Build a maintenance program that reduces black specks by checking screw, barrel, non-return valve, nozzle, dead spots, wear, purge and verification.
Prevent black specks before molding with controls for resin storage, drying, purging, hopper cleanliness, startup, dead spots, regrind and inspection.
Diagnose black specks in molded parts by separating contamination, degraded resin, carbonized residue, colorant and mold or equipment sources with evidence.
