The number of plywood hot-pressing cylinders is multiplied by the cross-sectional area of the cylinder and then multiplied by the pressure.
For example: 4 cylinders, each cylinder diameter 320mm, working pressure 25MP
3.14*1.6*1.6= 8.0384mm²*25MP=200.96*4pcs=803.84
8.0384mm²*25MP=200.96
200.96*4pcs=803.84
The total pressure of the four cylinders is 803.84 tons
For example: 2 oil cylinders, each with a diameter of 360mm and a working pressure of 25MP
3.14*1.8*1.8=10.1736mm²*25MP=254.34kg*2pcs=508.68
10.1736mm²*25MP=254.34
254.34*2pcs=508.68
The total pressure of the two cylinders is 508.68 tons
For example, 4 oil cylinders, each cylinder diameter 160mm, working pressure 15MP
3.14*0.8*0.8=2.0096mm² *15MP=30.1440kg X 4=120.5760KG
2.0096* 15=30.1440kg
301440* 4=120.5760kg
That's 120.576 tons
MINGHUNG heat press machine is suitable for 4*8 feet, 3*6 feet multi-layer plywood heat press machine is suitable for hot pressing forming of plywood, multi-layer board, decorative panel, building formwork, bamboo plywood, etc. Load the hot-pressed blank or wood-based panel substrate pasted with decorative paper or natural veneer into the machine. Semi-finished products or finished products after secondary processing, this equipment is an indispensable equipment for the production of plywood products, and it is also a key equipment.
MINGHUNG Features of heat press machine / hot press machine:
This machine has a wide range of uses, and can be used for hot-pressed jigsaw panels or ordinary veneers. With automatic feeding table and discharging table. The effect of continuous work can be achieved. Save work cycle, easy and reliable operation.
Gluing of plywood refers to the process of curing the glue layer after a period of time under the action of a certain temperature and pressure. During this process, the protein glue gradually solidifies, and the molecules of the resin glue gradually condense, and finally form a body-like structure. of macromolecules.
Gluing process: In order to facilitate wetting, the adhesive is generally applied (or sprayed) to the surface of the material to be bonded in a liquid state. Adhesives in the liquid state have almost no shear strength. Therefore, after infiltrating the surface of the adherend, the liquid adhesive must turn itself into a solid through an appropriate method to be able to withstand the force. The process of turning the adhesive of the sticky body into a solid state by various methods is called solidification. For solvent-based adhesives, emulsion-based adhesives and hot-melt adhesives, they can be solidified by physical methods, such as solvent evaporation, emulsion aggregation, and melt cooling. For thermosetting adhesives, it is chemically polymerized into a polymer solid. In the glued product, the solidification of the adhesive must be maintained for a period of time under a certain temperature and pressure.
In early December 2025, the culmination of close collaboration between the MINGHUNG foreign trade team and our partners — 9 containers fully loaded with the core equipment for a plywood production line .

What is a veneer dryer?MINGHUNG Roller veneer dryer for drying original wood veneer, remove abundant humidity, in the end, the wood veneer humidity will be 5%-10%, so it is suitable for making plywood.Veneer roller dryer are suitable for big drying capacity per day, it can be different length, width
Particleboard (also known as chipboard) is a common engineered wood panel made by mixing wood fragments or particles with adhesives (such as urea-formaldehyde resin) and then hot-pressing them into shape.
