Dies-steel mould

FDSP dies are manufactured in the following steels:

X46Cr13 (i.e."stainless" steel or "chrome-steel") 

20MnCr5 (i.e."alloy" steel)

18NiCrMo5 (i.e. similar to 20MnCr·5 but with a higher alloy content).

The X46Cr13 steel dies are vacuum / through hardened. The heat treatment achieves 53-55HRc hardness on the surface and in the core. The high chrome content makes it corrosion resistant. Although it costs more than a normal alloy, X46Cr13 is by far the most common material used through out the feed milling industry.

Pellet ring dies

Pellet Diesmade in 20MnCr5 and18 NiCrMo5 steel, on the other hand, are case hardened to obtain 60-62HRc hardness for approximately 0.8-1.2mm. Under the case hardened layer the steel remains malleable and therefore less brinle. The pellet mill dies made of this steel are more resistant for pelleting extremely difficult fibre-rich products such as beet pulp, alfalfa, straw and hay.

Dies-perfect drilling

FDSP ring dies have an extremely precise and regular perforation: the "honey comb" layout of the holes is faultless.

Deep hole via gun drill drilling: ring die holes array evenly, uniform wall thickness between holes, to ensure ring die works successfully in pellet mill with smooth surface of pellet. It is important to upgrade smooth and polish level of ring die holes in order to decrease temperature difference, lower energy consumption, raise capacity, and reduce loss of nutrition FDSP reach international advanced level relate to hardness of ring die, evenness and smoothness of holes.

Vacuum heat treatment

1. Suitable hardening temperature of vacuum furnace ensures higher hardness and impact toughness.

2. Suitable drawing temperature ensures no cracks of ring dies and little wear of hole and surface, which improves the workinglife.

3. In same loading, adding backfill air pressure will boost die's cooling and hardness.

4. CNC control technology ensures the stability of ring dies.

Relations 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.
