• MMoldings = Combined mass of molded parts
• Cp = Specific Heat of the material
Step 3 – Heat Removal Rate
• Nlines = The total number of independent
cooling lines there are in the mold
• tc = The cooling time required by the part
(Determined in step 1)
Step 4 – Coolant Volumetric Flow Rate
• ΔTMax,Coolant = Change in coolant
Temperature During Molding (1°C)
• ρCoolant = Density of coolant
• CP = Specific heat of coolant
Step 5 – Determine Cooling Line Diameter
• ρCoolant = Density of coolant
• VCoolant = Volumetric flow rate of coolant
• μCoolant = Viscosity of coolant
• ΔPline = Max pressure drop per line
(Usually equals half of the pump capacity)
