Production process Multi-layer glued bent wood furniture is developed on the basis of plywood production process and bent wood process. It uses log sliced ​​or peeled veneer as the main material, and then a stack of glued thin boards or thin wood is made into a certain thickness of blanks according to requirements, and then after drying, gluing, hot pressing and other processes, molded, glued and bent into shape (this processing method is also called molding gluing), and then made into high-end and mid-range furniture.

The development of multi-layer glued bent wood furniture has a long history and has gone through three development periods. As early as in ancient times, humans sawed and bent wood and cross-connected it to make curved parts of furniture. In the 1850s, Germany pioneered the bent wood process. With the rapid development of veneer peeling and planing technology, and the widespread use of artificial boards, by the 1930s, the Finns successfully developed a new multi-layer glued bent wood process. Since then, multi-layer glued bent wood furniture has gradually developed. However, the wood texture of furniture parts that are sawed and cross-connected is not smooth, the strength to withstand static bending pressure is weakened, and it is labor-intensive and requires more materials. The wood utilization rate in the production of bent wood furniture is only about 25%, the scrap rate is high, and the materials are strictly controlled. Only a few species such as elm and ash are available. The emergence of the new multi-layer glued bent wood process truly shows its vigorous vitality.

Significance The new multi-layer glued bent wood technology replaces the old solid wood bending technology, which simplifies the complicated processes of sawing, planing, drilling, and mortising of solid wood bending, improves the utilization rate of wood, improves work efficiency and labor productivity, and has higher strength than solid wood structural furniture. It can be disassembled and assembled, and is easy to produce, store, package and transport, which is conducive to the specialization, mechanization and automation of furniture production, and is conducive to improving the economic benefits of enterprises. Multi-layer glued bent wood furniture integrates and develops the advantages of both plywood and bent wood processes, creating conditions for the production of furniture series. Its birth marks the progress of furniture technology, and has promoted the beautification of furniture shape, the increase of furniture varieties, and the replacement of furniture.
