cycle time of a part in injection molding process is very importantas the rate of production and quality of the products manufactured depends on it. Cycle time is the total time from beginning to the end of the process. Cycle time includes process time. During which a unit is acted upon to bring it closer to an output, and delay time, during which a unit of work is spend waiting to take the next action.Decreasing the cycle time of a process increases the manufacturing capability in both quality and quantity.This can be achieved through various techniques like external cooling, improve capacity of cooling tower, Install Flow Meters, Proper design of the cooling channel, Optimization Of Injection Molding Machine Parameters like Cooling Time, Back Pressure And Plasticizing Limit, Optimum Height for Counter Flow Cooling Tower.Any manufacturing activity would like to have optimized productivity and quality. In injection moulding of plastics, if quality is taken care of by part design, mould design and mould precision, then productivity is also ensured on account of zero defect moulding without rejection and optimised cycle time.Cycle-time optimization starts at design stage. Cooling time takes up over 50% of cycle time. Therefore understanding of cooling in the mould becomes very important.
