With the increasingly fierce competition and high demands in the shrimp feed market, based on 1.0mm aperture, ZHENG CHANG firstly produced small-aperture shrimp feed ring die with 0.8mm aperture, and did the pilot production in Yuejia production base, Guangdong Yuehai Group. Pellet mills with the ring die produce feed pellets smoothly. The pellets with neat appearance, uniform diameter and color, and good stability, can fully meet customers’ quality requirements.

The shrimp feed ring die uses vacuum stainless steel as its raw material with special alloy elements. The furnace imported from the US and the continuous quenching furnace imported from Japan, with uniform hardness, good wear resistance, and a combination of heat-treatment process, ensure that the ring die is more wear-resistant and has longer service life.

Four-axis gun drill imported from Germany makes die holes array evenly and glossy, assuring smooth pelleting process and uniform pellets.
