The multi-layer board is a three-layer or multi-layer board material made of wood segments that are cut into veneers or sliced ​​into veneers, and then glued with adhesives.

1. Multi-layer board, also known as plywood, is a common furniture material. Generally, a single odd-numbered layer is used to bond adjacent veneers to each other in the longitudinal direction. Usually, its crown plywood is symmetrical with the inner plywood on either side of the central layer or core. Common three plywood, five plywood and so on. Plywood can effectively improve the utilization rate of wood and is an important material saving method.

2. Advantages of multi-layer boards: It is better to use multi-layer boards of all eucalyptus. The natural characteristics of eucalyptus are high density, high compressive strength, not easy to crack, deform, and will not expand and dry under various temperatures. And other issues. Environmental protection: the multi-layer boards are all natural wood, which can adjust the indoor temperature and humidity, and is easy to install.

3. The manufacturing method of the multilayer board is usually to use the inner layer pattern and then use the printing and etching method to make a single-sided or double-sided bottom plate. And put it into the designated interlayer, heat, pressurize, bond, and the final punching process is the same as the electroplating process of the double-layer board. These basic manufacturing processes have not changed much compared to the process in the 1960s, but with the development of materials and process technology, such as: bonding technology, solving the glue slag produced when drilling, film improvement), so The properties of the attached multilayer sheets are also more diverse.

Expanded multi-layer board is one of the commonly used materials in furniture processing enterprises, and it is a kind of artificial board.
