OEM oanpaste aluminium alloy castings trochsân castingen shell mal casting prosessen.
Aluminium en syn alloys koe wurde getten en getten troch hege druk die casting, lege druk die casting, swiertekrêft casting, sân casting, ynvestearring casting enferlern foam casting. Meastal hawwe de aluminium alloy castings minder gewicht, mar komplekse strukturele en better oerflak.
Hokker aluminiumlegering wy cast troch sân castingproses:
• Cast Aluminium Alloy troch China Standard: ZL101, ZL102, ZL104
• Cast Aluminium Alloy troch USA Stardard: ASTM A356, ASTM A413, ASTM A360
• Cast Aluminium Alloy troch oare Starndards: AC3A, AC4A, AC4C, G-AlSi7Mg, G-Al12

Aluminium Alloy Castings Skaaimerken:
• De casting prestaasjes is fergelykber mei dy fan stielen castings, mar de relative meganyske eigenskippen ferminderje mear signifikant as de muorre dikte nimt ta
• De muorre dikte fan castings moat net wêze te grut, en oare strukturele funksjes binne fergelykber mei dy fan stielen castings
• Licht gewicht, mar kompleks struktureel
• De casting kosten per kg fan aluminium castings binne heger as dy fan izer en stiel castings.
• As produsearre troch die casting proses, de mal en patroan kosten soe wêze folle heger as oare casting prosessen. Dêrom, die casting aluminium castings soe mear geskikt foar castings fan grutte easken kwantiteit.
