The Tru-Filter plug consists of blind holes with melt entering from screw end and additional blind holes with melt exiting to mould (or nozzle orifice). A 0.38mm clearance space, between nozzle I.D. and plug O.D., provides filtering action to prevent contaminants from reaching the moulded part.
- Easily removed (and replaced) for cleaning.
- Excellent filtering for particles greater than 0.38mm
- Extended filter area provides long operation cyles before removal and cleaning are required.
- Provides additional benefit of significant mixing of melt stream with minimum back-pressure
