MIM (hlau txhaj tshuaj molding) txheej txheem, uas yog ib yam tshiab ntawm cov hlau ib feem ua txheej txheem combining niaj hnub yas txhaj molding txheej txheem thiabhmoov hlau txheej txheem. Cov txheej txheem tshiab no tau tshwm sim thaum xyoo 1970s thiab yog thawj zaug siv los tsim cov khoom siv riam phom. Lub sijhawm no kuv yuav qhia ntau yamMIM hlau txhaj tshuaj molding qhov chawrau riam phom.
JIEHUANG CHIYANG Sab saum toj hlau txhaj tshuaj molding tuam txhab:
Thawj MIM qhov chaw: Electronic ntim MIM qhov chaw. Qhov no yog tsim los ntawmMIM (Hlau Txhaj Moulding) technologythiab tsim los ntawm F15 qib Cheebtsam (Ni-Co-Fe); qhov kam rau ntawm lub qhov yog ntxiv los yog rho tawm 0.2mm. Qhov no hlau txhaj molding khoom yog siv rau Opto-electronic ntim. Ib qho ntawm cov kev xav tau yog qhov nthuav dav ntawm cov khoom siv yuav tsum zoo ib yam li cov iav kaw.
Cov neeg siv khoom tsom mus rau kev sim kev sib khi ua haujlwm ntawm MIM hluav taws xob enclosure tom qab cov khoom raug thermal shock. Qhov no hloov cov khoom tsim los ntawm kev txiav thiab brazing. MIM cov khoom tuaj yeem txo cov nqi tsim khoom ntau dua li cov khoom tsim los ntawm kev txiav.
SECOND MIM qhov chaw: Qhov ntev ntev ntawm kev txhaj tshuaj molding tshuab stainless hlau qhov chaw ntawm cov phom ntev tom qab qhov muag pom kev yog 0.5%. Cov khoom siv tshuaj siv yog thermoplastic binder thiab hlau-7% nickel alloy. Qhov ceev ntawm sintered lub cev ncav cuag 7.82 ib square centimeter. Cov khoom siv kho tshuab tau teev tseg hauv cov txheej txheem yog: tensile lub zog 430MPa, yield zog 295MPa, hardness 55HRC (tom qab carburizing thiab quenching), thiab modulus elasticity 203GPa.
Qhov no manufactured los ntawm lub mim hlau txhaj tshuaj molding txheej txheemyav dhau los ua los ntawm kev txiav. Nyob rau hauv qhov kev pom ntawm cov duab nyuaj ntawm ib feem thiab lub qhov nyob rau hauv cov lus qhia sib txawv, txiav yog kim. Cov cuab yeej pom kev hmo ntuj yog siv rau M-6 phom. Vim yog siv cov txheej txheem MIM, tus nqi ntawm cov khoom tuaj yeem raug txo los ntawm 60%. Tsuas yog carburizing thiab quenching, tsis tas yuav tsum tau kho deg.
