AI Technical Summary
Technical Problem
Existing casting methods, such as LPDC and gravity die casting, suffer from macro shrinkage porosities, particularly in areas where cross-section changes occur, leading to defects like shrinkage porosity in critical parts like wheels, which reduce mechanical strength and require long cycle times.
Method used
A hybrid casting process using a hybrid machine with a squeezing pin mechanism that applies mechanical force to compress excess metal in the last solidified area, combined with hydraulic control and filtration to prevent macro shrinkage and ensure defect-free production.
Benefits of technology
Enables production of robust, defect-free cast parts with high mechanical strength and reduced cycle times by preventing macro shrinkage and improving solidification control.

Abstract
The invention relates to the hybrid machine, which is used in the production of all cast parts, especially wheels, produced by using aluminum and other casting alloys with low pressure casting (LPDC) and gravity die casting methods, and which prevents the formation of macro shrinkage and ensures production with low scrap, robust and defect free, high material mechanical strength and low cycle times.
