Processing Cost an overview ScienceDirect Topics

Processing costs (sometimes called operating costs) are the charges for use of the injection molding machine used to produce the part. They depend on the machine hourly rate, C h ($/hr), and the effective cycle time of the process, t eff.The effective cycle time is the machine cycle time, t, divided by the production yield, Y. Production yield, or just yield, is the fraction of the total parts
