Why Choose Hongyue Spare Parts?
Precision manufacturing for ultimate pelleting performance.

Deep Carburization
Advanced carburizing heat treatment achieves HRC 58-62 surface hardness while maintaining a tough inner core, providing extreme wear resistance against abrasive wood fibers.

CNC Gun Drilling
Precision gun-drilled holes with controlled geometry ensure consistent pellet density and maximum throughput for hardwood and softwood biomass pelleting.

Reinforced Blank Forging
High-pressure forged blanks eliminate internal metallurgical defects, preventing catastrophic die failure during high-pressure biomass compression.
Premium Material & Extended Lifespan
Forged from high-grade X46Cr13 (Stainless Steel), our replacement ring dies and roller shells offer superior resistance against corrosion and abrasive wear during high-temperature pelleting. Processed through advanced vacuum heat treatment, we ensure a uniform hardness (typically HRC 52-56), which maximizes output capacity while minimizing the cost per ton of feed produced.
Frequently Asked Questions
Can this stainless steel die handle wood pellet production? ▼
Yes, X46Cr13 stainless steel is specifically chosen for biomass applications due to its superior corrosion resistance against wood resin and acetic acid.
Is this die compatible with CPM 7722-7? ▼
Absolutely. Our dies are reverse-engineered to match both CPM 7722-6 and 7722-7 specifications with precision clamp mounting.
Why Material Matters
The lifespan of a ring die is determined by its material composition and heat treatment. We use only certified X46Cr13 stainless steel and 20CrMnTi alloy steel, processed through vacuum heat treatment to ensure uniform hardness and maximum wear resistance.
