This comprehensive 2-day class is for designers, mold builders, tooling engineers, and mold technicians who want to better understand and control the effects of mold cooling resulting in a more robust mold design, mold build, and molding process.
Find the flow rate where your cooling water makes the biggest impact on heat transfer. Enter your water temperature, percent of Ethylene Glycol, cooling circuit shape and size. The calculator will show you the flow rate needed to achieve your desired Reynolds Number.
Read the User Guidelines to find out how the Reynolds Number is calculated and how it applies to injection molding.
Find the cooling water flow rate and the length of cooling circuit required to transfer heat away from common polymers to achieve ejection temperature. Enter your polymer type from our dropdown list, cycle time, shot weight and molding room temperature. Other parameters used are: Reynolds Number, water temperature, differential temperature and cooling circuit diameter. Change the variables to see the results. Do they match your expectations?
