Description

High pressure die cast deep skirt block

The very fast filling of the mould in the HPDC process allows the realisation of extremely thinwalled, shell-like structures. Therefore high pressure die cast engine blocks are generally somewhat lighter than engine blocks produced by other casting techniques. The rigidity deficits of aluminium are compensated by conspicuous ribs, cambering and preferably
closed-profile elements.

Low pressure die casting ( LPDC)

Low pressure die casting is characterised by slow mould filling and solidification under pressure with the solidification front moving from the most distant point of the casting to the heated gate. Thus the resulting quality of the cast components excels that of parts produced by other casting processes.

Specific advantages of the LPDC process for the production of aluminium blocks for high performance engines are:

1.The use of sand cores, e.g. for water jackets, enables the production of structurally
rigid closed deck cylinder blocks.

2.Low turbulence die filling and controlled cooling of the die ensures componentspecific, directional solidification and thus a uniform microstructure, low porosity and minimum casting defects.

3. The possibility of a controlled cooling or local chilling of the engine block from the casting temperature and unrestricted subsequent heat treatments of the casting allow an enhancement of hardness and strength, but also a volume stabilization of the engine block (i.e. avoid an irreversible distortion when the casting is exposed to the operating temperature of the engine).

The LPDC process is closely linked to the ALUSIL® concept which has been developed by KS Aluminium-Technologie AG. The ALUSIL® technology is unique as it produces monolithic aluminium blocks without the need for an additional reinforcement of the cylinder bores. An further benefit of the ALUSIL® alloy AlSi17Cu4Mg compared to the standard hypoeutectic AlSi engine block alloys is a better structural rigidity due to the 12% higher Young’s modulus.

ALUSIL® cylinder blocks in V arrangement apply the principle of controlled solidification directed vertically downwards towards the bearing seat or skirt/side wall areas.
