China Sinking Fish or Poultry Feed Pellet Mill Ring Die for Szlh Series

1:about the ring die:
Ring die is the core part of pellet mills which plays very pivotal role in pelleting process,so it is most important to choose the appropriate ring die and brand manufacturer for pellet mills. Not only does ring die will improve the yeild and quality of feed. but also it can reduece cost of production and maintanence.
As one old and famous ring die and spare parts manufacturer with 30 years old in China, Shanbao machinery is not only one TOP manufacturer for such parts, most importanct is that we always supply all kinds of solutions&schemes according to customer's requirments, such as different compression ratio, different formula for feed , different opening rate, different hole arrangments ..........
These specialities above make us big difference from those small and unnamble pellet die producers, they just copy your die'dimention and make it, but never design it.
2: How to manufacture one high quality ring die?
Just as one Chinese proverb says: good tools are prerequisite to the successful execution of a job, the same truth also applies to the ring die's manufacturing. only the best equipment and technology can maufacture the high quality die and other spare parts.
A:Die metallurgy-Carbon and Chromium
The basic physical properties of the die materials are controlled by the heat treating process and the composition of the die's steel.
The two key elements in our dies are carbon and chromium. The carbon content of the steel affects the corrosion resistance and the wear resistance of the die. A free chromium content above 12% classifies a steel as stainless. Chromium carbides are formed during the heat treat process through a combination of chromium and carbon atoms, which increases wear resistance.
B: Forging and Casting
As one TOP dies and spare parts manufacturer in China, we are the onLY one who has our own forging and casting plant named sichuan huabao machinery comany, almost all blanks of ring dies are made by ourself, instead of purchasing from other company, this is important for delivery time and ring die's quality, becasue we can cotrol the quality and delivery time of blanks of ring dies.

C: Hole-Drill by Guning-Drilling Machine
Usually, if one company wants to manufacture ring dies, they must firstly purchase the core equipment(Gun-Drilling Machine) from other machinery manufacturing companies,but our company needs not, We are the onLY ONE ring dies manufacturer in China who needs not buy such machines from outsides , because we have the strong ability to design and manufacture it independently by us, no one can compete it with us in China, even whole world !
D: Counterbore, bolt hole and key way processing
Automatical chamfering machine is very high-efficiency in counterbore processing, not only does it save time, but also improves accuracy, now almost all good and top manufacturers are using such machine to repalce the traditional twist hole-drilling machine, and we also have the ability to manufacture such machine.
E: Heat Treating: carburizing vs. neutral hardening
We heat treat our dies by two different ways, either carburizing the die or neutral hardening the die. Case carburizing dies can be done in a pit furnace or in a vacuum furnace by the addition of a carbon rich gas, such as propane. The Alloy Die is processed in the pit furnace. When carbon is added into the atmosphere of either of these furnaces, it soaks into the steel to form a hard case. Case carburized dies tend to create more friction in the pelleting chamber, meaning they will usually provide better quality pellets. Neutral hardening is a process that gives the same relative hardness throughout the thickness of the die. Due to its homogeneous hardness throughout, Chrome Plus offers excellent die life. Neutral hardened dies tend to be easier to start.
F:final machining and quality-checking:
One perfect ring dies needs more complex manufacturing steps to ensure its good quality, As one ISO9001-2015 company, we also pay more attetion to each step, final maching and quality checking are necessary before delivery.

Our compamy can manufacture ring dies for mainstream brands of pellet mills including ANDRITZ, IDAH, CPM,BUEHLER,ZCME, IEMME, JKAP, SOGEM, MATADOR(UMT), MABRIK,PTN, PALADIN, PTN, PROMILL,YEMMAK, FAMSUN...
