They may be degraded resin from a dead spot, carbonized contamination from the hot runner, foreign material from handling, damaged colorant, or particles released during a material change. Purging may remove the evidence temporarily without removing the source. Before purging: save the first and last affected parts, purge onto a clean metal surface, identify cavities, and note whether particles are embedded, smeared or sitting on the surface. That evidence can disappear once the machine is emptied.
