Features of pellet ring die

1. Made 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.

3. Ring die can be produced up to 300mm-1500mm in diameter and 500mm 
     in height.

4. In ring die processing, full automatic control, one-time molding for die hole, 
    high smoothness.

Different Materials of Pellet 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.
 

Relations between die hole structure and pelleting

1. Straight hole and release stepped hole

     It is suitable for compound feed processing

2. External conical hole

     It is suitable for the processing of high-fibre feed like de-fat chaff

3. Internal conical hole and compression-type stepped hole

    This applicable for the process of herbage powder feed of light proportion

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

Good quality gun drill equipment, tools and drilling hole software:

1. Die hole position high accuracy, up to 15 seconds per circle. High accuracy of 
    position ensures both high dimensional accuracy and uniformity of materials and 
    uniformity in die wearing and forces of radial direction and peripheral direction.

2. High rotating speed and imported tools and cooling liquid ensures process 
    conditions as drilling required.Thanks to such conditions, the processed die hole
    features small roughness, Ra 0.8 and smoothness, which can ensure pelleting 
    output, quality and debugging convenience.

3. The application of drilling hole software is favorable to increase porosity of ring 
    die and optimize its way of aperture and therefore pelleting output, quality and 
    service life of die is guaranteed.

3. Vacumm Hardening-America Vacuum Furnace

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.
