How to Use This Calculator
- Enter wall thickness (mm) — the thickest cross-section of the part controls cooling time.
- Set melt temperature (°C) and mold temperature (°C) for your material and process.
- Enter ejection temperature (°C) — the temperature at which the part is stiff enough to eject.
- Review calculated cooling time (sec), and how it varies with wall thickness.
- Cooling typically represents 50–70% of total cycle time — minimize it by reducing wall thickness.
