GRAVITY DIE CASTING
Gravity die casting is particularly economic in respect of the casting of high quantities. This casting method enables an adjustment of the mechanical values by the metallurgy. The higher solidification speed – compared with the speed of sand casting – normally leads to a denser structure and to a high level of dimensional stability.
The dense feeding, the fluidity and imaging process, i. e. whether every edge of the casting part is casted, in the gravity die can be influenced by thorough melt treatment and targeted coating with CILLOLIN.
Cleaning of non-metallic impurities and inclusions as well as to reduce the proportion of metal in the dross
Modification to achieve higher strength and extension values in the casting part
Grain refining to improve the feeding behaviour and prevent the formation of pores, shrinkage cavities, sinks and gas permeability.
