Injection cycle time
Webb9 okt. 2024 · Pack/Hold Time: 8.0 seconds at 4,150 PSIp. Cooling Time: 10.0 seconds. Overall Cycle Time: 21.43 seconds. If we add the process times together and divide by the overall cycle time, we reach a value of 0.85. That means that 85 percent of the cycle is spent cooling the part so that it can withstand the forces of ejection.
