A molded plastic part is heated enough to permit sufficient movement of the polymer molecules which allows relaxation. This can reduce stress within the part and when combined with fixturing, can also be used to reduce/eliminate excessive warpage.
“Of all the training seminars that I have attended over the past 10 years, this one ranks at the top! The explanations of clamp tonnage, cooling strategies, viscosity, and key mold design components are just a few of the takeaways that will be very useful in my job function.”
Russ Wolff, Business Development Manager
“I was amazed at the amount of expertise and knowledge presented in just two days. Many myths were debunked, numerous scientific explanations for the way we should be thinking about plastic flow were given, and various real-world examples were used to show how plastic flows.”
Don Makowski, Design Engineer
