Often times when we hear that there is a random filling imbalance related to a random part quality issue, we are skeptical that the problem is truly “random”. A majority of molds that we are asked to look at often times have a pattern to the data, and therefore, a common root cause behind the associated problems. These patterns may be a result of either non-uniform shear heating variations or steel related issues that affect a certain set of cavities. In order to first determine if there is a pattern, we need to break down a mold into flow groups and regions. By determining flow groups in a mold, not only can a person more easily find the true imbalance but it is also easier to determine the source(s) of the imbalances.

TESTIMONIALS
“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.”

“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.”
