In the production of hollow board, the thickness and material density of the hollow board should be set in the machine. The material density is also called the gram weight, which is the weight of the hollow board of 1 square meter. For example, the weight of a hollow plate of 1 square meter and a thickness of 5mm is 850g, then the weight of this hollow plate is 850g.
