Shot Optimization

Technoloies

      In the High-Pressure Die Casting (HPDC) process, the pre-injection displacement of the plunger significantly influences the interplay between atmospheric air, liquid aluminum, and the molten metal within the cavity. In an inadequately optimized shot profile, the oscillation of liquid aluminum induces a commingling of air and molten aluminum. The resultant fluctuation in aluminum melt, contingent upon its specific shape, alters the proportion of entrained air, thereby precipitating air entrapment, porosity, and the formation of high-pressure micro-porosity in the solidified product. This, in turn, diminishes the mechanical properties of the final product.

 

   The lower mechanical properties of the final product can be attributed to the formation of undesirable AL-203 microparticles, a consequence of increased chemical interaction surface in the aluminum melt's air bubble. Utilizing the SDS concept, the die system's shot profile can be enhanced through the FLOW3D simulation program, tailored to the customer's die casting machine. This optimization facilitates the production of more intricate components with the desired mechanical properties.
