Imibuzo Ebuzwa Rhoqo
Zeziphi iifomathi zefayile ekufuneka ndizithumele kwi-RFQ yesitampu?
Thumela zombini iifayile ze-2D kunye ne-3D: umzobo we-PDF onemilinganiselo, ukunyamezela, kunye ne-callout yezinto eziphathekayo, kunye ne-STEP (.stp) okanye i-IGES (imodeli ye-3D. I-SolidWorks (.sldprt) kunye ne-DWG/DXF nazo zamkelwa ngokubanzi. I-STEP ifomathi iyakhethwa kuba ayithathi cala kwaye igcina ijometri ngokuchanekileyo. Bandakanya amagqabantshintshi e-GD&T kumzobo we-2D ukuphelisa ukungacaci kokunyamezela.
Ingaba kubiza malini izixhobo zesitampu zesiko?
Ixabiso lesixhobo lixhomekeke kubunzima benxalenye kunye nohlobo lokufa. Ukubetha okukodwa kuyafa: $2,000–$8,000. Progressive ufa kunye 3-8 izikhululo: $15,000–$80,000. Complex progressive kufa kunye 10+ izikhululo: $80,000–$250,000. Ukudluliselwa kufa kwiindawo ezinkulu: $ 50,000–$200,000. Ukusetyenziswa kwezixhobo zaseTshayina kudla ngokuxabisa i-40-60% ngaphantsi kwezixhobo zasekhaya zase-US/EU zomgangatho olinganayo. Isixhobo lixabiso lexesha elinye elihlawulweyo ngaphezulu komthamo weprogram.
Kuthatha ixesha elingakanani ukufumana iisampulu zokuqala kumthengisi omtsha wesitampu?
Isicwangciso seeveki ezisi-8-14 ukusuka ekuvunyweni kweRFQ ukuya kwiisampulu zenqaku lokuqala. Ukwenziwa kwezixhobo sesona sigaba side kakhulu (iiveki ezi-4-10 zixhomekeke kubunzima). Yongeza iiveki ezi-1 ukuya kwezi-2 zokuzama, umlinganiselo, kunye nokuhanjiswa kwesampulu. Iinkqubo zokungxama zinokucinezela oku ukuya kwiiveki ezi-6 ukuya kwezi-10 ngokucwangciswa kwezixhobo ezikhawulezayo. Iprototype tooling (isixhobo esithambileyo okanye i-3D-printed dies) inokuhambisa iisampulu kwiiveki ezi-2-4 zokuqinisekiswa koyilo ngaphambi kokuzibophelela kwisixhobo sokuvelisa.
Zeziphi iziqinisekiso zomgangatho endizifunayo kumthengisi wesitampu?
Ubuncinci, ISO 9001:2015 kwiindawo zoshishino ngokubanzi. Kwimoto: IATF 16949: 2016 ngumgangatho, kunye ne-PPAP Level 3 amandla. Kwezonyango: ISO 13485. Kwi-aerospace: AS9100 Rev D. Ngaphaya kweziqinisekiso, qinisekisa ubunakho bokuhlola obuyinyani (CMM, SPC), ukulandeleka kwezinto (iziqinisekiso zokusila), kunye nezenzo zogcino lokufa. Uphicotho lwezibonelelo yeyona ndlela ithembekileyo yokuvavanya umgangatho womthengisi.
Kuthekani ukuba amalungu am anemiba esemgangathweni emva kokuba imveliso iqalile?
Ukukhutshwa kweSicelo sokuLungiswa okusesikweni (CAR) esifuna uhlalutyo lonobangela phakathi kweentsuku ezi-5 zokusebenza. Umboneleli oqeqeshiweyo uya kubonelela ngeengxelo ze-8D okanye ze-A3 zokusombulula iingxaki ezichonga unobangela osisiseko, isenzo sokulungisa, kunye nesenzo sokuthintela. Ukuba imiba iyaqhubeka emva kweeCAR ezimbini, yenza uphicotho kwindawo. Ukuba akusonjululwanga kwiintsuku ezingama-30, ufaneleke umboneleli wenkxaso. Uthintelo: kufuna uhlolo lwe-SPC kunye neengxelo zokuhlolwa ngamaxesha athile njengenxalenye yesivumelwano sakho sobonelelo.
Ngaba ndingadlulisela izixhobo zokutywina ezikhoyo kumboneleli omtsha?
Ewe, kodwa vavanya ngononophelo. Iifa ezikhoyo zingathunyelwa kumboneleli omtsha, kodwa umboneleli omtsha kufuneka aqinisekise imeko yokufa, aqinisekise ukuhambelana noshicilelo lwabo (iitoni, ubungakanani bebhedi, ubude be-stroke), kwaye abaleke iindawo zokuzama. Ukuba isixhobo esele sikhona sinxityiwe okanye senzelwe ingcaciso yoshicilelo olwahlukileyo, uhlaziyo okanye isixhobo esitsha sinokubiza kakhulu. Bandakanya izixhobo zobunini kwisivumelwano sakho sobonelelo ukuqinisekisa ukuba ungadlulisela iifa xa kuyimfuneko.
