Lapho onjiniyela bayacacisa i-silicon mold casting factory izinsiza zezingxenye zensimbi ezinobuqotho obuphezulu, azigcini nje ngoku-oda izingxenye—zivikela ukuqina kobukhulu ngaphansi kwemithwalo ye-hydraulic ye-MPa engu-300, ukuqhubeka kwe-microstructure ngemva kokwelashwa kokushisa, kanye nobuqotho bomhlaba obusinda udaka olubi kumaphampu asendaweni kawoyela. Lokho kuyiqiniso lokusebenza ngemuva kokusakaza okunembayo namuhla-hhayi ukubekezelelwa kwethiyori kumdwebo, kodwa ukusebenza okulinganisekayo kusevisi.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngesinye sezikhungo ezimbalwa zokukhiqiza e-China lapho ukubunjwa kwe-silicon mold (okuhlukile okukhethekile kokutshala imali kusetshenziswa amagobolondo e-ceramic asuselwa ku-silica) kusetshenziswa ngokuhlelekile kumaalloyi e-cobalt-nickel afana ne-AMS 5387 ne-T800. Senze amavalvu omfutho angaphezu kuka-12,000 kumayunithi okulawula amanzi angaphansi kwe-subsea kusukela ngo-2021—ngalinye lidinga ±0.05 mm ukugxila okubucayi, i-porosity eyiziro yangaphakathi nge-ASTM E192 ngayinye, kanye nokulandeleka okugcwele kusukela ku-alloy eluhlaza ukuya embikweni wokugcina we-CMM. Lelo zinga lokungaguquguquki akwenzeki ngenhlanhla. Kwenzeka lapho ukusakaza kungahlukanisiwe nomshini, ukwelashwa kokushisa, noma ukuqinisekiswa kwe-GD&T—futhi uma iqoqo ngalinye liqala ngezitifiketi zempahla eqinisekisiwe, hhayi iziqinisekiso zabahlinzeki.
Izinqumo ezintathu zobuchwepheshe zihlukanisa ukusebenza kwesikhunta se-silicon ekubunjweni okwamukelekayo—futhi lezi zichaza lokho amakhasimende akuhlolela ngempela ezivivinyweni zasensimini:
- Ukulawula ukwakheka kwegobolondo: Izibophezelo ze-silica sol ezijwayelekile ziqhekeka ngaphezu kuka-1,100°C ngesikhathi sokuthululwa kwe-cobalt alloy. I-QINGDAO QIANGSENYUAN isebenzisa i-silica ehlanganisiwe ye-colloidal + isistimu ye-silica ehlanganisiwe elinganiselwe ku-1,280°C—iqinisekiswe ngokuhlaziywa kwegravimetric eshisayo kuyo yonke indawo yegobolondo. Lokhu kuqeda ama-microfissures abonakala kamuva njengama-void angaphezulu aqala ukukhathala ezindaweni zokuhlala zamasilinda.
- Ukuphathwa kokuqina kokuqondisa: Ngezindlu zesilinda sephampu ye-piston ezinokuguqulwa kodonga okungu-42 mm, siqondisa ukusakazwa ku-17° ukusuka mpo esithandweni somlilo futhi sisebenzisa amapuleti asendaweni abandayo ezindaweni eziwugqinsi. I-X-ray tomography iqinisekisa ukugeleza okuqondile okusanhlamvu kufana nama-vectors wokucindezeleka—okubalulekile ezingxenyeni ze-AMS 5387 ezisebenza ku-450°C.
- Ukukhiya imvilophu ye-post-cast dimensional: Ngokungafani nokusakazwa kwesihlabathi, ukubunjwa kwesikhunta se-silicon kubambe ubukhulu obuqinile—kodwa kuphela uma izibonelelo zomshini zenzelwe iphethini, hhayi ukuqagela. Ithimba lethu lakha isitoko esingu-0.3–0.5 mm ezindaweni ezibucayi zokuvala, bese liqinisekisa ukuhlanekezela kwangemva komshini ngokuqondanisa kwe-laser tracker ezingxenyeni ezifakwe ku-fixture. Amaklayenti abika ukunqatshelwa kwesihloko sokuqala okungu-40% okumbalwa kuma-winch center shaft roller ngenxa yalokhu.
Abanye bangase baphikise ngokuthi imishini ye-CNC iyodwa iletha ukunemba okungcono kunokusakaza. Kodwa lokho kugeja i-physics: ukwenza i-alloy block engu-120 kg T800 ibe isisekelo sepompo engu-22 kg kumosha u-82% wezindleko zempahla—futhi kwethula ingcindezi eyinsalela ebeka engcupheni impilo yokukhathala ekulayishweni okujikelezayo. Ukubunjwa kwe-silicone mold kuqala ukuma eduze kwenetha. Khona-ke izikhungo zethu ezihlanganisiwe zokugaya ama-axis angu-5 zisusa kuphela okudingekayo—ukugcina ukwakheka kokusanhlamvu, ukuqeda izinyathelo zokuqeda ukucindezeleka, nokusika isikhathi sokuhola ngamaviki angu-3.7 kuqhathaniswa nezinye ezifakwe ngomshini ngokugcwele. I-OEM eyodwa yaseNyakatho Melika ishintshe ulayini wayo we-cobalt alloy nozzle kule nqubo eyingxube futhi yehlisa izindleko zeyunithi ngo-29% ngenkathi yelula impilo yesevisi isuka ku-8,200 iye ku-14,600 amahora okusebenza.
Lokho amakhasimende akubuza ngokungaguquki—futhi esikuphendulayo ngaphambi kokukucaphuna—ukuthi ungazigwema kanjani izindlela ezintathu ezivame kakhulu zokuhluleka ekubunjweni kwesikhunta se-silicon esezingeni eliphezulu:
- I-Microshrinkage ekuhlanganeni: Ixazululwe ngemodeli eshisayo yamasistimu wokugenca kanye nokuqapha izinga lokushisa lokuncibilika kwesikhathi sangempela (±1.5°C) phakathi nokuthela—akukho okuhlukile.
- Ukungezwani kokuqina kobuso: Kubhekwana nemijikelezo yokucwilisa igobolondo ezenzakalelayo elinganiselwe ku-viscosity, i-pH, nokusabalalisa usayizi wezinhlayiyana—hhayi umuzwa womsebenzisi.
- I-Dimensional Drift kuzo zonke iziqephu: Ivinjelwa ngokugcina amaphethini ayinhloko kuthuluzi le-Invar elizinzile kanye nokuqinisekisa i-geometry yangaphakathi yegobolondo ngalinye nge-optical profilometry pre-assembly.
Asikuthathi ukulingisa njengenqubo ezimele. Wonke umsebenzi wokubumba isikhunta se-silicon ubuyekezwa kanyekanye ubunjiniyela: Ingabe ingxenye yejometri ilungiselelwe ukuqina okuqondile? Ingabe umjikelezo oshiwo wokwelapha ukushisa we-AMS 5387 ufana nosayizi wokusanhlamvu oqinisiwe wokusanhlamvu? Ingabe ukuqedwa okudingekayo kwe-Ra 0.4 μm kungafinyelelwa ngaphandle kokugaya kwesibili okungafaka engcupheni umonakalo ongaphansi komhlaba? Lezi akuzona izinto zohlu lokuhlola. Ziyizingxoxo—zibhalwe phansi, zibhalwe usuku, futhi zinanyathiselwe kuhlelo lokusebenza.
Uma ubheka phambili, ibhodlela langempela akuwona umthamo-ukujula kwesitifiketi. Ngonyaka ozayo, i-QINGDAO QIANGSENYUAN inweba isikophu se-ISO 13485 ukuze ihlanganise izingxenye zesivivinyo se-cobalt-chromium ye-medical-grade, futhi iqala ukuqinisekiswa okuvela eceleni kwenqubo yayo yokubumba i-silicon ngokumelene ne-NADCAP AC7118 Rev. D ngokulingisa emkhathini. Kungani? Ngoba abasebenzisi bokugcina abasamukeli "kusebenze okokugcina." Bafuna ukuphindaphindwa okubhaliwe-kuzo zonke izinto zokwakha, amajiyometri, kanye nokusebenza kokukhiqiza. Lapho eyakho i-silicon mold casting factory ingaletha izingxenye zephampu ze-AMS 5387 ezinokulandeleka okugcwele kwe-metallurgical, izici ezibucayi eziqinisekiswe i-CMM, kanye nemibiko yokungalandeli eyiziro phakathi nezinyanga eziyi-18 ezilandelanayo, uyeka ukuba umthengisi. Uba yisisekelo.
