Feature of our ring die:
1Made of imported high-carbon high-chromium stainless billet steel,optimization carbon,thus enhancing wearing and corrosion resistance and hardness.
2 It can deal with all kinds of die hole over &1.2mm (&1.2mm included) and compression ratio.
3Ring die can be produced up to 300mm-1500mm in diameter  and 500mm in height.
4In ring die processing, full automatic control, one-time molding for die hole, high smoothness.
 strong tensile strength,good wear resistance, good corrosion resistance,high wear resistance,long life.
 
Advantage of our ring die:
1.Material refining technology,fewer impurities,high purity,largely reducing harmful elements content(such as 
elements S,P ), thus comprehensive mechanical performance of material is raised.
2.Through roll forging, material is processed and strengthened and material fibre is complete and uniform, 
which increases integrated mechanical performance of material.
3.FDSP Company has the world advanced forging equipment and technology,electronic data processing 
systems and perfect quality control system.
4.Ring die blank,generally chromiumalloy roll forgings, some factories use 45 ordinary carbon steel.
5.Hardness of blank must be controlled, ranging from HB170 to HB220.If the hardness is too high,the drill is 
easy to break and happens with die hole when drilling. If hardness is too low, the surface finish of die hole 
will be not good.
6.In order to control blank inner material uniformity, every blank must be carried out with fault detection, 
which can avoid defects such as flaw, pore-free,crackle and inclusions etc.
7.After machining and heat treatment process, hardness of ring die can be up to HRC 52-58(inner diameter less than 350mm),HRC50-56(inner diameter more than 350mm),more wearable and 
anti-corrosion.
8.In order to control hardness uniformity of ring die after heat treatment, we choose more than three points 
in each part of trisection of peripheral direction to test hardness and take average.The difference of 
hardness value between each part should not be higher than HRC4.
9.According to the principle of metal material science combined with gas quenching and C,Cr,Mn,Ni,V elements content is optimized, forming the standard of ring die.
 
Relation between die hole structure and pelleting:
Straight hole and release stepped hole is suitable for compound feed processing
External conical hole suitable for the processing of high-fibre feed like de-fat chaff
Internal conical hole and compression-type stepped hole applicable for the process of herbage powder feed of light proportion
We should try to avoid using release stepped hole(pressure-relief vent)
Because discharing is not easy for holes in the rows of the edge of ring die, pressure-relief vent is designed there.
 
Production process:
1.Precision Machining:
CNC machining center
CNC machining center assure high dimensional accuracy,geometric tolerance and surface roughness.

2.Hole Machining
Germany gun drill
 
The quality and service life of die is guaranteed.
 
3.Vacuum Hardening
 
America vacuum furnace:
1.High vacuum degree, no oxidation reaction in ring die surface, ensuring original smoothness of die hole 
inner surface.
2.High vacuum degree,twisting bottom and convection heating minimize ring die deformation.
3.CNC controls process program, ensuring ring die quality stability.
4.With rationally adjusting heat treatment, heat preservation and cooling rate and time, microstructure of 
ring die can achieve its most suitable working conditions.
5.High cooling speed ensures more even distribution of carbide and hardenability and uniformity of ring die is guaranteed, contributing to balance using of ring die.
