Multipoint Rapid Metal Forming Technology Based on Micro-Fluid Control
Based on micro-fluid control, a rapid metal forming method with high efficiency is proposed. At first, the basic principal is introduced. The metal liquid flows out of a large number of micro-pores, and the multipoint parallel crystallization is thus realized. During the forming process, the open or close of micro-pores is controlled by surface tension to obtain required shape of part. Then the technological parameters are deduced. Preliminary experiment shows that rapid open and close of micro-pore can be realized acted on surface tension. This method has the basic characteristics of rapid prototyping technology and continuous casting technology, which can overcome the shortcomings of inefficient and difficulty to create high melting point metal parts for current rapid prototyping.
