Precision Txhaj Moulding Txheej Txheem Tag Nrho -Cov Txheej Txheem Kev Qhia Tshwj Xeeb: Txoj Kev Lean Mus Rau Micron-Level Manufacturing

Hauv kev tsim khoom niaj hnub no, kev txhaj tshuaj molding precision, nrog nws cov kev ua haujlwm siab thiab qhov tseeb, tau dhau los ua cov thev naus laus zis hauv siab -kawg teb xws li electronics, automotive, thiab kev kho mob. Tsim kom muaj kev qhia tshwj xeeb yog ib qho tseem ceeb los xyuas kom meej cov khoom zoo stability thiab sib xws. Cov nram qab no cov ntsiab lus cov txheej txheem rau precision txhaj molding los ntawm cov kev xav ntawm raw khoom tswj, pwm tsim, txhaj tshuaj parameter optimization, zoo soj ntsuam, txheej txheem ib puag ncig tswj, khoom tu, thiab daim ntawv thov ntawm tshiab technologies.

Precision Txhaj Mould Processing Rhiav

Raw Material Control: Lub hauv paus ntawm Precision Txhaj Moulding

Kev ua haujlwm ruaj khov ntawm cov ntaub ntawv raw ncaj qha txiav txim siab qhov tseeb ntawm kev txhaj tshuaj molded qhov chaw. Resin particles yuav tsum tau peb -stage kev tshuaj ntsuam: Ua ntej, particle uniformity yog sim siv lub laser particle loj analyzer kom ntseeg tau tias particle loj sib txawv tsawg dua los yog sib npaug rau 0.02mm; thib ob, melt flow index yog soj ntsuam siv qhov sib txawv scanning calorimetry (DSC), nrog kev hloov pauv hauv tib pawg tswj hauv ± 5%; Thaum kawg, kev ntsuas cov dej noo yog ua tiav, thiab cov dej noo ntawm cov ntaub ntawv hygroscopic (xws li PA thiab PC) yuav tsum qis dua 0.02%, xav tau lub tshuab nqus tsev ziab ntawm 80-120℃rau 4-6 teev yog tias tsim nyog.

Cov ntaub ntawv raw khoom yuav tsum ua raws li "thawj-hauv, ua ntej- tawm" txoj cai, tswj qhov kub thiab txias ntawm 23 ± 2℃thiab cov av noo ntawm 45% -60%, zam kev tshav ntuj ncaj qha. Cov ntaub ntawv sib txawv yuav tsum tau muab cais tawm nrog cov ntawv qhia meej kom tsis txhob sib xyaw thiab sib kis. Cov ncauj lus kom ntxaws batch rau cov ntaub ntawv raw yuav tsum tau sau tseg, suav nrog cov chaw tsim khoom, hnub tsim khoom, thiab txee lub neej, rau kev taug qab.

Pwm Tsim: Cov Core ntawm Precision Control

Pwm machining precision yuav tsum ua tau raws li IT5 cov qauv, nrog rau qhov ntev ntawm qhov kab noj hniav thiab cov tub ntxhais tswj hauv ± 0.005mm. Thaum siv cov txheej txheem kub khiav, lub rooj vag txoj kab uas hla yuav tsum tau txiav txim siab raws li cov khoom tuab, feem ntau yog 1/3-1/2 ntawm cov khoom phab ntsa tuab, thiab kaw-kho qhov ntsuas kub yuav tsum tau ua, nrog qhov kub sib txawv tsis tshaj ± 1 degree.

Qhov cua groove tsim yog qhov tseem ceeb; qhov tob yuav tsum tsawg dua los yog sib npaug ntawm 0.01mm thiab qhov dav 5-10mm los xyuas kom meej qhov ua tiav ntawm cov pa roj los ntawm cov kab noj hniav, tiv thaiv qhov tsis xws luag xws li scorching thiab cov khoom tsis txaus. Cov kav dej txias yuav tsum nyob ze rau ntawm cov kab noj hniav, nrog rau qhov kev ncua deb ntawm 15-25 hli thiab cov dej ntws tau tswj ntawm 1.5-3m / s, ua kom cov pwm kub tsis sib xws tsawg dua lossis sib npaug ± 2 degree. Tsis tas li ntawd, pwm txoj kev taw qhia mechanism yuav tsum muaj siab precision; qhov kev tshem tawm ntawm cov ncej qhia thiab cov lus qhia bushings yuav tsum tsawg dua los yog sib npaug ntawm 0.003mm los xyuas kom meej pwm kaw.

Txhaj Parameter Optimization: Daim duab ntawm Dynamic Balance

Txoj kev txhaj tshuaj molding yuav tsum muaj qhov sib txuam ntawm "siab- nrawm- kub". Cov theem txhaj tshuaj siv segmented tswj: qis- nrawm puv (5-15mm / s) kom tsis txhob yaj cuam tshuam rau kab noj hniav; nruab nrab- nrawm nrawm (20-50mm / s) kom ntseeg tau tias muaj kev sib kis zoo sib xws; thiab kev kub ceev tuav siab (60-80mm / s) los them rau cov khoom shrinkage.

Lub zog tuav yog feem ntau 60% -80% ntawm qhov siab tshaj plaws txhaj tshuaj. Lub sij hawm tuav yog xam raws li cov khoom phab ntsa thickness, yuav tsum tau 1-1.5 vib nas this rau txhua 1 hli ntawm phab ntsa thickness. Pwm tswj qhov kub thiab txias yuav tsum phim cov khoom siv. Piv txwv li, pwm kub rau PC yuav tsum tau tswj ntawm 80-120 degree, thaum rau ABS nws yuav tsum tau tswj ntawm 50-70 degree. Tsis tas li ntawd, cov ntsia hlau ceev yuav tsum tau hloov kho raws li cov khoom siv melting yam ntxwv, feem ntau ntawm 50-150 r / min, los xyuas kom meej txaus melting thiab tiv thaiv degradation.

Kev soj ntsuam zoo: Precision Management thoob plaws lub neej tag nrho

Kev tshuaj xyuas qhov ntev yog ua los ntawm kev siv lub tshuab ntsuas kev sib koom tes (CMM) nrog qhov ntsuas qhov tseeb ntawm 0.001 hli. Tus nqi CPK rau qhov loj me yuav tsum siab dua lossis sib npaug rau 1.33. Kev tshuaj xyuas qhov muag yog ua los ntawm 200x optical microscope, thiab qhov tsis xws luag xws li shrinkage marks thiab flash tshaj 0.1 hli tsis raug tso cai.

Cov txheej txheem parameter traceability yog tsim los sau cov ntaub ntawv xws li siab, qhov kub thiab txias, thiab lub sij hawm thaum lub sij hawm txhaj tshuaj molding txheej txheem nyob rau hauv lub sij hawm, thiab cov ntaub ntawv yog khaws cia rau tsawg kawg yog 3 xyoo. Kev kho pwm yuav tsum tau ua txhua 500 moulding cycles, nrog rau kev ntxuav qhov chaw ntawm qhov chaw thiab xyuas cov ejector tus pin coj los xyuas kom meej ntev - lub sij hawm pwm raug stability. Tib lub sijhawm, cov cuab yeej ntsuas ntsuas tau ntsuas tsis tu ncua kom ntseeg tau qhov tseeb ntawm qhov ntsuas tau.

Kev Tswj Ib puag ncig: Ib qho tseem ceeb ua ntej rau kev tsim khoom ruaj khov

Lub rooj cob qhia ntau lawm yuav tsum tswj qhov kub thiab txias tsis tu ncua, nrog ntsuas kub ntawm 22 ± 1℃thiab txheeb ze av noo ntawm 50% ± 5%. Kev huv huv ntawm lub rooj cob qhia yuav tsum ua kom tau raws li Chav Kawm 8 cov qauv kom tiv thaiv plua plav thiab impurities los ntawm kev cuam tshuam cov khoom zoo.

Cov khoom siv ua haujlwm yuav tsum muaj kev vibration- pov thawj, nrog rau hauv av vibration amplitude Tsawg dua los yog sib npaug li 0.01mm los tiv thaiv kev co los ntawm kev cuam tshuam kev txhaj tshuaj molding raug. Tsis tas li ntawd, cov cua khiav ceev hauv lub rhiav yuav tsum tau tswj ntawm 0.2-0.5m / s kom tsis txhob pwm kub hloov pauv vim huab cua ntau dhau.

Cov cuab yeej tu: Ib qho tseem ceeb ntsuas kom paub tseeb qhov tseeb

Txhaj tshuaj molding tshuab xav tau kev saib xyuas tsis tu ncua. Lub hydraulic system siab stability yuav tsum tau soj ntsuam txhua hli kom ntseeg tau tias lub siab hloov pauv tsawg dua los yog sib npaug rau ± 0.5MPa. Cov ntsia hlau thiab lub thoob yuav tsum tau ntxuav thiab hnav txhua lub hlis twg; Kev hloov pauv yog tsim nyog thaum hnav tshaj 0.02mm.

Thermocouples nyob rau hauv lub ntsuas kub tswj system yuav tsum tau calibrated txhua rau lub hlis los xyuas kom meej qhov ntsuas kub yog tsawg dua los yog sib npaug rau ± 1 degree. Cov khoom siv lubrication system yuav tsum tau kuaj txhua lub lim tiam kom ntseeg tau tias lubrication zoo ntawm txhua qhov txav mus los thiab txo qhov hnav.

Kev siv thev naus laus zis tshiab: Txhim kho kev ua tau zoo thiab qhov tseeb

Kev nthuav qhia cov cuab yeej ntse ntse suav nrog kev txhim kho cov sensors hauv qhov tseem ceeb ntawm cov pwm thiab cov tshuab txhaj tshuaj molding los saib xyuas qhov ntsuas tsis zoo xws li kub, siab, thiab hloov pauv hauv lub sijhawm. Cov ntaub ntawv tsom xam ua kom tsis siv neeg hloov kho ntawm cov txheej txheem tsis zoo.

AI algorithms yog siv los txhim kho cov txheej txheem ntau lawm. Los ntawm kev kawm los ntawm cov ntaub ntawv keeb kwm kev tsim khoom, cov teeb meem zoo yuav raug kwv yees, thiab cov phiaj xwm hloov kho tau muab ua ntej, txhim kho kev tsim khoom ruaj khov thiab ua haujlwm tau zoo.

Lub hauv paus ntawm kev txhaj tshuaj molding yog nyob rau hauv "micron-level" nthuav dav tswj. Los ntawm kev tswj hwm tus txheej txheem thoob plaws tag nrho cov txheej txheem, cov khoom lag luam qhov ntev ntev tuaj yeem ruaj khov nyob rau hauv ± 0.01mm, thiab qhov hnyav rov tuaj yeem ncav cuag 0.1%, muab kev txhawb nqa kev txhim khu kev qha rau siab -kawg tsim. Nrog kev txhim kho thev naus laus zis tsis tu ncua, kev txhaj tshuaj molding yuav txav mus rau qhov ua tau zoo dua, kev ua tau zoo, thiab kev txawj ntse.
