Die Casting Fluidity

Fluidity refers to the ability of an alloy liquid to fill a mold. The amount of fluidity determines whether the alloy can cast complex castings. The eutectic alloy has the best fluidity in aluminum alloys.
There are many factors affecting the fluidity, mainly the solid particles of the composition, temperature and metal oxides, metal compounds and other pollutants in the alloy liquid, but the external fundamental factors are the pouring temperature and the pouring pressure (commonly known as pouring indenter). High and low.
In actual production, in addition to the smelting process (refining and slag removal), the mold processability (sand mold permeability, metal mold venting and temperature) must be improved without affecting the alloy. Increasing the pouring temperature under the premise of casting quality to ensure the fluidity of the alloy.
