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
What is the difference between MUZL420TW and MUZL420M? ▼
The TW features a twin-hole pattern optimized for floating aquaculture feeds, while the M is a standard single-hole pattern. Both mount identically on the same Famsun machine.
Is this die suitable for shrimp feed production? ▼
Yes, our 2mm and 3mm hole sizes are specifically designed for shrimp feed and fine-particle aquaculture feed production.
Precision. Hardness. Lifespan.
The Ring Die is the core of any pellet mill. A poor quality die means blocked holes, high energy consumption, and frequent downtime. Tianyou Machinery delivers OEM-quality replacement parts that match the exact specifications of major European and Chinese brands, but at a 30-50% lower cost.
