Tuam Tshoj OEM kev cai ductile cam khwb cia hlaupoob ua npuas ncauj casting khoomrau tsheb spare qhov chaw.
Poob Foam Casting, tseem hu ua Lost Foam Casting (LFC) lossis Puv Pwm Casting, yog ib hom Evaporative Pattern Casting (EPC) nrog cov txheej txheem xuab zeb qhuav. EPC qee zaum tuaj yeem luv luv rau Expendable Pattern Casting vim tias cov qauv ua npuas ploj tuaj yeem siv ib zaug xwb. Tom qab cov qauv ua npuas ncauj tiav los ntawm cov tshuab tshwj xeeb, tom qab ntawd cov qauv yas foamed yog coated nrog refractory txheej los ua lub plhaub muaj zog kom tiv taus cov hlau molten. Cov qauv ua npuas ncauj nrog cov plhaub tau muab tso rau hauv lub thawv xuab zeb, thiab sau nrog cov xuab zeb qhuav nyob ib ncig ntawm lawv. Thaum lub sij hawm pouring, lub high-temperature molten hlau ua rau cov ua npuas ncauj qauv pyrolyzed thiab "poob" thiab occupies lub tawm kab noj hniav ntawm cov qauv, thiab thaum kawg cov tiav lawm xav castings yog tau.
Cov kauj ruam ntawm Poob Foam Casting:
1- Siv cov pwm ua npuas ncauj los tsim cov qauv ua npuas ncauj thiab cov txheej txheem casting
2-Txhim kho cov qauv thiab cov neeg khiav dej num los tsim cov pwm pwm
3- Dip xim rau ntawm lub module
4- Qhuav cov xim
5- Muab lub module tso rau hauv lub thawv xuab zeb thiab sau nrog cov xuab zeb qhuav
6- Vibrate molding thiaj li yuav sau cov kab noj hniav nrog cov xuab zeb qhuav thiab tom qab ntawd compact cov xuab zeb molding
7- Pouring molten hlau kom vaporize ua npuas ncauj thiab tom qab ntawd tsim cov yam xav tau
8- Tom qab cov castings tau txias lawm, ntxuav cov castings. Cov xuab zeb qhuav tuaj yeem rov ua dua
Hlau thiab Alloys Casting Lost Foam Casting Txheej Txheem:
• Grey Cam khwb cia hlau, Ductile cam khwb cia hlau
• Carbon Steel: Tsawg carbon, nruab nrab carbon thiab siab carbon steel
• Cast Steel Alloys: Tsawg alloy steel, siab alloy steel, tshwj xeeb alloy steel
• Aluminium thiab lawv cov alloys
• tooj dag & tooj liab.
Kev lag luam yog Cov Poob Foam Castings siv rau:
Raws li tau hais los saum toj no, qhov poob ua npuas ncauj casting yog tshwj xeeb tsim los tsim cov loj thiab tuab-wall castings. Lawv tau ua haujlwm feem ntau ntawm cov tshuab hnyav nrog cov kev xav tau ntawm cov qauv ntawm cov yam xav tau castings xws litsheb thauj khoom, tsheb laij teb, tsheb ciav hlau, kev tsim kho tshuab ... thiab lwm yam.
Casting Tolerances ncav cuag Lost Foam Casting txheej txheem:
Feem ntau hais lus, qhov kev ua siab ntev ntawm kev poob ua npuas ncauj yog qhov zoo duaxuab zeb casting, tab sis phem duaplhaub moldingthiab tsis muaj ci casting txheej txheem. Rau peb cov foundry, peb yeej tuaj yeem ua tiav cov qib casting nram qab no. Tab sis peb xav nrog koj tham txog qhov tshwj xeeb castings thiab tom qab ntawd txiav txim siab seb tus lej twg peb tuaj yeem muab rau koj.
