When producing ring dies, it’s crucial to select the appropriate compression ratio based on the type of feed material. For poultry feed, the compression ratio typically ranges from 1:11 to 1:16, while for cattle and sheep feed, it’s between 1:7 to 1:10. Fish and shrimp feed require a higher compression ratio of 1:20 or above, and biomass wood pellets fall within the range of 1:4 to 1:7. Additionally, the depth of the release holes in the first three rows and the middle rows must be considered, along with calculating the open area rate and confirming the hole number layout. These steps are vital in creating the final production drawings for our ring dies, ensuring precision and efficiency in our manufacturing process.
We verify the precise ratio of Chrome, Carbon, and Nickel in our X46Cr13 stainless steel. This ensures your ring dies meet international anti-corrosion and toughness standards from the source.
A 100% visual and technical inspection of forged blanks. We eliminate any cracks, inclusions, or folding to ensure a flawless substrate for CNC deep-hole drilling.
Using industrial ultrasound to detect internal porosities or micro-cracks. This guarantees structural integrity and prevents breakage during high-load 10-20TPH production.
Strict Rockwell (HRC) testing before and after vacuum hardening. We maintain a consistent hardness of HRC 52-55 to balance maximum wear resistance with impact toughness.
Microscopic analysis of the steel’s grain structure. We ensure uniform carbide distribution, which is the secret to maintaining a mirror-smooth hole surface over a long service life
A high-performance ring die is more than just a steel mold; it is a masterpiece of precision engineering. At Gamma Tech, we transform raw high-chrome stainless steel into industrial-grade components through a rigorous multi-stage manufacturing process. By integrating advanced CNC deep-hole drilling with state-of-the-art vacuum heat treatment, we ensure every hole is mirror-smooth and every surface is hardened to perfection
