Avoid Scale Buildup: The Silent Enemy of Cooling Performance
Obstructions in cooling can wreak havoc on molding. We recount our experience and offer tips on how you can keep things flowing.

Improve the Cooling Performance of Your Molds
Need to figure out your mold-cooling energy requirements for the various polymers you run? What about sizing cooling circuits so they provide adequate cooling capacity?

Balancing the Heat Budget in Injection Molds
Basic formulas for how much heat you must pull out of the mold to achieve a set cycle time.

Make Water Treatment Part of Your Process Cooling Program
Dirty, rusty, smelly water can wreak havoc with even the most meticulous process-cooling program.

Leverage Your Cooling Power
Injection molding is fundamentally a process that involves moving heat energy from place to place. Calculate heat transfer to maximize your cooling capacity.
