3 Pressure – flasks casting

4  Castings is made without permanent models – as follows:  Pressure casting  Casting into ingot mould  Centrifugal casting  Continuous casting

5  Machine for pressure casting

6  Shaping block : Copping plate

7  1.Pressure casting  In pressure casting is melted steel pressured with a great speed into two or multiple moulds system.  High pressure ensures the best penetration of the melted steel into complicated forms of thin-walled moulds  Melted metal is piston ejected from pressure chamber.  Ejection is provided by two methods:  - from hot chamber  - from cold chamber

8  Casting from hot chamber – the chamber is submerged in melted metal.  It is used for casting of zinc, lead and magnesium alloys (metals with lower melting point than steel).

9  Melted metal poured into cold chamber and ejected by piston into a mould.  It is used for casting of copper and aluminum alloys. If hot chamber would be used the melted alloys would react with steel walls of chamber and piston.

10  Explain technology:
