Drying time: Enter part weight, cold runner weight, cycle time, and number of cavities to get the plastic calculation to determine material processing time and dryer size.

Residence time: Enter your runner design, plastic part weight, cold runner weight, cycle time, number of cavities, and other parameters for the plastic calculation of shot utilization and weight, material processing time, hot runner residence, dryer size, total system residence time, and more.

Volume: Enter cycle time, parts made per cycle, efficiency rate, and production hours per day to determine the volume of plastic parts produced per minute, hour, day, week, month, and year.
