The existing counter pressure casting machine has been modified to a new counter pressure casting machine with inclinable vaccum filling used for complicate light non ferrous castings. In fact

the new method intergrates all advantages of vaccum low pressure casting

conventional counter pressure casting and gravity casting. It is able to make the casting more compact

to reduce casting leakage under pressure test and to basically eliminate gas porosity and shrinkage cavity. As a result

material strength and toughness significantly improve.
