What is the working principle of CNC servo hot press machine?

With the reduction of wood, especially precious wood resources. More and more furniture using thin wood or stickers and other pressure process. Hot press machine as an important equipment of pressure process. Often used in furniture manufacturing veneer and pressure molding parts. Its production capacity and technical performance limits the production scale and product quality of enterprises.

In order to better understand and choose the hot press. This paper introduces the working principle of the veneer hot press commonly used in furniture industry in detail.

In fact, the working principle of hot press machine is positive pressure on the basis of negative pressure, with special glue for processing.The hot press also has the characteristics of high pressure, low temperature and short film pressure time, which solves the deformation problem of the workpiece processed by the negative pressure equipment, greatly reduces the deformation degree of the workpiece, and ensures the quality and performance of the product.

The existing hot press hot backup on the market can automatically complete the processing technology of entering, lifting, heating, vacuum, forming, demoulding and descending. Mainly driven by oil pressure and compressed air, so there should be enough air pressure and gas. The frame is composed of steel plate and the overall structure is reasonable. Both workstations can be recycled or used separately.


Sinoeuro hot press machine is widely used in furniture production, wood doors, wood-based board secondary processing veneer factories. Hot press can be said to be one of the main machinery of woodworking machinery. The main function of hot press in wood products processing is hot press adhesion furniture board, building partition, wood door, fire door surface material veneer, etc. The wide application of hot press is mainly reflected in plywood, woodworking board, medium fiber board, particleboard, a variety of decorative materials, decorative cloth, wood veneer, PVC and other wood-based board applications, can also be used for veneer drying, leveling, color decorative board leveling, forming, the effect is very significant.

The press host can be divided into three parts: heating system (to provide heat source), hydraulic system (to provide pressure and control pressure. And press body (frame, control part). In general, hot presses are evaluated and selected mainly based on functionality, reliability, service and price. This paper mainly introduces the function and reliability of hot press.


Hot press itself production problems are not many. But a large part of the hydraulic system. Such as oil leakage and failure to maintain pressure. A lot of knowledge and requirements about the hydraulic system can not be described here. But in the selection must be paid great attention to.


The control system of hot press mainly controls the work of heating system and hydraulic syste. And its sensitivity and accuracy directly affect the accuracy of the work of the press. Because of the complexity of the control part, it is often a problem area. For presses with complex functions, such as vacuum coated veneer presses. Many domestic press manufacturers import foreign control systems directly. And minimize the use of low-reliability control components such as solenoid valves. Generally speaking, the hot press used in the furniture industry can consider the function. Reliability of the work from the above aspects. There will be a lot of veneer process problems in the production to be analyzed according to the specific situation.

Sinoeuro Machinery remind you to properly clean the joinery board hot press. Therefore, we need to clean the hot press regularly. Before cleaning the joinery hot press, the staff should make the corresponding cleaning preparation and turn off the power supply. The hot pressing range needs to be cleaned, which can effectively prolong its service life. Check whether the switch is connected properly and whether there is oil leakage. Also, check for anomalies before starting operations each day.
