Increasing the Reliability and Reducing the Cost of Base Members Made of Aluminum-Based Alloys

Abstract

In mechanical engineering, the processes of cast blank production compete with the processes of metal forming. This competition intensifies when comparing the properties of structural materials such as steel and aluminum-based alloys. Based on the results of research and a comparative analysis of various solutions, a technological scheme of horizontal plunger die-casting, free filling of the mold cavity with liquid metal, and the application of high pressure to the crystallizing metal is developed. The option of casting and applying pressure aimed at suppressing ring-shaped casting shrinkage is considered. The advantages and disadvantages are determined. The possibilities of expanding the scope of application are named. The requirements for the equipment design and for the control means, process regulation and control are determined.
