Do you know the “shaping master” of biomass pellets – molds?
Full analysis of biomass pellet machine molds: types, materials and customized services
The mold of the biomass pellet machine is the “shaping master” and “industrial heart” in the biomass fuel molding process. Its design and material directly determine the density, output and equipment life of the pellets. The following is a systematic analysis from three aspects: mold type, core material and customized service to help you choose efficiently.| Comparison Dimensions | Ring die mold | Flat mold |
| Applicable raw materials | Sawdust, hardwood and other coarse fibers with low bonding rate | Loose fibers such as straw, rice husk, organic fertilizer, etc. |
| Structural features | Ring die, vertical or horizontal installation, high pressure extrusion | Flat mold, vertical feeding, adjustable pressure |
| Pressure and capacity | High pressure, suitable for large-scale production | Adjustable pressure, suitable for small and medium production capacity |
Typical application scenarios
Ring die: industrial-grade biomass fuel pellets (such as wood chip pellets), which require high-density molding; Flat die: organic fertilizer, straw pellets and other fields that require low molding pressure;Biomass pellet machine mold material: alloy steel vs stainless steel
Mold material directly affects wear resistance, life and pellet quality. The comparison of mainstream material characteristics is as follows:| Material Type | Features and Benefits | Applicable Scenarios |
| Alloy Steel | High hardness and strong wear resistance | Highly abrasive raw materials such as sawdust and hardwood |
| Stainless Steel | Corrosion resistant, smooth particle surface | Aquafeed, high moisture raw materials or export pellets |
Key points for material selection:
Alloy steel: After quenching treatment, the hardness reaches HRC55-60, suitable for continuous high-pressure production; Stainless steel: avoid raw materials from corroding the mold and ensure the cleanliness of the particles, but the cost is relatively high.Customized mold service: full model coverage and brand adaptation
We provide multi-model and multi-brand mold customization and supply services to meet diversified production needs:
Full model coverage
Ring mold: adapt to mainstream models such as 850, 700, 560, 460.
Flat mold: support customization of various small and medium-sized equipment (such as organic fertilizer granulator).

Conclusion
The reasonable selection of biomass pellet machine molds is the core of balancing production efficiency and cost. Ring molds and flat molds are suitable for different raw materials and scales, alloy steel and stainless steel materials can cope with differentiated wear environments, and flexible full-model customization services can accurately match the equipment needs of brands such as Yuguan and Yulong. Scientifically selecting molds can achieve the sustainable production goal of “low energy consumption and high output”.
