Makasitomala akamafunsa za 'mtengo wopangira jakisoni wachitsulo', nthawi zambiri amayembekeza kuti apeze nambala yosavuta pagawo lililonse. Ndilo lingaliro lolakwika loyamba. Mtengo wake si mtengo womata; ndi zokambirana zomwe zimayamba ndi chitsanzo cha CAD ndikutha ndi lipoti lomaliza loyendera. Ndi za mtengo wonse wa umwini wa chinthu chogwira ntchito, osati kungogula. Ndawona ma projekiti ambiri akuyimitsidwa chifukwa mawu oyamba amawoneka bwino, koma zobisika zobisika za ntchito zachiwiri, zovuta zamtundu, komanso kuchedwa kwa nthawi yotsogolera sizinayikidwe. Tiyeni tidutse zomwe zimasuntha singanoyo.
Zimayamba ndi Feedstock ndi Geometry
Mtengo wamtengo wapatali wa MIM feedstock - chitsulo cha ufa chosakaniza ndi binder - ndi tikiti yolowera. Koma kusankha aloyi nthawi yomweyo kugawa njira. Mukufuna 17-4PH yosapanga dzimbiri? Zodziwikiratu. Koma pamene ntchito ikuyitanitsa ma nickel-based or cobalt-based alloy pa kukana kutentha kwambiri, monga m'zigawo zina za turbine, mtengo wa ufa ukhoza kulumpha ndi fakitale zisanu kapena kuposerapo. Awa si malo otsika mtengo ngati gawo likufunika kuchita.
Ndiye pali gawo kapangidwe. Geometry yovuta, yophatikizika yokhala ndi ulusi wamkati, makoma opyapyala, ndi ma undercuts ndipamene MIM imawala. Koma 'complex' ili ndi madigiri. Chida chaching'ono, chovuta kwambiri chopangira opaleshoni chitha kugwiritsa ntchito ma gramu 5 okha, koma ngati chikufunika zida zosalimba komanso 99.5% density spec, mtengo wopangira jekeseni wachitsulo imayang'aniridwa ndi zida zolondola komanso zowongolera, osati ma gramu aiwisi. Zida zopangira zida zoterezi ndizojambula zokha.
Ndikukumbukira pulojekiti yomanga nyumba yomwe imayenera kukhala ya hermetic. Mapangidwewo anali ndi chipolopolo chosalekeza, chokhala ndi mipanda yopyapyala. M'malingaliro, ndi abwino kwa MIM. Koma kuthamanga koyambirira kunawonetsa porosity yaying'ono m'magawo enaake, kulephera kuyesa kukakamiza. Tinayenera kusintha kamangidwe ka zipata ndi mbiri ya sintering, zomwe zinawonjezera maulendo angapo oyesera ndi mtengo. Mawu oyamba a kasitomala pagawo lililonse anali opanda tanthauzo panthawiyo. Mtengo weniweniwo unaphatikizapo chitukuko chobwerezabwereza chimenecho.
Sinkhole Yobisika: Ntchito Zachiwiri
Apa ndi pamene bajeti nthawi zambiri imawombera. Malotowa ndi opangidwa ndi ukonde, koma zenizeni pazigawo zambiri zimaphatikizapo ntchito ina ya pambuyo-sintering. Ngati mukufuna chomaliza chopangidwa ndi makina a CNC pankhope yosindikizira, kapena dzenje lobowola bwino lomwe limalekerera kwambiri kuposa momwe sintering ingagwire, mukuwonjezera masitepe. Kampani yomwe imagwira MIM ndi CNC makina m'nyumba, ngati Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ali ndi mwayi pano. Amatha kuwongolera kayendetsedwe ka ntchito kuchokera ku sintered blank mpaka kumaliza pansi pa denga limodzi, lomwe nthawi zambiri limayang'anira mtengo wake kuposa kutumiza magawo kupita kumalo ogulitsa makina ena.
Ganizirani za thupi la valve lopangidwa kudzera ku MIM. Mawonekedwe akulu ndi mayendedwe amkati amawumbidwa, koma nkhope ya flange ingafunike mphero ndipo ulusi wapadoko umafunika kugunda. Ngati wogulitsa wa MIM akuyenera kutsitsa makinawo, mumapeza zolembera ndi kuchedwa. Wophatikizira wophatikizika amatha kuwongolera ndondomekoyi - nthawi zina ngakhale kupanga makina a sintering asanawerengedwe bwino - kuti achepetse zinyalala ndi kasamalidwe. Mbiri yawo yayitali pakuponya ndi kukonza, monga tawonera patsamba lawo tsngtaocnc.com, akuwonetsa kuti amamvetsetsa zakusintha kwamitengo ya hybrid iyi.
Debinding and sintering cycles okha ndi nkhumba zamphamvu. Kuthamangitsa ng'anjo ya alloy yotentha kwambiri ngati cobalt-chrome mix sikufanana ndi chitsulo chokhazikika. Nthawi yozungulira ndiyotalikirapo, mlengalenga ndi wovuta kwambiri, ndipo ng'anjo imavala kwambiri. Kutsika kwamitengo iyi komanso kutsika kwa zida zazikulu kumayikidwa pamtengo wagawo, makamaka pama voliyumu otsika.
Voliyumu ndi Chopindika, Osati Kusintha
Mzere wapamwamba ndi MIM ndi wa voliyumu yayikulu. Izo ndi zoona pang'ono chabe. Ndi mphamvu yokwanira yochepetsera mtengo wa zida zam'tsogolo, zomwe nthawi zambiri zimakhala zokwera kuposa zoponya mafelemu koma zotsika kuposa zopangira ndalama. Malo okoma nthawi zambiri amayamba kuzungulira magawo 10,000 pachaka, koma ndawona kuti ndizomveka kwa magawo 5,000 ngati geometry imachotsa makina a CNC amtengo wapatali a $ 20 pachidutswa chilichonse.
Kuchepetsa mtengo kuchokera ku 10k mpaka 100k sikuli mzere. Zosungira zambiri zimatengedwa ndi 50k yoyamba. Pambuyo pake, mumangofinya m'mphepete ndikukulitsa kugula kwa feedstock. Phindu lenileni la voliyumu ndilokhazikika. Pamathamanga apamwamba, ogwiritsa ntchito amayimba ma parameter, zida zimakhazikika, ndipo chiwopsezo chimatsika. Zokolola zosasinthasinthazi ndizopulumutsa ndalama zambiri, nthawi zambiri zosawerengeka. Zowonongeka ndi kukonzanso zimatha kupha phindu la gawo lotsika mtengo.
Kulephera komwe tidaphunzirako: bulaketi ya chipangizo cha ogula. Tinalandira voliyumu ya zidutswa 100k, zida, ndikuyamba kupanga. Gawolo linagwira ntchito, koma zodzikongoletsera zinali zolimba kuposa momwe timayamikirira. Kusiyanasiyana pang'ono kwamitundu yosiyanasiyana, kovomerezeka ku gawo la mafakitale, kudakhala chifukwa chokanira. Tidawonjezeranso gawo lomaliza logwedezeka lomwe sitinawononge, ndikuchotsa malire omwe akuyembekezeka. The mtengo wopangira jekeseni wachitsulo chitsanzo chinalephera kuwerengera zofunikira zosagwira ntchito.
Kusankha kwa Ma Supplier: Kutha Kupitilira Mawu
Kusankha wogulitsa pamtengo wotsika kwambiri pagawo lililonse ndi njira yachangu yotaya ndalama. Muyenera kuwunika kayendetsedwe kawo. Kodi amawunikidwa bwanji ndi kubweza kusiyana kwa ma feedstocks? Kodi ma statistical process control (SPC) awo pazovuta zazikulu ndi ziti? Kwa kampani ngati QSY, yomwe ili ndi zaka zopitilira 30 popanga ndi kupanga, funso ndi momwe chidziwitso chazitsulo ndi mawonekedwe amasinthira ku machitidwe awo a MIM. Chochitika chimenecho mu kuponya ndalama ndi chipolopolo nkhungu kuponyera aloyi wapadera ndi zogwirizana mwachindunji kumvetsa sintering khalidwe ndi zinthu zomaliza.
Nthawi yotsogolera ndi mtengo wake, nawonso. Wopereka katundu wokhala ndi ndandanda ya ng'anjo yosinthika amatha kutengera magulu achangu kapena mayeso a uinjiniya popanda chiwongolero cha 50%. Izi zimapulumutsa mapulojekiti. Ndibwino kuti ndipereke 10% premium kwa ogulitsa omwe atha kutembenuza gulu loyeserera pakadutsa milungu iwiri kuposa kudikirira milungu isanu ndi itatu kuti ndigule zotsika mtengo.
Funsani za scrap protocol awo. Kodi amangobwezeretsanso zidutswa za sintered ngati zinthu zotsika, kapena atha kuzibwezeretsanso mumtsinje wa feedstock molamulidwa? Izi zimakhudza mtengo wanu wazinthu pamapeto pake. Kuwonetsetsa apa kumalekanitsa malo ogulitsa ntchito ndi ogwira nawo ntchito.
The Total Cost Equation: Kubwezeretsanso
Chifukwa chake, tikamabwereranso ku mtengo wopangira jakisoni wachitsulo, tikukamba za kuchuluka kwake: Tooling Amortization + (Feedstock Cost per Shot + Process Cost per Cycle) / Zokolola + Mtengo wa Sekondale Operations + Logistics/Overhead. Kuphonya kusinthika kumodzi, ndipo bizinesi yanu ikugwedezeka.
Ntchito zotsika mtengo kwambiri za MIM ndizomwe zidapangidwira kuyambira tsiku loyamba, injiniya akugwira ntchito limodzi ndi wopanga wodziwa ntchito. Ndi za kutchula aloyi yoyenera pa ntchitoyi, kulekerera zinthu zofunika zokha, komanso kumvetsetsa zamalonda. Wothandizira yemwe amapereka zonse - kuchokera ku upangiri wazinthu mpaka kuumba, sintering, ndi komaliza CNC makina- Nthawi zambiri amatha kupeza zogwira mtima zomwe magawo ogawanika sangathe.
Pamapeto pake, mtengo wake umatsimikiziridwa ndi momwe gawolo likugwirira ntchito komanso kusunga ndalama zophatikizira. Ngati mukusintha gulu la magawo asanu opangidwa ndi chigawo chimodzi cha MIM, the mtengo wopangira jekeseni wachitsulo pafupifupi alibe ntchito poyerekeza ndi ntchito ya msonkhano, inventory, ndi kudalirika phindu. Ndiko kusintha kwa kawonedwe. Si kugula chinthu; ndi mgwirizano wamtengo wapatali. Nambala yomaliza pa invoice ndi mfundo imodzi yokha ya data pakuwerengera kokulirapo.
