UTyalo-mali oluNxibelela kwiZixhobo zoNyango: Isikhokelo soMthengi kwiZixhobo zokuSebenza, ukuchaneka, kunye nokuThobela

1. Kutheni utyalo-mali luhambelana kakuhle namalungu amaninzi esixhobo sonyango

Ukuphosa utyalo-mali (i-wax elahlekileyo) ivumela indawo enye endaweni yee-welds ezininzi, izibophelelo kunye neendibano. Kwizixhobo zonyango - i-retractor blade hub, i-forceps hinge, i-dental-handle body, i-infusion-pump gear yezindlu - oko kuthetha ukuba izithuba ezimbalwa ze-sterile-trap, iindawo ezimbalwa zokungaphumeleli kwe-autoclave-cycle, iindawo ezimbalwa zokugcina zicocekile . Inkqubo ikwagcina iyunifomu yokwakheka kweenkozo, okubalulekileyo kukuziphatha kokudinwa okungapheliyo (i-forceps joint ibona amakhulu amawaka emijikelo) kunye nomphezulu ongaguquguqukiyo ofunwa yi-electropolishing.

Kwimiqulu ye-OEM ye-1,000 ukuya kwi-100,000 yamaqhekeza, ukutyalwa kotyalo-mali kudla ngexabiso eliphantsi kune-5-axis machining yesitokhwe sebha (ngexesha lomjikelo, ukusetyenziswa kwezinto ezikrwada kunye nokutshintshwa kwesixhobo) kwaye kutshiphu kakhulu kunobumba inaliti yesinyithi (MIM) kumalungu angaphezu kwe-80 g. Apho kunzima khona kukufakelwa okusisigxina okuhamba ngexesha elide lokuhlala emzimbeni womntu - ezo zifuna i-ISO 13485 / i-Class III yolawulo olupheleleyo kunye ne-upstream ye-ball-of-paper change-control system; uninzi lwabaxhasi botyalo-mali alumiselwanga loo nto.

2. Ukukhetha izinto eziphathekayo - yeyiphi icandelo lezonyango elisetyenziswa ngabathengi ngokwenene

Umgaqo osebenzayo wesithupha : kwizixhobo ezingenakufakelwa ngokutsha, i-17-4 PH kunye ne-AISI 316L igubungela i-80 % yeemfuno zomthengi. I-Co-Cr-Mo kunye ne-Ti-6Al-4V zigcinelwe iinkqubo zokufakelwa ezifuna izixhobo ezizinikeleyo ze-vacuum, ukuphathwa kwe-atmosphere elawulwayo, kunye neengxelo ezipheleleyo zovavanyo lwe-biocompatibility.

3. Ukuchaneka - luluphi ukunyamezela utyalo-mali olunokuthi lubambe, kwaye apho abathengi baxinga khona

Abaxhasi botyalo-mali baqhuba amabakala e-ISO 8062 CT - i-CT5 yeyona nto ixhaphakileyo yokuthenga, ≈ ± 0.10 mm kwi-25 mm feature; I-CT6 ijikeleze ± 0.20 mm kwinqanaba elifanayo kwaye yinto oyifumana kwiindonga ezingabalulekanga. Amalungu eCast ke adlule kwi-CNC machining yobuso obusebenzayo (ezithwele izihlalo, iibhore zokukhwelana, ibamba imihlathi) apho umthengi afuna ngokwenene ±0.03 mm indawo. Impazamo eqhelekileyo kukulindela i-± 0.03 mm ngqo kwi-casting - ayingokunyamezela ukuphosa, kukunyamezela kwe-CNC, kunye nesakhiwo seendleko sitshintsha ngokufanelekileyo.

Umthengi ka-2026 kufuneka:

• Cacisa i-CT5 + ± 0.03 mm CNC kwiimpawu ezidweliswe kumzobo, kunye neefowuni zobuso obusebenzayo.
• Buza i-Foundry ye- dimensional capability study (Cpk ≥ 1.33) kwizinto ezibaluleke kakhulu ze-3-5 kwiqashiso ngalinye, kungekhona nje ukuhlolwa kwenqaku lokuqala.
• Funa umlinganiselo we-CMM ngogcino-kunye-nogcino-nkcukacha kuyo yonke ibhetshi ye-PPAP / FAIR - hayi iikhalitha kuphela.

4. Ukugqitywa komphezulu - zeziphi iindawo zonyango ezifuna ngokwenene

Ukulahlwa kwezonyango kufuna umphezulu osindayo ekucocweni kwaye angabinawo umthwalo webhayoloji. Ileli yokuthenga-spec yile:

• As-cast + passivation : Ra 6.3 – 12.5 µm — yamkelekile kumalungu angaphakathi, angengawo abambekayo.
• I-CNC igqityiwe + yagqithiswa : Ra 0.8 – 1.6 µm - umgangatho wotyando lwezixhobo zesandla kunye nezindlu zokumpompa.
• Electropolish : I-Ra ≤ 0.4 µm - efunekayo kumalungu aqhagamshelana nemimandla engcolileyo yesigulane, ukuqinisekiswa kokucoca, kunye neninzi ye-Class IIa izixhobo zesandla.
• Ipolishi yesipili : Ra ≤ 0.1 µm — i-premium cosmetic kwiziphatho zesixhobo.

Ukupasa kufuneka kwenziwe ngokwe-ASTM A967 okanye i-A380 kwaye ibhalwe kunye nekhemistri, ixesha lokuvezwa kunye neziphumo zovavanyo. I-Electropolishing kufuneka yenziwe kumgca ozinikeleyo wonyango, kunye nekhemistri yokuhlamba enokulandeleka kwaye inxalenye yokugqibela iphathwe ngokupakisha okucocekileyo.

5. Ukuthotyelwa - umfanekiso onyanisekileyo womthengisi wezonyango

Kulapho kukho ukudideka okukhulu, kwaye apho abathengi kufuneka beve impendulo enyanisekileyo kunomgca wokuthengisa.
