Sand Casting Product yopangidwa ndi Stainless Steel

Kuponyera mchenga kumagwiritsa ntchito mchenga wobiriwira (mchenga wonyowa) kapena mchenga wouma kupanga makina owumba. Thekuponya mchenga wobiriwirandi njira yakale kwambiri yoponyera zinthu yomwe imagwiritsidwa ntchito m'mbiri. Popanga nkhungu, mapangidwe opangidwa ndi matabwa kapena zitsulo ayenera kupangidwa kuti apange dzenje. Chitsulo chosungunulacho chimatsanulira mu mtsempha kuti apange zoponyera pambuyo pozizira ndi kulimba. Kuponya mchenga ndikotsika mtengo kuposa njira zina zopangira nkhungu komanso gawo loponyera ma unit. Mchenga kuponyera, nthawizonse zikutanthauza wobiriwira mchenga kuponyera (ngati palibe kufotokoza wapadera). Komabe, masiku ano, njira zina zoponyamo zimagwiritsanso ntchito mchenga kupanga nkhungu. Ali ndi mayina awoawo, mongachipolopolo nkhungu kuponyera, utomoni wa furan wokutira mchenga (palibe mtundu wophika),kutaya thovundi kuponya vacuum.

Tili ndi mitundu yosiyanasiyana yoponya yomwe mungasankhe. Chimodzi mwazinthu zomwe mungasankhire polojekiti yanu idzakhala kusankha njira yoponya yomwe ingakwaniritse zosowa zanu. Maonekedwe otchuka kwambiri ndi kuponya mchenga komwe kumaphatikizapo kupanga chithunzi cha chidutswa chomalizidwa (kapena chojambula) chomwe chimaponderezedwa ndi mchenga ndi zowonjezera zowonjezera kuti zipange kuponya komaliza. Chitsanzocho chimachotsedwa pambuyo pa nkhungu kapena zojambulajambula, ndipo zitsulo zimayambitsidwa kudzera mu dongosolo lothamanga kuti mudzaze patsekeke. Mchenga ndi zitsulo zimalekanitsidwa ndipo zotayira zimatsukidwa ndikumalizidwa kuti zitumizidwe kwa kasitomala.

Kuponya Mchenga VS Kuponya Mould Mold:
Kuponya mchenga ndi nkhungu zipolopolo zimagwiritsa ntchito mchenga kupanga dzenje lothiramo. Kusiyanitsa ndiko kuti kuponya mchenga kumagwiritsa ntchito mchenga wobiriwira kapena mchenga wouma (kutayika kwa thovu ndi kutayira kwa vacuum kumagwiritsa ntchito mchenga wowuma kuti apange nkhungu), pamene chipolopolo cha chipolopolo chimagwiritsa ntchito mchenga wokutidwa ndi utomoni kupanga makina opangira. Mchenga wokutidwa sunagwiritsidwenso ntchito. Komabe, mapangidwe a chipolopolo cha chipolopolo ali ndi khalidwe labwino kwambiri kuposa lamchenga castings.

Sand Casting VS Investment Casting:
Njira ziwiri zoponyera izi ndizosiyana ndi zida zomangira zomwe zimagwiritsidwa ntchito popanga mapatani.Investment castingamagwiritsa ntchito sera kupanga zofananira (ndicho chifukwa chake zimatchedwanso kuponya phula) zomwe zimakhala ndi kukula ndi miyeso yofanana ndi zoponyedwa zomwe zimafunidwa. Kenako phula lofananalo lidzakutidwa ndi mchenga ndi zomangira (nthawi zambiri silika sol kapena galasi lamadzi) kuti apange chipolopolo cholimba chachitsulo chosungunuka. Ngakhale, kuponya mchenga nthawi zambiri kumatenga mchenga wobiriwira kapena mchenga wouma kupanga dzenje, zomwe zimakhala ndi kukula ndi miyeso yofanana ndi zomwe zimafunidwa. Popanga mchenga ndi njira zopangira ndalama, mchenga ndi sera zitha kugwiritsidwanso ntchito. Zopangira ndalama nthawi zambiri zimakhala zolondola kwambiri kuposa kuyika mchenga.

Zololera zoponya zimagawidwa mu Dimensional Casting Tolerances (DCT) ndi Geometrical Casting Tolerances (GCT). Woyambitsa wathu akufuna kulankhula nanu ngati muli ndi pempho lapadera pazoyenera kulekerera. Apa m'munsimu muli kalasi yololera yomwe titha kufikira poponya mchenga wobiriwira, kuponyera nkhungu za zipolopolo ndi kuponyera mchenga wa furan resin:
✔ Gulu la DCT ndi Green Sand Casting: CTG10 ~ CTG13
✔ DCT Kalasi ndi Shell Mold Casting kapena Furan Resin Sand Casting: CTG8 ~ CTG12
✔ Gulu la GCT ndi Green Sand Casting: CTG6 ~ CTG8
✔ Gulu la GCT lopangidwa ndi Shell Mold Casting kapena Furan Resin Sand Casting: CTG4 ~ CTG7

Ubwino wa Njira Yoponyera Mchenga
1- Mtengo Wotsika chifukwa cha nkhungu zake zotsika mtengo komanso zobwezerezedwanso komanso zida zosavuta zopangira.
2- Kulemera kwa ma unit osiyanasiyana kuchokera ku 0.10 kg mpaka 500 kgs kapena kukulirapo.
3- Mapangidwe Osiyanasiyana kuchokera ku mtundu wosavuta kupita ku mtundu wovuta.
4- Yoyenera kupanga zofunikira zosiyanasiyana.
