Why Choose Tianyou Spare Parts?
Precision manufacturing for ultimate pelleting performance.
CNC Gun Drilling
Imported 4-axis gun drilling center ensures ultra-smooth inner hole finish (Ra 0.8), reducing blockage and improving pellet quality for consistent feed output.
Vacuum Heat Treatment
Computer-controlled vacuum quenching achieves uniform HRC 52-56 hardness throughout the die body, preventing premature cracking under heavy pelleting loads.
Precision Counter-Sink
Multi-step counter-sinking and chamfering process creates a smooth entry cone for each hole, ensuring consistent feed flow and reduced energy consumption.
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
Is this Yemmak 520.138 die compatible with the 420.138? ▼
No, the 420.138 and 520.138 have different mounting specifications. Please select the correct model for your pellet mill.
What compression ratio do you recommend for broiler feed? ▼
For broiler feed, we typically recommend a compression ratio of 1:9 to 1:11, which provides optimal pellet durability and digestibility.
为什么材质至关重要
