A compressed wood pallet plant can manufacture a variety of pallet sizes with different load capacities depending on the press capacity, mold design, and raw material composition. Below is a general guide to pallet sizes and their corresponding load capacities:
Standard Pallet Sizes and Load Capacities
| Pallet Size (L x W x H in mm) | Load Capacity (kg) | Applications |
| 1200 x 1000 x 130 | 1000 – 1500 (Static Load) | General storage, export, warehouse logistics |
| 500 – 800 (Dynamic Load) | ||
| 1200 x 800 x 130 | 800 – 1200 (Static Load) | European pallet standard, ideal for EU markets |
| 400 – 700 (Dynamic Load) | ||
| 1100 x 1100 x 130 | 800 – 1000 (Static Load) | Widely used in Asian and Australian industries |
| 400 – 700 (Dynamic Load) | ||
| 1000 x 1000 x 130 | 800 – 1200 (Static Load) | Used in global export and industrial applications |
| 400 – 600 (Dynamic Load) | ||
| 1200 x 1200 x 130 | 1200 – 1800 (Static Load) | Heavy-duty applications like machinery export |
| 600 – 900 (Dynamic Load) | ||
| 1400 x 1200 x 130 | 1500 – 2000 (Static Load) | Large-scale applications, bulk packaging |
| 700 – 1000 (Dynamic Load) | ||
| 800 x 600 x 130 | 600 – 800 (Static Load) | Small goods, lightweight logistics |
| 300 – 500 (Dynamic Load) |
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.Β
Β π οΈ Additional Considerations
- π‘οΈ Binding Agents: Adhesives like urea-formaldehyde or phenolic resins (8-12% of raw material weight).
- π Output Capacity:
- Depends on Process Setup and Quality.
- π Automation: Automated feeding, discharging, and stacking systems improve efficiency.
