The time it takes to make a product using injection molding can be calculated:
Total time = 2M + T + C + E
Where:
(2M) = Twice the Mold Open/Close Time
(T) = Injection Time (S/F)
(C) = Cooling Time
(E) = Ejection Time (E)
(S) = Mold Size (in3)
(F) = Flow Rate (in3/min)
The total cycle time can be calculated using tcycle = tclosing + tcooling + tejection
The closing and ejection times of injection molded parts can last from a fraction of a second to a few minutes, depending on the size of the mold and machine. The cooling times, which dominate the process, depend on the maximum thickness of the part.
