Opanga Opaleshoni Yophatikiza / Hinge Pin Bwana

Ili ndiye hinge yapakati yomwe imalumikizana ndi magawo awiri a zida zopangira opaleshoni, chotengera singano, choletsa udzudzu kapena haemostat ndikunyamula pini ya rivet / screw. Gawoli ndi ndalama zoponyedwa mu 17-4PH zitsulo zosapanga dzimbiri , yankho lothandizidwa ndi mvula yowumitsidwa ku H900 (≈ 44 HRC) kuti ipatse olowa mphamvu yamphamvu kwambiri, kukana kuvala, kuchitapo kanthu kwa kasupe, ndi kukana kwa dzimbiri kosapanga dzimbiri kudzera mu nthunzi yobwerezabwereza, autoclave ndi EtO yotseketsa. Pambuyo poponya, mahinji onse amapangidwa ndi CNC (kubowola, nkhope, mawonekedwe) kuti akwaniritse bwino lomwe maopaleshoni amayembekeza - palibe kusewera kwa axial, kuyenda mopitilira muyeso, osapumira. Gawoli limalowa m'malo mwa makina a CNC amitundu yambiri a 17-4PH bar stock yokhala ndi mawonekedwe apafupi ndi ukonde omwe amapulumutsa 30-50% yazinthu zopangira ndi 20-35% ya nthawi yozungulira ya makulidwe a batch a zidutswa 1,000-50,000.

Zofunikira Zakuthupi

• Muyezo : 17-4PH (AISI 630 / ASTM A564 Kalasi 630 / EN 1.4542 / UNS S17400)
• Kutentha kwa kutentha : H900 (480 °C / 1 h / mpweya wozizira) - 44 HRC, ≥ 1,310 MPa UTS
• Zolemba za ASTM A564 Mtundu wa 630; operekedwa ndi EN 10204 3.1 chemistry satifiketi
• Kuwunika kwa Bio-compatibility : ISO 10993-5 lipoti la mayeso a cytotoxicity likupezeka pofunsidwa ndi labu yodziyimira pawokha
• Maginito : Otsika / pafupi-zero pambuyo pa H900 (zambiri; osati zofunikira zoyendetsedwa ndi zida zosayika)

Dimensional Kutha & Kulekerera

• Kulemera kwake : 4 g - 80 g (cholumikizira cholumikizira mphete)
• Min. khoma makulidwe : 1.2 mm
• Kulekerera kwamtundu wa As-cast : ISO 8062 CT5 (≈ ± 0.10 mm pa mawonekedwe a 25 mm); CT4 yolimba (± 0.08 mm) yotheka pazida zamakina
• CNC post-machining : ± 0.03 mm pa hinge bore ndi nkhope zokwerera; ≤ 0.05 mm TIR
• Pini ya hinge inali ndi makulidwe : Ra 0.8 µm; galasi-lapped kuti Ra 0.4 µm zilipo
• Kuyang'anira : 100% nkhani yoyamba ya CMM (Zeiss Contura), kuwunika kwapakatikati, kutsata kwamlingo wambiri pa EN 10204 3.1

Zosankha Zomaliza Zapamwamba

• As-cast + tumbling : Ra 6.3 - 12.5 µm (zovomerezeka pamalumikizidwe ambiri osakongoletsa amkati)
• CNC inatha : Ra 0.8 - 1.6 µm pa nkhope zogwira ntchito
• Electropolishing : Ra ≤ 0.4 µm, imachotsa kutentha komanso kuyeretsa
• Passivation pa ASTM A967 / A380 : muyezo pamagawo onse opangira opaleshoni
• Black oxide / DLC zokutira : kusankha kwa zokutira zodziwika (monga mabanja a zida zamitundu)

Mapulogalamu

• Opaleshoni yopangira mphete (Mayo, Metzenbaum, Kelly)
• Zonyamula singano (Mayo-Hegar, Mathieu, Crile-Wood)
• Udzudzu / Halsted / Kelly / Crile haemostats
• Ma tubing clamps ndi matumbo forceps
• Mabanja a zida zotayika komanso zogwiritsidwanso ntchito (zida zamankhwala za Gulu I ndi Gulu la IIa)

Chifukwa Chosankha Ningbo Ruican Pagawoli

• Maloko olondola a 17-4PH : Zaka 17+ za kuyika ndalama ndi chithandizo cha kutentha kwa martensitic zosapanga dzimbiri - timapereka kuuma kosasinthasintha kuyambira maere kupita ku maere (omwe amakhala ± 2 HRC)
• Kuchuluka kwa mawonekedwe apafupi : 30–50% kupulumutsa kwaiwisi poyerekeza ndi makina-kuchokera ku bar, 20–35% kupulumutsa nthawi yozungulira
• M'nyumba CNC : kumaliza, mphero ndikubowola pakati mu selo limodzi lodzipatulira kuti zida zikhale zotsika.
• Zojambula : gwiritsani ntchito STEP / IGES / zojambula zanu - timayendetsa DFM (mapangidwe opangira + makina) ndikufotokozeranso mkati mwa 48 h

Certification & Regulatory Positioning

• IATF 16949 (yovomerezeka)
• TS EN 10204 3.1 satifiketi zamakina ndi makina - Zoperekedwa pagawo lililonse
• ISO 19011 / ISO 9001 ndondomeko yoyambira yotengera cholowa kudzera ku IATF
• Zolemba zamapulojekiti za ISO 13485 (Fayilo Yowopsa, Zigawo za Fayilo Yambiri Yopanga, zowongolera zosintha) zophatikizidwa popempha - zindikirani kuti Ningbo Ruican si wopanga mgwirizano wa ISO 13485; timagwira ntchito ngati othandizira pansi pa Pangano Lanu Labwino ndi uinjiniya, makina, kufufuza ndi kufufuza deta yokwanira kuthandizira dongosolo lanu lolamulira la ISO 13485 / 21 CFR 820 / MDR Class I-IIa.
