Product Name:Top-down Single-layer Hydraulic Press Machine


Top-down single-layer hydraulic press(900T-3200T)

For this type of press machine, the oil cylinder is set above the heating plate. When it is pressing board, the moving of oil cylinder is from up to down. The press board falls down by the gravity itself. The pressure of in-head type single veneer press machine is start from 900T, and the maximum can be 3200T. The temperature of press machine would be controlled automatically. This type of press machine is mainly used in the veneer processing of high-end plate material for customers’ special requirements, and it can process the plate which is less than 6mm. The plate material that it can process mainly includes: solid board, multi-layer solid wood board, solid wood finger-board, compositive board, particle board, solid particle board, large particle board, low and medium density board, veneer board, ecological board, core-board, and so on.

The main features of in-head type single veneer press machine are: compared with underneath type single veneer press machine, its speed is faster and the veneering effect is better. Because the oil cylinder moves from up to down, the closing speed of press machine is faster. This would shorten the whole working period of the machine. The machine would be possible to add auto feeding system later when our customer need. So it can realize the purpose of reducing labor, improving working efficiency and saving cost, and so on.


1: Aging Treatment:  After we finish welding of the main frame of the press machine, we give them a aging treatment. After this step, the stresses of the main frame became more uniform and the using life of the frame can be 1.5-2 times more than before.

2. Frame Mechanism: Some other brand press machine internal stress concentration region was grinded by artificially after cutting, edge stress concentration easily damaged, but we use CNC machining center creates the shape make a very smooth surface. This would increased strength and fatigue life, make the frame more persistent. 

3. Insulation Mat :The machine uses macromolecule inner temperature insulation board instead of epoxy resin plate, so that the index of withstand voltage and heat-resisting is increasing obviously. It would reduce the temperature of the oil cylinder,  to extend the service life of the sealing ring of the cylinder.


For common press machine, the accessories can choose following kinds:

A: Fast hydraulic system: We improved the original hydraulic system. We increased the pressure energy storage device and redesign the valve block system. All the valve and pipe are used by larger sizes, This would make the oil cylinder down faster, and shorten the closing time of the press machine and increase the board production. Meantime, we changed our hydraulic oil cooling method, using air cooling hydraulic pump station instead of water cooling hydraulic pump station. The oil temperature can be reduced 10℃ extra than before.  In the same operation conditions. Our machine more stable and have longer service life.  

B: Asynchronous servo motor for energy saving purpose: There are two advantages by using asynchronous servo motor. One is the energy saving can reach about 40%, The other is when the machine in the pressure holding operation, motor and pump stop working. So it can increase about 50% of service life of the pump and valve of hydraulic system.

C: Electronic automatic temperature control system: The installation of electronic automatic temperature control system solved that the up and down heating plate need to be adjust the temperature manually. It would adjust the heating temperature automatically. The temperature of the up and down heating plate is always maintained at the client set temperature range.

D: Recirculation System: Heat conducting oil recirculation system use high temperature oil heat pump and imported electric three way valve or pneumatic valve, match with imported PMA temperature control instrument. This would make a heat-conducting oil furnace to produce different temperature without interfere each other. The temperature can be controlled within 1 ℃ . The temperature is more exact in the balance of up and down hot press board’s temperature. So the quality of the finished board is better.  

E: Automatic Board Feeding System: It would greatly saved the labor cost , which makes the unloading and loading board more safety and efficiently.
