Knowledge Sharing for Your Success

Symptoms: Powder doesn't flow through Hall funnel or clumps in die.
Likely Causes: Moisture absorption, agglomeration, contamination.
Solutions: Dry powder at 80–100°C for 1–2 hours. Re-screen if severe agglomeration. Check storage conditions for moisture ingress. Verify packaging seal integrity.

Symptoms: Parts crack during ejection or handling before sintering.
Likely Causes: Oxidized powder surface, excessive lubricant, incorrect mixing.
Solutions: Use fresh powder. Reduce lubricant content (<1.5%). Increase mixing time. Check compaction pressure. Verify powder grade matches application.

Symptoms: Final parts have higher porosity than expected.
Likely Causes: Oxidation during sintering, poor atmosphere control, insufficient sintering.
Solutions: Verify atmosphere dewpoint (-20 to -40°C). Increase sintering time or temperature. Check oxygen content in powder. Ensure protective atmosphere from room temperature. Check for furnace leaks.

Symptoms: Inconsistent braking performance, variation within batch.
Likely Causes: Poor copper distribution in friction material mix.
Solutions: Increase mixing time (15–20 min minimum). Verify apparent density of copper powder batch. Check for segregation during processing. Ensure proper mixing equipment.

Symptoms: Diamonds fall out of matrix before wearing away.
Likely Causes: Matrix too soft, insufficient copper content, poor sintering.
Solutions: Increase copper percentage in matrix. Add strengthening elements (iron, cobalt). Optimize hot pressing conditions (temp, pressure, time). Verify diamond surface treatment.

Symptoms: Parts grow or shrink more than expected.
Likely Causes: Powder characteristics, improper formulation, sintering conditions.
Solutions: Review powder grade selection. Adjust formulation (graphite content, alloy additions). Optimize sintering temperature and time. Consider pre-mixed powder with controlled dimensional change.
