Heating and Cooling the Moulds

Included Topics:

• Ratio Q/V of the supplied heat quantity Q and the volume V of the melt depending on the die casting alloy and demoulding temperature
• Orientation values for the cycle time depending on the nominal mould closing force of the die casting machine with horizontal cold chamber
• Physical properties of heat transfer fluids at a pressure of 1 bar depending on the temperature
• Heat transfer coefficient of the heat transfer fluids dependingbon the flow rate and average temperature of the heat transfer fluid
• Empirical values for temperatures of castings made of aluminium and magnesium die casting alloys [
• Arrangement and dimensions of heating and cooling ducts
• Temperature distributions at various distances from the mould engraving during a casting cycle for plates with the dimensions 200×75×20 mm made of GD-AlSi9Cu3 die casting allo
