Bokhoni ba bona bo akaretsa tšepe e entsoeng ka tšepe, tšepe, tšepe e sa hloekang, le li-alloys tse khethehileng (tse kang li-alloys tse thehiloeng ho cobalt le li-nickel), ho netefatsa hore esita le ha ho etsoa prototyping ka thepa e sa tloaelehang, tsebo ea motheo ea boitšoaro ba lintho tse bonahalang e teng.
Bakeng sa bareki ba sebeletsang liindasteri tse kang mechini ea temo, lisebelisoa tsa bongaka, mechini ea indasteri, meepo le lik'hemik'hale tsa petrochemical, QSY e fana ka mofuta o le mong oa ts'ebeletso o ikhethileng. Kaha ba sebelisane 'moho le bareki linaheng tse fetang 20, ba utloisisa maemo a lefats'e a hlokahalang bakeng sa boleng le phano. Hore na o koala lekhalo lipakeng tsa prototype le tlhahiso ea bongata kapa o hloka hore CNC e qetelle likarolong tsa hau, ho sebelisana 'moho le setsi se nang le boiphihlelo ho netefatsa hore phetoho ho tloha ho moralo oa dijithale ho ea ho karolo ea' mele ha e na moroallo, e ka tšeptjoa ebile e ts'oaroa ka maemo a holimo ka ho fetisisa.
Qetello: Potlakisa Nts'etsopele ea Sehlahisoa sa Hao ka ho Lahlela Lehlabathe le Potlakileng
Prototype sand casting e fana ka monyetla oa leano bakeng sa baenjiniere le bahlahisi ba lihlahisoa ka 2026. Ka ho kopanya metallurgy ea setso le tlhahiso ea morao-rao ea dijithale, e fana ka likarolo tsa tšepe tse sebetsang ka lebelo le bonolo le ho fetoha habonolo. Hore na o netefatsa ntlo e ncha ea betri ea EV, ho leka mochini o tsamaisang pompo ea indasteri, kapa ho theha sebopeho sa moetlo, ts'ebetso ena e fana ka botšepehi ba thepa le tokoloho ea geometri e hlokahalang ho atleha.
Bokhoni ba ho pheta-pheta ka potlako ntle le moroalo oa litšenyehelo tse phahameng tsa lisebelisoa li lumella ho ntlafatsa moralo, ho fokotsa likotsi pele ho tlhahiso ea bongata. Ka li-MOQ tse tlase le linako tse etellang pele kapele, u ka tloha mohopolong ho ea ho 'nete ea 'mele ka matsatsi a seng makae.
Ke Mang ea Lokelang ho Nahana ka Tšebeletso ee?
- Baenjineri ba R&D: Ho hloka likarolo tsa tšepe tse sebetsang bakeng sa tlhahlobo.
- Tse qalang: E batla ho netefatsa Hardware ka capital capital e tlase.
- Baetsi: Ho hloka tlhahiso ea borokho ha u ntse u emetse lisebelisoa tsa ka ho sa feleng.
- Baqapi: Ho theha liforomo tse rarahaneng, tse entsoeng ka tšepe bakeng sa lits'ebetso tsa botle.
Na u ikemiselitse ho qala morero oa hau o latelang? Netefatsa hore meralo ea hau e ntlafalitsoe bakeng sa ho etsoa le ho fumana likarolo tsa hau kapele. Ikopanye le sehlopha sa rona sa boenjiniere kajeno bakeng sa tlhahlobo ea mahala ea DFM le quote hang hang.
