OEM Kev Cai Grey Hlau Casting
Product Description
Grey hlau, los yog grey cam khwb cia hlau, yog ib yam khoom ntawm cam khwb cia hlau nrog graphitic microstructure.Peb hu cov khoom siv no grey hlau vim yog xim grey ntawm pob txha.Rau cov graphite lubricating qhov txiav thiab rhuav tshem cov chips, grey hlau yog ib hom cam khwb cia hlau vim nws tus nqi qis thiab zoo machinability.Tsis tas li ntawd, vim cov graphite flakes nws tus kheej lubricate, nws kuj muaj zoo galling thiab hnav tsis kam.
Grey hlau kuj muaj tsawg zog shrinkage dua li lwm yam cam khwb cia hlau vim graphite microstructure.Thaum casting, cov khoom silicon tuaj yeem txhawb kev txhim kho corrosion zoo thiab ua kom muaj dej ntau ntxiv thaum casting.Grey hlau feem ntau suav hais tias yooj yim rau vuam.Piv rau lwm tushlau castings, grey hlau muaj lub zog tensile thiab ductility;Yog vim li cas qhov cuam tshuam thiab poob siab tsis kam ntawm cov khoom siv no yuav luag tsis muaj nyob.

Hauv peb qhov chaw tsim khoom, peb tuaj yeem ua grey hlau castings hauv qab ob hom:
Poob Foam Casting: Ib leegpeev castingtxheej txheem rau cam khwb cia hlau Cheebtsam, uas muaj ntau yam zoo los tsim me me grey hlau investment castings, xws li txuag pwm nqi, shorten ntau lawm voj voog thiab txhim kho ntau lawm efficiency.Nrog cov txheej txheem ua npuas dej ploj, peb tuaj yeem pab peb cov neeg siv khoom kom tau txais cov khoom raug siab nrog kev ua tiav zoo heev, thiab kev ua haujlwm tsawg dua yuav ua tiav.
Resin Sand Casting: Lub ntsiab xuab zeb casting txheej txheem rau me me thiab nruab nrab castings.Piv nrog rau lwm cov txheej txheem xuab zeb casting, resin xuab zeb casting yog qhov tseeb casting txoj kev ze rau peev casting.Raws li zoo rigidity ntawm resin xuab zeb thiab siab zog ntawm xuab zeb pwm thaum ntxov casting, ces peb yuav zoo tshem tawm cov shrinkage kab noj hniav, shrinkage defects ntawm grey hlau castings.
