kev tsim high-precision, siab load pwm, xws li precision stamping tuag, sib sib zog nqus nqus tuag, thiab lwm yam. Txawm li cas los, nyuaj alloy steel yog kim thiab nyuaj rau txheej txheem, yuav tsum nruj tswj kev ua thiab kev kho cua sov txheej txheem.
2, Cov khoom siv hlau
Cov ntaub ntawv hlau cam khwb cia ua lub luag haujlwm tseem ceeb hauv kev tsim pwm tas mus li vim lawv zoo heev hnav tsis kam, corrosion kuj, thiab kub tsis kam.
Grey cam khwb cia hlau: Nws muaj zoo casting thiab mechanical zog, tsis tshua muaj nqi, thiab yog haum rau tsim loj thiab structurally yooj yim pwm. Txawm li cas los xij, lub hardness thiab lub zog ntawm grey cam khwb cia hlau yog qhov tsawg, ua rau nws tsis haum rau high-precision thiab siab load pwm.
Ductile hlau: Los ntawm kev kho spheroidization, cov graphite hauv cam khwb cia hlau tau muab faib ua cov duab kheej kheej, txhim kho lub zog thiab toughness ntawm cam khwb cia hlau. Cov khoom siv hlau pwm muaj qhov hnyav thiab hnav tsis kam, ua rau lawv tsim nyog rau kev tsim pwm nrog nruab nrab load thiab nruab nrab precision, xws li tuag-casting pwm, txhaj tshuaj pwm, thiab lwm yam.
Creep graphite cam khwb cia hlau: Lub graphite morphology ntawm creep graphite cam khwb cia hlau yog nruab nrab ntawm grey cam khwb cia hlau thiab ductile hlau, thiab nws muaj zog zoo heev, toughness, thiab hnav tsis kam. Creep graphite cam khwb cia hlau pwm yog tsim rau kev tsim high-precision, siab load pwm, xws li cav cylinder blocks, lub tog raj kheej taub hau, thiab lwm yam.
3, Aluminium alloy khoom
Aluminium alloy moulds tau siv dav hauv kev tsim cov khoom me me thiab nyuaj vim lawv qhov zoo ntawm lub teeb yuag, siab qhov tseeb, thiab kev ua haujlwm zoo.
Casting aluminium alloys xws li A356, A380, thiab lwm yam. muaj zoo casting thiab txhua yam khoom, haum rau tsim me me thiab structurally complex pwm. Txawm li cas los xij, lub hardness thiab hnav tsis kam ntawm aluminium alloys kuj tsawg, thiab lawv cov hnav tsis kam yuav tsum tau txhim kho los ntawm kev kho cua sov los yog cov txheej txheem kho saum npoo.
Forged aluminium alloys, xws li 2024, 7075, thiab lwm yam., muaj lub zog siab thiab hardness, thiab tsim nyog rau kev tsim pwm nrog nruab nrab load thiab nruab nrab precision. Txawm li cas los xij, tus nqi ntawm forging aluminium alloy yog siab thiab kev ua haujlwm nyuaj yog siab, yuav tsum muaj kev tswj xyuas nruj ntawm kev ua thiab kev kho cua sov.
4, Lwm yam khoom siv
Ntxiv nrog rau cov khoom siv pwm uas tau hais los saum no, kuj tseem muaj qee cov ntaub ntawv tshwj xeeb uas tau siv rau hauv cov pwm mus tas li.
Zinc raws li alloys, xws li ZA12, ZA27, thiab lwm yam., muaj zog zoo thiab hardness thaum tuav ib tug tej yam degree ntawm ductility. Zinc-based alloy pwm yog tsim rau kev tsim cov khoom siv kho tshuab uas tuaj yeem tiv taus cov khoom hnyav, xws li cov kabmob, lub zog, thiab lwm yam. Txawm li cas los xij, qhov corrosion kuj ntawm zinc raws li alloys tsis zoo thiab yuav tsum tau txhim kho los ntawm kev kho deg.
Cov khoom siv ceramic: muaj qhov tawv tawv, hnav tsis kam, siab corrosion kuj, thiab kub tsis kam. Ceramic pwm yog tsim rau kev tsim pwm siv nyob rau hauv qhov kub thiab txias, xws li ceramic txhaj pwm, ceramic tuag-casting pwm, thiab lwm yam. Txawm li cas los xij, qhov brittleness, kev ua haujlwm nyuaj, thiab cov nqi siab ntawm cov khoom siv ceramic txwv lawv cov ntawv thov dav.
