Artificial balancing is the practice of restricting and/or enhancing plastic flow to one or more cavities in order to have all the cavities in the mold fill at the same time. The methods most commonly employed in cold runner molds include changing gate diameters and/or runner diameters. When restricting flow in the runner system it is unfortunately too common to see people using restrictive pins, set screws, or other items that protrude into the runner system (Figure 1). In hot runner molds, adjusting the nozzle or tip temperature is the most common practice.

REVOLUTIONIZING INJECTION MOLDING
“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
