III. General Information
Use
Our press machine is the corollary equipment. The operating principle is make powdered material
sample into standard specifications disk type by high pressure, so that the user can easily do
component analysis to it.
Our press machine can use to all kinds of ways to press samples, such as boric acid, steel ring,
aluminum cup and plastic ring. Notice: Different ways need different moulds.
The dimension of the sample getting from our press machine is range from 20mm to 60mm.
Different dimensions need different moulds except the plastic ring mould. The standard dimension of
boric acid mould is 40mm, and the dimension of steel ring is 45mm (Thick-wall) or 40mm (Thin-wall).
When the sample is powdered, the granularity must be more than 200 meshes and the sample must
have caking characteristic or have ruggedness by adding binder.

IV. Installation
Preparatory Work before Installation
Before installation, check the machine for damage and loose parts. The unit should be located in
a laboratory or clean industrial environment. The machine should rest on a level and flat surface
so that it will support the unit without shaking.
Install the tool tray with screw on the left of the unit. (3 of Fig.2)
Before use, you must screw off the tank filler cap first and take out the sealing plug and then
screw on the tank filler cap.
Check the oil level (7 of Fig.4); the fluid should be filled just above the middle level of the
indicator. Otherwise fill with YB-N46 anti-wear hydraulic fluid. (1 of Fig.4)
In order to guarantee the reliable work and longer service life of the oil pump, please
i
do not use any other type of hydraulic oil which we don’t permit and ensure the
cleaning and quality of the oil.
Before use, please wipe off the antirust oil on the surface of the unit and mould. But don’t use
cleaning agent with corrosive. In addition, please apply a little grease to the holes and cylindrical
surface of the press head of the mould except the plastic ring mould.
Install power line and set properly the earthed.
Switch on the power when the press tool has not been installed. The PLC starts to finish initial,
then you can see the homepage.
Press down the lifting button or falling button, then the motor starts up. The head of piston rod
should have up or down movement at this time. If not, please power off and adjust the power
phase sequence.
If normal, please press on the lifting button and keep it down, observe the changes of needle of
pressure gage at the same time. The hydro-cylinder piston keeps up going. When the needle of
pressure gage starts uplift, stop pressing the button at once. Now, the piston should have been

- 6 -
up going to the top of the hydro-cylinder. Press on the falling button until the sound of oil pump
starts to change. Redo three times as above to exhaust air in the hydro-cylinder.
Set press tool type, holding pressure and holding time. According to the page prompt, you can
complete the parameter setting.
Adjust the action of adding pressure slowly. Rotate the throttle valve (6 of Fig.4) on the hydraulic
unit properly in a clockwise direction, switch on the swing arm without installing press tool and
press the start button. The piston rod keeps uplifting to the top, but the oil pump is still running.
Now, turn back the throttle valve a little slowly in an anticlockwise direction and observe the
pressure gage at the same time. You will see pressure go up to the needed pressure and then
start to keep pressure and time it. Press on the stop button to finish the program of keeping
pressure. You can do the above action again and again until the speed of adding pressure meets
your need. During the procedure, the friction of hydraulic oil will increase and the oil temperature
will rise quickly. In order to extend the service life of hydraulic oil, the speed of adding pressure
should not be too slowly. Usually, it is suitable that the time adding pressure slowly from starting
to rising to 200KN is 2 to 4 seconds. If adjust the speed of adding pressure slowly, genially, you
should adjust the speed of reducing pressure slowly at the same time.
