The paper presents the test results of a computerized control system the sequential cooling process of permanent mold with use of water mist in the gravity die casting process.
It describes the process for preparing high-quality casts made of AlSi7Mg alloy that achieves enhanced mechanical properties. A scheme of developed device and drivers for selected methods of sequence cooling for manufacturing of castings made in permanent steel mold was presented here. Also the microstructure and mechanical properties of received aluminium casts were described. It was shown that the use of a computer system to control the water mist cooling point of the mold not only accelerates the cooling of the cast and the gravity die casting cycle shortens, but also it has a positive effect on the microstructure and mechanical properties of castings made of unmodified AlSi7Mg alloy in a raw state.
