โฆ Synopsis
This invention relates to seals for rotor sealing systems, particularly seals for machines that manipulate a hot, viscous material such as injection moulding machines. It is designed to overcome problems of polymer leakage and poor temperature distribution in the area of the seal. The detail of the seal is not very obvious.
