Guidelines about Hot Press Machine for Plywood

Plywood is a kind of wood-based artificial board made of a combination of three or more layers of (usually asymmetrical) veneer and gluing the fiber direction of the adjacent veneer vertically. It is made by a series of plywood making machines. Plywood is widely used in construction, furniture, carriage, shipbuilding, military industry, packaging, and other industrial sectors due to its advantages of large format, small deformation, low war page, large transverse tensile strength, and convenient construction and application has gone.

Hot Press Machine for Plywood

Hot press machines are one of the most popular devices in the woodworking industry. Now all factories have a staple that engages in the manufacture of plywood, these state-of-the-art systems are strong in their output. Although the machines differ in capacity, an average Hot Press Machine is about 120 tons. Based on their model and make, these units have a compact design and great pressure efficiency. A plywood making machine from a top brand guarantees both speed and accuracy.

Hot Press Machine for Plywood is one of the main equipments in plywood making machine. It is a tool used for hot pressing and gluing of slabs after glue assembling. Typically, different types of plywood have different requirements for hot press performance. The pressure required to manufacture ordinary plywood, aviation plywood, plastic plywood, laminated plastic board, and ship plywood increases in sequence. Such plywood making machine is divided into two types: periodic type and continuous type according to the mode of operation.

The performance of the Hot Press Machine for Plywood has certain characteristics. This type of plywood making machine has a wide range of applications, and can be used as a hot-press puzzle or as a common veneer. With automatic feeding table and discharging table can achieve the effect of continuous work. Save work cycle, easy and reliable operation. Plywood bonding refers to the process of board culture under a certain temperature and pressure, after a period of time, to complete the curing process of the adhesive layer, in the process, the protein glue slowly freezes, and Resin gum molecules slowly condense, and eventually form a body structure larger molecule. During the gluing process, the adhesive is typically applied (or sprayed) to the surface of the bonded material in a liquid state to facilitate infiltration. Liquid adhesives have almost no compressive strength.

Therefore, after the liquid clings to the surface of the adherence, it must be turned into a solid by an appropriate method to withstand the force. Curing is the process of converting adhesives into a solid state in various ways. Solvent-based adhesives, emulsion-based adhesives and hot-melt adhesives can freeze by physical methods such as solvent evaporation, emulsion aggregation, and melt cooling. For thermosetting adhesives, it is chemically divided into a polymer solid. In glued products, the adhesive must be kept at a certain temperature and pressurized for a period of time.

Common Features of Hot Press Machine for Plywood:

Although everyone has the same primary function, their characteristics vary from one to the other. All plywood making systems are hydraulic in nature. The hydraulic technology integrated with these machines is of the most advanced variety. One advantage of using a machine with high hydraulic technology is low power input. These systems do not consume much energy despite their production. Therefore, no matter the amount of output it produces, it requires very little electrical input. Operated with oil circulating pumps, these machines can channel oil internally through all their parts for auto-maintenance.

Even in terms of performance, these machines are on top. Packed with hydraulic technology, a Hydraulic Hot Press Machine is designed to deliver. The high performance of the machine is due to its engineering design. Set with plates as thick as 42 mm, these systems also produce pressure. To protect against leaks, the systems are calibrated with hydraulic cylinders that are leak-proof. Therefore they are expected to perform at a constant rate and speed, regardless of the products used in the machines. However, the best is that it gives users complete control over the pressure applied on the boards.
