Iqhaza Lozakwethu Bokukhiqiza Abanolwazi

Ngenkathi imigomo ye-prototype ye-sand casting iqondile, ukuzenza ngokunemba kudinga ubuchwepheshe obujulile bemboni. Yilapho abakhiqizi abaziwayo abathanda khona I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) ukuletha inani elibalulekile. Ngesipiliyoni seminyaka engaphezu kwengu-30 embonini yokulingisa nokwenza imishini, i-QSY iye yavela ekukhiqizweni kwevolumu ephezulu yaya ekusekeleni izixazululo eziguquguqukayo, ezenziwe ngokwezifiso.

Nakuba i-QSY igxile ekubunjweni kwesikhunta segobolondo, ukukhishwa kwe-wax elahlekile (yokutshalwa kwezimali), kanye nokwenza imishini ye-CNC, ingqalasizinda yabo ebanzi-kuhlanganise neshabhu yokukhiqiza yokukhiqiza engamamitha-skwele angama-50,000-isekela ukuqonda okuphelele kwe-metallurgy kanye nokuguquguquka kwesikhunta. Amandla abo adlulela ku-iron cast, insimbi, insimbi engagqwali, nama-alloys akhethekile (njengama-alloys asekelwe ku-cobalt kanye ne-nickel), ukuqinisekisa ukuthi noma ngabe i-prototyping ngezinto ezingavamile, ulwazi oluyisisekelo lokuziphatha okubonakalayo lukhona.

Kumakhasimende asebenzela izimboni ezifana nemishini yezolimo, okokusebenza kwezokwelapha, imishini yezimboni, izimayini, namakhemikhali e-petrochemicals, i-QSY inikeza imodeli yesevisi eyenziwe ngokwezifiso eyodwa-stop. Njengoba besebenzisane namakhasimende emazweni angaphezu kuka-20, bayawaqonda amazinga omhlaba adingekayo ngekhwalithi nokulethwa. Kungakhathaliseki ukuthi uvala igebe phakathi kwe-prototype nokukhiqizwa ngobuningi noma udinga ukuqedwa kwe-CNC eyinkimbinkimbi ezingxenyeni zakho zabalingisi, ukusebenzisana nebhizinisi elinolwazi kuqinisekisa ukuthi ukuguquka ukusuka ekwakhiweni kwedijithali kuya engxenyeni ebonakalayo akunazihibe, kuthembekile, futhi kugcinwe ezindinganisweni zekhwalithi ephezulu kakhulu.

Isiphetho: Sheshisa Ukuthuthukiswa Komkhiqizo Wakho Ngokusakazwa Kwesihlabathi Okusheshayo

I-prototype ye-sand casting inikeza inzuzo yamasu konjiniyela nabathuthukisi bemikhiqizo ngo-2026. Ngokuhlanganisa insimbi evamile nokukhiqizwa kwedijithali yesimanje, iletha izingxenye zensimbi ezisebenzayo ezinejubane elingakaze libonwe kanye nokuguquguquka. Kungakhathaliseki ukuthi uqinisekisa indlu yebhethri ye-EV entsha, uhlola impompi ye-industrial, noma udala isici sokwakha ngokwezifiso, le nqubo ihlinzeka ngokuthembeka kokubalulekile kanye nenkululeko yejometri edingekayo ukuze kuphumelele.

Amandla okuphindaphinda ngokushesha ngaphandle komthwalo wezindleko eziphezulu zamathuluzi avumela ukwenziwa ngcono kwedizayini, ukunciphisa izingozi ngaphambi kokukhiqiza ngobuningi. Ngama-MOQ aphansi kanye nezikhathi zokuhola ezisheshayo, ungakwazi ukusuka kumqondo uye kungokoqobo okungokoqobo ngezinsuku nje.

Ubani Okufanele Acabangele Le Nsiza?

• Onjiniyela be-R&D: Idinga izingxenye zensimbi ezisebenzayo ukuze zihlolwe.
