American user Mr. P.A.’s ring die usage record of Hongyang Machinery

In December 2024, Mr. P.A., an American feed industry practitioner, came to China. Under the recommendation of European customers, he selected Hongyang Feed Machinery Co., Ltd. among many factories and ordered a CPM country100 ring die for trial production for his customers.

After five weeks of running the ring die, Mr. P.A. compared it with the American equipment used in the same shop. During the return visit, he provided the following information: “When the ring die purchased by a local company in the United States was used for 2 weeks, the bell mouth suffered destructive wear and could no longer be used. However, after Hongyang’s ring die was used for another five weeks, the feed port remained intact and production could continue.” In March 2026, Mr. P.A. came to the Hongyang factory again and told us that his customer liked this ring die very much and wanted to order 20pcs ring die of the same specification at one time. He also emphasized that no changes should be made as long as this ring die is from this hongyang company.

Why does Hongyang’s ring die perform better?

Hongyang Machinery has provided granulation equipment and molds to users in different regions and industries over the past many years. The types of materials involved include:

The granulation requirements of the above-mentioned different materials are significantly different. Hongyang has accumulated corresponding hole parameter data and process experience in long-term practice. For a specific material, Hongyang can select or adjust parameters such as aperture, effective length, taper, etc. based on its physical characteristics instead of applying general specifications. The ring mold and hole pattern scheme used by Mr. P.A. are matched based on the characteristics of the feed formula actually produced.

The ring mold is the core component of the granulation equipment. The hole structure directly affects the discharging efficiency, particle molding quality and mold life. Different materials have significant differences in fluidity, friction coefficient, moisture content sensitivity and granulation characteristics during the granulation process. They have different requirements for the hole shape, aperture, effective length, inlet taper, inner wall smoothness and other parameters of the ring die.

Hongyang selects specific grades of materials on the material side and has clear process requirements for the forging ratio and tempering hardness of the ring die blanks. After the die hole is processed, the inner wall smoothness is controlled within the specified range to reduce the material extrusion resistance. The cooperation of these links allows the core components to wear evenly during high-load continuous operation, and the overall replacement cycle can be extended.
