Embonini yesimanje yezimoto, ukushisela iminyango kungenye yezinqubo ezidinga kakhulu ngokunemba, ukusebenza kahle, kanye nekhwalithi yendawo. Izicabha zezimoto azigcini nje ngokuba nomthelela ekuqineni kwesakhiwo kodwa futhi zinomthelela ngokuqondile ekusebenzeni kokuvalwa, amazinga omsindo nokudlidliza (NVH), kanye nokubukeka kwemoto iyonke. Ngenxa yalesi sizathu, ukushisela umnyango sekube yisinyathelo esibalulekile sokulawula izinga ekukhiqizeni izimoto.
Iningi lezicabha zezimoto namuhla zenziwa kusetshenziswa-izingqimba eziningi zamashidi ensimbi, ngokuvamile asukela ku-0.6 mm kuya ku-1.2 mm ukujiya. Nakuba lezi zakhiwo ezincane-zamashidi zisiza ukunciphisa isisindo semoto, futhi zenza inqubo yokushisela ibe bucayi kakhulu. Noma yikuphi ukungazinzi ekufakweni kokushisa noma amandla e-electrode kungaholela ekutheleni ngokweqile, kumamaki wokuhlehlisa ajulile, noma ukwakheka kwe-nugget okungahambisani. Lezi zinkinga zikhuphula izindleko zokuphinda zisebenze futhi zingase zonakalise{7}}ukuqina kwesikhathi eside.
Njengoba isivinini sokukhiqiza siqhubeka nokukhula kanye nezidingo zekhwalithi ziba namandla, imishini yokushisela indawo ye-MFDC kancane kancane ithathe indawo yokushisela amabala e-AC. Ngokuzinza kwamanje okuthuthukisiwe nokuhambisana okuphezulu nemigqa yokukhiqiza ezenzakalelayo, ubuchwepheshe be-MFDC benza abakhiqizi bakwazi ukufeza ikhwalithi ephezulu yokushisela kanye nokukhiqiza okukhulayo. Ezinkampanini ezihlela imigqa emisha yokukhiqiza noma ukuthuthukisa amasistimu akhona, ukuqonda indima yokushisela indawo ye-MFDC ekukhiqizeni iminyango kubalulekile ekwenzeni izinqumo zemishini unolwazi.
Isakhiwo Esijwayelekile Nezinselele Zokushisela Ekukhiqizeni Komnyango Wezimoto
Ngaphambi kokuhlola izinzuzo zemishini yokushisela indawo ye-MFDC, kubalulekile ukuqonda ukwakheka kweminyango yezimoto kanye nezinselelo zobuchwepheshe ezihambisana nokushisela. Ukuqonda okucacile kwalezi zisekelo kwenza kube lula ukubona ukuthi kungani kudingeka ubuchwepheshe bokushisela obuphambili.
Izici zesakhiwo se-Automotive Door Assemblies
Umnyango wezimoto ojwayelekile uqukethe izingxenye zensimbi zeshidi ezimbalwa ezihlanganiswe ndawonye ngokushisela amabala amaningi. Isigaba ngasinye sesakhiwo sinezidingo ezihlukile zokushisela, ikakhulukazi mayelana namandla nekhwalithi yendawo.
Ithebula elingezansi lifingqa izingxenye ezijwayelekile zomnyango kanye nezici zazo zokushisela.
