There are many suppliers of hot runner systems with each offering different features based on the performance you want to achieve. We touched on this subject in a previous Tech Tip, however, not all topics could be covered in one tip. The purpose of this Tech Tip is to highlight the importance of an aggressive and diligent quality effort and how those checks can contribute to the operational performance, or lack thereof, of the hot runner system.
