Hi everybody. We are having a challenge with some of our machines when we use mucel. Mucel is nitrogen injected into the barrel and then into the part to create Hollow parts so to speak. Not sure if mucel is the proper word. Three zones In The barrel continuously rise in temperature around 300 degrees Celsius. The set points are around 240. We have to alter the set points to keep the machine running. We are all new to this type of molding, any suggestions? We are running poly pro with regrind in it. 10% regrind. Thank you in advance for any help you may offer.
