DIE DESIGNING AND MOLTEN METAL FLOW ANALYSIS FOR PARKING BRAKE PISTON

Die casting is a versatile process for producing engineered metal parts by forcing molten metal under high pressure into reusable steel molds. These molds, called dies, can be designed to produce complex shapes with a high degree of accuracy and repeatability. Parts can be sharply defined, with smooth or textured surfaces, and are suitable for a wide variety of attractive and serviceable finishes. The common defects found in these defective castings were categorized as follows: porosity, hot spot,cold laps, flow lines, aluminum oxide inclusions, lubricant or mold coating inclusions, and mechanical cracks.
