In the field of high-end concrete brick production, particularly when operating machinery like the DF7-10S Hyper Press which exerts a massive 500-ton hydraulic pressure, the choice of pallet material is a critical factor for both production efficiency and product quality. Standard pallets often fail under the extreme mechanical stress of static pressure molding, leading to cracking, deformation, and uneven brick height.
1. GMT Pallets: The High-End Strength Standard
GMT (Glass Mat reinforced Thermoplastics) pallets are the preferred choice for 500-ton hydraulic brick machines. Composed of high-strength glass fiber and thermoplastic resin, GMT pallets offer an exceptional strength-to-weight ratio. They can withstand repeated high-pressure cycles without permanent deformation. For the DF7-10S series, GMT pallets ensure that the interlocking bricks are molded with 100% precision, preventing the "pressure leakage" common with inferior materials.
2. PVC Pallets: The Durable Workhorse
PVC pallets provide a balanced solution for medium-to-high pressure production lines. Known for their chemical resistance and high density, PVC pallets are ideal for environments where moisture and alkaline concrete additives are prevalent. They offer a smooth surface that facilitates easy brick release, ensuring the sharp edges required for high-quality paving stones.
3. Comparative Performance in 500-Ton Environments
While PVC is cost-effective, GMT is superior in vibration absorption and impact resistance. When the hydraulic system of a machine like the DF7-10S engages, the pallet must support the entire vertical load. GMT’s multi-layered fiber structure distributes this force evenly, significantly extending the pallet's lifespan to over 8-10 years.
Conclusion: For independent site operators focusing on quality and longevity, investing in GMT or high-density PVC pallets is not just an expense—it is a strategic asset. Darifeng Machinery recommends GMT pallets for our heavy-duty hydraulic series to maximize the potential of our pressure-molding technology.
