Global pellet production continues to increase, both for fuel pellets such as wood pellets and feed pellets such as poultry and ruminant feed pellets. Global wood pellet production in 2025 is estimated to reach 50-54 million tons. Global wood pellet production is projected to surge dramatically by 2050, reaching 170 million to 250 million tons per year, or around 3-5 times the current level. This surge is driven by the Net Zero Emissions scenario proposed by various global energy agencies. Meanwhile, global feed pellets production in 2025 is estimated to reach around 1.41 to 1.42 billion metric tons, or more than 25 times the production of wood pellets in the same year. Global feed pellets production in 2050 is projected to reach 1.8 billion to 2 billion tons. This increase is driven by human population growth, which is predicted to reach 9.7 billion people, which automatically increases the demand for animal protein. Both the production of fuel pellets such as wood pellets and feed pellets uses the main tools, namely pelletizers and ring dies, which are important components that require periodic replacement.
Just as car tires wear out after a certain distance, so too do pelletizer ring dies. After thousands of tons of pellets are produced, the ring die will wear out and must be replaced. Just as car tires affect the speed of wear, so too do pelletizer ring dies, where the condition of the raw materials affects the wear rate. To ensure optimal tire and ring die service life, they must be designed for their intended purpose. For example, a highway terrain (HT) tire, designed specifically for smooth asphalt, will be less than optimal for use on dirt or light gravel like rural roads, more over muddy terrain. Similarly, a ring die designed for feed pellet will be less than optimal when used with agricultural waste, more over woody biomass.

Car tire treads have distinctive characteristics depending on the terrain they are used in. For example, off-road tires with large, checkered treads are very durable in mud, but very noisy and unstable on asphalt. Similarly, the design of pelletizer dies. The characteristics of the raw material significantly influence the shape of the holes. Hardwood can differ from softwood, and even more so from agricultural waste, more over feed pellets. The shape of the holes in the pelletizer die significantly determines the density and quality of the final product. For example, a straight hole profile is the most standard shape. It is used for materials that are easy to compact and do not require extreme pressure. A relieved bore profile, on the other hand, has a larger outer diameter than the inner one (where the compression is applied). This reduces friction, preventing the machine from overheating and is commonly used for wood pellets. A tapered hole, on the other hand, tapers outward. It provides very high compression pressure, making it suitable for materials that are difficult to adhere or have coarse fibers.
Unlike tire manufacturers, which are typically separate or distinct from their car manufacturers—for example, Mercedes-Benz doesn't produce its own tires—almost all pelletizer manufacturers also produce their ring die pelletizers. While some companies specialize in die production, there are few. As global pellet production, both for fuel pellets like wood pellets and feed pellets, increases, the need for ring dies increases. Relying solely on ring dies from the original pelletizer manufacturer can be time-consuming, while pellet manufacturers need them as quickly as possible.
This creates a niche market for pelletizer dies and spare parts. Pelletizer manufacturers, in addition to producing ring dies for their pelletizers, can also customize or produce them to order. For example, the German pelletizer manufacturer Muench, in addition to producing ring dies for its machines, also produces ring dies for CPM, Andritz, Salmatec, and other machines. The quality of the steel material used for the ring die and the workmanship determine the quality of the ring die.
