Gravity fed casting
WebOne of the very important elements involved in the process is the geometry of the cast part and its relation to the placement of the parting lines. Parting Lines Die cast engineers will know that the dies must be made in a minimum of two parts. WebHydrogen precipitation may alter the form and distribution of shrinkage porosity in poorly fed parts or part sections. Shrinkage is generally more harmful to casting properties. In isolated cases, hydrogen may actually be intentionally introduced and controlled in specific concentrations compatible with the application requirements of the ...
