Qee cov kauj ruam tseem ceeb ntawm cov txheej txheem casting nyob rau hauv precision castings!

Precision casting yog ib qho txheej txheem los cuam tshuam hauv cov hlau casting manufacturers, tab sis kev txhim kho tam sim no tsis zoo li cov hlau nrum thiab cov hlau nrum, tab sis kev nrum casting tuaj yeem tau txais cov khoom zoo thiab cov kev ua haujlwm siab precision.

Txoj hauv kev siv ntau dua rau kev nrum casting yog qhov tsim cov khoom pwm raws li kos duab. Qhov sib txawv ntawm precision casting thiab steel casting yog tias cov hlau casting yuav tsum muaj qee yam npoo rau kev ua, thaum lub precision casting tuaj yeem muaj npoo lossis tsis.Qhov thawj cov qauv ciab yog tau los ntawm kev ua casting, thiab tom qab ntawd cov txheej thiab cov xuab zeb txheej txheem rov ua dua. ntawm cov qauv ciab. Tom qab lub plhaub hardened yog qhuav, sab hauv qauv ciab yog yaj. Cov kauj ruam no yog dewaxing, yog li kom tau txais cov kab noj hniav; Tom qab ci lub plhaub, peb tuaj yeem tau txais lub zog txaus thiab huab cua permeability. Tom qab ntawd peb tuaj yeem muab cov kua hlau uas yuav tsum tau ntim rau hauv kab noj hniav. Tom qab txias txias, peb tuaj yeem tshem lub plhaub thiab tshem tawm cov xuab zeb, kom thiaj li tau txais cov khoom lag luam siab tiav.Peb tuaj yeem nqa cov kev kho cua sov lossis ua haujlwm txias raws li qhov xav tau ntawm cov khoom.

Txheej txheem peev txheej peev:

1. Raws li cov kev xav tau ntawm cov neeg siv khoom kos duab, cov pwm raug muab faib rau sab saud thiab qis qis pwm, uas yog ua tiav los ntawm milling, tig, npaj thiab lwm cov txheej txheem. Cov duab ntawm lub pwm qhov yuav tsum muaj ib nrab ntawm cov khoom ib nrab. Vim li cas cov ciab pwm yog siv rau kev lag luam pwm moulding, peb yuav tsum xaiv cov khoom siv aluminium alloy nrog cov tawv hardness, tsis tshua muaj siab, qis tus nqi, lub teeb ceeb thawj thiab qis melting taw tes raws li pwm.

2. Tom qab xaiv cov khoom siv aluminium alloy zoo, peb tuaj yeem siv cov khoom siv aluminium alloy los tsim cov lag luam ntau ntawm cov qauv siv quav ciab.Ua ib qho xwm txheej zoo, cov pwm ntawm kev lag luam siv quav ciab tsuas tuaj yeem tsim cov khoom seem ib.

3. Thaum cov qauv siv quav ciab tau npaj lawm, nws yog qhov yuav tsum tau hloov kho cov npoo ntawm cov qauv ciab. Tom qab tshem cov superfluous yam rau saum npoo, nws yog ib qhov tsim nyog los lo ib qho qauv ciab ntawm lub taub hau npaj.

4. Peb muaj ib tug xov tooj ntawm cov ciab pwm lub taub hau coated nrog cov kua nplaum, thiab tom qab ntawd tusyees txau nrog thawj txheej ntawm hluav taws-kub thiab siab kub tiv thaiv silica xuab zeb.Qhov hom xuab zeb no me me thiab zoo, uas tuaj yeem xyuas kom meej tias kawg npoo ntawm seem yog tus.

5. Tom qab ntawd muab cov qauv ciab rau hauv lub Hoobkas uas peb teeb chav sov rau kev ua kom huab cua qhuav, tab sis nws yuav tsum tsis txhob cuam tshuam cov duab hloov ntawm cov qauv hauv sab hauv. Lub sijhawm ntawm cov huab cua kom qhuav yog nyob ntawm qhov ua haujlwm sab hauv ntawm cov pwm. Feem ntau hais lus, thawj lub sijhawm huab cua kom qhuav yog li 5-8 teev.

6. Thaum cov qauv siv quav ciab yog cua qhuav, ib txheej txheej ntawm kev lag luam kua nplaum xav tau nyob rau saum npoo ntawm cov qauv ciab, thiab ib txheej thib ob ntawm cov xuab zeb tau txau rau saum npoo. Cov xuab zeb hauv txheej txheej thib ob yog qhov loj dua thiab coarser dua li cov uas nyob rau thawj txheej.Tom qab kov cov txheej txheej ntawm cov xuab zeb thib ob, raws li thawj txheej, nqa cov cua kom qhuav.

7. Tom qab txheej txheej thib ob ntawm cov xuab zeb yog qhuav lawm, txheej txheej thib peb, txheej thib plaub thiab txheej tsib ntawm cov xuab zeb blasting yuav tsum tau ua tiav .Sandblasting qhov yuav tsum tau ua: peb yuav tsum kho cov xuab zeb xuab zeb raws li qhov ua tau zoo ntawm cov nplaim thiab ntim ntawm cov khoom.Qhov feem ntau, zaus ntawm sandblasting yuav txog 3-7 zaug.Qhov particle loj ntawm txhua sandblasting yog qhov sib txawv, cov xuab zeb ntawm txhua cov txheej txheem yog coarser dua li dhau los, thiab cov huab cua ziab lub sijhawm kuj sib txawv.Generally, lub sij hawm ntawm sanding on ua tiav ciab qauv yuav hais txog 3-4 hnub.
