Mainjiniya akafuna zida zachitsulo zolimba zomwe zimapirira kupanikizika kwambiri, dzimbiri, kapena kuvala kwa abrasive —makamaka pama hydraulic system, mavavu amafuta & gasi, kapena makina apampu othamanga kwambiri — samangosaka * aliyense * wopereka. Amafufuza a fakitale yopangira jekeseni ya mim ndi luso lotsimikizika pa ma superalloys a cobalt-nickel, kuwongolera kolimba kwa GD&T, komanso kulolerana ziro pakusinthika kwa batch-to-batch. Ichi ndichifukwa chake ogulitsa padziko lonse lapansi a OEMs ndi Tier-1 akutembenukira ku Qingdao Qiangsenyuan Technology Co., Ltd.-osati ngati malo opangira ma generic, koma ngati wothandizana nawo waukadaulo wokhazikika pakupanga-kutumiza loop.
Izi ndi zomwe zimawasiyanitsa: samawona MIM ngati njira yodziyimira yokha. Amaziphatikiza mwanzeru m'malo opangira zinthu zolondola kwambiri - momwe zopangira ndalama zimadyetsera makina a CNC, komwe kutentha kumayenderana ndi zofunikira za microstructure, komanso komwe nozzle iliyonse ya cobalt alloy kapena AMS 5387 pampu nyumba imanyamula zinthu zonse kuchokera ku certified billet mpaka lipoti lomaliza la CMM. Tawona makasitomala akusintha kuchoka kuzinthu zitatu (zojambula nyumba → wogulitsa MIM → womaliza) kupita ku gawo limodzi-kudula nthawi yotsogolera ndi 37% ndikuchepetsa kukonzanso kwapakati ndi 92% pa nyumba za silinda za piston.
Mafakitole ambiri a MIM amalimbana ndi zida za alloy apamwamba. T800 yochokera ku Cobalt? Nickel-chromium-molybdenum alloys? Izi si "zakudya zina." Kutsika kwawo kwamafuta kumasiyana ndi 316L osapanga utoto mpaka 18%; mawonekedwe awo a sintering amafuna kuwongolera kokwanira kwa oxygen pang'ono; ndipo makina awo a post-sinter amatsika kwambiri ngati mpweya wa carbon umayenda kupitirira ± 0.02%. Qingdao Qiangsenyuan sapereka chitsimikizo chazitsulo. Gulu lawo limapanga mgwirizano wa feedstock specs ndi ogulitsa zinthu zopangira - ndikutsimikizira chilichonse chomwe chikubwera motsutsana ndi ASTM E1479 ndi ISO 9001:2015 Annex B zofunika. Mu ntchito ina yaposachedwa, adagwira nkhani yobisika ya carbide mu AMS 5387 ufa isanayambe sintering ya nkhani yoyamba-kupulumutsa kasitomala $ 210,000 mu zida zowonongeka ndi kuyenerera.
Kuphatikizika koyima sikutsatsa malonda apa-ndizowona zenizeni. Malo awo ogwirizana ndi ISO amakhala ndi mizere ya MIM yotsekera ndi yotsekera pambali pa ma cell a CNC a 5-axis, ng'anjo zochizira kutentha kwa vacuum, ndi malo owonera pamwamba. Palibe ma handoffs. Palibe mipata yomasulira deta. Makasitomala akatumiza chojambulira cha chodzigudubuza cha winch center shaft chosakhazikika—chokhala ndi 0.015 mm cylindricity callout pa 120 mm OD ndi HRC 58–62 surface hardness—amayendetsa kayeseleledwe ka GD&T *pamaso* kusanthula koyenda kwa nkhungu. Amapereka zizindikiro zochepetsera zomwe zingatseke zotsalira za binder. Amasintha malo omwe ali pachipata kuti achepetse tsamba lankhondo kudutsa kutalika kwa mita 1.2. Ndipo amapereka zolemba zoyamba zokhala ndi malipoti athunthu a metrology - osati kungodutsa / kulephera masitampu.
Kodi oyang'anira zogula zinthu amasamala za chiyani? Osati "teknoloji yapamwamba kwambiri padziko lonse lapansi." Amasamala kuti thupi la valve lifika pa nthawi, limakumana ndi kuyesa kwa ASME B16.34 pa 1.5 × kukakamizidwa kwa utumiki, ndikuyika popanda shimming. Qingdao Qiangsenyuan akupereka chitsimikiziro chimenecho, osati kudzera m'malonjezo, koma kudzera m'malamulo olembedwa: ma cert omwe akubwera omwe adalowetsedwa mu nthawi yeniyeni, ma CMM akuyang'ana pa malo atatu ovuta, kuyezetsa komaliza pamabenchi oyeserera a hydraulic, komanso kutsata kwathunthu mpaka ID ya ng'anjo yamoto ndi kuchuluka kwa sintering ramp. Kuyenda kwawo kowonda kumathandizira ma prototype a zidutswa za 50 ndikukhazikika kwapakatikati mpaka mayunitsi 15,000 / chaka - osapereka zokolola zoyambira.
Kuyang'ana m'tsogolo, wosiyanitsa weniweni sadzakhala yemwe ali ndi makina osindikizira akuluakulu a MIM-koma ndani amene amathetsa kusiyana pakati pa sayansi ya ufa ndi kudalirika kwa ntchito. Qingdao Qiangsenyuan akuzama R&D mu wosakanizidwa kuponyera-MIM njira zikuluzikulu m'mimba mwake, woonda khoma zigawo zikuluzikulu; kukulitsa certification kuphatikiza API 6A ndi NORSOK M-650; ndikumanga mphamvu zamapasa za digito pakulosera kwa sinter kusokoneza ma modeling. Kwa mainjiniya omwe amatchula ma valve okakamiza, maziko a pampu, kapena ma nozzles a aloyi a cobalt - ichi sichinanso. fakitale yopangira jekeseni ya mim. Ndi mnzanu amene amaona moyo wautumiki wa gawo lanu ngati KPI yawo.
