22 G uaSiv rab koobuas tuaj yeem hloov kho tau yooj yim los ntawm cov kws kho mob tau txais kev txhawb nqa los ntawm kev ua haujlwm tsis tshua muaj thiab sophisticated niaj hnub tsim khoom. Nrog rau txoj kab uas hla ntawm 0.7 hli, ib txoj kab uas hla ntawm kwv yees li 0.5 hli, thiab phab ntsa thickness tsuas yog li ntawm 0.1 hli - ntawm no microscopic scale ntawm ob peb millimeters, ua kom muaj zog, siab precision, defect - dawb, thiab sterile ntau lawm yog ib qho nyuaj heev rau cov ntaub ntawv science, precision ua, thiab kev tswj kom zoo. Kev tsim nyog 22G Chiba koob tuaj yeem suav tias yog kev lag luam masterpiece ntawm micro-metric precision manufacturing. Kab lus no yuav pib los ntawm txhua kauj ruam ntawm cov txheej txheem tsim khoom, tshawb xyuas nws cov txheej txheem tseem ceeb, thiab qhia txog qhov yuav luag nruj nruj tswj qhov system uas khiav los ntawm nws.

I. Los ntawm Raw Materials mus rau Yeeb Nkab: Qhov Chaw Pib ntawm Precise Forging

Cov txheej txheem tsim khoom pib nrog cov ntaub ntawv purest. Kev kho mob- qib stainless hlau 316L lossis npib tsib xee-titanium hlau / filament, uas yuav tsum tau ua raws li cov tshuaj muaj pes tsawg leeg thiab biocompatibility ntawv pov thawj.

• Ntau- dhau qhov kev kos duab txias:Qhov no yog cov txheej txheem tseem ceeb rau kev tsim cov raj ultra-zoo hollow raj. Cov khoom siv raw cov yeeb nkab yog raug rau cov yas deformation nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam los ntawm cov pob zeb diamond los yog tawv alloy pwm nrog maj mam txo cov diameters. Sab nraud txoj kab uas hla thiab phab ntsa tuab yog maj mam txo mus rau lub hom phiaj loj (xws li 22G). Cov txheej txheem no yuav tsum muaj kev tswj xyuas meej ntawm kev txo tus nqi ib zaug, kev nrawm nrawm, lubrication, thiab cov txheej txheem annealing. Ib qho kev tsis sib xws yuav ua rau cov phab ntsa tsis sib xws, cov phab ntsa sab hauv, lossis cov pob txha tawg.
• Kev kho sab hauv sab hauv:Cov phab ntsa sab hauv ntawm cov hlab ntsha tuaj yeem muaj cov kab mob me me. Los ntawm txoj kab uas hla ntawm polishing los yog kua sib tsoo, lub puab kab noj hniav yog xyuas kom ncav cuag ib daim iav -zoo li nto tiav, uas yog ib qho tseem ceeb rau kev txo cov nqus dej, tiv thaiv cov qauv adhesion, thiab xyuas kom meej kev txhaj tshuaj.

II. Needle Tip Forming: Tus Ntsuj Plig ntawm Piercing Performance

Lub taub hau yog qhov tseem ceeb ntawm kev txiav txim siab qhov kev xav, cov ntaub so ntswg puas, thiab qhov ua tau zoo. Kev tsim khoom ntawm 22G koob taub yog tshwj xeeb tshaj yog ua kom zoo.

• Precision sib tsoo:Ntawm lub tshuab CNC sib tsoo, lub log sib tsoo nrog lub kaum ntse ntse thiab qhov loj me yog siv los ua oblique sib tsoo ntawm qhov kawg ntawm lub raj, tsim ib lub dav hlau classic inclined ntawm kwv yees li 20-30 degrees. Lub kaum sab xis no tau raug pov thawj los ua tus qauv kub los ntawm ntau xyoo ntawm kev sim tshuaj: nws ua kom muaj qhov ntse txaus kom nkag mus tau yooj yim thaum tseem tso cai rau "sliding" nyhuv es tsis yog xuas nrig ntaus thaum tho cov hlab ntsha (xws li cov kua tsib). Kev sib tsoo yuav tsum ua kom lub dav hlau du tsis muaj burrs lossis frays.
• Side Hole Processing:Nyob rau sab nraub qaum ntawm rab koob lub dav hlau inclined, siv laser drilling lossis micro-tsim hluav taws xob tawm tshuab tshuab, ib sab qhov nrog txoj kab uas hla ntawm kwv yees li 0.3 hli yog machined. Kev ua laser muaj cua sov me me- cuam tshuam cheeb tsam thiab cov npoo du; hluav taws xob paug machining muaj siab precision heev. Cov npoo npoo du tiv thaiv kev txiav ntawm cov ntaub so ntswg strips, kom ntseeg tau tias tau txais cov qauv ntawm tes ua tiav.

III. Surface Finishing and Treatment: Kom Smoothness

• Electrolytic polishing:Qhov no yog ib kauj ruam tseem ceeb rau kev txhim kho qhov zoo ntawm qhov chaw. Los ntawm immersing lub koob lub cev nyob rau hauv lub electrolyte raws li lub anode, los ntawm electrochemical cov tshuaj tiv thaiv, lub microscopic protrusions nyob rau saum npoo yog xaiv yaj, ua rau ib tug uniform, ci iab, thiab kev nyuaj siab -dawb nto. Qhov no tsis yog tsuas yog txo cov kev sib txhuam ntawm cov ntaub so ntswg thaum lub sij hawm puncture tab sis kuj tshem tawm cov kab nrib pleb ntawm qhov chaw, yog li ua kom muaj zog qaug zog thiab corrosion kuj ntawm rab koob lub cev.
• Ntxuav thiab passivation:Rau stainless hlau koob, acid ntxuav thiab passivation kev kho mob yuav tsum tau. Ib tug ntom chromium oxide passivation zaj duab xis yog tsim rau ntawm qhov chaw, uas yog qhov kawg barrier rau nws zoo heev corrosion kuj.

IV. Kev Tswj Xyuas Zoo

Kev tswj kom zoo tsis yog theem kawg; es, nws yog kev koom ua ke rau hauv txhua thib ob los ntawm raw cov ntaub ntawv mus rau qhov kawg khoom.

• Dimensions thiab geometric raug:Siv lub laser txoj kab uas hla ntsuas ntsuas (nrog rau qhov tseeb ntawm 0.1 μm) txhawm rau tshuaj xyuas tag nrho cov kab uas hla; siv lub tshuab kho qhov muag lossis ntsuas qhov muag kom pom lub kaum sab xis, txoj kab nqes ntev, thiab sab qhov chaw; siv lub ntsuas cua hloov mus rau qhov ntsuas qhov nruab nrab ntawm qhov smoothness.
• Surface Integrity:Ua random soj ntsuam ntawm lub ntsis thiab sab qhov npoo nyob rau hauv ib tug scanning electron microscope kom paub tseeb tias tsis muaj burrs, tawg, thiab lwm yam. Siv lub ntsuas roughness saum npoo los ntsuas tus nqi Ra (feem ntau yuav tsum tau ua<0.2 μm).

Kev ntsuas kev ua haujlwm ua haujlwm:

Piercing force test: Kuaj qhov piercing force siv cov ntaub so ntswg simulated los xyuas kom meej qhov zoo sib xws.

Flowability thiab flow rate test: Ntsuas tus nqi ntws siv cov kua dej viscosity kom ua tau raws li qhov yuav tsum tau ua.

Kev ntsuas lub zog sib txuas: Ntsuas qhov sib txuas ntawm lub zog ntawm rab koob thiab lub koob raj.

• Biological Performance thiab sterility assurance:Ua cov kev sim biocompatibility xws li cytotoxicity, rhiab heev, thiab khaus khaus raws li ISO 10993. Cov khoom kawg yog sterilized los ntawm ethylene oxide los yog gamma hluav taws xob thiab dhau mus kuaj tsis muaj menyuam thiab kuaj kab mob endotoxin.
• Tag nrho traceability thoob plaws hauv tus txheej txheem:Los ntawm batch tus naj npawb ntawm cov ntaub ntawv raw mus rau qhov kev tsim khoom ntawm txhua tus txheej txheem, cov neeg ua haujlwm, thiab cov ntaub ntawv ib puag ncig, tag nrho cov khoom siv hluav taws xob tau kaw. Txhua rab koob muaj tus lej tshwj xeeb batch thiab cov ntaub ntawv tsim khoom cuam tshuam nrog nws.

Xaus

Kev tsim ntawm 22G Chiba koob yog cov txheej txheem engineering uas hloov cov kev xav tau ntawm kev kho mob macroscopic rau hauv kev siv lub cev me me. Nws tus nqi yog tsis nyob rau hauv lub preciousness ntawm cov ntaub ntawv, tab sis nyob rau hauv lub relentless nrhiav ntawm precision, kev ua tau zoo, thiab kev cia siab rau ntawm lub siab zoo scale. Txhua qhov tsim nyog 22G Chiba koob yog qhov kev txhais lus zoo tshaj plaws ntawm kev sib koom ua ke ntawm "craftsmanship" thiab "technology." Nws yog qhov tseeb qhov kev xav zoo, yuav luag obsessive, nyob rau hauv cov ntsiab lus me ntsis uas muab cov kws kho mob cov kev ntseeg siab thiab kev lees paub los daws cov kev phais nyuaj nrog cov koob zoo. Rau cov tuam txhab, kev paub txog cov txheej txheem tsim khoom ntawm 22G Chiba koob yog qhov kawg tshwm sim ntawm lawv cov kev siv zog thiab kev tswj xyuas zoo.
