Die Casting

What Is The Process?

Explanation of the Die Casting process and why cooling is required.

  1. Die casting is very similar to injection moulding only its molten metal and not plastic that is injected into the mould
  2. There is still a hydraulic motor but not usually as large on injection moulding and mould cooling for the work piece

Die Casting Cooling

Why is cooling required for the die casting process?

  1. To cool the mould there are cooling pass-ways in the mould, cooling water flows around these pass ways to remove the heat from the product. This transfers the heat into the water requiring cooling
  2. The hydraulic oil is pumped around the system at high pressure for all the robotic parts on the machine. The hydraulic oil heats up when the hydraulic pump runs caused by the machine cycling. The hydraulic oil passes through a heat exchanger with water passing through the secondary circuit removing the heat from the oil

How To Calculate The Cooling

  • Tools = Material through put x (SHC of material x kg/hr x temperature difference) + Material through put x latent heat of solidification of material) = Cooling Duty in KW
  • Hydraulics = 400 kcals / 1 hour x hydraulic motor size / kcals = Cooling Duty in KW
