As the representative of the research and production facilities

As the representative of the United States Bureau of Mines research and production facilities for titanium investment casting technology in-depth research, development of the melting and casting process is suitable for titanium , which is a low-cost processing and forming of Titanium alloy valve opened up a new path. As a method of casting forming complex shapes can be directly manufactured parts eliminates a lot of the subsequent processing steps , thus increasing material utilization and reduce titanium alloy casting manufacturing costs.Titanium alloy valve in the aerospace engine usage and comparison of forgings , can be seen, Titanium alloy valve with clear growth trend will gradually reach the amount of titanium forgings for each equivalent level. In particular, the application of cast titanium valve in civilian areas , for example, if the casting can be mass produced with great golf club head , which promote the use and development of cast itanium alloy valve. In all system shell process parameters on shell quality and ultimately a greater impact on the quality of castings are: batter ingredients, namely powder -liquid ratio , dewaxing and roasting process parameters, this research labs now there are devices on the above parameters in-depth study and optimize selection.
