Compressed Sawdust Blocks for Wooden Pallet Manufacturing

Compressed sawdust blocks, also known as composite or molded wood blocks, are engineered wood components used primarily as spacers or feet in the construction of wooden pallets, especially block-style pallets. These blocks are made by compressing a mixture of wood particles—such as sawdust, wood shavings, or chips—with a bonding resin under high pressure and temperature. Key Characteristics
  • Material Composition: Typically made from recycled sawdust or wood waste bonded with a synthetic resin (commonly urea-formaldehyde.
  • Density: High density (around 600–800 kg/m³), which provides strength and load-bearing capacity.
  • Shape & Size: Manufactured in uniform rectangular or square shapes (75x75 mm or 95x95 mm) and customizable lengths.
  • Moisture Resistance: Low moisture content (usually below 10%) helps prevent warping, fungal growth, and decay.
  • Pest-Free: Compliant with ISPM 15 standards due to the high-temperature processing, eliminating the need for additional heat treatment or fumigation.
  • Eco-Friendly: Utilizes wood waste, making it a sustainable alternative to solid wood.
