Dew Point: Facts & Fallacies | Novatec All-In #106
Most plastics processors live by one number: -40 dew point.But a dryer reading -40 only tells you the dryer is working. It doesn't tell you the resin is dry.In Novatec All-In #106, Conrad Bessemer, Greg Washburn, and Tim Noggle are joined by the "Doctor of Drying," Mark Haney, and Joshua Belisle. They separate dew point fact from fallacy and explain what actually gets moisture out of the pellet.Topics discussed include:What dew point really measures, and what it doesn'tWhy -40 became the industry standardWhy chasing -60 or -100 can cost up to twice the energy with little benefitDry air vs. dry resin: the most common drying misconceptionHow hot air dryers evolved into desiccant dryers for engineering resinsWhat happens to nylon when it's under-dried or over-driedWhy temperature, delivered airflow, and time matter more than the dew point numberHow hopper geometry, elbows, and diffuser design affect air distributionA real customer case solved with ANSYS simulation and a redesigned diffuser bellThe episode also covers Novatec's focus on protecting resin value from receiving all the way to the press.Watch more episodes of Novatec All-In here:novatec.com/all-in#PlasticsProcessing #InjectionMolding #Extrusion #ResinDrying #DewPoint #PlasticManufacturing #ProcessEngineering
