product features
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.
Featured Roughcast
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.
Gun Driller
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.
Countersinking process/Pre-drilled
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
