Zaka 20+ zamakampani, kupereka ntchito za OEM/ODM zamtundu wapadziko lonse lapansi wa mowa ndi zakumwa.

Kusindikiza Kwapamwamba | Zakudya Zopangira Zakudya | Full Can Type Support | Global Export

Gawo 1: Chifukwa chiyani 3104 Aluminium Alloy ndi Ngwazi Yosasunthika ya Zitini Zakumwa?

Chitini chosalala, chopepuka cha aluminiyamu chomwe chili m'manja mwanu sichimangotengera chidebe chachitsulo—ndi luso lodabwitsa la umisiri wa zinthu. Chigawo chake chachikulu ndi 3104 Aluminium Alloy , chinthu chosankhidwa mwapadera chomwe chimapangitsa kuti chakumwa chamakono chitheke.

Vuto: Bwanji Osangogwiritsa Ntchito Aluminiyamu Yoyera?

Kuti akwaniritse zofuna zamakampani opanga zakumwa zothamanga kwambiri, akhoza kukwaniritsa zolinga zinayi zotsutsana:

1. Yopepuka koma Yamphamvu: Iyenera kukhala yosavuta kunyamula koma yolimba mokwanira kuti ingasungidwe.

2. Yopangidwa ndi Ductile: Ayenera kupitilira njira zingapo zotambasula/zojambula popanda kusweka.

3. Zosalimbana ndi Pressure: Ziyenera kukhala ndi mphamvu yamkati yazakumwa zoziziritsa kukhosi (CSDs) ndi mowa.

4. Kupanga Mwachangu: Ayenera kupangidwa mothamanga kwambiri kuposa zitini 2,000 pamphindi.

Aluminiyamu yoyera sangathe kukwaniritsa zofunikira zapangidwe ndi kupanga.

Yankho: Sayansi ya 3104 Alloy

Aloyi ya 3104 imakwaniritsa zinthu zake zapamwamba kudzera muzowonjezera zenizeni za zinthu zofunika:

Alloying Element	Maperesenti Range	Ubwino Woyambirira
Magnesium (Mg)	2.3–3.0%	Imawonjezera mphamvu komanso kulimbitsa mphamvu.
Manganese (Mn)	0.9–1.5%	Imawonjezera Ductility (kutambasula) ndi kukana dzimbiri.

Kapangidwe kameneka kamapereka kuthekera kwapadera , kulola chimbale chokhuthala cha aluminiyamu, chotchedwa Can Body Stock (CBS) , kuti chiwonjezeke mu thupi lochepa kwambiri (lotchedwa Drawn and Wall Ironed or DWI process).

Mwachidule: 3104 Aluminiyamu Aloyi = Opepuka + Mphamvu Yapamwamba + Chitetezo cha Chakudya + Chokhazikika Chopanda Malire.

Gawo 2: Kupitilira Pamwamba - Zigawo Zitatu Zapakati pa Chitini cha Aluminium

Chidole chowoneka chosavuta kwenikweni chimakhala chophatikiza chazinthu zitatu zovuta, zopangidwa mwapadera, chilichonse chopangidwa kuchokera kuzinthu zosiyanasiyana komanso njira.

1. Thupi la Can (Chipolopolo) 

Thupi limapangidwa kuchokera ku koyilo ya aluminiyamu kupyola magawo angapo ojambulira ndi kusita pakhoma, kusintha chitsulo chopanda kanthu kuchokera pa makulidwe oyamba a 0.28mm mpaka kukhuthala komaliza kwa khoma la 0.09-0.11mm..

• Dome Base: Pansi pake amatambasulidwa kukhala mawonekedwe opindika kuti awonjezere mphamvu yake yolimbana ndi kukakamizidwa kwamkati.

• Necking: Mphepete mwapamwamba imachepetsedwa pang'onopang'ono ( khosi ) kuti muvomereze chivindikiro chocheperako.

Kuzindikira kwa Katswiri: Ukadaulo wothamanga kwambiri (DWI) womwe umagwiritsidwa ntchito popanga izi ndi mwini wake ndipo umayendetsedwa ndi mayiko ochepa komanso opanga zazikulu padziko lonse lapansi, kutsimikizira chotchinga chake chaukadaulo.

2. The Itha Kutha/Lid (Chisindikizo Chakukakamiza) 

Chivundikirocho ndicho mbali yofunika kwambiri mwaukadaulo—ndipo kaŵirikaŵiri ndiyo yodula—mbali ya chitinicho. Zapangidwa kuti zikhale chipangizo chomaliza chosindikizira.

• Zakuthupi: Zimasindikizidwa kuchokera ku Can End Stock (CES) , nthawi zambiri 5182 high-strength aluminium alloy.

• Ntchito Yosindikiza: Iyenera kusunga chisindikizo chabwino kuti chiteteze kutayikira komanso kutayika kwamphamvu.

• Njira Yotsegulira: Pamafunika kugoletsa ndendende, mzere wopyapyala ( mphambu ) ndi yopindika bwino tabu kuti muwonetsetse kutsegulira kosalala, koma kotetezeka.

Chivundikirocho chimafuna aloyi wapamwamba kwambiri (5182) chifukwa chimayenera kupirira kugwedezeka kwa kutseguka pomwe ndichofunikira kwambiri kukana kukanikiza.

3. The Food-Grade Internal Coating (Chotchinga) 

Kuteteza onse ogula ndi malonda, khoma lamkati la chitini limapoperapo ndi nsalu yapadera, yopyapyala kwambiri ya BPA-Non-Intent (BPA-NI) ya chakudya (nthawi zambiri zosakwana $10 ext{micrometers}$).

• Kuteteza Kudzimbiri: Chotchinga ichi chimalepheretsa chakumwa (makamaka zakumwa za acidic monga soda kapena timadziti ta zipatso) kuti zisawononge aluminiyumuyo.

• Imasunga Kukoma: Imalepheretsa kununkhira kwachitsulo cha aluminiyamu kuti chisalowe ndi kuipitsira chakumwacho.

• Imawonetsetsa Moyo Wa Shelufu: Chophimba chokhazikika komanso chokhazikika ndichofunikira kuti chinthucho chikhale ndi nthawi yayitali ya alumali.

Kuyikira Kwambiri: Kusasinthika ndi kukhazikika kwa chiwombankhanga chamkati sichingakambirane, kumakhudza mwachindunji mbiri yamtundu komanso kukoma ndi kusungidwa kwa chinthu chomaliza.

Gawo 3: Gwero - Kuchokera ku Aluminium Ingot kupita ku Can Stock Coil

Nthawi ya moyo wa chitini simayambira pafakitale yopanga zitini. Zimayamba kale kwambiri, ndi zopangira zopangira:

The Can Stock Manufacturing Process:

1. Kusungunuka kwa Ingot: Ingots zoyambira za aluminiyamu zimasungunukanso ndikusinthidwa kukhala homogenized.

2. Kuponya Mosalekeza: Aluminiyamu yosungunuka imaponyedwa mosalekeza m'mbale zazikulu kapena mbale.

3. Cold Rolling: Ma mbale awa amadutsa magawo angapo ozizira ozizira kuti achepetse makulidwe ake.

4. Final Gauge: Zinthuzo zimayikidwa ndendende ku makulidwe a thupi, nthawi zambiri 0.25-0.31mm.

5. Kutsiliza: Pamwamba pake amasanjidwa, kudula, ndikumangidwa mwamphamvu m'makoyilo akuluakulu ( Can Stock ), okonzeka kutumizidwa kumalo opangira zitini.

Chilichonse pakuchita izi ndi chofunikira kwambiri, kutsimikizira mphamvu yomaliza ya chitini, kukhazikika kwapangidwe, ndi kuchuluka kwa zokolola. Kulondola kwapamwambaku ndichifukwa chake mabungwe akulu okha, apadera a aluminiyamu (monga Novelis, Constellium, ndi UACJ) ndi omwe amatha kugulitsa chakumwa chapadziko lonse lapansi.

Chotsatira Ndi Chiyani? Ulendo wa Can's Kupyolera Pansi Pafakitale

Mgawo lotsatira la [ Jinzhou Packaging · Aluminium Can Life Cycle Series] , tidzalondolera ulendo wa koyilo ya Can Stock pamene imasinthidwa kukhala chitini chomalizidwa, chosindikizidwa, ndi chokonzekera kudzaza!

Tidzakambirana za ukadaulo wa:

• Cup Pressing

• Kujambula & Kusita Pakhoma (DWI)

• Kupanga Base (Doming)

• Kuchepetsa

• Kuchapa ndi Kuyanika

• Kusindikiza Kwamitundu Yothamanga Kwambiri 6–8

• Kuchiritsa kwamkati kwamkati

• Kuyang'ana kwa Necking ndi Masomphenya

Izi zidzakuthandizani kumvetsetsa: Chifukwa chiyani aluminiyamu imatha kukhala yotsika mtengo komanso yapamwamba kwambiri?
