Particle board, also known as particleboard or chipboard, is an engineered wood product, belonging to the wood-based panels, manufactured from wood chips and a synthetic, mostly formaldehyde based resin or other suitable binder, which is pressed under a hot press, batch- or continuous- type, and produced.

Wax prevents fibers from clumping together during storage. Chips in the case of particle board are also sprayed with a suitable adhesive before the next steps. Fibers or chips are arranged into a uniform "mat" on a conveyor belt. This mat is pre-compressed and then hot-pressed. Hot-pressing activates the adhesive and glues the fibers or chips ...
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
Veneer refers to thin slices of wood and sometimes bark that typically are glued onto core panels (typically, wood, particle board or medium-density fiberboard) to produce flat panels such as doors, tops and panels for cabinets, parquet floors and parts of furniture. They are also used in marquetry. Plywood consists of three or more layers of ...
The steaming process softens the natural lignin around the fibres which holds the fibres together in the board, which is typically manufactured to around 20mm thickness. These boards are then laminated up with a water based glue into thicker layers to produce boards up to around 120mm thick.
Although similar manufacturing processes are used in making all types of fibreboard, MDF has a typical density of 600–800 kg/m 3 or 0.022–0.029 lb/in 3, in contrast to particle board (500–800 kg/m 3) and to high-density fibreboard (600–1,450 kg/m 3). In addition, MDF typically has an MOR of 40 MPa and an MOE of 3 GPa.

Printed circuit board manufacturing is the process of manufacturing bare printed circuit boards (PCBs) and then populating them with electronic components. It involves the full assembly of a board into a functional circuit board. In board manufacturing, multiple PCBs are grouped on a single panel for efficient processing.
