Problems solved by technology

[0002] Plate is an important raw material for making various tables, chairs and other required panels, and can be used to make conference tables, dining tables, leisure tables, computer tables, chair seats and backrests, bookshelves, TV stands, multi-functional combination shelves and other products At present, most of the boards of this kind of products still use solid wood boards, wood plywood, MDF, fiberboards or particle boards. Most of these boards are made of wood materials. Using these boards in large quantities is undoubtedly a kind of destruction and waste of forest resources. , with the reduction of forest resources in our country, the restrictions on timber felling, the board with wood as raw material will be restricted
At the same time, on the one hand, the quality of the board made of wood is heavy, especially the medium density fiberboard that is more commonly used recently. Its heavy quality makes it difficult to move the products such as tables, chairs, and shelves; Due to the high price of its raw materials, the production costs of the tables, chairs, frames and other products made of it are also relatively high; and the wooden boards are generally not made into specific shapes. It needs to be processed according to specific shape and size requirements, which undoubtedly increases labor costs and waste of edge materials
