Why Choose Tianyou Spare Parts?

Precision manufacturing for ultimate pelleting performance.

1

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.

2

Vacuum Heat Treatment

Computer-controlled vacuum quenching achieves uniform HRC 52-56 hardness throughout the die body, preventing premature cracking under heavy pelleting loads.

3

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

Why choose X46Cr13 for shrimp feed ring dies?

Shrimp feed requires small holes and high compression. X46Cr13 stainless steel offers superior toughness and resists the corrosive nature of steam and aquaculture feed ingredients.

Can this die prevent hole blocking during 1.8mm feed production?

Yes, we apply a multi-step mirror polishing process to the 1.8mm holes, drastically reducing friction and preventing material from burning and blocking the die.

The Heart of Pelleting

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.
