2. CNC machining with real-time dimensional monitoring.
3. Heat treatment (quenching/tempering for tool steel, nitriding for 38CrMoAl) with hardness testing.
4. Surface treatment (idan ya dace) with adhesion testing.
5. CMM dimensional inspection (full tolerance verification).
6. Dynamic balance testing (ISO 1940-1:2016) – vibration amplitude <0.1mm at max operating speed.
7. Final visual inspection and certification (abin ganowa, dimensional report, hardness report).

All quality control data is retained for 10 shekaru, ensuring full traceability for regulatory compliance (IATF 16949 don mota, FDA for medical).

• Quarterly Maintenance:
  • Remove the screw for full inspection (measure flight thickness, check for corrosion/cracking).
  • Polish minor wear on flight tips (using 400-grit sandpaper) to restore dimensional accuracy.
  • Inspect barrel liner for wear (replace if necessary to maintain optimal clearance).

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).
• Tsare-tsare >0.8mm (dawo da kayan abu yana rage haɓakar extruder ta >20%).

Q: How do I select the right material for my extrusion application?

A: Excellence’s technical team provides a free material selection guide based on:

• Nau'in kayan abu (budurwa/sake yin fa'ida, filled/unfilled, corrosive/non-corrosive).
• Extrusion temperature (high-temperature engineering plastics vs. standard polymers).
• Production volume (24/7 operation vs. batch production).
• Kasafin kudi (upfront cost vs. jimlar kudin mallaka).

We also offer a trial program (30-day test of a sample screw) for new customers to validate performance before full purchase.

Q: What warranty is provided for Excellence screw components?
