RE: Wear Mechanisms on Injection Molding
There were a lot of work that could have been and needed to be done but we weren’t allowed to pursue. This was in a industrial setting. There should be a lot of information available on the net.
You might approach it thru the backdoor by starting with the steel producers and working forward. The extruder people have done a great deal of work with various components of and ancillary.

Literature on Injection molding.
RE: Wear Mechanisms on Injection Molding
Sliding
Impact or angular contact
Grinding
Each influenced by particle:
Size: wear is proportional to size
Shape: spheroid (glass bead) to flat (mica)to acicular (glass, carbon fibre,). Acicular and flat particles that tend to "log jam" can increase pressure and increase wear in one area yet reduce wear in another by layering.
Spheroid particles develop sharp jagged edges if they break when subjected to grinding.
Hardness: increases wear
Edge sharpness: increases wear
Pressure: increases wear
