8.4.2 Design process

To obtain the critical slow plunger velocity, one has to follow this procedure:

1. Calculate/estimate the weight of the liquid metal.

2. Calculate the volume of the liquid metal (make sure that you use the liquid phase property and not the solid phase).

3. Calculate the percentage of filling in the shot sleeve, .

4. Find the number from Figure .

5. Use the number found to calculate the plunger velocity by using equation ().
