Famakafakana mialoha: ny lamin'ny fampiroboroboana ny plywood any Shina sy ny fifantenana ireo tsipika fanerena fisaka tsy mitsaha-mitombo sy tsipika maromaro.
Continuous flat pressing technology is the greatest invention of the wood-based panel industry in the 20th century, which has basically overturned the traditional production process of fibreboard and particleboard and completely changed their production mode. In the mass production line market, it has completely replaced the traditional fibreboard and particleboard multi-layer press production line model (except) and completely dominated the world production pattern of man-made boards, becoming the representative of advanced productivity of today's wood-based board industry. Since the emergence of the continuous flat press, developed countries have been trying to apply the technology in the plywood industry. Generations of researchers have worked hard to realize this dream, but no substantial progress has been made. Many excellent companies have withdrawn from the wood-based board market in disgrace in order to innovate the continuous flat pressing of plywood. What is the main problem? China's tsipika famokarana plywood model where exactly to go? It is the main problem that needs to be solved in the theoretical world of man-made boards.
Plywood production is the largest industry in the world's wood-based panel industry. Plywood accounts for 60% of China’s board products. With 70% of global plywood production being produced by enterprises, it is of international significance to explore the plywood production model.
Raute is the world's plywood giant (the world's leading manufacturer of plywood equipment) and one of the world's three giants of wood-based panels alongside Siempelkamp and Dieffenbacher. Raute is a specialist in the development of plywood equipment and has plywood lines all over the world. Raute's lines represent the high-end products of the world's plywood industry. Raute's double- and single-shaft rotary cutters make up the stock preparation section. The fully automatic veneer hole filler and veneer splicer make up the forming section. The multi-layer presses form the forming section. After starting with the Raute plywood production line in the Yakeshi integrated plant, Raute has now achieved strategic development in the high-end wood-based panel production line. At the same time, the original large Chinese plywood production line was also transplanted from the Raute model.

Raute's rapid entry into the market provides technical support to improve the quality of plywood and increase the added value of plywood.
The Linyi model refers to the plywood machinery industry represented by Sinoeuro Machinery in the Linyi area. They have completely adopted the model of producing plywood using the equipment produced in Linyi as the main component of the production line and using the process they have created. They have broken through the shackles of the current academic plywood manufacturing science and abandoned the Raute model of equipment combinations. They have completely innovated a new process for plywood, in particular the production process and production line model of rolled board + paving line, core board finger joint + cross-patch.
Sinoeuro machinery is not only vigorously promoted in China, but has gone global. According to experts, some new plywood factories in Southeast Asia, Africa, the Middle East, Russia and Turkey are now copying the "Linyi model": importing Linyi's equipment, using Linyi's technology, recruiting Linyi's factory manager, buying Linyi's auxiliary materials and using Linyi's wood veneer. In the academic world of wood-based panels, the Linyi plywood industry is considered to be a model of innovation in the same way as Raute. But "existence is justified", and the Linyi model used their innovative industrial mechanism to produce 90% of the plywood, forcing down such giants of the plywood industry as Songjiang Plywood Factory, Changchun Plywood Factory, Shanghai Fuhai Wood Industry, New Climax Wood Industry and Guangdong Jiali Wood Industry, who made an indelible contribution to the plywood industry back then.
Dieffenbacher has been advocating the use of continuous flat presses in the forming section of the plywood industry. They are trying to turn the forming section of the plywood industry upside down, just like fibreboard and particleboard. A professor visited a Dieffenbacher model LVL line in Australia more than ten years ago. His view was that such lines are not viable, at least not without solving the problems that exist now. They have their own set pattern of forming and continuous flat press moulding, which is fine in Australia. It needs to be significantly improved before it can be adapted to the market. LVL is now available at over $5,000 per cubic metre using imported raw materials, or can be exported altogether. Foreign continuous laminating systems are convertible between LVL and plywood, and one production line can produce two products. However, the articulation of Chinese plywood veneer is not easy to solve, and there will be many problems with direct transplantation to China, so the introduction of manufacturers must be careful.
The greatness of the Linyi model
Linyi City, Shandong Province, is located at the border of Shandong and Jiangsu provinces and is a submerged secondary forest area without raw material resources for the development of the wood-based panel industry. Linyi's initial wood-based panel resources consisted mainly of forest protection and renewal, roadside planting and nurturing, contracted forest land in the submerged mountains, secondary and fast-growing forests, and industrial timber forests all cut. At present, Shandong Province is promoting the transformation and upgrading of traditional industries, including the wood industry. Linyi has seized the opportunity to focus on promoting the development of an innovative model for the wood-based panel industry. As the largest cluster hub in the northern China, its well-developed logistics industry has structured the raw material purchase and plywood product output chain of Linyi's wood-based panel industry, giving rise to the rapid development of Linyi's wood-based panel industry cluster economy. At present, Linyi has become the largest wood-based panel production base in the country, the world centre of wood-based panel production and the mecca of the plywood industry.
The main feature of the Linyi plywood production model is that the main equipment of the preparation section is the milina peeling veneer tsy misy spindle.
The surface veneer and the core veneer are all the work of the spindleless veneer peeling machine. When the surface board is unevenly thick or thin, it can be smoothed by the sanding machine. The core board does not need to be considered for lateral strength and is ready when there are no defects on the exterior. Veneer drying relies mainly on sunshine. Veneers with broken raw materials, not into sheets and difficult splicing are produced in small veneer. The core veneers are then joined by Linyi's local core veneer composer machine and a finger joint builder machine invented by Sinoeuro Machinery. (Sinoeuro Machinery is a professional plywood machinery manufacturer in China with 26 years experience. They can provide professional service and help in plywood production.) This production model forms the main body of the Linyi model.
Low prices and high requirements are the greatest competitiveness of the Linyi model, and non-standard specifications are the heavy products that exist in the Linyi model. The Linyi wood-based panel machinery industry has created the splendour of the Linyi model. The Linyi model is the embodiment of the socialist market economy. The competition between the Linyi model and the Dieffenbacher and Raute models is the competition between the socialist market economy and the core values of Europe and America. Linyi's success maps the success of the model in the world. Therefore, the Linyi model is the most successful model for wood-based panel in the world in the 21st century.
