Abstract

Official abstract text for this publication.

A method for a die casting with a casting device which includes a casting valve with a valve piston and a post-compression piston configured to provide a post-compression. The method includes providing a casting valve in a closed position and a mold cavity which is cleaned and prepared for a mold filling process, opening the casting valve for a casting, filling the casting valve with a melt, closing the casting valve after the filling with the melt, cooling the casting valve and the melt, and removing a cast part. A post-compression is provided to the melt during the cooling by the post-compression piston.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for die casting with a casting device comprising a casting valve with a valve piston and a post-compression piston configured to provide a post-compression, the method comprising: providing a mold cavity which is cleaned and prepared for a mold filling process, and a casting valve in a closed position; opening the casting valve for casting; filling the mold cavity with a melt via the casting valve; closing the casting valve after the filling of the mold cavity with the melt; cooling the casting valve and the melt; removing a cast part; and providing a post-compression to the melt in the mold cavity during the cooling and before the removal of the cast part by the post-compression piston, wherein, the post-compression piston is integrated in the casting valve, and the post-compression piston travels beyond a front side of the valve piston into the mold cavity when providing the post-compression.
