压铸模与铝合金铸件间的焊合现象

Soldering between Die-Casting Die and Aluminum Alloy Casting

铝合金压铸焊合现象可分为化学反应焊合及机械焊合,铝熔体与模具基体接触后产生的物理化学反应是焊合产生的重要原因,通过合理选择压铸合金化学成分,控制压铸工艺参数,模具表面处理等手段可以减少焊合现象的产生。

Soldering between die-casting die and aluminum alloy casting can be classified as chemical reaction soldering and mechanical soldering. The physicochemical reaction between aluminum melt and die base is the important cause of soldering. By reasonable selection of casting alloy chemical composition, die casting technology parameters can be controlled and soldering phenomenon can be reduced by die surface treatment.
