Which manufacturing process is used to create MDF?

MDF, or Medium Density Fiberboard, is primarily created through the process of gluing and compressing wood fibers or sawdust. In this manufacturing method, wood fibers are broken down into small particles, which are then mixed with adhesives and compressed under high pressure and temperature to form boards. This process allows for the creation of a dense, homogeneous board that can be easily machined, painted, or finished, making it a popular material in furniture and cabinetry.

The other processes listed do not align with how MDF is produced. Carving solid wood involves shaping or cutting out pieces from whole timber, which does not involve the use of wood fibers or sawdust. Sawing and pressing logs refers to a method used for solid wood products like lumber, which is different from the engineered board that MDF represents. Layering thin sheets of wood describes methods used in products like plywood rather than the fiber-based approach used for MDF. Therefore, the gluing and compressing of sawdust is the accurate description of the MDF manufacturing process.
