AI Technical Summary
Technical Problem
Existing pressure casting methods for ceramic articles struggle to form undercut portions due to deformability issues, leading to damage or the need for separate bonding, which complicates the manufacturing process and reduces product quality.
Method used
A casting apparatus and method that uses a support frame with movable mould parts and passive inserts to form undercut zones, allowing automatic positioning and release of inserts during the casting process, eliminating the need for complex support devices and reducing hydraulic complexity.
Benefits of technology
Enables the production of complex ceramic shapes with high quality and efficiency by simplifying the manufacturing process, reducing costs, and enhancing productivity while maintaining product integrity.

Abstract
Casting method and apparatus (1) for manufacturing ceramic articles (2), the apparatus (1) comprising: - a mould (3) which, in turn, comprises: at least two mould parts (4A, 4B, 4C or 4A, 4B, 4C, 4D and 4E) mutually movable between a closed configuration, in which they are coupled to one another to define a casting cavity (5) and an open configuration; and at least one insert (6), adapted to cooperate with said at least two mould parts to create at least one undercut zone (P) in the ceramic article (2); - a feeding system to feed a mixture under pressure into said casting cavity (5); - a moving device (9) for automatically positioning the insert (6) in coupling with at least one of said two mould parts, when they are in the open configuration; and - a hydraulic system operatively connected exclusively to the at least two mould parts so as to feed a fluid under pressure through them.
