Plastic cooling rate is one of the four basic plastic variables. Establishing accurate control is…
This month’s topic, in our SimTech™ series of webinars, reviews the causes and solutions to burn marks. Burn marks occur when plastic fills the cavity and air is pushed ahead of the flow front. If the air cannot escape fast enough, it is compressed by the incoming plastic. Compression of a gas raises its temperature, the temperature gets high enough to ignite the oxygen in the compressed air. This causes a charred or burnt appearance in the part. So how do you avoid this problem? In this webinar, our expert instructor will walk you through various scenarios, utilizing Paulson’s powerful injection molding machine simulator SimTech. You’ll get an inside look into the process from the “plastic’s point of view” as the foundation to all molding strategies. This means, understanding the concept that all machine controls affect one or more of the four plastic processing variables. Paulson’s entire approach, from starting up a machine for a production run, to problem solving an existing run is to examine the situation from the plastics point of view.

Special Guest: Donald C. Paulson
Newly inducted into the 2021 Plastics Hall of Fame, (read more here), Donald Paulson is the founder and chairman of Paulson Training Programs, Inc. and the creator of the now widely accepted method of teaching plastic processing from the “Plastics Point of View”. Don will join this webinar and give his personal account of his years of research with the General Motors Institute that lead to transforming injection molding from an art to a science. An experience you won’t want to miss.
