Rau ib qho twgkhoom siv kho mob,zoo yog lub neej. Rau cov khoom siv pov tseg pov tseg, uas ncaj qha nkag mus rau cov ntaub so ntswg tsis huv ntawm tib neeg lub cev thiab tseem ceeb heev rau kev ua tiav lossis tsis ua tiav ntawm kev phais, kev tswj kom zoo yuav tsum tau ua kom tiav. Tau txais ntawv pov thawj xws li ISO 13485 thiab ISO 9001 tsuas yog "daim pib nkag mus." Qhov kev tiv thaiv zoo tiag tiag yog tsim los ntawm "zero- tsis raug" kev tswj xyuas zoo uas cuam tshuam tag nrho cov txheej txheem los ntawm kev tsim, cov khoom siv raw, kev tsim khoom mus rau kev ua kom tsis muaj menyuam, thiab deb tshaj qhov yuav tsum tau ua.

I. Tsim thiab tswj kev nkag: Zoo tau txais los ntawm Tsim (QbD)

Qhov zoo yog thawj "sib koom" rau hauv cov khoom thaum lub sij hawm tsim txheej txheem. Cov chaw tsim tshuaj paus kev tswj hwm zoo pib nrog nruj "tsim tswj." Qhov no suav nrog - hloov pauv qhov tob ntawm cov kev cai kho mob (xws li cov kev xav tau rau kev sib tsoo quab yuam, kev ua haujlwm sib khi, thiab pob tshab rau cov kev phais sib txawv), kev xaiv cov khoom siv science (xws li cov nplej loj ntawm cov hlau tsis muaj steel, lub teeb xa tawm thiab biocompatibility ntawm cov ntaub ntawv polymer), thiab tom ntej - saib cov ntsiab lus ntawm qhov kev pheej hmoo ntawm txhua qhov kev pheej hmoo. ntawm lub sealing valve, thiab muaj cov khib nyiab hauv lub raj) los ntawm kev ua haujlwm tsis ua haujlwm thiab kev tsom xam cov txiaj ntsig (FMEA), thiab tsim cov kev tiv thaiv kev tiv thaiv ntawm theem tsim. Piv txwv li, txhawm rau txo qhov kev pheej hmoo ntawm cov khib nyiab, tus qauv tsim yuav tsum tsis txhob tsim kev nyuaj -kom- ntxuav cov ces kaum tuag thiab qhia txog kev siv cov kav dej seamless steel lossis cov txheej txheem vuam tshwj xeeb.

II. Cov khoom nkag thiab cov txheej txheem tswj: cuam tshuam qhov tsis xws luag ntawm txhua theem

Qhov no yog qhov tseem ceeb ntawm kev tswj xyuas qhov zoo. Ua raws li qib siab - txheej txheem tsim khoom kawg tau piav qhia hauv cov ntawv ua piv txwv, nws cov txheej txheem tswj tau raug siv los ntawm txhua qhov chaw ua haujlwm:

Kev tshuaj xyuas cov khoom xa tuaj: Rau txhua pawg ntawm cov kav hlau stainless, tsis yog tsuas yog tshawb xyuas cov ntaub ntawv qhia, tab sis kuj tseem raug tshuaj xyuas cov phab ntsa sab hauv, cov tshuaj muaj pes tsawg leeg, thiab cov khoom siv kho tshuab raug tshuaj xyuas. Rau cov khoom yas, cov khoom siv yaj, cov ntsiab lus impurity, thiab daim ntawv pov thawj biocompatibility raug kuaj.

Kev saib xyuas cov txheej txheem hauv online: Hauv cov txheej txheem machining precision, kev ruaj ntseg ntawm cov khoom siv (xws li Citizen tshuab cuab yeej) yog qhov tseem ceeb. Txawm li cas los xij, cov tuam txhab siab - kawg yuav siv cov txheej txheem kev tswj hwm (SPC) los saib xyuas qhov sib txawv ntawm cov kev hloov pauv hauv qhov loj me (xws li sab hauv thiab sab nraud ntawm lub tes tsho, thiab qhov chaw nyob) hauv lub sijhawm. Thaum muaj ib lub cim ntawm kev sib txawv ntawm cov kab tswj, cov txheej txheem yuav raug kho tam sim ntawd es tsis txhob tos kom tiav cov batch rau kev soj ntsuam. Kev deburring online tam sim ntawd tom qab ua tiav nws tus kheej yog qhov tseem ceeb ntawm kev tiv thaiv kev ua yuam kev.

Cov txheej txheem tshwj xeeb kev lees paub thiab kev lees paub: Rau "cov txheej txheem tshwj xeeb" uas nws cov txiaj ntsig tsis tuaj yeem tshawb xyuas tag nrho los ntawm kev tshuaj xyuas tom ntej, xws li electrolytic polishing, ultrasonic tu, thiab txhaj tshuaj molding, nruj txheej txheem parameter pov thawj yuav tsum tau nqa tawm. Piv txwv li, nws tau lees paub tias qhov tam sim no voltage thiab lub sijhawm ua ke tuaj yeem ua tiav qhov zoo tshaj plaws polishing nyhuv; qhov zaus, lub sij hawm, thiab ntxuav cov kua mis ntawm ultrasonic tu yog xyuas kom meej 100% tshem tawm ntawm tej yam - me me hais.

High-frequency, multi-dimensional interim inspection: Qhov no tsis yog ib qho yooj yim sampling soj ntsuam, tab sis ze li ntawm 100% kev tshuaj ntsuam thiab ntau interlocking soj ntsuam. Ua ntej lub tes tsho yuav dhau los ua cov khoom tiav, nws yuav raug kuaj xyuas tag nrho tom qab ua tiav (calipers, nres- cov neeg kuaj xyuas), random tshuaj xyuas ntawm lub ntsej muag gloss tom qab electrolytic polishing, endoscopy tshuaj xyuas cov yeeb nkab sab hauv kom huv tom qab ntxuav ultrasonic, thiab huab cua nruj tom qab sib dhos nrog cov khoom yas. Qhov "ntau tshaj 6 qhov kev tshuaj xyuas" tau hais hauv cov ntawv nyeem yog ib qho piv txwv ntawm qhov kev tshuaj xyuas zoo.

III. Kev Tshaj Tawm Kawg thiab Traceability: Kev lees paub ntawm cov ntaub ntawv

Tom qab tag nrho cov khoom tau raug ntxuav lawm, lawv yuav tau txais kev sib dhos zaum kawg hauv Chav Kawm 10,000 chav huv. Cov khoom tiav lawm yuav tau mus rau qhov nruj tshaj plaws "kev xeem kawm tiav":

Kev sim ua haujlwm: Simulate kev siv tiag tiag thiab kev ntsuas lub zog, kev sib khi ua haujlwm (nyob rau hauv cov huab cua sib txawv thiab cov cuab yeej sib cuam tshuam), valve qhib thiab kaw yooj, thiab kev sib txuas lub zog ntawm txhua yam, thiab lwm yam.

Kev ntim khoom thiab kev ua kom tsis muaj menyuam: Cov khoom ntim yuav tsum ua kom tsis muaj kab mob tom qab ua kom tsis muaj menyuam. Cov txheej txheem ua kom tsis muaj menyuam (feem ntau yog ethylene oxide lossis irradiation) yuav tsum tau kuaj xyuas nruj kom ntseeg tau tias kev nkag mus ntawm tus neeg ua haujlwm tsis muaj menyuam thiab qib kev ua kom tsis muaj menyuam (SAL) ntawm 10^-6.

Tag nrho lub neej voj voog traceability: Txhua batch thiab txawm tias txhua yam khoom yuav tsum muaj tus cim tshwj xeeb, uas tuaj yeem taug qab mus rau batch tus naj npawb ntawm cov khoom siv raw siv, pab pawg tsim khoom, cov txheej txheem tseem ceeb, cov tshuaj ntsuam xyuas, thiab kev ua kom tsis muaj menyuam. Nyob rau hauv qhov xwm txheej ntawm qhov tshwm sim tsis tshua muaj tshwm sim, nws yuav tsum muaj peev xwm txheeb xyuas qhov tseeb thiab rov qab los ntawm lub sijhawm luv tshaj plaws.

IV. Cultural Beyond the Norm: Zero Tolerance for the "abnormal"

Kev tswj hwm qib siab tshaj plaws yog qhov "zero- tsis zoo" lub siab xav ua ke rau hauv kev coj noj coj ua ntawm cov tuam txhab. Qhov no yog manifested nyob rau hauv lub keenness thiab persistence nyob rau hauv kev kuaj xyuas tej yam me me txawv txav. Piv txwv li, thaum lub sij hawm soj ntsuam zaum kawg, txawm tias ib tug me ntsis khawb nyob rau hauv tus txheej txheem kam rau ua ntau yam, yog hais tias nws yog pom tau hais tias muaj feem xyuam rau cov kev xav los yog kev xav ntawm tus neeg mob, tej zaum yuav raug txiav txim raws li tsis yog -raws li. Kev ntshai ntawm cov khib nyiab hauv cov hlab ntsha ua rau qhov xav tau tsis yog tsuas yog tso siab rau cov khoom siv tu ultrasonic nkaus xwb tab sis kuj ntxiv cov khoom kim heev tab sis txhim khu kev qha kev siv tshuaj ntsuam xyuas rov- tshuaj xyuas. Qhov "kev xav tsis txaus ntseeg" thiab "ntau yam kev tiv thaiv" kev xav yog qhov kawg thiab muaj zog tshaj plaws ntawm kev tiv thaiv rau cov khoom lag luam ntseeg tau.

Yog li ntawd, cov txheej txheem ntawm kev nyab xeeb thiab txhim khu kev qha cov khoom siv pov tseg los nrog kev ua kom muaj zog thiab nruj tag nrho - txheej txheem kev tswj hwm kev tswj hwm zoo uas sib koom ua ke cov cuab yeej tsim khoom siab tshaj, cov txheej txheem kev tswj hwm kev tshawb fawb, thiab kab lis kev cai zoo kawg nkaus. Nws sib txuas lus rau kev lag luam tias kev nyab xeeb thiab kev ua tau zoo yog sau rau hauv txhua qhov kev nthuav dav ntawm txhua tus txheej txheem thiab hauv txhua qhov piv txwv ntawm cov qauv dhau los ntawm tus kheej - cov kev cai.
