The quality and life of the ring die can best determine the quality and efficiency of pellet feed production. How to create a high-quality ring die, save costs and increase revenue for customer s, the quality of its raw materials and processing technology are ver y important. In last 20 year s, Gamma Tech has made the fir st ring die . After several technical and ser vice innovations, it has become the fir st choice for many large groups to choose good mold manufacturer s.
The ring die roughcast is made of vacuum stainless steel material containing special alloy elements, and ultrasonic flaw detection is used to strictly control the quality of the ring die source. From the time the roughcast is put into storage, it needs to be left standing outdoor s for 30 days to allow it to fully contact and oxidize with the air before it can enter the main process flow.
Forging roughcast pretreatment
The solid solution spheroidization pretreatment process is adopted to refine the internal structure and grain of the roughcast, further improve the strength of the forging, and greatly reduce the deformation amount of the final quenching heat treatment.
Semi- finishing/ Stencil line/Mill keyway
The ring die can be turned from a roughcast shape to the specified size, which can be customized according to the different needs of customer s, such as: adding a certain amount of thickness to the hoop surface to achieve a closer fit between the ring die, the hoop and the hollow shaft. Input the parameter s of the ring die into the computer, and the automatic stamping machine ensures the accuracy. According to the different parameter s of the ring die, it is completed by an automatic integrated keyway milling machine, which ensures the accuracy of the keyway and screw hole positions without deviation.
A good gun drill is the key to the production of high-quality ring die. Gamma Tech has a series of professional gun drill equipment including: German imported four- axis gun drill, South Korean four- axis gun drill and American gun drill. The rate reaches 65600 holes, which basically covers most of the ring die size requirements in the market.
Different counterbore processes can now be introduced according to different feed types and different apertures, such as: conical counterbore for livestock and poultr y feed, etc. Specialized standard, the angle deviation of drilling is controlled within 1° , or even smaller

Finish machining/Water blasting
Reach the specified size, ensure that the size is within the tolerance range, and the inspector will pass the inspection before entering the next process. For the small aperture ring die, the sandblasting process improves the smoothness of the inner wall of the die hole and makes the discharge smoother
