Factors Influencing Pallet Load Capacity
Compression Force:
Pallets manufactured using a 1000-ton press are suitable for light-to-medium loads.
Pallets manufactured using a 1300-ton press have higher density and are ideal for medium-to-heavy loads.
Raw Material Composition:
High-density wood particles increase pallet strength and load-bearing capacity.
Addition of binding agents (e.g., resins) enhances durability.
Design Features:
Reinforced Mold Design: Adds structural strength for handling heavier loads.
Vent Holes: For ventilation and weight reduction without compromising strength.
Type of Load:
Static Load: Weight the pallet can bear while stationary.
Dynamic Load: Weight the pallet can bear while being moved (e.g., on forklifts).
Moisture Resistance:
Proper resin usage and curing ensure pallets are resistant to environmental factors like moisture, extending lifespan.
Customization Options
Nestable Pallets: Save space during transportation and storage.
Four-Way Entry Design: Allows forklift access from all sides.
Ventilation Holes: Reduce weight while maintaining strength.
Fire Retardant Pallets: For industries requiring additional safety standards.
🛠️ Additional Considerations
🌡️ Binding Agents: Adhesives like urea-formaldehyde or phenolic resins (8-12% of raw material weight).
📊 Output Capacity:
Depends on Process Setup and Quality.
🔄 Automation: Automated feeding, discharging, and stacking systems improve efficiency.
