Zuba Jari don Na'urorin Likita: Jagorar Mai Saye zuwa Kayayyaki, Madaidaici, da Biyayya

1. Me yasa simintin saka hannun jari ya dace da yawancin kayan aikin likita

Yin simintin saka hannun jari (ɓataccen kakin zuma) yana ƙyale sashi guda ya maye gurbin welding da yawa, maɗaurai da taruka. Don kayan aikin likitanci - cibiya mai ɗaukar ruwa mai ɗaukar hoto, madaidaicin ƙarfi, jikin haƙori, rukunin jiko-pump gear gidaje - wanda ke nufin ƙarancin ƙarancin tarko, ƙarancin gazawar autoclave-cycle, ƙarancin sassa don kiyaye tsabta . Tsarin kuma yana kiyaye tsarin tsarin hatsi, wanda ke da mahimmanci ga halayen gajiya mara ƙarfi (haɗin gwiwar tilastawa yana ganin dubban ɗaruruwan hawan keke) da kuma daidaitaccen saman da ake buƙata na lantarki.

Domin OEM kundin na 1,000 zuwa 100,000 guda, zuba jari simintin yawanci rahusa fiye da 5-axis machining na mashaya stock (a sake zagayowar lokaci, raw-material amfani da kayan aiki canji-overs) da muhimmanci mai rahusa fiye da karfe allura gyare-gyare (MIM) ga sassa fiye da ~ 80 g. Inda yake gwagwarmaya shine abubuwan da aka dasa su na dindindin waɗanda ke wucewa ta tsawon lokacin jikin mutum - waɗanda galibi suna buƙatar cikakken ikon ISO 13485 / Class III da tsarin sarrafa canjin takarda; yawancin masu zuba jari ba a kafa su don haka ba.

2. Zaɓin kayan abu - abin da masu siyan kayan aikin likitanci ke amfani da su

Dokokin aiki na babban yatsan hannu : don kayan aikin da ba a sake amfani da su ba, 17-4 PH da AISI 316L suna rufe 80% na bukatun mai siye. Co-Cr-Mo da Ti-6Al-4V an kebe su don shirye-shiryen dasawa waɗanda ke buƙatar keɓancewar kayan aikin injin, sarrafa yanayin yanayi, da cikakkun rahotannin gwajin haɓakawa.

3. Daidaitawa - abin da tolerances zuba jari simintin zai iya riƙe, da kuma inda masu saye ke makale

Masu saka hannun jari suna gudanar da maki ISO 8062 CT - CT5 shine mafi yawan siye-spec, ≈ ± 0.10 mm akan fasalin 25 mm; CT6 yana kusa da ± 0.20 mm akan fasalin iri ɗaya kuma shine abin da kuke samu akan bangon da ba su da mahimmanci. Sassan simintin gyare-gyare sannan su bi ta hanyar injin CNC don fuskoki masu aiki (kujeru masu ɗaukar nauyi, mating bores, ƙwanƙwasa jaws) inda mai siye yana buƙatar gaske ± 0.03 mm matsayi. Kuskure na yau da kullun shine tsammanin ± 0.03 mm kai tsaye daga simintin - wannan ba juriya ba ce, juriyar CNC ce, kuma tsarin farashi yana canzawa daidai da haka.

Mai siye 2026 ya kamata:

• Ƙayyade CT5 + ± 0.03 mm CNC akan abubuwan da aka jera akan zane, tare da kira don kowace fuska mai aiki.
• Tambayi kafuwar don nazarin iya juzu'i (Cpk ≥ 1.33) akan mafi mahimmancin fasali 3-5 a kowace kuri'a, ba kawai binciken labarin farko ba.
• Ana buƙatar ma'aunin CMM tare da adana-da-ajiya don kowane PPAP / FAIR batch - ba kawai calipers ba.

4. Ƙarshen saman - abin da sassan likitanci ke buƙata a zahiri

Simintin gyare-gyare na likita yana buƙatar saman da ke tsira daga tsaftacewa kuma baya ɗaukar nauyin halitta. Tsani na siya-spec shine:

• As-simintin + wucewa : Ra 6.3 - 12.5 µm - karɓuwa don ɓangarori na ciki, marasa hannu.
• CNC gama + wucewa : Ra 0.8 - 1.6 µm - daidaitaccen kayan aikin hannu na tiyata da gidajen famfo.
• Electropolish : Ra ≤ 0.4 µm - ana buƙata don sassan da ke tuntuɓar yankunan marasa lafiya, don tabbatar da tsafta, da yawancin kayan aikin Class IIa na hannu.
• Murfin madubi : Ra ≤ 0.1 µm - kayan kwalliyar ƙima akan kayan aikin hannu.

Dole ne a yi wucewa ta ASTM A967 ko A380 kuma an rubuta su tare da sunadarai, lokacin fallasa da sakamakon gwaji. Electropolishing ya kamata a yi a cikin keɓewar layin likita, tare da gano sinadarai na wanka da kuma ɓangaren ƙarshe a cikin marufi mai tsabta.

5. Biyayya - hoto na gaskiya ga mai simintin simintin gyaran gyare-gyare na likita

Wannan shi ne inda rudani da yawa ke faruwa, kuma inda masu saye ya kamata su ji amsar gaskiya maimakon layin tallace-tallace. Yawancin madaidaicin masu saka hannun jari - gami da mu - ba masana'antun kwangilar ISO 13485 bane. ISO 13485 daidaitaccen tsarin tsarin inganci ne ga masana'antun da aka gama na'urar likita . Mai simintin simintin simintin gyare-gyaren kayan aiki ne, kuma rawar da suke takawa a cikin tsarin ingancin kayan aikin likitanci yana ƙarƙashin Yarjejeniyar Ingancin mai siye da tsarin tsari (FDA 21 CFR 820, EU MDR, NMPA, da sauransu).

Don haka abin da babban mai saka jari na likita ya kamata ya iya bayarwa a cikin 2026 shine:

• IATF 16949 (ko ISO 9001) tsarin ingancin tushe - namu shine IATF 16949, tare da tarihin shekaru 17+.
• TS EN 10204 3.1 Chemistry da takaddun injiniya ta kowace zafi / yawa
• GASKIYA / ISIR a kowace kuri'a - cikakken rahoton PPAP daidai da ya haɗa da bayanan CMM, bayanan taurin da Rahoton Gwajin Abu.
• Nemowa da yawa daga lambar zafin niƙa har zuwa ƙarshen sashe na serial - Tunawa da rukunin ku ya yi aiki.
• Bayanin REACH / RoHS a kowace ka'ida (EU MDR, UKCA).
• TS EN ISO 10993-5 Binciken cytotoxicity akan buƙatun , yana gudana ta hanyar dakin gwaje-gwaje mai zaman kansa.
• Rubutun jiyya na saman (zazzagewa ta ASTM A967, girke-girke na lantarki, tsaftar bayan tsari).
• Canjin ƙira-canjin / injiniyan-canjin tsari don haka kowane zane ko canjin tsari yana haifar da ECN zaku iya amincewa.

Abin da mai saka hannun jarin likita bai kamata ya yi alkawari ba shine tsarin sarrafawa na Class III, ingantaccen fakitin bakararre, alamar UDI, sa ido bayan kasuwa, ko aikin ɗaukar alhakin na'urar. Waɗanda suke zaune tare da OEM.
