Particle board manufacturing process

Particle Board is an agricultural residue based engineered wood. It is manufactured from wood chips, saw dust, bagasse, coconut shell waste, cotton stalk rice husk and many other agricultural wastes with suitable binder resin.

Particle board has been in use since the 1940s, often used in place of the more expensive plywood in furniture manufacturing, building partitions etc .Particle board is also ideal for applications such as photo lamination, packaging box TV cabinets, dressing tables etc.The process of making particle board begins with Agriculture and wood waste. Most Indian particle board manufacturers use saw dust, wood chips collected from saw mills and other woodworking factories.

Particleboard is manufactured by mixing wood particles or bagasse with resin and forming the mix into a sheet. There are several types of resins that are commonly used. Formaldehyde based resins are the best performing when considering cost and ease of use. Urea Melamine resins or phenol formaldehyde resin is used to offer water resistance. Once the resin has been mixed with the particles, the liquid mixture is made into a sheet. A weighing device notes the weight. The sheets formed are then hot-compressed under pressures between two and three mega Pascals and temperatures between 140 °C and 220 °C. This process sets and hardens the glue. The boards are then cooled, trimmed and sanded. They can then be sold as raw board or surface improved through the addition of a wood veneer or laminate surface.

Particle Board Applications

  • High resistance to abrasion
  • High moisture resistance
  • High resistance to heat, steam and stains.
  • High strength to weight ratio.
  • Strep vertical density gradient, which gives a higher bending strength to the board
  • Economical board sizes resulting in minimal wastage.
  • High degree of consistency in quality.
  • Apart from this our particle boards are termite resistant.
