what we can offer you

Poultry and livestock feed ring die 

Biomass wood pellets ring die mold 

Shrimp feed Ring Die 

Our Poultry and Livestock Feed Ring Dies are engineered for high-volume production in 10-50TPH feed mills. Specifically designed for processing corn and soybean-based formulas, these dies feature a precision-calculated compression ratio to ensure high PDI ( 98%) and low energy consumption. Trusted by global giants like NEW HOPE GROUP and Gold Coin, our X46Cr13 stainless steel dies are 100% compatible with CPM, Buhler, and SZLH series machines, ensuring stable output for poultry, cattle, and pig feed production

Built to withstand extreme pressure, our Biomass Wood Pellet Ring Dies are the preferred choice for challenging hardwood and softwood pelleting. Featuring reinforced structures and vacuum-quenched X46Cr13 steel, these dies are optimized for high-density biomass fuel production. With a proven track record in the South African market—including specialized 6mm solutions for HVE Woodpelleting—our dies offer superior wear resistance and a mirror-polished interior to prevent clogging in high-fiber environments."

Precision is the core of our Shrimp Feed and Aquafeed Ring Dies. Designed for 1.5mm to 2.0mm micro-pellets, we utilize 8-axis CNC high-speed drilling to ensure perfectly smooth hole walls and uniform pellet length. These dies are essential for high-end aquatic feed producers like NUTRITEC, where water stability and precise nutrient delivery are critical. Our specialized vacuum heat treatment ensures that even with thousands of micro-holes, the die maintains maximum structural integrity and corrosion resistance."

Why Choose Us

Why Choose Wuxi Gamma? | Your Tier-1 Partner for High-Performance Ring Dies

1. Premium Forged Blanks for Extended Service Life 

We use only high-density forged alloy steel and stainless steel (X46Cr13) blanks. Unlike common cast materials, our forging process eliminates internal defects and enhances structural integrity. This results in superior wear resistance and a proven service life of 800-1,200 hours, even in the most demanding 24/7 production environments of giants like New Hope and WATANIA.

2. 8-Station Deep-Hole Gun Drilling 

Precision is at our core. We utilize advanced 8-station CNC high-speed gun drilling centers to process every die hole. This technology ensures:

Perfectly Smooth Interior Walls: Reduces friction and prevents clogging.
Zero-Hour Break-in Period: Mirror-polished holes allow you to reach full capacity immediately.
Uniform Compression: Guaranteed consistent pellet quality from the first bag to the last.
3. Rigorous Quality Control & Inspection 

Quality is never an accident. Each Wuxi Gamma ring die undergoes a multi-stage inspection protocol:

Ultrasonic Flaw Detection: To ensure zero internal cracks in the forging.
Vacuum Heat Treatment Monitoring: Precise HRC 52-55 hardness testing for uniform strength.
Dynamic Balance Testing ($\leq 15g$): Minimizes machine vibration, protecting your pellet mill's main shaft and bearings.
4. Expert Customization & Parameter Support 

With decades of experience serving diverse markets from South Africa (Biomass) to South America (Aquafeed), we offer more than just a part. Our engineers provide:

Formula-Based Customization: We optimize the Compression Ratio based on your specific raw materials (Fiber, Fat, and Protein content).
Global Case Experience: Whether it's 6mm wood dies for HVE Woodpelleting or 1.5mm shrimp dies for NUTRITEC, we provide the exact technical parameters to maximize your PDI and ROI.

FAQ

Please enter the title here

Q1: How do you ensure the ring die's service life in 24/7 high-capacity production?

A: We use high-density premium forged blanks (X46Cr13) and vacuum heat treatment to reach a uniform hardness of HRC 52-55. Unlike standard cast dies, our forged dies eliminate internal stress and micro-cracks. This allows our components to consistently reach 800-1,200 hours of operation in 10-50TPH lines, as proven in the facilities of Gold Coin and New Hope Group.

Q2: Does your ring die require a long break-in period before reaching full capacity?

A: No. Thanks to our 8-station CNC gun drilling and specialized mirror polishing technology, the interior walls of the holes are extremely smooth (0.8). This ensures a 0-hour break-in period. You can achieve maximum output and a 98% PDI from the very first batch, significantly reducing downtime and energy waste.

Q3: Can you customize the compression ratio for specific feed formulas or biomass?

A: Absolutely. A "one-size-fits-all" approach leads to poor pellet quality. Our engineering team provides free parameter support. We calculate the optimal Compression Ratio based on your specific raw material (e.g., high-fiber poultry feed in Saudi Arabia or challenging wood biomass in South Africa). We have a database of thousands of formulas to ensure your pellets meet international standards.

Q4: Are your spare parts 100% compatible with international brands like CPM or Buhler?

A: Yes. We specialize in high-precision replacement parts that are 100% interchangeable with OEM components. Whether it is a ring die for a Buhler DPAB, a roller assembly for a CPM 7900, or extruder screws for aquatic feed lines, our parts are CNC-machined to original tolerances, providing a cost-effective yet high-performance alternative for global plants like NUTRITEC.

Q5: What measures do you take to prevent rust and damage during sea freight?

A: We understand the importance of part integrity upon arrival. All spare parts, including extruder screws and conveyor scrapers, undergo an anti-rust oil coating and are wrapped in protective plastic film. We use fumigation-free, reinforced export wooden cases to ensure that your order arrives in perfect condition, whether you are in Egypt, Brazil, or the UAE.
