Why Choose Tianyou 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 20CrMnTi (Alloy 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
Why use Alloy Steel (20CrMnTi) instead of Stainless Steel for wood pellets? ▼
Wood pelleting is highly abrasive but not corrosive. 20CrMnTi alloy steel allows for carburization, reaching HRC 58-62, which offers far superior wear resistance against wood fiber compared to stainless steel.
What is the lifespan of this CPM 7932 wood die? ▼
Depending on the wood species (hardwood vs softwood) and sand content, our premium alloy dies typically run for 1,500 to 2,000+ hours.
为什么材质至关重要
环模的使用寿命取决于其材料成分和热处理工艺。我们仅使用经过认证的X46Cr13不锈钢和20CrMnTi合金钢,通过真空热处理确保硬度均匀和最大耐磨性。
