Injection Molding Accessories

Find the cooling water flow rate and the length of the 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?

Find the flow rate where your cooling water makes the biggest impact on heat transfer. Enter your water temperature, percentage of Ethylene Glycol, cooling circuit shape, and size.

The calculator determines the flow rate needed to achieve your desired Reynolds Number. Read the User Guidelines to learn how the Reynolds Number is calculated and how it applies to injection molding.

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.

After successful class completion with a minimum test score of 70%, you will earn a Scientific Cooling Certificate. You will have the tools to implement Scientific Cooling principles in your molding process.

Compiled after many years of research, our list of technical articles related to injection mold cooling and water quality can help in your journey to more efficient molding.

The Tools section contains references including our Turbulent Flow Reference Chart, Quick Mold Change Guide, Expected Rate of Flow Chart, and more.
