Cold Gun Cools Runner on Plastic Mold to Aid Part Removal

A plastic injection molder makes a certain part that has a "runner" left on it. When the part is pulled from the mold by a robot, it is still hot, and the runner simply stretches instead of pulling off of the part. EXAIR provided a Model 5315 Cold Gun Aircoolant System with two cold outlets to provide a blast of cold air, which cools the runner, and enables it to be removed cleanly.
