TOPS
Warm Powder Feed System
(Thermally Optimized Powder System)
Warm compaction and die wall lubrication techniques each can improve
part density by up to 0.2 g/cm3 as compared to conventional die
compaction. Combining these two methods achieves greater density

The
TOPS System is available in 5 zone or 7 zone heating configurations:

Benefits
• Increased density and green strength.
• Lower compaction tonnages.
• Lower ejection tonnages.
• Increased length/diameter ratios with less density gradients
• Possible elimination of the need for a double-press, double-sinter
process.
• Reduce/elimination of internal lubricants.
• Increased density allows for green machining.
• Reduced parts scrap due to increased green strengths.
