Kev tshuaj ntsuam xyuas:X-ray, CT, metallography, lossis lwm txoj kev NDT?
Mechanical validation:Dab tsi shear- txoj kev sim thiab cov neeg siv khoom- tshwj xeeb kev lees txais yog siv?
Dimensional tswj:Dab tsi CTQ qhov ntev yog saib xyuas los ntawm CMM/SPC?
Automotive zoo:Tus neeg muag khoom puas tuaj yeem muab IATF 16949-raws li cov ntaub ntawv txheej txheem thiab PPAP Theem 3 xa qhov twg xav tau?

 

Cov khoom muaj zog tshaj plaws kev tsim nyog pob txuas cov khoom siv ntau → txheej txheem tsis → tshuaj ntsuam xyuas → tiav -ib ntus lossis batch tooj.

 

 

Rau kev sib txuas ntawm cov nyiaj brazed, AgWC lossis AgC txiav txim siab ntau ntawm arc - tus cwj pwm yaig, tab sis lub brazed interface txiav txim siab seb cov khoom sib txuas puas tuaj yeem hloov hluav taws xob thiab cov khoom thauj mus rau hauv cov khoom siv tooj liab.

 

Kev tsim khoom-npaj npaj yog li ntawd yuav tsum tau tswj kev sib cuag- cov ntaub ntawv muaj pes tsawg leeg, C1100/C2680 tus cab kuj muaj zog, brazing kub, sib koom ua ke clearance, deg npaj, seem raug, NDT, shear testing, thiab batch traceability. Rau cov kev pab cuam tsheb, cov kev tswj xyuas no yuav tsum tau muab tso rau hauv PFMEA, Tswj Kev Npaj, thiab PPAP cov ntaub ntawv ua ntej SOP.

 

Rau cov chaw tsim khoom siv hluav taws xob hluav taws xob hluav taws xob tiv thaiv nyiaj, tus neeg muag khoom tsim nyog tuaj yeem ua kom pom kev sib txuas ntawm cov hlau thiab ntsuas cov txheej txheem muaj peev xwm - tsis yog tsuas yog muab kev sib cuag - daim ntawv pov thawj cov ntaub ntawv taub hau.

 

 

PPAP Theem 3 yuav siv sijhawm ntev npaum li cas rau abrazed silver contact los ua ke?

PPAP lub sij hawm nyob ntawm cov cuab yeej, cov khoom tsim nyog, kev siv tau zoo, thiab cov neeg siv khoom xav tau. Ib txoj haujlwm raug cai yuav tsum txheeb xyuas cov rooj vag sib txawv rau T1 cov qauv, kev pom zoo ntawm qhov ntev, kev siv tau zoo, thiab kev xa PPAP es tsis siv lub sijhawm xa khoom tsis tsim nyog.

 

Cov cuab yeej lub neej dab tsi tuaj yeem xav tau los ntawm qhov tseeb stamping tuag rau cov khoom siv hluav taws xob tiv thaiv hluav taws xob?

Cov cuab yeej lub neej nyob ntawm qib tooj liab, thickness, tuag steel, clearance, stroke rate, thiab tu. Tus neeg muag khoom yuav tsum muab cov cuab yeej- lub hom phiaj lub neej ua ke nrog cov ntaub ntawv mob stroke, tiv thaiv- lub sijhawm tu, thiab cov ntaub ntawv tseem ceeb - qhov ntev SPC.

 

Yuav ua li cas brazed sib koom ua tau zoo kuaj rau AgWC lossis AgC Circuit Court breaker hu?

Kev sib koom ua tau zoo tuaj yeem raug soj ntsuam los ntawm kev tshuaj xyuas qhov muag, X-ray lossis CT rau kev cuam tshuam sab hauv, metallographic cross-section analysis, thiab shear testing. Cov txheej txheem lees txais yuav tsum qhia meej qhov tsis muaj qhov tso cai, thaj chaw sib koom ua ke, qhov txwv qhov ntev, thiab lub zog yam tsawg kawg nkaus.
