Systematic experimental studies have been conducted on metal flow and heat transfer in the squeeze casting process. An integrated flow-heat transfer approach for the design of squeeze castings has been developed. The experimental work addresses die design and process optimization, including control parameters such as gate speed, shot velocity, pressure and its application time. Processing of metallic and particulate reinforced squeeze castings are being investigated, as well as their mechanical properties.
