Njira yopangira jakisoni ndiyoyenera kupanga zinthu zambiri zapamwamba komanso zida zovuta kwambiri. Njira yopangira jekeseni imadalira kwambiri mapangidwe ndi zipangizo zomwe zimagwiritsidwa ntchito popanga. Chifukwa chake, opanga omwe amafunafuna njira zosavuta zopangira zida kuti apange zinthu zabwinoko pamtengo wotsika amatembenukira ku jekeseni wa aluminiyamu.
Zachikhalidwezinthu zopangira aluminiumakhoza kupangidwanso. Komabe, akadali ndi zophophonya zambiri, kulolerana kwazinthu ndizokulirapo, ndipo zina zimafunikira kukonza kwachiwiri komanso kusukulu. Chifukwa ndizovuta kwa iwo kutsimikizira kupanga mwachangu. Tikambirana za ubwino, kuipa, ndi mawonekedwe a jekeseni wa aluminiyamu.
Jekeseni ndi chiyaninkhungu aluminiyamu maziko?
Ndi kupita patsogolo kosalekeza kwa sayansi ya chikhalidwe cha anthu ndi ukadaulo komanso chitukuko champhamvu chakukula kwamakampani padziko lonse lapansi, themafakitale a powder metallurgyimakula mofulumira chifukwa cha ubwino wake wambiri, ndipo luso lake lamakono lakhala likugwiritsidwa ntchito kwambiri m'magulu ankhondo, zamayendedwe, zamakina, zamagetsi, zamlengalenga, zandege, ndi zina.
MIM (kuumba jekeseni wachitsulo)kudyetsa ndiye pachimake cha zitsulo jekeseni akamaumba mankhwala ndondomeko kukonzekera, amene ndi ufa zitsulo ndi akamaumba wothandizila malinga ndi gawo lina pa kutentha, mu makina kusakaniza kwa nthawi kutentha kusanganikirana. Ndiye kupyolera mu wononga extrusion kudula granulation, mu jekeseni akamaumba chakudya.
Ngakhale kuti zinthu za aluminiyamu zimakhala ndi mphamvu zochepa, mphamvu zake zimakhala zokwera kwambiri, zomwe ziri pafupi kapena kuposa zitsulo zamtengo wapatali. Ili ndi pulasitiki yolimba, matenthedwe abwino amafuta, kukana kwa dzimbiri, komanso kuwongolera kwamafuta. Ma aloyi ena a aluminiyamu amatha kupeza zinthu zamakina abwino komanso mawonekedwe akuthupi kudzera mumankhwala otenthetsera, komanso amathanso kupeza kukana kwa dzimbiri mwa anodizing.
Chifukwa cha miyambo ya aluminiyamu aloyi mbali njira kupanga, mphamvu otsika kupanga, zovuta processing mtengo, ndi dongosolo zovuta za processing mankhwala sangathe kutuluka, wakhala analephera kwathunthu kukwaniritsa zosowa za mofulumira chitukuko cha makampani amakono kupanga chikhalidwe.
Choncho, m'pofunika kupereka zotayidwa mim zitsulo jekeseni akamaumba chakudya choyenerazitsulo jekeseni akamaumba ndondomeko.
Kodi ndi zinthu ziti zogwiritsa ntchito ukadaulo wa Metal injection molding aluminium?
Pazifukwa izi, m'pofunika kupereka chakudya cha aluminiyamu jekeseni akamaumba, mbali zotayidwa jekeseni jekeseni, ndi njira kukonzekera, kuphatikizapo zotayidwa aloyi jekeseni akamaumba chakudya, zotayidwa jekeseni akamaumba chakudya njira kukonzekera, zotayidwa aloyi jekeseni akamaumba mbali, ndi zotayidwa akamaumba jekeseni mbali njira kukonzekera. Itha kutchulidwanso ngati chakudya chopangira jakisoni wa aluminiyumu ndi njira yake yokonzekera ndi magawo opangira jakisoni wa aluminiyumu ndi njira yake yokonzekera.
Chakudya chomangira jakisoni wa aluminiyamu chimakhala ndi ufa wa aluminiyamu ndi wowumba pamlingo wotsatirawu:
Aluminiyamu aloyi ufa 85% ~ 88%;
Wopangira 12% -15%;
Momwemo, chopangira chopangiracho chimakhala ndi zigawo zotsatirazi:
Mwachiwonekedwe chimodzi, aluminium alloy powder ndi 2024 aluminium alloy powder.
Mwachiwonetsero chimodzi, aluminiyamu alloy 2024 aluminiyamu ufa uli ndi zigawo zotsatirazi ndi kuchuluka kwachulukidwe:
M'mawonekedwe amodzi, parafini yomwe ikufunsidwa ndi parafini No.58.
Mu mawonekedwe amodzi, kulemera kwa molekyulu ya ethylene-vinyl acetate copolymer kumayambira 1900 mpaka 2000.
M'modzi mwa ma embodiments, polyformaldehyde ndi co-polyformaldehyde.
Mu mawonekedwe amodzi, polyethylene glycol ndi polyethylene glycol 2000 mpaka 6000.
Kodi njira yokonzera chakudya cha aluminiyamu ndi chiyani, kuphatikiza njira zotsatirazi
- Preheat zotayidwa aloyi ufa kwa jekeseni akamaumba kudyetsa aliyense wa pamwamba 170 ℃ mpaka 190 ℃;
- Onjezani chopangira chilichonse chomwe chili pamwambapa aluminium aloyi jekeseni wopangira jekeseni ku preheated aluminiyamu aloyi ufa, pitirizani kutentha, ndi kusunga kutentha pa 175 ℃ mpaka 185 ℃ kusungunula wopangira ndikusakaniza ndi aluminiyumu aloyi ufa;
- Sungani kutentha kwa 175 ℃ mpaka 185 ℃ kwa mphindi 20 mpaka 30;
- Mtima pansi;
- Extrude;
- Dulani granulation chakudya.
Njira yopangira jekeseni ya aluminiyamu ya nkhunguzikuphatikizapo njira zotsatirazi: kuphatikizapo njira yokonzekera jakisoni akamaumba chakudya cha aluminiyamu aloyi monga tafotokozera pamwambapa ndipo, pambuyo kudula ndi pelleting chakudya, masitepe: kupanga, degreasing, ndi sintering.
Zomwe zimapangidwazo zikugwirizana ndi gawo lopangira jakisoni wa aluminiyumu yokonzedwa ndi njira yokonzekera mbali zonse za jekeseni wa aluminium alloy zomwe tazitchula pamwambapa.
Tatchulazi zotayidwa jekeseni akamaumba feedstock, zotayidwa aloyi jekeseni akamaumba mbali, ndi njira kukonzekera angagwiritsidwe ntchito kupanga zotheka zotayidwa mankhwala aloyi ndi nyumba zovuta, amene amasintha zophophonya miyambo zotayidwa aloyi processing mavuto, mkombero yaitali processing ndi mkulu processing mtengo, amachepetsa kwambiri kupanga ndi processing mtengo wa zovuta zotayidwa mbali zotayidwa kupanga mbali zonse zotayidwa aloyi kupanga. Zakweza mulingo waukadaulo waukadaulo ndi kupanga m'makampani opanga zoweta. Komanso, kudzera mu njira yatsopanoyi, njira yatsopano yokonzekera ndi kukonza, ubwino wa zida zopangira jekeseni wa aluminium aloyi ndi zabwino kwambiri, makamaka zoyenera kupanga zazikulu, kuchepetsa mtengo ndi kupititsa patsogolo mphamvu ya kupanga mbali zopangira aluminium.
Ubwino wa zitsulo zopangira jakisoni wa aluminiyamu ndi ziti?
· Mtengo
Zikafika popanga jekeseni, jekeseni wa aluminiyamu ndi wotsika mtengo kuposa jekeseni wachitsulo. Pongoganiza kuti zinthu zina zonse ndizofanana, nkhungu zopangidwa ndi aluminiyamu zimatha kubweza mtengo wandalama wa nkhungu mwachangu.
· Nthawi yopanga
Zoumba za aluminiyamu zimatsimikizira kupanga zinthu mwachangu. Kuchokera pakupanga nkhungu mpaka kumaliza kupanga, kuumba jekeseni wachitsulo kumatha kutenga miyezi 1-2. Komabe, ndi nkhungu za jekeseni wa aluminiyamu, kupanga nkhungu, ma prototypes ndi zinthu zomalizidwa kumatenga masiku 7-14 okha.
·Ndizothandiza pazochepa
Mitundu ya jekeseni ya pulasitiki ya aluminiyamu ndiyotsika mtengo kwambiri popanga magawo ang'onoang'ono. Izi ndichifukwa cha mtengo woyamba womwe adatha kuchepetsa, pomwe amangopanga magawo odalirika zikwizikwi.
· Nthawi yopuma
Zitsulo zachitsulo sizimataya kutentha msanga ngati zitsulo zopangidwa ndi aluminiyamu. Chifukwa chake, amatha kutentha ndikuzizira kwambiri mwachangu. Mu njira yopangira jakisoni, nthawi yoziziritsa imayang'anira kuzungulira kwa njira yonse yakuumba. Chifukwa chake, kusankha njira yopangira aluminiyamu kumatha kufupikitsa nthawi yozungulira ndikufulumizitsa gawo lopanga.
· Boutique
Kutentha kosagwirizana ndi kuziziritsa ndi chimodzi mwazinthu zomwe zimayambitsa zolakwika zina monga zipsera zakuya, voids ndi zipsera zoyaka. Kutentha kwapamwamba kwambiri kwa nkhungu za aluminiyumu kumapangitsa kuti nkhungu ikhale yotenthedwa ndi kuzizira mofulumira komanso mofanana, kuchepetsa chiwerengero cha ziwalo zolakwika ndi zidutswa.
·Kukonza Kosavuta ndi Kubwezanso
Kuuma kwachitsulo ndikwapamwamba kwambiri, kotero nthawi yokonzanso zowonongeka kapena zowonongeka zowonongeka zimakhala zazitali ndipo mtengo wokonza ndi wokwera, womwe umakhudza nthawi yobweretsera katundu. Komabe, nkhungu za jekeseni wa pulasitiki wa aluminiyumu zimapangidwa ndi zinthu zofewa, ndipo izi zimapangitsa kukonza ndikusintha kukhala kosavuta ngati pali vuto ndi nkhungu ya jekeseni ya aluminium.
