What is Blockboard and the Manufacturing Process of Blockboard

Blockboard (also known as lumber core) is an artificial board, i.e. an artificial board that looks similar to plywood, but the center layer is made from softwood strips. The design of the blockboard is achieved when the strips are put in every corner and sandwiched between veneers of softwood, hardwood, or MDF, pulp under extreme pressure, and heat with glue.

Now that you understand what blockboards are, let’s dive into their manufacturing process.

The followings are The Steps of Blockboard Processing:

  1. Acquiring raw materials, i.e. timber. 
  2. Slicing Wood/ Rotary Cutting. In this process, the logs of lumber woods are sliced at 25mm or as per industry standards. 
  3. The next process is gluing, in which slices of glue or adhesive are used to attach the sliced wood. 
  4. The blocks are then left for drying to reduce the moisture. After successfully drying, they are ready to make a sandwich.
  5. The next step involved is attaching the blocks. They are attached after deciding which block boards are required, i.e. softwood or hardwood. 
  6. Finishing is given with lamination, brand printing, and coating for high durability at the final stage.
