The increase in effectivity of material processing with employment of liquid CO2 during aluminium die casting
Original language description
The article is focused on monitoring the cooling effect of the liquid CO2. This unconventional cooling system was used as a supplement method added to the standard tempering system of the die casting mould particularly intended for aluminium alloy castings. Standard tempering system of die casting moulds enables preheating the mould to operating temperature before the particular production starts and then the tempering system regulates the temperature balance between the mould and the casting during individu al production cycles. Conventional cooling system is based on drilled or milled interconnected channels with predominantly parallel orientation to the parting line, through which a tempering medium (oil, water etc.) flows. This system has some limitations that can be overcame with utilizing of special approaches. One of these approach is employment of liquid CO2. This study revealed the positive impact of this additive cooling on homogeneity of temperature field distribution on the mould cavity surface, which assures first of all the uniform coating the cavity surface by separating agent and sticking the melt on the cores. The products were analysed using the metallographic and CT analyses and the leak tightness was tested.
