Molding rubber HYTREL with hot runner system
Has anyone experience to molding rubber HYTREL with hot runner system?
Do you have any suggestion?
i have worked as an application engineer for a German hotrunner company for several years and have plenty of experience with this material from that time, as well as from 6 years of self emplyment in application engineering and 3D simulation. Fee free contacting me at anytime.
Can you reveal what grade number we are talking about. We tried to work with some HYTREL but only as cold runner (two parts cavity) and we had some problems with filling of cavities if we didn't vent very well. There was also an issue with gate size that we had to adjust several times. It is not easiest material to play with.
