3. Screw Replacement Criteria

Replace screw components when:

• Flight tip wear >1mm (causes poor mixing and inconsistent output).
• Corrosion pitting >0.5mm deep (risk of material contamination and structural failure).
• Cracks in flights or core (safety hazard – risk of screw breakage during operation).
• Screw clearance >0.8mm (material backflow reduces extruder efficiency by >20%).
• Material degradation (MFR variation >10%) – indicates poor mixing due to worn flights.

Excellence offers a screw inspection service (on-site or lab-based) to assess wear and recommend replacement timing.
