Materials of Ring Die
1. Alloy dies
This is the choice for many feed processors because of their good abrasion and breakage resistance.
2.  Carbon steel die
They have superior corrosion resistance, making them the choice for processing operations involving corrosive chemicals.
3. Stainless steel dies
They have the best abrasion and  breakage resistance as well as good corrosion resistance.




Process Of Ring Die
1,Precision Machining
CNC machining center :assure high dimensional accuracy,geometric tolerance and surface roughness.
2,Hole Machining
Our company's die is made by international advanced German gun drill, tools and drilling hole software.Which ensures process conditions as drilling required, therefore high pelleting output, quality and debugging convenience
3,Vacuum Hardening
American vacuum furnace:High vacuum degree, no oxidation reaction in ring die surface, ensuring original smoothness of die hole inner surface ,has long service life and high quality.High cooling speed ensures more even distribution of carbide hardenability and uniformity of ring die.
