Kev lag luam loj hlob ntawm cov khoom lag luam me me suav nrog cov khoom sib txuas micro, cov khoom siv hluav taws xob uas siv tau, kev kho mob micro catheters thiab cov khoom siv tshuaj pleev ib ce me me ua rau cov ntawv thov dav ntawm micro kub khiav pwm nrog kab noj hniav loj hauv qab 5 hli. Cov qauv txheej txheem thermocouples nrog 1.5mm thiab 3.0mm sheath diameters tsis tuaj yeem ntsia tau rau hauv qhov chaw nqaim tshwj xeeb ntawm micro nozzles, yog li ultra-me me ntxhia-insulated miniature thermocouples nrog 0.3mm-1.0mm sheath dhau los ua cov sensors tshwj xeeb. Piv nrog rau cov kev sojntsuam zoo tib yam, cov thermocouples me me muaj cov qauv tsim tshwj xeeb thiab kev ua tau zoo raws li micro molding scenarios, thaum tseem coj tshwj xeeb kev teeb tsa thiab kev saib xyuas cov kev txwv uas cov neeg tsim pwm yuav tsum ua tib zoo xav.
Ua ntej, ultra- me me txheej sab nraud adapts rau compact micro nozzle sab hauv layout. Micro hot runner nozzles integrates lub tes tsho cua sov, ntws raws thiab valve koob tshuaj nyob rau hauv ib tug me me lub tog raj kheej hlau, tawm tsuas yog 0.3-1.0mm nqaim qhov rau qhov kub thiab txias sojntsuam. Tej yam me me thermocouple seamless nyias- phab ntsa stainless hlau sheath tuaj yeem muab tso rau hauv qhov tshwj xeeb micro qhov yam tsis hloov pwm steel qauv, zam cov nqi pwm ntxiv los ntawm kev hloov cov qauv sojntsuam. L-zoo li tus bent me me sojntsuam ntxiv daws cov kab tuag cov ces kaum sab hauv pwm phaj, thiab kho ultra- cov lus qhia luv luv kom ntseeg tau tias qhov ntsuas ntsuas tau zoo sib xws rau lub qhov rooj qhov rooj qhov kub ntawm qhov chaw, paub meej tias qhov ntsuas kub ntawm lub qhov rooj me me.
Qhov thib ob, ceev thermal teb tshem tawm qhov kub thiab txias ntawm micro melt filling. Cov phab ntsa ntawm cov thermocouples me me yog qhov nyias nyias, thiab cov kab hluav taws xob sab hauv lub tshuab hluav taws xob yog micron- theem, ua rau ultra- qis thermal mass. Thaum lub tshuab hluav taws xob ua hluav taws xob kub kub hloov pauv lossis yaj ntws ua rau qhov ntsuas kub hauv zos hloov pauv, qhov ntsuas qhov ntsuas tuaj yeem rov qab tiag tiag- lub sijhawm ntsuas kub kub rau tus tswj tsis pub dhau 0.2 vib nas this, nrawm dua li 1-3 thib ob cov lus teb qeeb ntawm cov txheej txheem tuab tuab. Rau micro nyias- cov khoom siv phab ntsa nrog phab ntsa thickness tsawg dua 0.2 hli, txawm tias qhov kub thiab txias qeeb yuav ua rau tsis sib xws, txhaj tshuaj luv luv thiab burr tsis xws luag; ceev- teb cov thermocouples me me kom ruaj khov yaj viscosity thiab txhim kho cov khoom tiav qhov sib xws.
Thib peb, kev hloov pauv siab thiab tiv thaiv- kev ua haujlwm qaug zog yoog mus rau cov pwm disassembly. Micro pwm yuav tsum tsis tu ncua nozzle disassembly los ntxuav lub qhov rooj me me cov pa roj carbon deposits, thiab thermocouple cov kab tawm yuav tsum rov khoov thiab rub. Miniature MI thermocouples txais siab - ceev magnesium oxide compaction txheej txheem, thiab sab hauv multi-strand twisted thermoelectric xov hlau tuaj yeem tiv taus ntau dua 500 rov khoov voj voog yam tsis muaj kev puas tsuaj, thaum tib yam nkaus xwb -strand tuab probes tawg tom qab kaum tawm ntawm kev ua haujlwm. Cov kev hloov pauv hloov pauv hloov pauv ntawm qhov kev sojntsuam-kab txuas txuas ntxiv cuam tshuam kev ntxhov siab khoov thiab txo qis kev pheej hmoo tawg ntawm cov kab txuas.
Plaub, tsis tshua muaj cua sov yuav txo qhov ntsuas kub ntawm qhov sib txawv ntawm qhov chaw me me. Txheem tuab probes nyob hauv cov ntim loj hauv micro nozzles, nqus cov cua kub loj los ntawm cov pwm hlau thiab tsim cov dej kub hauv zos, ua rau ntsuas qhov kub ntawm 5-8℃qis dua qhov ntsuas kub. Cov kev sojntsuam me me nyob hauv qhov chaw tsis txaus ntseeg, NW nyuam qhuav cuam tshuam nrog cov thawj thermal teb tshuav ntawm micro hot runners, thiab lub caij nplooj ntoos hlav tiv tauj cov qauv tshem tawm cov huab cua sib txawv thaum tshav kub kub poob, tswj kev ntsuas qhov yuam kev nyob rau hauv ± 1℃rau precision micro molding qauv.
Txawm li cas los xij, cov thermocouples me me muaj qhov txwv tsis pub siv uas tsis tuaj yeem tsis quav ntsej. Nyias sheath phab ntsa ua rau cov neeg kho tshuab tsis zoo; kev sib cuag nrog iav fiber ntau yaj los yog cov pwm ntse npoo yuav yooj yim khawb thiab perforate lub sheath, yog li micro pwm rau reinforced plastics yuav tsum tau hloov mus rau thickened alloy me me probes nrog daim iav polishing. Lub ultra- cov xov hlau sab hauv zoo zoo dua rau qhov siab -kub oxidation, yuav tsum tau luv calibration cycles txhua ob lub hlis rau kev cob qhia ntau lawm. Thaum lub sij hawm installation, qhov tsawg kawg nkaus dabtsi yog khoov vojvoog yuav tsum ncav cuag 8 lub sij hawm lub sheath txoj kab uas hla, nruj dua li 5-lub sij hawm tus qauv ntawm zoo tib yam probes, txwv tsis pub cov xov hlau sab hauv yuav tawg sai heev. Tsis tas li ntawd, cov txheej txheem tsim khoom ntawm cov thermocouples me me muaj qhov yuav tsum tau ua ntau dua, yog li cov nqi khoom siv yog 2-3 npaug siab dua li cov qauv sojntsuam, thiab kev tswj xyuas cov khoom seem yuav tsum paub qhov txawv ntawm ntau txoj kab uas hla kom tsis txhob muaj qhov yuam kev.
Rau cov tuam txhab lag luam pwm koom nrog micro precision txhaj tshuaj molding, xaiv qhov sib txuam me me thermocouples yog lub hauv paus tseem ceeb los daws cov micro kub khiav kub tswj tsis ruaj khov. Tsim nyog kev npaj ntawm kev sojntsuam kev teeb tsa txoj haujlwm thiab cov qauv kev ua haujlwm dabtsi yog khoov tuaj yeem ua rau lub neej ua haujlwm siab tshaj plaws thiab ntsuas qhov tseeb ntawm cov ntsuas me me.
