Six kinds of product innovation,

1) The electric cabinet

Get rid of the traditional pressure gauge , we use microcomputer ,manually /automatic controlled electric cabinet

1. increase the sensor device
2. when overpressure it will power off automatically
3. when the voltage is not stable it will power off automatically
4. when over time It will automatic power off too
5. when the ac contactor to seize up, it will power off automatically and protect itself

2) In order to protect the cylinder and the hydraulic system, we have increase four support bases in the bottom beam .

3) In the crossbeam , we have change the slider into roller , can decrease the frictional force .

4) In order to make the hydraulic oil more clean, on one hand we have increase the sealing ring in the hydraulic system ,on the other hand we using the pipeline without welding .

5) In order to make the machine more standard , we punch the platen instead of using lifting lugs when install the hot platen onto the upper beam.

6) New electric cabinet in new pressure scope , from 300v -550v, increase the scope work .

BY21-4*8 series of pre press,used in plywood,multi-layer board,decorative panels,block board,building templates,particle board and MDF wood veneer in pre press section.

Main Advantages:

1. The use of aircraft alloy tank side note,

2.Domestic of the art hydraulic system

3..PLC programmable control system so that it smooth,rapid closure,stable,effective and preloading

4.Hot platen:It is drilled from excellent carbon solid steel and it is high precision, high strength and durable.It is manufactured on special worktable,so as to keep the hot platen easy to operate.

5.Heating system:It can be heated by steam bolier,oil heater or electri oil heater.The steam bolier is low in cost and suitable for common production,yet it is high pressure vessels,so it should be operated carefully.As to the oil heater,it is adjustable,safe, uniform temperature,energy saving and so on,yet it may cost much than steam bolier.The electric oil heater is environmental protection instead of using coal or wood as it’s fuel,but it may cost lots of electric energy.

6.Hydraulic system:It is “Triple Filter”and it has excellent oil pump and electric motor.It uses right-angled one-way valve so that it can work smoothly.The pressure is adjustble.

7.Cylinder:It is worked through excellent CNC precision machine tool.It uses high quality oil envelop so as to avoid of oil leaking.

8.Control system:Microcomputer ,Manually/Automatic controlled.It can lift the hot platen,close the separation,add the pressure,keep the pressure,keep time, descend the hot platen and so on.

The machine can make plywood,paricle board,chip board, fibreboard,decorative sheet,etc.
