How to Use This Calculator
- Enter fill time (sec), pack/hold time (sec), and cooling time (sec) from your process data.
- Set mold open/close time, ejection time, and any robot handling delay.
- Review total cycle time (sec), cycles per hour, and cycles per 8-hour shift.
- Check the cooling-time percentage — if above 60%, focus optimization on cooling circuit design.
- Use cycles-per-shift to calculate daily production volume for capacity planning.
