Stainless hlau hmoov metallurgy

Stainless hlau hmoov metallurgy (PM) yog ib qho cuab yeej siv siab heev uas siv cov hmoov hlau tsis muaj steel hlau los ua cov khoom siv los tsim nyob ze -net-puab qhov chaw los ntawm nias thiab siab - kub sintering. Nws ua ke cov kev tiv thaiv zoo heev ntawm cov hlau tsis muaj steel, tsim kom yooj yim ntawm cov hmoov hlau metallurgy, thiab kev lag luam kev lag luam ntawm loj - nplai ntau lawm, ua rau nws zoo tagnrho rau cov khoom me me - thiab nruab nrab - qhov loj precision qhov chaw.

Stainless hlau hmoov metallurgy

Core txhais

Cov txheej txheem tseem ceeb Flow

Kev npaj hmoov:Dej- atomized hmoov muaj compressibility zoo, thaum roj- cov hmoov atomized muaj fluidity zoo thiab haum rau MIM. Cov hmoov uas muaj xws li 316L, 304L, thiab 430, tov nrog lubricants xws li lithium stearate.

Kev tsim:Pwm nias (400-800 MPa, rau lub zog, thiab lwm yam) los yog MIM rau qhov nyuaj thiab zoo.

Sintering:1100-1350℃nyob rau hauv kev tiv thaiv huab cua (xws li, siab- purity hydrogen), tuav rau 20-60 feeb, ua tiav 85-95% ntawm theoretical ntom ntom.

Tom qab-kev kho mob:Kev ua tiav, cov phiaj xwm kev kho cua sov (xws li, 17-4PH kev daws teeb meem kev laus), passivation lossis chav kho mob, thiab lwm yam.

Core Zoo

Khaws cov kev ua tau zoo ntawm stainless hlau txawm nyob rau hauv cov duab complex, txo tus nqi siab ntawm kev ua ib txwm ua.

Ua ke corrosion kuj nrog controllable porosity, tso cai rau lub chaw tsim khoom ntawm lim ntsiab nrog kev ua tau zoo dua tom qab chav kho.

Kev ua tau zoo ntawm kev lag luam hauv loj - nplai ntau lawm, nrog cov nqi qis dua li kev siv tshuab lossis casting.

Cov ntawv thov tseem ceeb

Automotive:Roj twj tso kua mis iav, EGR valve qhov chaw, thiab lwm yam.

Kev kho mob thiab zaub mov kev lag luam:Cov cuab yeej siv phais, cov twj ua zaub mov thiab cov li qub, thiab lwm yam.

Cov Khoom Siv Hauv Tsev thiab Cov Khoom Siv Hauv Tsev:Faucet valve cores, thiab lwm yam.

Industrial Hydraulic:Iav twj tso kua mis sab phaj, thiab lwm yam.

Cov Khoom Siv Khoom Siv Khoom Siv:Watch case, thiab lwm yam.

Cov lus nug nquag

Q1: Yuav ua li cas yog qhov corrosion kuj ntawm stainless hlau hmoov metallurgy qhov chaw? Nws puas tuaj yeem ncav cuag qib cam khwb cia lossis forged 304/316?

A: High-density (>93%) thiab zoo- cov ntaub ntawv sintered yog sib piv . 316L qhov chaw muaj tshuaj tsuag ntsev thiab kua qaub/alkali corrosion kuj zoo ib yam li forged qib. Porosity yog qhov tseem ceeb, thiab kev ua kom zoo tuaj yeem ua tau raws li kev lag luam feem ntau.

Q2: Vim li cas PM thiaj suav tias yog "tus nqi tua neeg" rau qhov nyuaj stainless hlau qhov chaw?

A: PM tsim cov khoom pov tseg tsawg dua thiab txo cov nqi zog vim yog ib qho -pab molding, nrog cov nqi pwm kis ntau ntau lawm. Hauv qhov sib piv, CNC machining tuaj yeem pov tseg ntau dua 70% ntawm cov khoom siv thiab ua rau cov nqi zog siab. Qhov ntau qhov nyuaj, qhov tseem ceeb tshaj qhov zoo ntawm PM.

Q3: Dab tsi yog qhov txawv ntawm stainless hlau MIM thiab tsoos PM molding?

A: Traditional PM is suitable for regular shapes, parts weighing a few grams to several hundred grams, and wall thickness >1 hli, nrog cov cuab yeej siv qis. MIM yog qhov tsim nyog rau qhov nyuaj heev, zoo qhov hnyav<100 g, offering high design freedom but requiring expensive molds.

Q4: Dab tsi yog cov txheej txheem thiab ncua sij hawm los ntawm kev kos duab rau pawg- cov qauv tsim khoom rau qhov tshiab?

A: DFM tsom xam thiab hais lus (1-2 lub lis piam) → Pwm tsim thiab tsim khoom (4-6 lub lis piam) → Qauv sim thiab kuaj (2-3 lub lis piam) → Pwm hloov thiab pom zoo (1-2 lub lis piam) → me- batch sim ntau lawm (1-2 lub lis piam), tag nrho 9-15 lub lis piam. Cov txheej txheem MIM muaj lub voj voog ntev dua.
