Pressure flasks casting

Pressure – flasks casting


Casting with permanent moulds

Casting with permanent moulds

  • Castings is made without permanent models – as follows:

  • Pressure casting

  • Casting into ingot mould

  • Centrifugal casting

  • Continuous casting


Casting to permanent moulds

Casting to permanent moulds

  • Machine for pressure casting


Casting with permanent moulds1

Casting with permanent moulds

  • Shaping block : Copping plate


Casting with permanent moulds2

Casting with permanent moulds

  • 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


Casting with permanent moulds3

Casting with permanent moulds

  • 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).


Casting with permanent moulds4

Casting with permanent moulds

  • 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.
