Why Choose Hongyue 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
Does this ring die fit the Kahl 24-390? ▼
Yes, it is designed with exact flange tapers to fit the clamp mounting system of the Kahl 24-390 pellet mill.
Can I use this for pig feed? ▼
Yes, 3mm or 4mm holes with a standard compression ratio work excellently for pig feed formulations.
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.
