Kuvhiya Retractor Blade Hub / Bata Coupling

Iyi ndiyo yepakati hubhu uye mubato-kubatanidza iyo inojoinha inobvisika retractor blade kune inodzoreredzwa-yesimbi-yesimbi retractor mubato (semuenzaniso weBalfour, Finochietto, Army-Navy, Deaver uye Weitlaner maitiro retractor). Chikamu chekudyara chakakandwa muAISI 420 simbi isina tsvina , giredhi remartensitic rinotora nzvimbo yakaoma uye isingapfekere mushure mekupisa kupisa, uye inoshivirira inodzokororwa autoclave / chemiclave sterilization cycles. Kukandira kwekudyara kunobvumira iyo yakawanda-maficha blade-clamp geometry (cam slot, spring recess, alignment pini, hand-pad relief) kuti igadzirwe sechidimbu chisina mawelds. Vazhinji vevatengi vedu vanodzosa-hub vanotsiva 5-axis machined-kubva-bar version ine padhuze-net-shape casting kudonhedza nguva yekutenderera uye mutengo weyuniti mumabhechi e5,000–80,000 zvidimbu.

Zvinotaurwa Nezvinhu

• Standard : AISI 420 (UNS S42000 / EN 1.4021 / ASTM A276 Rudzi 420)
• Mamiriro ekupisa : Yakaomeswa uye yakapfava kusvika ≈ 40–48 HRC pamutengi
• Kuumbwa kwechirevo : ASTM A276; EN 10204 3.1 chemistry chitupa
• Bio-kuenderana kuongorora : ISO 10993-5 cytotoxicity mushumo unowanikwa pakukumbira
• Magnetic : Hongu (martensitic; zivisa kana MRI-conditional dhizaini ichidikanwa)

Dimensional Kugona & Kushivirira

• Kurema : 18-200 g
• Min. Ukobvu hwemadziro : 1.5 mm
• As-cast linear kushivirira : ISO 8062 CT5 (≈ ± 0.10 mm / 25 mm)
• CNC post-machining : ± 0.04 mm pane blade slot, mubato wakabereka, cam pamusoro; coaxiality ≤ 0.05 mm TIR
• Pfeka kuomarara kwepasi : kudzika-inodzorwa kesi-kuomeswa kunowanikwa pane zvinodiwa (kuderedza kuputika kwepasi)
• Kuongorora : 100% yekutanga-chinyorwa CMM, FAIR pamujenya, inodzokororwa kune PPAP-maitiro ekudzora eOEM

Pamusoro Pedzisa Sarudzo

• CNC yapera + yakapfuura : Ra 0.8 - 1.6 µm (yakajairwa)
• Electropolishing : Ra ≤ 0.4 µm (yepamusoro-magumo anogona kushandiswazve zviridzwa)
• Mirror polishing : Ra ≤ 0.1 µm (yenzvimbo inobatwa nemaoko inoyevedza)
• Black oxide / matte coating : inosarudzika kune isingataridzike nzvimbo yekuvhiya

Applications

• Balfour / Finochietto / Weitlaner retractor blade-to-handle couplings
• Mauto-Navy, Deaver, Kelly handheld retractor hub miviri
• Kuzvichengeta retractor mafuremu
• Veterinary surgical retractors

Sei uchisarudza Ningbo Ruican yeChikamu Ichi

• 17+ makore emartensitic Stainless-simbi yekudyara kukanda, mukati-imba vacuum kupisa kurapwa uye kupisa
• Single-chidimbu dhizaini vs. akawanda-weldment magungano (hapana weld kukundikana mapoinzi mune autoclave cycles)
• Chimiro chezviyo chakasimba uye kuoma kweyunifomu nekuda kwekudyara kwekudyara - zviri nani kuneta maitiro pane akaumbwa-uye-akagadzirwa akaenzana mubasa
• Mutengi-zvakanangana nepamusoro kurapwa (electropolis, girazi polish) inowanikwa mumutsara neCNC yedu yekupedzisa sero.

Certification & Regulatory Positioning

• IATF 16949 (inoshanda)
• TS EN 10204 3.1 chemistry uye mechaniki zvitupa - inopihwa pamujeti
• FAIR / ISIR pamujenya, mbishi-material lot traceability
• Project-level ISO 13485 zvinyorwa mapakeji anopihwa pakukumbira; Ningbo Ruican haisi ISO 13485 chibvumirano chekugadzira
•
