A Study on Development Dosing System of Gating System for Semi-Solid Diecasting Process by Finite Element Method

유한요소해석을 이용한 반용융 다이캐스팅 공정의 주조방안 설계시스템 개발에 관한 연구

Semi-Solid Diecasters usually carry out the Semi-Solid diecasting experiments before producing new casts. At the Semi-Solid diecasting stages, the runner-gate part has been always repeatedly corrected, which leads to a tedious processing time and increased processing cost. A large amount of experience is essential in manual assessment and if the design is defective, much time and a great deal of efforts will be wasted in the modification of the die. In this study, design system has been developed based on design database. In addition, gate experiment for gating system design has been carried out to append the database. It is possible for engineers to make efficient gating system design of Semi-Solid diecasting and it will result in the reduction of expenses and time to be required. The detailed contents of the research are described in the followings. An attempt is made to link programs incorporating a number of expert design rules with the process variables obtained by commercial FVM softwares, MAGMAsoft, to form a useful package.
