About Injection Molding Cooling Time Calculator (Formula)
The Injection Molding Cooling Time Calculator is used to estimate the cooling time required for an injection-molded part to solidify. The cooling time is a critical parameter in the manufacturing process as it affects the cycle time and quality of the final product. The formula used to calculate the injection molding cooling time is:
t = (h^2/(2pia)) * ln [ 4/pi * (Tm – Tmo) / (Teject – Tmo) ]
where:
- t is the cooling time in seconds.
- h is the part thickness in millimeters.
- a is the thermal diffusivity of the material in mm^2/s.
- Tm is the melt temperature of the material in degrees Celsius.
- Tmo is the mold temperature in degrees Celsius.
- Teject is the eject temperature in degrees Celsius.
This formula calculates the time required for heat to transfer from the molded part to the surroundings during the cooling phase of the injection molding process.
