Introduction of handheld ultrasonic spot welding machine


Ultrasonic spot welding machine converts 50/60 Hz current into 15, 20, 30 or 40 KHZ electric energy through an ultrasonic generator. The converted high-frequency electric energy is again converted into mechanical motion of the same frequency through the transducer, and then the mechanical motion is transmitted to the welding head through a set of horn devices that can change the amplitude. The welding head transfers the received vibration energy to the joint of the workpiece to be welded. In this area, the vibration energy is converted into heat energy by friction to melt the plastic.


The short pressure maintained on the workpiece after the vibration stops causes the two weldments to solidify into one body in a molecular link. Generally, the welding time is less than 1 second, and the obtained welding strength is comparable to that of the main body. Your company focuses on introducing handheld ultrasonic welding machines, also known as pistol ultrasonic spot welding machines.


Ultrasonic advantages of pistol ultrasonic spot welder:

1: It can be used for butt welding of thermoplastics, and the welding head can also be replaced according to customer needs for riveting, spot welding, embedding, cutting and other processing techniques.

2: Instead of traditional processes (such as gluing, electric perm or screw fastening, etc.), it has high production efficiency, good welding quality, environmental protection and energy saving.

3: Replace the flux, adhesive, nails or other mechanical fixing methods required in the past production, thereby improving production efficiency and reducing costs.


Ultrasonic use of pistol ultrasonic spot welder:

1: Used for welding, riveting, spot welding of thermoplastic products, as well as inlay and edge pressing processes between metal parts and plastic parts.

2: Used for plastic hardware, riveting, spot welding, folder positioning, underwear equipment, underwear machinery.


Ultrasonic characteristics of pistol ultrasonic spot welder:

1: Eliminate pinholes caused by traditional sewing.

2: Use vibration to rub or cut, no smoke, no peculiar burnt smell, eliminate the danger of high frequency, eager machine and air pollution.

3: It can be processed after starting up, no preheating is required, easy to operate, continuous processing speed, high efficiency, and labor cost.

4: Ultrasonic vibrator has strong output, high efficiency, low welding head temperature and stable machine quality.


Suitable for the welding of thermoplastic thin materials. Applicable materials: synthetic chemical woven fabrics, including chemical woven blended fabrics such as T/C6533 plain woven fabrics, knitted fabrics, nylon fabrics, Tedlon fabrics, non-woven fabrics, glitter fabrics, artificial leather, PU, satin Cloth, PS, PVC, PE+paper, TR and various films covered or laminated woven fabric.


How to use the handheld ultrasonic welding machine:

1: Connect one end of the cable to the output control cable connector on the vibrating tube, and the other end to the output control cable socket on the back of the electric box, and tighten it.

2: Wipe the connecting surface of the welding head clean, connect it to the transducer of the vibrating tube, and lock it with a wrench. Note: When connecting, make sure that the two connecting surfaces between the welding head and the transducer are consistent and locked. Do not allow the connection screws to be too long or the sliding teeth cannot be locked, otherwise the sound wave will not be transmitted smoothly and cause damage to the machine.

3: When loading and unloading the welding head, two wrenches must be used to clamp the welding and transducer respectively, and one of the parts must not be locked or loaded or unloaded to avoid damage to the portable vibration tube.

4: After checking that the points 1 and 2 are properly installed, plug the power cord socket into the external power socket, and flip the power switch, then the power indicator light is on.

5: Lightly press the sound wave control switch. At this time, you can hear the "squeak" sound of the welding hair when the sound wave is transmitted to the welding head, indicating that the machine is working normally and can be put into use.

6: When the machine is working abnormally, do not disassemble the equipment privately, please notify the supplier or send the equipment to the manufacturer for inspection and maintenance.
