Ha lienjineri li hloka likarolo tse nepahetseng tsa tšepe tse mamellang khatello e matla, ho bola, kapa ho roala—haholo-holo litsing tsa hydraulic, li-valve tsa oli le khase, kapa lipompo tse sebetsang hantle haholo—ha ba batle feela * mofani ofe kapa ofe*.

Ke ka lebaka leo li-OEM tsa lefats'e le barekisi ba Tier-1 ba ntseng ba fetohela ho Qingdao Qiangsenyuan Technology Co., Ltd.-eseng joalo ka setsi sa tlhaho, empa e le molekane oa botekgeniki ea kenelletseng mokhoeng oa ho tsamaisa thepa.
Mona ke se ba khethollang: ha ba tšoare MIM e le mokhoa o ikemetseng. Ba e kopanya ka bohlale ka har'a mokhoa o pharaletseng oa tlhahiso ea tikoloho-moo ho kenya lichelete ho fepa machining a CNC, moo phekolo ea mocheso e lumellanang le litlhoko tsa microstructure, le moo motsoako o mong le o mong oa cobalt alloy kapa AMS 5387 pompo ea ntlo e nang le lisebelisoa tse feletseng ho tloha billet e tiisitsoeng ho ea ho tlaleho ea ho qetela ea CMM. Re bone bareki ba tloha ho tloha ho tse tharo-tier sourcing (design house → MIM vendor → finisher) ho ea ho boikarabello ba ntlha e le 'ngoe-ho fokotsa nako ea ho etella pele ka 37% le ho fokotsa rework ea dimensional ka 92% ho li-cylinder pump cylinder housings.
Lifeme tse ngata tsa MIM li sokola ka lisebelisoa tse phahameng tsa alloy. T800 e thehiloeng ho Cobalt? Li-alloys tsa Nickel-chromium-molybdenum? Tsena ha se "phepelo e 'ngoe feela." Ho fokotseha ha tsona ka mocheso ho fapana le 316L e se nang letheba ho fihla ho 18%; boemo ba bona ba sintering bo hloka taolo e nepahetseng ea khatello ea karolo ea oksijene; mme matla a bona a morao-rao a theoha haholo haeba khabone e hoholeha ho feta ± 0.02%. Qingdao Qiangsenyuan ha e fane ka netefatso ea tšepe. Sehlopha sa bona se kopanya li-feedstock specs le bafani ba thepa e tala-'me se netefatsa lotho e 'ngoe le e' ngoe e kenang khahlano le ASTM E1479 le ISO 9001: Litlhokahalo tsa Annex B tsa 2015. Morerong o mong oa morao tjena, ba ile ba tšoara taba e poteletseng ea khethollo ea carbide ka phofo ea AMS 5387 pele ho sintering ea sehlooho sa pele-ho boloka mofani oa $ 210,000 ka lisebelisoa tse lahliloeng le ho tšoaneleha.
Khokahano e otlolohileng ha se puo ea papatso mona - ke 'nete ea ts'ebetso. Setsi sa bona se lumellanang le ISO se na le mehala ea MIM e kopanyang le ea sintering haufi le lisele tsa CNC tse 5-axis, libopi tsa mocheso oa vacuum, le liteishene tsa tlhahlobo ea optical surface. Ha ho li-handoffs. Ha ho likheo tsa phetolelo ea data. Ha moreki a fana ka setšoantšo bakeng sa "winch center shaft roller" e sa tloaelehang-e nang le 0.015 mm cylindricity callout ka 120 mm OD le HRC 58-62 top hardness-ba tsamaisa GD&T simulation * pele ho * tlhahlobo ea ho phalla ha hlobo.

Ha e le hantle batsamaisi ba thepa ba tsotella eng? Eseng "theknoloji ea maemo a lefats'e." Ba tsotella hore 'mele oa valve o fihla ka kemiso, o kopana le tlhahlobo ea khatello ea ASME B16.34 ho 1.5× khatello ea tšebeletso e lekantsoeng, le ho kenya ntle le ho thothomela. Qingdao Qiangsenyuan e fana ka bonnete boo - eseng ka litšepiso, empa ka taeo e ngotsoeng: li-cert tse kenang tsa thepa tse kentsoeng ka nako ea 'nete, tlhahlobo ea CMM e ntse e tsoela pele liteisheneng tse 3 tse mahlonoko, tlhahlobo ea ho qetela ea ts'ebetso ea libenche tse lekantsoeng tsa hydraulic test, le traceability e felletseng ho fihlela seboping sa ID le sekhahla sa ho chesa.
