> Principle of Seam Sealing
Ultrasonic energy is a form of physical vibration. The commonly used vibration frequencies are 20kHz,
30kHz, 35kHz and 40kHz. Different materials exhibit different behaviors under ultrasonic vibration. Synthetic
material generates internal heat under ultrasonic vibration. The US-511 machine generates vibration on the
surface of the horn. Fabric with at least 50% synthetic material is placed on the surface of the horn. A special
tool called cutter bit is pressed against the horn so that fabric between the horn and the cutter bit is exposed
to vibration. The heat generated in the fabric portion under pressure is heated up instantly and the
temperature is high enough to melt the fabric, hence resulting in an ultrasonic cut.
US-511 is engineered to careful manage this vibrating energy in order to slice fabric consistently in single
layer or multi-layer application.
During single layer operation, fabric is melted and separated resulting in a fray free edge. While during
multi-layer operation, layers of fabrics are cut but at the same time the edges of the fabrics are melted and
fused together resulting in a “weld”. This process is sometimes referred as a “cut and seal” or “line bonding”
operation.

> Preparation for Installation
Installation must be carried out by authorized personnel. Follow the steps below:
1. Position the machine on a flat surface and allow at least 50cm clearance on both sides as well as
the back side, this is essential for the hot air ventilation and also to allow enough room for
maintenance personnel to carry out necessary service and maintenance.
2. Adjust the foot stand so that the machine is level and stable.
3. Loosen all packing cable ties and materials in order to free up all machine movements.
4. Connect the power plug to a suitable outlet with at least 10A capacity. Make sure grounded and
reliable.
5. Locate the air hose supplied with the machine. Connect one end to the inlet of the compressed air
water filter at the back side of the machine; connect the other end to a compressed air supply such
as air compressor or central air supply. Make sure the compressed air supply has at least 0.4Mpa (4
bar) of pressure.

> Selection and Replacement of Cutter Wheel
>> Selection of the cutter wheel
According to different fabrics and process, you can choose to buy a cutter wheel with different
angle. Straight knife is 0 degree angle knife. Normally, the straight knife is easy to cut the fabric, and the
cutting surface is smooth, but have small incision fusion point. The greater opposite blade angle, the
better incision adhesion will achieve. (as shown in Figure 3).
Figure 3
>> Replacement of the Cutter Wheel
Cutter wheel is a vulnerable product. When it is difficult to cut even the pressure is increased, or fusion
point becomes very large, you should replace the cutter wheel, otherwise, high work pressure will speed up
the mold wear.
Remove the three screws which fix the wheel, then you can change the cutter wheel (shown as figure
4).
Change the position of the gasket next to the cutter wheel can move the position of the cutter wheel.
The lower wheel must be adjusted at the same time once the position of the upper cutter wheel is changed.
Otherwise it will lead to different speed in upper and lower wheel which affecting the cutting effect.

Figure 8 Parameter Page
1. Wheel start delay time setting. The time from when the right pedal is depressed to when the
upper and lower wheels start to rotate. This setting aims to prevent poor cutting result
because the ultrasonic may not function immediately at the beginning.
2. Ultrasonic stop delay time setting. Time from when the right foot pedal is released to when
the ultrasound stops. This setting aims to prevent poor cutting result because the ultrasonic
may stop earlier than the upper and lower wheels at the end.
3. Micro reverse time setting.
4. Reverse speed setting.
5. Back to main page.
6. Pressure relief time setting. When pressing the left pedal to pressurize, the air pressure
needs to be converted from working pressure to pressurized pressure, pressure relief time
refers to the time from when the left pedal is depressed to when the working pressure relief
to zero.
7. Lower wheel location setting. The location of cutter wheel may need to be changed, the

lower wheel position must be changed at the same time. Otherwise it will lead to different
speed in cutter wheel and lower wheel which may affect the cutting effect.
8. Upper wheel pressurize speed setting. When processing fabric position such as bone
position, pressurize is needed. Then the cutter wheel working speed will change to this
speed instead of the speed set in main page during pressurizing.
9. Lower wheel pressurize speed setting. When processing fabric position such as bone
position, pressurize is needed. Then the lower wheel working speed will change to this
speed instead of the speed set in main page during pressurizing.
