28KHz Ultrasonic Spot Welding Gun for Non-woven Welding air cooling

28KHz Ultrasonic Spot Welding Gun for Non-woven Welding air cooling

Ultrasonic spot welder gun is an essential part of the whole ultrasonic spot welding system. The transducer and welding horn temperature cannot exceed 80℃, so strong fan cooling or water cooling has to be used. We provide the ultrasonic spot gun with different parameters and power.

The welding gun K&M tech provides are of high quality and duration, and it is widely used in many application fields such as clothing fabric, underwear spot welding, clothing fabric, underwear spot welding in the apparel industry, logo, woven labels, marks welding, or spot welding, etc in the Label industry, TPU vamp positioning spot welding, shoe head wrinkles smoothening for shoe material, chicken manure belt, egg conveyor belt welding in poultry, automotive trim wrapping, trim riveting, steering wheel dustproof sleeve welding in the automobile industry, plastic parts, rubber column riveting, soundbox covering cloth welding in electronic industry, PVC spot welding, plastic box sealing welding in the packaging industry, face mask, non-woven bag welding, velcro and film welding, etc.

Conditions of Welding

Ultrasonic automotive plastics as the condition of ultrasonic welding, the most important is the time to apply welding energy (vibration, welding time) length, and pressure, of course, other conditions are also very important. Welding temperature, ultrasonic welding material viscosity, low temperature. Otherwise, the material will not melt.

With the amplitude, the higher the amplitude, the higher the temperature rise. The pressure is applied to the molded article using a cylindrical gaze. General compressed air pressure is 0.1-0.3MPa (pressure gauge), sometimes higher. But the use of high pressure will hinder the cylindrical vibration.

The welding time varies depending on the material and the shape of the product. The welding time of some molded articles is only 0.2 seconds.

Overtime will cause excessive welding and produce a lot of flash and bubble, resulting in poor airtight, must pay attention. Cooling (holding) time For crystalline plastic, if the temperature below the melting point, the connection will be solidified, usually the pressure time is maintained between 0.1-0.2 seconds. AMMA plastic).

Different Applications:

Ultrasonic riveting: the nature of metal and plastic or two different plastic bonding together, can make use of the ultrasonic riveting machine, so that the weldment hard brittle, beautiful, strong.

Ultrasonic welding: the use of ultrasound machine small welding head, the two pieces of plastic products into multi-point welding, or welding the first row of teeth on a direct pressure on the two plastic workpieces, so as to achieve the effect of ultrasonic welding.

Ultrasonic implants: the nut screws or other metal into a plastic workpiece. Ultrasonic energy through the ultrasound machine will be transmitted to the metal. The high-speed vibration and heat, the pressure in the ultrasound machine to make metal objects embedded directly into the plastic inside.
